About Rahul Roy

Rahul Roy is a plant biologist focusing on the mechanisms of nectar production in flowering plants and plant root movements. He teaches Foundations of Biology, Environmental Biology, Plant Biology and Research Proposal writing courses at St. Kate's. His lab research (setup in 2020) will focus on the analysis of colorful nectar, dissecting roles of hormones and membrane transporters in nectar production and the morphometry of plant root movement in response to touch and gravity. As a student researcher in the Roy lab you will train in microscopy, genetic, biochemical, cellular and molecular techniques to elucidate pathways that are involved in the above mentioned phenomena. Rahul has previously worked on projects funded by NASA, NSF and the USDA and mentored >10 student researchers. Students in the Roy lab will learn to ask foundational scientific questions, think critically, formulate hypothesis, design experiments, analyze data and disseminate results. When not teaching science or tinkering in the lab, Rahul gardens with his family, pretends he is on a "Chopped" episode in his kitchen, hammock camps on hiking trails and hopes for peace on the planet.
