Join the Sharp Lab

The lab is an inclusive and safe space. Members of under-represented groups are encouraged to apply. Science is for Everyone!

The lab can potentially take on graduate students through the following graduate training programs:

Genetics Graduate Training Program

Ecology and Evolutionary Biology Program

Cell and Molecular Biology Graduate Program (CMB)

Integrative Biology Graduate Program

Nathaniel Sharp

Position title: Assistant Professor

Nathaniel earned his PhD in Ecology and Evolutionary Biology at the University of Toronto, and trained as a postdoc at the University of British Columbia. He is broadly interested in evolutionary genetics, and particularly the causes and consequences of mutation.

Denise Smith

Position title: Research Specialist

Denise earned a B.S. degree in biology (UW-La Crosse) and a master’s degree in Plant Pathology (UW-Madison). She has worked with fungal and viral plant pathogens of many plant species, but predominantly pathogens of trees. She is interested in evolution of fungal resistance to fungicides and how fungi evolve to maintain pathogenicity. In her spare time, Denise likes to garden, hike, and cross-country ski.

Rob Melde

Position title: PhD Student

Rob is A PhD student in the Integrative Biology program who is interested in investigating the roles that sex and recombination play in the mutation rate and spectrum. He has a background in mutation accumulation studies as well as other experimental evolution in C. elegans. He previously studied under the guidance of Dr. Vaishali Katju and Dr. Ulfar Bergthorsson at Texas A&M University where he earned a B.S. in Biochemistry and Genetics.

Jacob Fredette-Roman

Position title: PhD Student

Jacob is a PhD student in the Integrative Biology program who is interested in studying mechanisms that influence the mutation rate and spectrum of S. cerevisiae. He has a background in evolutionary biology and ecology, having worked with Dr. Michael Angilletta at Arizona State University to investigate genomic signatures of thermal adaptation in Drosophila.

Dannie Yin

Position title: PhD Student

Dannie is a PhD student in the Cellular and Molecular Biology program who is interested in studying the genetic events and mutational mechanisms of the fungal pathogen Candida albicans. She has a background in bioinformatics and microbiology, having previously worked with Dr. Schroeder to advance an expression database of Arabidopsis thaliana and with Dr. Bennett to investigate how aneuploidy in C. albicans affects colony color phenotypes on CHROMagar.

Former graduate students:

Kevin Bao. Defended Aug. 2025. Kevin is now a biology teacher at the Princeton International School of Mathematics and Science.
