Our lab is interested in how exogenous factors and secreted immune effectors shape the ecology of gut microbiomes. Our research includes understanding the developmental ontogeny of human microbiomes and investigating gut host-microbe interactions with an invertebrate chordate model system, Ciona robusta.

Dr. Ojas Natarjan earned his PhD at Clemson in 2018 studying nutraceuticals and aging in C. elegans. Ojas will now be focusing on studying the role of secreted immune effectors, such as VCBPs in Ciona, in modulating the ecology and biology of gut microbiomes. As a postdoc, Ojas will help develop a variety of our programs, co-lead our mentorship efforts, and help steer the ship! He will also get unique opportunities to teach within USF and at St. Petersburg College.We are very lucky to have Ojas join our lab. Welcome!
Summer interns 2019: Caleb Poock from U. North Florida and Alexis Peterson, our REU student on the NSF-MCB project.
Former recent undergrads: Elliana Walster, Michael Schepps, and Julie Voelschow. Good luck to Jessica Kramarz on her mission with the Peace Corps.
Britt was supported by the NSF Graduate Research Fellowship Program. She is now a postdoc at Vanderbilt with Seth Bordenstein.
