Assistant Professor of Biological Sciences | Principal Investigator
My research interests focus on beneficial host-microbe interactions, particularly in defensive symbioses of marine invertebrates. My lab uses molecular genetic and bioinformatic techniques to understand which genes beneficial symbionts need to chemically protect their host from infection and predation.

Andrew is conducting independent research on the Type I Polyketide Synthase (T1-PKS) of squid egg symbiont, Leisingera sp. ANG1. He also participated in the 2024 Summer Science Research Program, looking at symbiont competition in the squid eggs.

Julien and Sophia optimized a method to make hydrogel spheres to mimic squid eggs. This method allows us to encapsulate different squid egg bacteria and see how they interact in a host-like environment.
Andrew and Doyi investigated competition between symbionts in squid eggs by injecting different strains into the eggs and monitoring their growth over egg development.

Natalia's independent research examines the keratinase activity of Bacillus spp. feather-degrading bacteria. She worked with Dr. Suria to set up the lab'sMinION sequencer and sequenced the genomes of bacteria with strong keratinase activity.
Natalia is pursuing a PhD at The Ohio State University.
