Graduate student in the biological sciences PhD program at Purdue University. B. S. in microbiology from Purdue University. Current work is in structural biology of bacterial microcompartments. I have previous experiences in various disciplines in biology, including molecular biology focused cancer research, ecology and evolution, physiology, immunology, and agricultural applications of genetics.

I maintain a strong interest in ecological research and exploring the biodiversity especially in my local county (Tippecanoe, Indiana). I am most active as a birder, and store all my bird data with the eBird project: https://ebird.org/profile/NzYwMTkw/US. Some of these sightings which have photo vouchers are also recorded on this site. I also contribute noteworthy or interesting sightings to BugGuide (username mothmadness). I am currently trying to integrate all my photographic records into iNaturalist. I am working to document all my records in a personal database with more detailed documentation - feel free to reach out via DM if you think this data would be useful for your project.

My primary expertise and interests are in birds, lepidoptera, and odonata. I identify birds in the United States and lepidoptera/odonata usually in Indiana or within the surrounding areas.

Favorite taxa: Scissor-tailed Flycatcher, Lark Sparrow, Killdeer, Elegant Trogon, Common Nighthawk, Eastern Giant Swallowtail, Nessus Sphinx, Virginia Ctenucha, Petrophila moths, Eastern Red Damsel, Blue-ringed Dancer, Eastern Forktail, Azure damsel, Cobra Clubtail, Prince Baskettail.
