Trevor Krabbenhoft, Assistant Professor

We study fish genome evolution and the origins and maintenance of biodiversity. I am particularly interested how polyploidy (whole genome duplications) contribute to phenotypic and ecological diversity in fishes such as suckers (Catostomidae) and ciscoes (Salmonidae).

Dr. Daniel (Dan) MacGuigan, NSF Postdoctoral Research Fellow in Biology

Dan studies fish evolutionary genomics, hybridization, and speciation. Read more about his work on his website.

Dr. Levi Gray, Postdoctoral Researcher

Levi studies speciation and phylogenetics in a wide variety of organisms.

Nathan Backenstose, Dean's Graduate Fellow and Ph.D. Candidate

Nate is studying the evolution of the Great Lakes cisco (Coregonus spp.) species flock.

Hannah Waterman, Schomburg Graduate Fellow and Ph.D. Candidate

Hannah is studying the evolution of DNA methylation following whole genome duplication in fishes. She is also interested in how DNA methylation contributes to sex determination in fishes.

Kimberly Louisor, Schomburg Graduate Fellow and Ph.D. Student

Kimberly is studying the genomic mechanics behind aging in Bigmouth Buffalo (Ictiobus cyprinellus) and the evolution of aging in catostomids. She also works with the lab on invasive species research in Lake Erie and the Niagara River.

  Christopher Osborne, Ph.D. Student

Christopher is studying variation in thiaminase tolerance in lake charr (Salvelinus namaycush) populations using pan-genomics. He is also investigating how hatchery environments may alter the epigenetic characteristics of lake charr used for restoration stocking efforts in the Laurentian Great Lakes.

Sarah Chang, Research Assistant

Sarah is interested in the use of genomics to investigate evolutionary applications to fish conservation and adaptation to climate change.

Brian Foote, M.S. Student

Brian is currently studying the invasion dynamics and genomes of grass carp (Ctenopharyngodon idella) in Lake Erie. He is also our boat captain on Lake Erie.

Pia Schwarz, M.S. Student

Pia is studying the ecology and evolutionary dynamics of a hybrid swarm of tessellated darters, Etheostoma olmstedi. She is also an excellent tennis player at University at Buffalo, having recently been named to the MAC 1st team!

Katie is now a PhD Student in the Bernal Lab at Auburn University.

Jessie Pelosi, Formerly an undergraduate honors student at Univ. Buffalo.

Jessie did his undergraduate research on octocoral bleaching and systematics (M. Coffroth and H. Lasker labs).

He is currently a Grinter Fellow and PhD Candidate at the University of Florida, working on comparative and population genomics of ferns in the Sessa and Barabazuk labs.
