Robert Castillo
STUDENT SPOTLIGHT
Meet Robert Castillo! Robert is a third-year Mechanical Engineering and Education Studies double major looking to get a PhD in Nuclear Engineering to become a professor. He was previously involved in the Summer Undergraduate Research Program, hosted by the Henry Samueli School of Engineering and Applied Science, and the Summer Programs for Undergraduate Research, hosted by the Undergraduate Research Centers. Currently, Robert is a member of UC LEADS and is conducting research on the Solar Methane Pyrolysis Project, specifically designed to manufacture the next generation of graphitic carbon-carbon composites, as part of the Nano Transport Research Group under the direction of Dr. Timothy S. Fisher.
1. How did you first get involved in your research project? Tell us a bit about the lab you are in and the research you are conducting!
I am a part of the Nano Transport Research Group (NTRG) under the direction of Dr. Timothy S. Fisher and I work alongside my graduate student mentor, Benjamin T. Heronimus, on the lab’s Solar Methane Pyrolysis Project specifically designed to manufacture the next generation of graphitic carbon-carbon composites! Some applications of these types of C-C composites range from providing superior thermal management within aerospace vehicles in addition to serving as a carbon-neutral option for moderating materials in the next generation of nuclear reactors. My specific focus on this project centers on testing the final composites’ mechanical properties through tensile tests and material characterization, with the hope of one day incorporating indigenous Latin American weaving practices and ion-irradiation campaigns into the scope of the work.
I first got involved in my lab during the Winter Quarter of my first year at UCLA where it honestly took a lot of trial and effort to find the right fit, based both on personal circumstances and opportunities available. I had the chance to attend one of Professor Fisher’s office hour sessions early in the quarter to discuss possible research projects, and it was just a matter of filling out the lab interest form and connecting with Ben to get started on some exciting work!
2. How would you describe your research experience at UCLA?
I think my research experience here at UCLA has been nothing short of uplifting for not only my professional self, but my personal life too. As I started out at this university, I struggled with immense bouts of imposter syndrome and doubts about whether I could keep up with the rigor that is expected at UCLA; however, as my research has become more ingrained into my daily life as a student and I’ve had the chance to meet more researchers outside of my project or NTRG as a whole, I no longer experience these feelings of inadequacy to the same degree. Not to mention, being at the forefront of graphite research reveals a lot of machines and technology you didn’t even know existed, so my experience has been “world-opening” in that regard.
3. What is your year and major?
I am a third-year Mechanical Engineering and Education Studies double major.
4. What is one piece of advice you have for other students thinking about getting involved in research?
My one piece of advice for anyone wanting to get into research is to just apply to that lab or talk to that professor that conducts work you’re interested in no matter what. When I first started out in my lab, I knew absolutely nothing about graphite, composites, or many of the concepts involved in my work. When I applied to NTRG, I had just finished taking Pre-calculus and Introductory Chemistry, with no physics or engineering courses yet on my transcript. Over the course of time in your lab, you will pick up on the flow and procedures even without the contextual classes, so there’s no need to worry!
5. Have you attended a conference before? If so, can you describe your experience on preparation, presenting, etc.?
While I have not attended a conference before, I have presented at a physical poster symposium early on in my research journey. I honestly felt that the hardest part about that event was the amount of time needed to really flesh out my poster, both in content and layout, in a way that followed every requirement listed out by the program. There were a lot of weekly meetings about a month and a half before the symposium date to make sure we had work that fit the guidelines. I think this is good though, since you know that when it is time for the actual poster or vocal presentation, you have passed the hardest part of the entire process; your knowledge and confidence about your research will naturally seep through, even if you don’t realize it in the moment
6. Have you had your work published? Can you talk about what that process was like?
Yes, I was recently included as an author on a NTRG paper publication shared with my PI and my graduate student mentor about the mechanical properties of our carbon-carbon composites. Similar to preparing for a vocal or poster presentation, there is so much preparation to be done even before you begin the actual writing part. A substantial literature review of both current and foundational studies within your field not only makes up a lot of the introductory content, but also how you guide and present your writing later on in the paper. There were a lot of meetings between Professor Fisher, Ben, and myself to establish the narrative and messages we wanted to send through this research. Writing a paper grants you the unique opportunity to combine traditional writing with the world of scientific diagrams and figures to tell your research story, an aspect to this process that I found especially rewarding. I discovered that getting the initial manuscript ready for submission was only the first hurdle, and the review process can take a lot longer than you might first assume, a couple months after your initial submission, actually. It may seem like a lot of difficult work, and it is, but there really isn’t a better feeling than seeing your name on a publication just like the ones you read for your literature review.
7. What are your future career goals?
My future career goals involve getting a Ph.D. in Nuclear Engineering to become a professor in order to intersect my passion for engineering and education. I would love to continue my research interests in nuclear moderating materials to investigate ways to make our current and future fleets of reactors safer for all communities that they reside in.
8. Please list any URC/departmental programs you are/were involved in. How has your experience been in these programs?
I was previously involved in both the SURP and SPUR programs, and I am currently a member of the UC LEADS program that has led to my future involvement in UC Berkeley’s CalNERDS summer research experience. My work in the past two summers with the SURP and SPUR programs were instrumental for honing my skills as a researcher and becoming more connected to my project; learning presentation, poster-making, and experimental design skills are key components to my resume and overall skillset as a student. UC LEADS has provided me access to a plethora of resources surrounding how to become more resilient in the lab, research ethics, and best practices to promote minority success within STEM graduate programs. As I progress through UC LEADS, I know it will be instrumental to helping me apply to graduate school and remaining funded throughout my Ph.D. journey, in addition to the continuing the wonderful connections I have made with my cohort!
9. What was the impact of undergraduate research on your career path?
My experience within undergraduate research has not only molded my intentions to become a professor one day, but also has nailed down my specific interests within the broad field of nuclear energy. Without my time in NTRG and the Solar Methane Pyrolysis project, I do not think I would have as strong of an interest in graphite and carbon-carbon composites as I do now. Through research, I found the perfect way to combine my enthusiasm for engineering and education.
