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.

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.

Anngelyk La Luz Maldonado
PhD Student
email: laluzmalanngelyk [at] ufl.edu
Anngelyk joined the lab in 2024 and studies fungal parasites of spiders with a focus on parasite manipulation of host behavior. She uses observational and experimental techniques to study the specialist araneopathogen Gibellula.

Sanjana Hegde
PhD Student
email: hegde.sanjana [at] ufl.edu
Sanjana joined the lab in 2025 and is interested in host-pathogen coevolution. She will be working on venom-associated microbes in spiders.

Kamili Henry
Undergraduate researcher working with the SPDR Collection and the effects of fungal infection on spider behavior.

Sloane Murphy
Undergraduate researcher interested in vector borne diseases and medical geography.

Devin Travers
Undergraduate researcher interested in spider behavior and ecology.

Tim Colston, PhD
Assistant Professor
University of Puerto Rico, Mayagüez
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)
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.
PDF of our first paper describing the field of venom microbiomics and introducing iVAMP.
