Nicole Gerardo
Principal Investigator

I am interested in how ecological and evolutionary dynamics shape species interactions. We utilize a range of systems in our research, from fungal pathogens found in ant gardens to nematodes and bacteria that protect them from environmental stress.

German Research Foundation Postdoctoral Fellow

I am interested on the chemical ecology of symbiotic interactions. Currently, I am focusing on the chemistry of host-parasite specificity.

Scott Villa
NIH-FIRST Postdoctoral Fellow

I am interested in how symbiotic interactions influence the mating behavior and reproductive compatibility of their hosts.

Anna Zelaya
Post-doctoral Fellow

Working with Chris Beck on NSF-Funded Bean Beetle Microbiome Research Project

I am interested in how environmental factors affect microbial diversity and function. I am also interested in STEM education and the factors that promote or inhibit student success in STEM.

Erica Harris
NSF-GRFP Graduate Student

Co-advisor: Jaap de Roode

I am interested in how environmental factors mediate host-parasite interactions and uses monarch butterflies to study how host diet and gut microbial communities mediate disease resistance.

NSF-GRFP Graduate Student

Co-advisor: Levi Morran

How do symbioses evolve? Experimental evolution with C. elegans and B. subtilis.

Sandra Mendiola
NSF-GRFP Graduate Student

Co-advisor: Dave Civitello

The use of symbionts to disrupt the transmission of vector-borne pathogens.

Kayla Stoy
NSF-GRFP Graduate Student

Co-advisor: Levi Morran

Role of horizontal transmission, sex, and gene flow on the evolution and maintenance of mutualisms. Squash bugs and Burkholderia. C. elegans.

Jason Chen
Graduate Student

Co-advisor: Nic Vega

Microbial interactions, evolution and maintenance of symbioses, insect ecology.

Jacoby Robinson
Rotating Graduate Student

I am interested in host-parasite interactions and dynamics spanning the scale from organismal to population levels.
