Ulises Hernández

PhD Student

I'm a graduate student in the Ecology and Evolutionary Biology program. I have a BS in Biophysics, and a MSc in Mathematical modeling. I am interested in studying the structure and properties of the genotype-phenotype map of biological systems and how these properties shape the outcomes of evolutionary processes. Such properties include robustness, modularity and plasticity. Currently, I'm working on understanding how the constant appearance of mutations affects populations over time and whether epistasis patterns, compatible with empirical data, can decrease the degradation of a population and thus decrease its extinction risk.
