Meet Lauren

Lauren is a white woman attending a southern university and majoring in mechanical engineering. She took four years of engineering as a high school student, where she studied 3D modeling and mechanics. As part of these classes, she completed a senior thesis and designed a cleaning device for the hand rims of wheelchairs:

We chose to design a cleaning device for wheelchairs because one of my best friends in ‘southern region’ is wheelchair-bound. So, I’d been out at dinner with him and he went to go wash his hands before food. When he came out of the restroom, his hands were dirty again [because] there had been something on the floor that got onto him, so I mentioned it to my ‘team partner’ when we were brainstorming ideas for our project and we were like, “Wow, let’s see if we can do something to help that.”

From Lauren’s first interview

During Lauren’s second year, one of her professors reached out to her about working as a researcher in his lab. As part of her work as a research assistant, Lauren has studied magnetic nanoparticles and has been an author on multiple papers and is tentatively planning to attend graduate school. The image below is a journey map that Lauren created summarizing some of the highs and lows from her third year as an engineering student.

Lauren’s Childhood & Family

[6-7; 23-24; 31-37; 69-75] I’ve grown up in ‘southern region’ for the grand majority of my life. I lived six weeks in ‘rocky mountain region’, but then my family moved to ‘southern region.’ My high school is right next to the local ‘southern region college’. Yeah, I had to test to get into my high school. They took our state testing results. You had to have a certain grade to get into the school, but the school was a public school. You just had to maintain a couple of other things, like you had to get a hundred service hours throughout high school, take multiple AP classes. When we did classwork and stuff, it was kind of silly, but we had to write “always my best” on the top. Everyone kind of laughed at that. They did push you to try and do really good.

[46-48; 56-58] Throughout my four years of high school, I took human geography, psychology, environmental sciences , US history, German, bio, government and macroeconomics. I also took four years of my high school’s engineering classes such as 3D modeling and mechanics. My first engineering class involved drawing a lot of diagrams, which I didn’t enjoy, but the second year we did a lot of CAD work, Computer Aided Design, and I really loved working with that. During the third year of high school, we talked about springs and motiwon and linear motion and stuff like that and we built some things. My friend and I tried to build a grabber arm for an arcade machine out of cardboard and duct tape and pneumatics. It didn’t work the best, but we were the cheapest budget.

[75; 91-92; 95-99] Then, during senior year, it was all about my senior thesis. We chose to design a cleaning device for wheelchairs because one of my best friends in ‘southern region’ is wheelchair-bound. So, I’d been out at dinner with him and he went to go wash his hands before food. When he came out of the restroom, his hands were dirty again. There had been something on the floor that got onto him, so I mentioned it to my ‘team partner’ when we were brainstorming ideas for our project and we were like, “Wow, let’s see if we can do something to help that.”. As a result, we designed the device to clean the hand rims as you rolled the wheelchair around.

[77-84; 64-67] My ‘Team partner’ and I spent a lot of time on the design project. We had three hours in class every week to work on the project and outside of class, me and her would meet up for around seven hours on the weekend to work on it and sometimes we met after class too. We used the ‘southern region college’ to 3D print parts for us. We would sand the parts down and make them cleaner and then assemble them together. We had to write a paper to go with the project and we wrote more than anyone else in the class had written, which we didn’t need to do, but we felt everything was important. We stood in the gym for a while and professional engineers and other professionals came through and listened to our spiel about the product. We had a prototype and we had a really cool bulletin board. I’m still really proud of that project. I really enjoyed the senior, engineering project, so I decided I would try and go into that for my life.

Lauren on Choosing Engineering

[14-15; 109-113] Leaving the house to go to ‘southern region university’ was pretty hard to leave my nine-year-old little sister behind because she’s so young and didn’t really understand what was happening. I picked to go to ‘southern region university’ because it was the best engineering school in ‘southern region’. I originally wanted to go to a ‘large midwestern university’, but the out-of-state tuition was too much for me and my family to afford, so I came here instead. It really is an awesome school. The local ‘southern region college’ would have been cheaper, but they didn’t have an engineering degree, so I didn’t really want to go with them. It made more sense to go to this ‘southern region university’.

[115-118; 127-130] I chose to study mechanical engineering. Based off my senior thesis, I would have gone with biomedical because wheelchairs are a medical thing, but I figured mechanical would be more general than anything else. I would get a little bit of everything, so at the end of the day, I can do whatever I want. A little bit of everything includes taking classes outside of mechanical engineering like material science classes, chemistry classes, electrical engineering classes, and programming classes. I’m not just going to know how to solve free-body diagrams.

Lauren’s Quotes #1

[137-142; 152-157] My first semester, I didn’t have many engineering classes. It was mostly like math and general education courses, but I did have to take a class called ‘Engineering 101’ and they taught us free-body diagrams and force equals mass times acceleration. It was more physics than engineering, but we had recitation classes every week where we would apply the physics to real-world stuff, at least try to. Sometimes the projects were a little sad. When we were learning about momentum, we would stack two golf balls on top of each other and drop them on the ground. At the end of the first semester, we had a project where we designed a puck launcher where we had to launch the puck across the table. You scored points based on where the puck landed on the table.

[143-149; 158-161; 165-170; 172-173] During the second semester, I took ‘Engineering 102’ where we did more stuff with circuits and harmonic motions. We were given a problem and we had to design a solution to that problem. For that one, my group got the assignment of a STEM toy. Make it so that kids enjoy learning STEM. My group made a basketball launcher game, like a tabletop basketball. You had to figure out what angle you’re throwing the ball at and what force. We chose to design a basketball launcher since it seemed to be the easiest thing that we could come up with based on the time we could all work on the project together. There were four of us to the group, but we didn’t really know each other beforehand, so we weren’t good friends and they just randomly assigned us. Our schedules didn’t match up all that well, so we only had class time to work on the project. I didn’t have as much fun as my senior thesis, but we got it done and we made a marketing video for it. We presented it to the class, and we got a good grade I also had my first mechanical engineering class in the second semester. I took a statics course that focused on free body diagrams. I still talk with some of the professors when I see them in the hall. In some instances, I would ask them how they were doing. Even though the ‘Engineering 102’ class was huge, 600 people, the professors still recognized me, and it was really cool.

Lauren’s Quotes #2

[196; 200-204] I really enjoyed the projects second year of college. My programming class involved two projects. One of them was programming a Roomba to work on Mars. I trained it to walk behind me and it could play tag. My partner and I really enjoyed working on that project. The other one was working with microcontrollers, specifically Arduino. For both projects, I was partnered with someone I had never met before. We had a lot of time to work on the project and we got dinner once together because it was dinner time while we were working on the project. We clicked and we were good friends.

[227-229; 233-239] During my third semester, one of the professors reached out to me and was like, “Hey, you were a really cool student” and asked if I would want to come work in his lab. He works with magnetic nanoparticles. I am responsible for developing simulations so that we can see if we can figure out what skyrmions look like on the inside. They are like magnetic materials that are circles and they’ve got weird shape on the inside.

Lauren’s Quotes #3

[9-18; 20-23] The start of the semester is always sort of sucky, you have to go to college, and you can’t really stay home with your family anymore. That was a little sucky, but new classes are always cool. I wasn’t super sad, that and I got to see a bunch of my friends again, so it wasn’t a horrible time. As you adjust to school, life gets easier and everything is good, because it’s easy. I collect cards, and so I was really happy when I got some new cards. I celebrated one year anniversary with my boyfriend this semester at a fancy restaurant. Yeah, that was really fun, because we don’t go out a lot, because of money.

Lauren’s Quotes #4

[9-18; 20-23] Two days after our anniversary, I got a really bad test score back, an 83.41, in fluid dynamics. And I thought I had done really well on that exam, so ah, because that sucks.

[188-199; 202-207] I think it’s an off semester for fluid dynamics, but it was still pretty big. We took over, not like one of the larger lecture halls in class, but it was a big lecture hall. I’ve talked with the teacher a couple of times. On my second test, I had two points marked off that I just had the equation re-arranged than how the teacher had it, like instead of plus X on the left hand side, I had minus X on the right hand side. When I went to go get points back, he was like, we can talk the rest of this over and see if there are any other mistakes. So, I ended up getting four points back instead of just the two I went in there expecting, which was pretty nice. He’s a really good teacher. And he really likes what he teaches, but his test have curve balls that come out of nowhere. But the class is really good. Well, he knows what he’s talking about. He’s not one of those teachers that’s like, uh. I don’t know, read the textbook. Because that’s always frustrating. Part of it is just he’s a really nice dude, and he gets really excited. I don’t know about you, but my favorite thing in the world is not how fast does water flow through the pipe in the sewer system, but he made it sound really interesting, and something that was worth learning

Lauren’s Quotes #5

[237-242] Thermodynamics was the hardest class I have ever taken. The teacher is great. He’s like my favorite teacher this semester. However, he makes everything so hard and I swear, I spend more time doing homework and stuff for that class, than I do for all four of my other classes combined. I started studying for the exams three weeks before they happened, and I still did horrible on one. But I’m enjoying the class a bunch and I really like the teacher.

[244-246; 249-253; 259-262] Also, he announced today in the last day of classes, that he was switching from being an ME teacher to chemical engineering teacher. So, I’m sort of disappointed I’m not going to have more classes with him. I mean, his class is super hard, but I can say that everyone who hasn’t quit has learned a whole bunch. I definitely know a whole bunch more now that I’ve been through that class than I ever thought I would ever know about anything thermo dynamics. And he covers a whole bunch in such a little period of time which is probably why everything is so hard on the test and stuff. We do a bunch of example problems in the class. He does a lot of proofs for the equations and stuff that we use. And just in general, the homework may have something that we didn’t explicitly talk about in class, but it helps us understand how that thing is because we have to work through it.

Lauren’s Quotes #6

[274-277; 282-290] This semester I also took a circuits class that’s required for my engineering major, and it was 100% project-based, so we would do some coding thing with what we already know and then turn in a short paper about it. Then move onto the next project. So, this semester is the first semester that they’ve structured the class as project-based. In the past, it’s been a class that’s learning how to solve circuit diagrams, which no one liked, so they’ve decided to revamp it. At the beginning of the semester, we had a couple of lectures, but for the most part, it was new projects. The first couple of projects we pulled from the instruction booklet. The booklet provides information on how you make a light blink and just really simple stuff like that. Then for a little bit, our TA was finding projects online for us to work on. Eventually, it was like, hey, look for your own projects online to work on.

[293-298; 301-311] A lot of the projects were super easy, and we finished them in less than a class period. For example, the blinking lights was pretty easy, and then as we went through the semester, the projects got harder. The last project we completed took a bunch more effort, but it was also our final project and we had to do a presentation on it. As far as the final project, we were told to pick our own project. My group and I decided to find something that’s not simple like plug in a light and turn it on with a button. Instead, we found an automatic watering device online that waters plants automatically, but the code was a bit buggy. And the class didn’t like to teach us to code with what we already know. It was more, here’s how you wire stuff, but we had a bunch of trouble with debugging the code. Debugging the code was hardest part about the project. The presentations are pretty easy, it was two to three minutes per group, because we have a bunch of groups. And you just went up there, and you’re like, hey, automatic watering system. Here’s a video of how it works.

Lauren’s Quotes #7

[88-89; 128-134] In addition to coursework, I am an undergraduate researcher working with a professor who studies Nano-materials. The Professor is like my boss, I guess. He’s a dude who runs the whole lab, and he tells us like, hey, we’re going to work on this project, or we’re going to work on that project. But he was one of the people who went up to the national lab to do the measurements. In general, he’s the one that knows most of what he’s doing at the lab, because he’s actually a doctor. He’s actually got a doctorate. So yeah, he knows a bunch of stuff about magnetism and Nano-materials.

[96-103; 112-125] When I first started on the project, I read textbooks to try and understand what magnetism is and stuff, but since then, I’ve been working in the lab more, because the professor let me know that I understood the material good enough. Most of my role as a research assistant involves running simulations on my computer, just part of why getting a new computer was really great. Lately, I’ve been using a program called Riffle 1D that takes reflectometry data. We’re doing neutron scattering, so we’re bouncing a neutron off of a sample, and then seeing what it looks like on the other side. And that’ll get measurements from the depth of it and how far apart the things are on the sample. So, once we get the data from the reflectometry, we put it into Riffle 1D, and then we have a code that says which things will have a layer of silicon and then a layer of gadolinium and a layer of other elements. And eventually we’ll it with air at the very end. Riffle 1D does is it changes the parameters for the thing, so we’ll be like, hey, we think the silicon is an instrum tall. And then Riffle 1D will be like, hey, to make it match the reflectometry data, the silicon got to be like two instrums tall. But if what we put in originally doesn’t work with the data at all, I go through and I change it to try and see if I can get it to work at all. Yeah.

[431-433; 435-439] This research opportunity led to me receiving an internship offer to work at the national lab. The professor I work with in the lab mentioned how there was an internship at the national lab we collaborate with, the place he did the measurements, for experiments. He encouraged me to apply for the internship. I said, okay, I’ll do that. And so, I applied for it. And I got the job, the internship, the job, I’m going to be working on the same project that I’m doing here. So, I’m going to be doing it at the National lab, so I’ll be able to do some actual measurements, and not just do stuff on the computer.
