Shannon BarbarekShannon is an undergraduate currently working on cricket immune assays.

Ruben Martin-Blazquez. Ruben is a postdoctoral research associate co-advised with Prof. Sydney Cameron and based at University of Illinois Urbana-Champaign. He works on how the gene expression of various bumble bee species is affected by exposure to  pesticides and parasites. 

Austin Calhoun. Austin is an MS student who is working on understanding ecological impacts on bumblebee health. As an undergraduate he worked on bumblebee-trypanosome interactions.​​
