Nick is a behavioral ecologist that studies infectious diseases. In general, he is interested in spiders, flies, and their parasites, though his students have taken the lab's research in countless more directions. He also spends much time watching monster movies, reading sword & sorcery paperbacks, juggling, and listening to heavy metal.

Steven Cassidy

PhD Candidate

stevencassidy [at] ufl.edu

Steven is interested in how behavior can influence species interactions. He completed his B.S. in Ecology and Evolution at the University of Pittsburgh studying plant ecology. As an undergrad, Steven studied mutualism disruption in understory plants, and then worked as a lab technician studying how herbivory impacts the evolution of the plant root microbiome. He is currently studying the the causes and consequences of polydomy in the African social spider Stegodyphus dumicola.

Eric Trotman

PhD Candidate

email: eric.trotman [at] ufl.edu

Eric is a recent graduate from the University of Florida, where he earned his B.S. in Wildlife Ecology and Conservation. During undergrad, through the Doris Duke Conservation Scholars Program, he studied how habitat composition affects the provisioning rate of the Southeastern American kestrel. Eric also partnered with the San Diego Zoo Recovery Ecology team on their reintroduction study of the mountain yellow-legged frog, focusing on how early life history events may affect survival in the wild. During his Ph.D., Eric plans to study how multi-host parasites affect the behavior of intermediate hosts using a One Health framework.

Katie Van Havel

MSc Student

email: kathryn.vanhavel [at] ufl.edu

Katie received her undergraduate degree from the United States Air Force Academy (USAFA), where she majored in biology and received her commission to the United States Air Force as an Intelligence officer. She is on scholarship to receive her masters degree to support a future teaching role at USAFA. Katie's research will focus on wolf spiders behavioral responses to biotic and abiotic stressors. She is an avid bookworm and flipped over too many rocks looking for bugs as a kid.

Anngelyk La Luz Maldonado

PhD Student

email: laluzmalanngelyk [at] ufl.edu

Anngelyk is a recent graduate from the University of Tampa, where she earned her B.S. In Marine Science-Biology. As an undergrad student, she studied the relationship between Macrocheles muscadomesticae mites and their fly host, as well as molecular and morphological identification of mites.

Tim Colston, PhD

Assistant Professor

University of Puerto Rico, Mayagüez

Website

Tim is a herpetologist by training, but his research integrates biogeography, evolutionary ecology, and host-microbiome interactions. We are currently collaborating on a project focusing on venom evolution and venom-associated microbiomes in social spiders.

Initiative for Venom Associated Microbes and Parasites (iVAMP)

Website

iVAMP is a collaborative, open-source group of researchers worldwide of all career stages and types with the shared interest to expand the reach of each other’s work as well as the direction of the field of venom microbiomics.
