Grad Group Affiliations:
Population Biology
Integrated Genetics and Genomics
My research interests focus primarily on population genetics and molecular evolution in the Drosophila model. We use genomic approaches to investigate the forces affecting the distribution of genomic variation and to generate hypotheses on the biological traits influenced by directional selection.

Postdoc Researcher



Julie Cridland
Email: jmcridland at ucdavis dot edu
Julie is primarily working on bee genomics in the Ramírez lab at University of California Davis. However, she still loves flies.







Didem Sarikaya

Didem is an evolutionary developmental biologist who spends a lot of time wondering about the genes/processes that determine sizes of animals and organs. She is studying population-level variants of growth-regulating genes, and how they impact growth and adult health.






Graduate Students


Colin Contino

Colin is interested in studying how spatially varying selection shapes genome and expression variation in Drosophila populations.





Lab Manager

HSHayley Sheehy
Email:hksheehy at ucdavis dot edu
Hayley is our lab manager. She participates in pretty much every research direction in the lab. She also supervises all fly stock maintenance (and we sure have lots of stocks!).
