Joaquin C. B. Nunez, Ph.D.

Ecologist and Evolutionary Biologist

Welcome to my personal website. I am a Research Associate of Evolutionary Genomics at The University of Virginia's Biology department.

My research studies how evolution shapes functional genetic variation in natural populations living in highly variable environments. I seek to build an integrative view of the role of selection in nature from single mutations to complex phenotypes. My research is conducted in the laboratory of Alan Bergland at UVA.
