Sloan Scholar Spotlight: Gavin Gonzales


Gavin Gonzales is a rising third-year doctoral student in biomedical engineering at Duke University, where his academic career has evolved from theoretical ideas to applied research—a journey that reflects his passion for both learning and doing.

Gavin studied physics at the University of New Mexico, researching quantum dots and how they absorb and emit light. His work as an undergrad taught him that “research is about finding what makes something work, and then studying how that implication goes further.” He enjoyed physics and was interested in his research, but he couldn’t apply it to anything outside the lab.

His first opportunity to see how research can be taken further was at Duke during a summer research program through Maximizing Access to Research Careers (funded by the National Institutes of Health). There, he worked with bioengineering and biomaterials for the first time, and he realized the appeal of applied research. Then, the summer before he started his PhD, he worked at Draper Laboratory on prosthetic heart valves for children.

Both research experiences exposed him to the power of applied research and collaboration. The experience at Draper, in particular, made him realize his passion for bioengineering and the problems it solves, specifically at the intersection of academia, industry, and research. At Draper, he participated in collaborations between Draper researchers and professors at other universities, giving him insight into how industry collaborates with academia.

Now at Duke, Gavin is researching the design of knee-joint lubricants, investigating how they bind to cartilage and can reduce the amount of wear on the joint from daily activities. He is also designing a joint-model system to mimic the body’s repeated motion on cartilage.

For Gavin, this research is more than broadly practical: he worked at a physical therapy clinic throughout high school, and he was impressed by the therapies that improved people’s quality of life. Now as an adult, Gavin is passionate about spending time outdoors, hiking, running, and his own health in general. In bioengineering, his passion for knowledge can combine with real-world applications.

While Gavin was inspired by his time in private industry, he is just as passionate about staying in academia, wanting to become a professor after he graduates. He’s seen applied research from both sides, and he’s looking forward to collaborating with other researchers and other industries. But, importantly, he also wants to mentor students.

His own experiences with mentors have motivated him to expose as many people to good mentors as he can. Not only has Gavin been a one-on-one mentor, he also works on programs that bring mentoring to communities. Most recently, he volunteered in a mentoring program with the Society for Hispanic Professional Engineers. He’s also spoken to middle and high school classrooms, highlighting why he got into research and what he finds fun about it.

“Being a mentor has made me realize that in order to help someone, you need to understand what they are looking for. Now I know I need to communicate my expectations to my mentors so they can help me. Two-way communication is very important.” When he has struggled with coursework in the past, he had a similar approach: reach out to peers with your challenges. Usually, each person is struggling in a specific way, and your classmate may have an understanding you don’t, and visa versa.

Just as Gavin seeks to apply what he learns and share that knowledge with others, he recommends other Sloan Scholars do the same. “Be ambitious, figure out your goals, and share them with as many people as you can. Make connections, advocate for yourself, and know that you can help yourself develop the most.” For him, being a Sloan Scholar (and now a member of the SloanConnect Student Advisory Committee) means having access to professional development, mentors, and friends—”a community away from home.”

Tell me a little about what brought you to Duke.

One of my personal goals was to pursue a Ph.D., but I wasn’t sure exactly what within mechanical engineering I wanted to study or what school I wanted to attend. Therefore, I researched various schools and mechanical engineering programs; Duke was one of the schools that I decided to apply to. I was interested in what the professors were doing, specifically my adviser, Dr. Aquino. I was excited to learn more about computational mechanics, data-driven modeling, and inverse problems.

How has the Sloan Scholarship helped you?

One of the main reasons I liked the Sloan Scholarship—although I didn’t get to take full advantage of this resource—was the Early Start program. When I was transitioning from high school to undergrad, I was a part of an undergraduate early-start program at Tuskegee University. This program was beneficial because I got to know a few people before school started, take some classes, and get acclimated to Tuskegee. I liked that the Sloan Scholarship has a somewhat similar program. I wasn’t able to go because I had an internship already lined up, but I did get to participate in some events virtually. It was nice to get some tips and tricks on how to do well in graduate school. There were a lot of awesome opportunities from attending those seminars online.

Tell me about your research.

My research is related to physics-based modeling and machine learning. Over the summer, I completed a small project as an introduction to using machine learning for sound identification. When I formally start my research, I’ll use machine learning with ultrasound scans to diagnose patients’ vascular health as healthy or unhealthy. Physics-based modeling will provide more in-depth understanding of the machine learning model parameters.

What are some significant experiences you had as a result of the program?

Every semester we meet with the Graduate Sloan Intern in small groups to support and uplift one another. Additionally, The Graduate School hosts plenty of events for us. We have various lunches where different speakers talk to us about their graduate experience and give us advice. Those events have made my experience as a graduate student better.

What do you like about Duke so far?

On campus, my favorite thing is all the study areas. For example, The Edge is awesome; there are white boards and study rooms everywhere. The whole campus is very conducive to studying.

What are some challenges you’ve encountered and how have you overcome them?

My biggest challenge right now is classes. I found it hard to transition from undergrad to graduate classes. For example, I didn’t take linear algebra in undergrad and now that I’m in a computational mechanics lab, linear algebra is very important. It was difficult to come in without that background. To overcome this challenge, I went to Math Help Room regularly, formed study groups, and talked to students with more Linear Algebra experience.

Additionally, Sloan has been a great resource, and I’m a part of a newer group called Sisters in STEM. Dean [Jacqueline] Looney in The Graduate School is one of the program leaders, and we get together once a month for conversation. We talk about struggles we are having in graduate school and outside of graduate school, including finding work-life balance.

Tell me a little about what brought you to Duke.

A lot of the things that make Duke unique to me is what brought me here. For example, I have a family. I have a wife and a small kid, so when I came in for interviews one of the things that made Duke unique was that they offered to accommodate for my family and have them come over and see the campus themselves. All of that extra effort that went in to accommodate for my family is what made me feel welcome, and what made Duke different from other schools.  

How has the Sloan Scholarship helped you?  

In addition to the financial resources, which are great, Sloan has given me opportunities to not only work with people in different disciplines, but it also gave me the opportunity to acclimate and get used to the Ph.D. experience ahead of time. I came in over the summer and we had our Early Start program, which really helped me find who I wanted to work with in my own department, as well as other things. Sloan also got us used to all of the resources offered by not only The Graduate School, but also Duke in general. Having that time to come in early gave me time to learn all of those things so I wouldn’t have to learn about them while I’m trying to work on my academia at the same time.   

Tell me about your research.

I work in the Department of Computer Science, where I specialize in the intersection between data privacy and algorithmic fairness. With the general idea being that we have methods to protect data privacy when doing statistics methods, and we have some algorithms that are considered fair. I study what happens when you use privacyprotected data in a fair setting. Does the algorithm remain fair? Do the fairness conditions break down? My job is to make sure that this composes well.  

What are some significant experiences that you have had as a result of the Sloan Scholars program? 

I’ve really enjoyed some of the experiences we’ve had as Sloan Scholars to interact with incoming students. The hardest part about graduate school so far has been applying, because you go through the application process and you have no idea how you’re supposed to present yourself, what you’re getting into, or what they want to see. Especially when you write the personal statement, it can be very difficult. So having a chance to look at all these students who are now trying to apply to graduate school, give them advice, help them and tell them what graduate school is all about is great.  

What do you enjoy most about Duke so far?

I really enjoy the community and how well it receives divergent ideas. At least in my department, I’ll go into a room and talk with a bunch of other graduate students and we’ll have different ideas on how to approach the same topics. While we all might have some disagreements on whether some things are reasonable, we are all willing to listen to each other and have those kinds of conversations.  

When I applied, I feared that the research environment would be so competitive that I wouldn’t be able to talk to other students about my work without them stealing my work. The fact that I can turn around and talk to other students in my office and say, “Hey do you guys think this is a good idea or am I just going nuts?” without any fear of repercussions or them thinking badly of me shows that the environment is in such an accepting, healthy state.   

What are some of the challenges you have encountered and how have you overcome them? 

Having a family, especially as a graduate student, makes you significantly different from most people. It makes it hard to break into friend groups and have a social experience, but Duke has a couple of programs for that. The GradParents support groups have been very helpful with finding other graduate students who are parents, and find those people that you can more directly relate to. If I were to talk to my officemates about children, their eyes would glaze over because they would have no idea what I’m talking about. Finding other students through the parent support groups has allowed me to have those conversations, and that’s something that I never really expected to find.
