I’m a faculty member in the Department of Biology at Fairfield University. My research examines major evolutionary shifts in plant photosynthetic metabolism — particularly C4 photosynthesis and Crassulacean acid metabolism (CAM) — and uses these shifts as general models for how complex traits evolve. My approach spans scales, from single-cell/single-nuclei sequencing of individual species to developing new phylogenomic and comparative methods. See current projects and publications for more.

news

Apr 20, 2026 The Plant Resilience Institue at Michigan State awarded a seed grant to me and VanBuren Lab PhD candidate Jenny Schuster. Our project “Defining transcriptional cell states in desiccation tolerant plants with spatial RNAseq” will leverage a new 10X Visium machine at the RTSF Genomics Core to integrate spatial RNAseq into our single cell research on desiccation tolerant plants.
Dec 02, 2025 I accepted a position to join the Biology Department at Fairfield University next fall as an assistant professor!.
Aug 01, 2024 “Convergent evolution of desiccation tolerance in grasses” (Marks, Pas, Schuster, Gilman & VanBuren) published in Nature Plants.
Jan 01, 2024 “Predicting photosynthetic pathway from anatomy using machine learning” (Gilman, Heyduk, Maya-Lastra, Hancock & Edwards) published in New Phytologist.
