Emma Gonzalez

Graduate Student

Emma's work supports our group's challenge to understand the physics inside living cells. Our approach is to model the dynamics of a confined polydisperse suspension – a model cell – via non-equilibrium statistical mechanics and low-Reynolds number hydrodynamics theory, which is leveraged in our Confined Stokesian Dynamics algorithm. Her goal is to develop hydrodynamic theory that will allow us to model non-equilibrium physical processes present in the cell milieu.

Brian K. Ryu

Graduate Student

Brian is studying time-dependent thermodynamic phase behavior of colloidal materials. By dynamically controlling states by tuning interparticle potentials and executing quench-anneal protocols, he envisions that a wide range of new materials can be created. When he is not researching and practicing colloid physics, Brian researches and practices various ways to cook meat, hoping to be a connoisseur of meat one day.

Alp M. Sunol

Graduate Student

Alp develops physics-based computational models to study how colloidal scale interactions at different biological conditions affect spatial organization and transport dynamics of molecules inside cells.  When not researching how physics at the microscopic level impacts cellular fitness, he enjoys other forms of fitness such as the gym, pickup soccer and basketball, and long walks on the beach.

Jen Hofmann

Graduate Student

Jen's research focuses on how colloidal-scale physics inform and orchestrate biological processes inside of cells. In particular, she's interested in coarse-graining macromolecular interactions for increased biofidelity of dynamic colloidal simulations, with which we can probe biological processes at long time-scales while maintaining spatial resolution. Outside of lab, she loves cooking and baking new things, watching soccer, and hiking with her dog!

Theo Yang

Graduate Student

Theo is a PhD student working jointly with Professors Roseanna Zia in Chemical Engineering and Dan Jarosz in the School of Medicine. He is interested in the biophysical factors that underlie protein aggregation in eukaryotic cells. Specifically, he is interested in developing colloidal simulations and experimental methods for understanding how the phase behavior of protein condensates at long biological time scales informs cellular stress adaptation and the development of prions. Outside of lab, Theo likes playing soccer and reading sci-fi.

Nomi

Dog-toral Student

Nomi is in her second year as the Zia Lab's resident pup -- she enjoys learning new tricks, playing with her friends, and anything that gets her thinking! She's especially interested in studying the fluid mechanics of dog lapping (Gart et al., PNAS, 2015) and the genetics of dog coat coloration (Saif et al., Adv Life Sci, 2020).
