Curriulum vitae 

Areas of specialization: Insect conservation & ecology, molecular systematics and biodiversity informatics

Primary interests:

Dr. Gwiazdowski is interested in biodiversity at the species level, particularly ways to discover, identify and conserve what we consider “species”. Rodger’s research focuses on insects, where he explores primary questions about evolution, diversity, ecology and conservation, using molecular systematics, bioinformatics, ecology, and animal husbandry.

Prior to his graduate work, Rodger worked in several zoological institutions (Bronx Zoo, NY Aquarium, and the Liberty Science Center). Rodger completed his Ph.D. in Evolutionary Biology & Entomology (joint degree) at UMass Amherst in 2011, where he found extraordinary cryptic species-diversity in one widespread North American pest insect that’s been “well known” for over 150 years; concurrently, he developed captive-rearing techniques for rare tiger beetles. He then went to Canada as a post-doctoral fellow with the Biodiversity Institute of Ontario, where he developed high-throughput DNA reference libraries for rapid insect identification, and combating seafood fraud. He currently consults on conservation projects with Federal and state governments, and serves as Principal Investigator of the Puritan Tiger Beetle Recovery Project, with the Silvio O. Conte National Wildlife Refuge.

Current Projects:

– Puritan tiger beetle ecology, and population dynamics in the Connecticut River (This work was a cover story of the Science Times: https://www.nytimes.com/2018/12/04/science/puritan-tiger-beetles-vicious-predators-may-soon-hunt-again.html)

– Phylogeographic diversity, and life history of the Cobblestone Tiger Beetle

– Constructing the first life table for a North American tiger beetle
