We're a little crazy, about science!

More experimental prep

Is this our setup or is this electronic equipment from the late 50’s? I’ll never tell… (okay, let’s be real, this is a lot nicer looking than our cable mess).

Things have been busy, welcome to my life. But seriously, there is a lot happening right now, most of which is top secret (shhh don’t tell anyone). But as usual, leading up to an experiment, there’s a lot of prep work that needs to happen. Mostly because things always go wrong and we want to maximize our chances for them to go right. So let’s dive into what it’s like the second time.


Data mountain

Well the week is over and I’ve barely been able to drag myself out of bed it’s been so exhausting. Unfortunately, we’re doing it all again next week too, so it’s not over yet. But the first of two test experiments are done, I say test because these don’t actually count toward our original set of experiments we’re doing later this summer. Meaning there’s going to be a lot of work coming my way, fun times.


More on experimental prep

I kind of wish my equipment looked this cool…

Since we have a rather large and cumbersome set of experiments happening it’s my job to make sure they go off without too much trouble. I say too much trouble because no matter how much you plan, test, and retest, something will go wrong. Heck it may not even be wrong on our end, it may be wrong on someone else’s side, but that’s why we plan. So once again I’m talking about how we prep for our experiments.


A big revision

Ever have a really good idea, maybe even a “big idea?” Well I’ve apparently had a few, but some are bigger than others and currently we’re diving into some very intense experiments using my “big idea,” but we’re running into certain limitations. While I could happily call it here, not put the effort into doing anything about it, and just live with it, that’s not happening. For anyone who knows me, that’s not even an option. So instead big idea is getting a big revision.


Making greatness

I do love making… new friends.

If you build it, they will come? Okay not quite, but if you can buy it you need to make it. That seems to be the theme for the next few weeks as we’re getting ready to start several different experiments and the scope of them is massive. Not so much the experiments themselves, but everything that is going into them and everything we are going to get out of them.


Adventures in experimental design

When did people start trusting me with experimental design? I have no idea, but here we are and I’m helping come up with a series of experiments we will be doing in roughly one week… seven days. So between now and then, we have a lot of things to figure out. We have a rough idea about what will happen, but there are a lot of moving parts and it turns out we are probably missing a few things so we’re going to have to get creative if we really want to get to the bottom of things… fun times for all!


The mysterious data

I sometimes miss the days when the answers were in the back of the book. At this point I would take even just having answers that are semi related to the questions I’m trying to work out. Being a researcher is a double edged sword. On one side, for a brief moment in history you will know something that no other person in the world knows. On the other, how do you know that it’s correct? Questioning your results is an important part of research and right now, there’s more questions than answers.


The first time is always the hardest

If something can go wrong, it will go wrong. Especially when it’s the first time. I’ve got my first dataset for my PhD dissertation, but it was a battle of wills and the technology made sure to let me know, it’s in charge here. But at the end of the day, I got what I wanted, so it’s a win, even if it’s a bit of a loss too. Frankly, I’m so exhausted right now so forgive me if this post is all over the place, well more than usual.


Experiment prep

Tomorrow is my first experiment! To get ready I have a few loose ends to tie up before the big day. Mostly I just need to write everything out, make a list of items I need to set up, organize a few things, the stuff no one thinks about when they head off to an experiment. Tomorrow is going to be bumpy, but the first time always is, so best to be prepared.


An ounce of preparation

What a week. It’s only Wednesday and it feels like it’s just never going to end. There are three major events coming up this week, meaning I will be working this weekend unfortunately, but at least I made it through the day. Tomorrow will be a major event for me, dare I say bigger than my proposal defense just two days away.


The first one

Ever look up an answer in the back of the book? The problem with research is there’s no back of the book, but typically when you do an experiment you can at least glance at research surrounding your work and make sure you’re not going completely off the rails. Because I like to make my life unbelievably difficult, and because I don’t like taking small steps forward, I’m going to (hopefully) be the first to do a few things this year. But it’s not as glamorous as it sounds.


Another OR experiment

Time to dust off my scrubs, it’s back to work for me. In fact, I have been so busy with other things I don’t think I mentioned it, but today is yet another OR experiment. With how well the previous two went, I’m hopeful that this one will go well, but a somewhat alarming email from hospital-PI yesterday may throw a wrench into any plans I had.


Dear data gods

We have offered our typical sacrifice of blood, sweat, and some might even say excessive amounts of tears. Yet clearly we have offended you and we are not sure how or why. We ask that you forgive our ignorance and help us understand how we can fix this. We are humbled and sorry, we should not seek higher truths, yet we must continue.


Mad dash to the OR

Today has been a day! The trick with doing research in the OR is that the schedule for the surgeries don’t get finalized until the day before and sometimes even then things change at the last minute. I’m not sure when the schedule was finalized or if anything changed, but this morning I got a text that threw everything out of order. The best laid plans of mice and men…


Sometimes things get cancelled

Today was a big day. We got the equipment ready, the patient consented, and everyone on the clinical side of things was on the same page we were on. Things were going well. Surprisingly well in fact, that should’ve been the first sign something was going to go wrong. This time it wasn’t our fault though! Sometimes you just can’t catch a break, so maybe next time.


Off to the OR!

Tomorrow is the big day, our second experiment and while I’m a little nervous, I’m also excited to see what we can do. Last time around we had some issues… okay a lot of issues, but that’s because it was the first time we’ve ever tried something like this. This time around we worked with the team that will be in the OR with us so we know what they are doing and this time they know what we are doing. Basically we’re aiming for a whole lot less drama and a whole lot more useable data, meaning any usable data!


A unique figure design

Over the past few weeks I’ve been hard a work making a new visualization for some of the data I’d recently processed. This again is for the project I won an award for (here), and while I’m not trying to brag, I’m super proud of how it came together. It was the first time I tried to do something like this and not only did my main-PI give me his approval it sounds like a lot of people from the lab were impressed with this as well. Unfortunately, I can’t quite give away what I did or how I did it, but I can share some of this.


Experimental limits

Well this is turning into a drama, but we keep having issues with the experiment. There are once again changes that need to be made, we’re four out of ten planned experiments into the project and while we’ve done the first four the same way, we keep trying to adjust our testing to a slightly different version of the protocol and it’s running into… issues to say the least. There are some things we just can’t accomplish using our testing paradigm and we have to accept that, but we still try to push those limits, even if it hurts.


Changing the experiment

For the past few days I’ve talked about the importance of experimental design. Well sometimes midway through you realize a better way to do things. That was yesterday when I realized the thing we were looking for in our experiment could be found a better way. I’m not thrilled about this, but sometimes it needs to happen and I think we will have a better chance of finding what we’re after if we do it this way.


Two wild days!

If you’re reading this then it’s too late for me. Or rather it’s too early for me since I need to be up super early tomorrow, which is today (when you are reading this). Confused? Well it’s supposed to be a daily blog of my progress, but I’m cheating and writing today’s post last night. That’s because really, if you’re reading this I’m in an experiment. No, it doesn’t matter when you read this as long as it’s the day I posted because I’m definitely in an experiment. Don’t worry, I’ll explain.


Experiment result preview

This summer I am performing an experiment that could change our understanding of what a certain type of stimulation is doing. It’s all incredibly exciting (as always when I’m in my Co-PI’s lab) and I get to be the first author on the result. If we can show that this thing we are looking for is true then it will be a big shift in our understanding, but more importantly it will open the door to new types of non-invasive treatments. While I cannot talk about the details (as always) I can share that I’m excited about what may be coming.


The week ahead

For a few weeks I was trying something new and doing a “week in review” well this week is exciting for a lot of reasons so I wanted to look at the week ahead! As usual I cannot give details about what is going to happen or why, but at least I can share my excitement and maybe one day soon I’ll be able to share what we did and point back to this post. So instead of looking back, today we’re looking forward. It’s going to be busy, but hey what else is new?


Start of summer experiments

Well today is the day! I’m just hours away from collecting my first dataset for my summer project. I’m excited, it’s a cool project and I get to be first author on the paper. The topic is impressive to me so I think it will be a good way to get my name out there in the field since this will be my first paper in my Co-PI’s lab (well first, first author paper). It’s a lot of responsibility and of course I don’t have any time to prep. The first experiment is always the hardest…


On designing experiments

After meeting with my Co-PI and discussing the super cool experiment he wants me to do (here) it sounds like I’m in control here. Scary thought, right? This is that whole working WITH my Co-PI and not FOR my Co-PI, he trusts me to make good choices. I mean either way he’s going to need to sign off on it when I finish the design, but it’s kind of interesting to be the one who gets the say in how we do this.


More experiments!

*Cue mad scientist laugh* It’s alive!!! ALLLLIIIIVVVEEE!! No, I’m not reanimating corpses, I just work with human participants so if they weren’t alive it would be awkward. I mean really, really awkward. Thankfully since they are non-invasive experiments the risk of serious injury is almost zero. All this build up to say I’ve got some new experiments starting today, as in MY experiments! *Cue second mad scientist laugh*


The end of the experiment

Well today was a milestone for me, the end of an experiment I wasn’t too excited to do in the first place! Of course, now comes the semi-difficult part. I need to process the data, draw some conclusions, probably publish a few papers, and get a presentation made. Things need to happen quickly too, so while I’m done, I’m not. At least, not yet.


The juggle

This wikihow image has me dying, this is exactly how I would attempt to juggle.

Every sunday without fail I make my list of tasks for the week ahead. Some of them are automated and repeat as needed, but most are specific to that week so I need to go in manually and add them. It’s nice to have everything written down in one place, in order, with times and reminders. I don’t have to stress out about remembering everything when I have a nice app on my phone that keeps me informed. Unfortunately there is a downside…


Yet more experiments?!

Sticky notes are the best.

Another long day for me. Back to back experiments (with a short break in between thankfully). It’s a lot, but I’m hopeful that after it’s all done things will slow down at least for a moment, hint they won’t. In any case, I just need to make it to tomorrow then I get a break for a few days.


A small reprieve

Well today my midday experiment was cancelled so now I have some time to relax. Just kidding, now I have time to work on the million other things I need to get done this week! That’s the problem with writing daily, a lot of it is the same stuff, but there are some minor differences with today’s list of things to do.


A week of experiments

Don’t mind me, just trying to turn back time… lol

Most times work can be a trickle, we get one or two subjects a week and that’s all. 6-8 hours in the entire week dedicated to collecting data and the rest of the time I’m free to process data, work on other things I need to do, basically live day to day like I didn’t live in a lab. Most of the time. Sometimes it’s a flood, like this week and next, then I’m reminded that I definitely need to work.


Catching up

This feels about right, I’ve been running on empty!

Sunday means getting ready for the rest of the week and what a week it will be. In my Co-PI’s lab we typically have a steady stream of people coming and going for experiments, this week (and probably next) it will be a flood. We’re trying to make my main-PI happy.



It’s going to be a busy week for me. Seems to be a theme in my quest for that PhD to be honest. I’ve got data to process, papers to write, experiments to run, appointments to keep. It’s a lot of moving pieces that all need to be aligned at just the right moment. Dominoes, if I can get everything lined up nicely, the tasks will all fall just as easy.


Experimental failure

Well that was a …flop. Today I had an experiment, had. There are a lot of moving parts when it comes to an experiment, especially in my line of research. Technology, can’t live with it, can’t live without it. Still, somedays I wish I was living in the future, one where I didn’t need to reset my router randomly. Then I would know for sure the singularity was close.


Problem solved

Sometimes we don’t need to think outside the box, the box can stay closed for the moment…

Everyone go back to what you were doing, nothing to see here! Yesterday I had an existential crisis, one that could’ve derailed my technique and any hopes I had at introducing something new into the world. With it, my PhD dissertation topic, meaning I would be over two years in and I would need to reevaluate my goals. Let’s talk about what happened!


A snag

No tears, please. It’s a waste of good suffering.

You know… that’s how it goes sometimes. You’re cruising along and everything looks great then, BAM! Totally derailed. What happened? Turns out I have a problem with my data. Not a problem persay, more like an anomaly, one that throws a rather large wrench into what WAS a perfectly running operation. Things were looking good, but now… I have a doubt.


So much data

This has basically been my progression in this project.

Well I’ve processed (poorly) about half of my data. Now, when I say poorly I just mean the visuals for it are garbage and I need to tweek the sizes and things to make it look nicer, but the idea is that I’m more interested in finding something than I am in making it look pretty. I’ve processed two of four of my subjects and well I’m excited!


The after

I’m trying to remain calm. I am an objective observer in the world of science and whatever the result, I will NOT let it cloud my emotions. I am neutral and I will remain that way… oh who am I kidding, I DID IT! Two years of planning and convincing people this would work. Then last night I had my first result, and it was a relief. It was a small step, but one I was afraid the data wouldn’t let me make.


A busy day!

Yep I use this image a lot, but it’s such a great representation of our labs work!

Well I didn’t plan for it, but today is a busy day! I’ve got a lot going on at the moment so not a lot of time to write. Let’s just talk about what I’ve done and have left to do so I can get back to it.


Process the data!

This is what raw EEG data looks like. Seriously, it’s a bunch of squiggles. However, we can make sense of it and we can even write some code to make sense of it in real-time so you can control things with your brain!!! <EVIL LAUGH>

It’s a process… that’s for sure. So you’re a scientist and you collect a ton of data, well now what? We’re talking about me of course. I did it, I collected a ton of data and now I need to do something useful with it. This is the part I wish I could skip over and get to the part where I get all the cool results, but I guess we’ve all got to start somewhere.


Day 362: Experiment two

Just a giant case full of the equipment I borrowed from my university for experiments. Pretty sure the school’s office staff thing I was robbing the place though.

Well today is going to be a quick recap of my experiment yesterday. This will be just as much for me as it is for all of you. While I can’t go into the experiment details (since I’m working to publish this) I can give a pretty good overview like I did the last time around.


Day 353: Experimental prep


Sometimes a parfor loop in just doesn’t cut it because the things you want to do in that loop aren’t allowed (like save or load data a certain way). In those cases (see above) I can run multiple instances of MATLAB and process my data much more efficiently than if I did it one at a time. In this case I had 8 subjects that needed a rather long mathematical operation performed, so I did it all at the same time. It’s a little silly, but it worked! If you didn’t know you could do that, now you do!

Yesterday I told the story of how we got to this point, a long two year journey and next week I finally get to take the next step. It’s exciting, but it also means because of my flare-up, I’m behind on what I need to do to be ready. Not to worry though, I’m taking it slow so I don’t make whatever I have worse. What goes into an experiment like this? I’m glad you asked!


Day 352: My experiment is coming!!


I just really like how this photo came out. Here’s one of my lab mates gelling the electrodes for a pseudo-experiment. The scary looking syringe has a blunt tipped needle, we don’t break the skin in our lab so no pain, just a bit of gel to wash out of the hair once completed.

Okay I’ve got an experiment update today and I’m really excited to share because it feels real finally. I know I already wrote about some of this, but when I reread my previous post, it felt disjointed so let’s go over how we got here and what’s coming. I’m excited, are you excited? I’m excited!


Day 350: In construction…


I redesigned my extruder to make it beefier, this has nothing to do with the post, but I’m really proud of it and wanted to share. Haha

Well today despite feeling like refried dog poop I have to go do experiments. It’s part of the job and to be honest I want to do it even though I feel like dried monkey vomit. I could go on, but you get the picture. I do have some more good news not related to yesterday’s news. So that is the conversation for the day.


Day 343: On lab equipment


Luckily this wasn’t my fault, but it does make for a good story now.

It was bound to happen eventually. We all knew it would, but we didn’t expect it to fail in such a spectacular manner. That is to say, all at once. One of the people I’m mentoring checked out some lab equipment since we had come up with a way to do experiments from the comfort (see: safety) of her home. That was the plan anyway…


Day 295: Back in the lab

whole brain and spinal cord dissected

whole brain and spinal cord dissected

“What do you mean, I look nervous!?”

Well it finally happened. We’re doing experiments again. It’s kind of scary to be honest to be working in a hospital again when the pandemic is going on and we have protests still happening. While I could do without the pandemic, I hope with all my heart that the protests don’t end until the corrupt system that caused them ends first.


Day 150: Surgery update

Well I’m alive, despite the VA’s best efforts. I’m struggling with some serious nausea to the point of vomiting, which has never happened to me before. I’m also in a lot of pain, but that was expected. In any case, start to finish (start as in the operating room and finish as in getting home so +30 minutes or so to the actual finish time) it took ~9 hours total good times for everyone. Anywho, I feel like death so I’ll write more later.

Day 149: An auspicious start


Well we did an experiment. I wish I could talk more about what we did, how we did, and why we did. Alas, I cannot. So instead, let’s talk about the vague how it went metric as in, maybe we found something maybe we didn’t, also this experiment highlights several quarks between the my school lab and the clinical lab.


Day 148: Experimental design



Today is day one of ten for the time that I have to do some experiments. It’s an awkward time for sure, I mean surgery, school, etc. However, that’s just the way things work in academia, I actually had a break, so I’m ready to go to be honest. Which really means this isn’t horrible timing. I’ve already discussed the million things going on these weeks, but let’s talk about what goes into experiments, really.


Day 143: Meeting with my two PI’s


Some of our exoskeletons from the lab

Today was an interesting set of events. I had my meeting with my two PI’s (which I still think would make a hilarious television show). The meeting went well, I’m very excited, but I’m also getting ready to be very, VERY busy. Let’s breakdown how it went shall we?


Day 142: So you want to record from the brain…

EEG setup

My college helping me set up for the experiment I just did. This is how we add gel to the head, there is a tiny hole by each sensor, we then insert a blunt tip needle (we do NOT puncture the skin!) to add the gel between the sensor and the top of the head to eliminate the air gap caused by the hair. Unfortunately it looks scary, but we need something tiny to get around the sensor (if you look close you can seethe tiny, tiny opening each senor has). The lights on each sensor tell us how good of a connection we have, red means bad, yellow means we’re getting close, and green means good.

Today’s post was inspired by a conversation I was having yesterday in the comment section (you know who you are and thank you for the questions). I thought I would elaborate on how we record from the brain and why. There are a lot of different ways we can do this, some of them are super invasive and others are non-invasive. In the lab I work in now, we do things non-invasively there are good things about this and bad things about this, so let’s get into it!
