My research integrates comparative anatomy, morphometrics, phylogenetics, and biostatistics to reconstruct the ecology and evolution of fossil mammals. I focus on the study of mammals that lived 30 to 5 million years ago. These mammals have living relatives so I often study the morphology of modern mammals to understand the taxonomic affinities and phylogenetic relationships of fossil mammals and help resolve patterns of diversity through time. I also use comparative anatomy and morphometrics to infer the ecology (such as diet, locomotion, and body mass) of fossils mammals.

My research focuses on the evolution of animal behavior. I am most interested in sexual selection, differences in reproduction caused by heritable differences in the ability to reproduce. I use insects, including crickets and flies, as my study subjects.

My research aims to understand how DNA damage is repaired in eukaryotic cells. Loss of efficient DNA damage repair causes accumulation of mutations which is a hallmark of cancer cells. I am using yeast for these studies which is a great eukaryotic model system.


Dr. Tiffiny Rye-McCurdy

Lecturer
Science & Engineering Building, Room 210B

I earned my Bachelor of Arts degree in ACS-Certified Biochemistry from Ohio Wesleyan University and my Ph.D. in Biochemistry from The Ohio State Biochemistry Program. I have completed five years of research as a graduate student and one year of research as a postdoctoral researcher in the Musier-Forsyth laboratory at The Ohio State University. My dissertation focused on the nucleic acid chaperone activity of retroviral Gag proteins during virion assembly. Currently, as a part-time postdoctoral researcher I am studying the mechanisms of genomic RNA packaging within the retroviruses Rous sarcoma virus and HIV-1.

My research explores the factors that regulate arthropod abundance and distribution, for both pests and beneficial species, across agricultural, natural, and urban landscapes. Across these systems, my goal is to explore how changes in habitat quality influence the sustainability of ecosystem services. I use a variety of methodological approaches, including manipulative field experiments, landscape analyses, simulations, ecoinformatics, and molecular approaches, to tackle ecological questions related to this goal.
