Rohan Mehta, Ph.D.

Assistant Professor, Biology
Department of Biology

Dr. Rohan Mehta is an evolutionary biologist and population geneticist who uses mathematical models to study the fundamental rules of life and how different living systems interact. He has worked on organisms from the tiny (how different genes in Staphylococcus aureus evolve with each other) to the human (how human behavior affects the spread of disease and vice versa) to the entirely theoretical (how cooperation between individuals can evolve).

Dr. Mehta earned his Ph.D. in 2019 from Stanford University, where his thesis was titled “Mathematical Modeling of Biological and Cultural Traits”. He then worked for five years as a postdoctoral researcher at Emory University before joining the faculty at Elmhurst University in 2023, with a focus on bioinformatics and computational biology.
