Katherine Herperger
Why did you decide to pursue a graduate degree?
Since the beginning of my undergraduate studies in physics, I’ve known that I wanted to pursue a PhD. I was inspired by the PhD students around me, who were working on fascinating projects and developing the skills of independent researchers. In physics, a PhD is not only essential for a career in academia but also a significant asset in industry.
Why did you decide to study at UBC?
I initially came to UBC as a master's student. The pandemic travel restrictions had just been lifted and I was ready to live in a new city. UBC’s strong research reputation and excellent physics facilities made it an easy choice. I decided to stay for my current degree because I found an incredibly supportive PhD supervisor, Dr. Joerg Rottler.
What is it specifically, that your program offers, that attracted you?
Through my program, I’ve had the opportunity to work at the Stewart Blusson Quantum Matter Institute, a leading research centre at UBC. The interdisciplinary environment here fosters collaboration across diverse fields, and the potential for international partnerships makes the work especially exciting. As a fun bonus, a few researchers bring their dogs to the building, which is always a welcome addition to the office!
What was the best surprise about UBC or life in Vancouver?
The best surprise for me was that I met my partner here, and have made life-long friends! I feel very lucky!
What aspects of your life or career before now have best prepared you for your UBC graduate program?
During my undergraduate studies at the University of Ottawa, I participated in the co-op program, where I developed essential computational skills and gained firsthand experience leading the writing of a couple research papers. I worked alongside supportive mentors - supervisors, postdocs, and PhD students - who modeled what it means to be a kind, curious scientist. I'm grateful for their guidance and the positive example they set.
What advice do you have for new graduate students?
I would offer two pieces of advice. First, find an activity that helps you relax. For me, that’s going to the gym or taking walks along the beach. It’s time I set aside to disconnect and recharge. Second, remember that your degree is yours to shape. Don’t hesitate to advocate for what you need, and trust your ability to make decisions that are right for you.

I develop and implement genetic algorithms to optimize time-dependent processing protocols for diblock copolymers. These are polymers composed of two distinct blocks of monomers (A and B) covalently bonded into a single chain. My goal is to direct these systems toward forming an ideal lamellar phase, which is a well-ordered nanostructure that emerges from the self-assembly of the A and B domains. To model the polymer dynamics, I employ dynamical Random Phase Approximation (RPA), a mean-field theory that describes the system’s linear response to thermodynamic fluctuations and provides insight into phase behaviour and stability.
