Kristin Duffield. ​Kristin is a PhD candidate studying life history theory in decorated crickets. She investigates the intrinsic state and the environmental contexts for male cricket terminal investment. Kristin is a co-advised student with Prof. Scott Sakaluk​. 
Madeline Hallahan. Madeline is an ISU Biology Education major and is working on the bumblebee system. She is the recipient of a prestigious Noyce Scholarship.

Kylie Hampton. ​Kylie is a MS student studying reproduction and immunity in decorated crickets. Previously, Kylie volunteered in the lab after graduating from ISU in 2016. Kylie is a co-advised student with Prof. Scott Sakaluk​.

Rachel Mandes. Rachel is an ISU undergraduate who is studying the interactions between the bumblebee immune response and beneficial bumblebee microbes.

Logan Sauers. ​Logan is a MS student at ISU studying the interactions between bumblebees and their beneficial gut microbes.
Kerrigan TobinKerrigan is a 2nd year MS student investigating how shifting temperatures influence immune investment and infection outcomes in a bumblebee trypanosome parasite system​. 

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

Past students and members

Mitchell Czerwinski. Mitchell worked as an undergraduate researcher on coinfection dynamics in our bumblebee and trypanosome system, and then carried out his senior thesis on interactions between pesticide exposure and immunity. Mitchell graduated in 2016. 

Marc Ashford. Marc was an ISU undergraduate and an LS-AMP mentee working on a collaborative endeavour taking a comparative look at immune responses across Hymenoptera.​ Marc graduated in 2016 and is now pursuing graduate school.

Ellie Hart. Ellie was an ISU undergraduate student. She worked in the group with bee care and maintenance, and assisting in projects on bumblebees and their parasites. Ellie graduated successfully in 2016.

Adam Frank. Adam was an ISU undergraduate who quantified infection loads as part of a project on coinfection dynamics in bumblebees. ​Adam graduated in 2016.


Aline Fauser-Misslin. ​Aline was a PhD student based at the University of Bern. She investigated how both pesticides and parasites influence crucial colony level and individual traits in bumblebees. ​​Aline graduated in 2014!

Steffanie Cain. Steffanie was an ISU undergraduate student working to understand how perception of mating possibilities influences immune investment of decorated crickets (Gryllodes sigillatus).​​ She graduated from ISU in 2014!
Joe Oremus. Joe was an ISU undergraduate student studying Aedes mosquito immunity. He focused on temporal dynamics of immunity following a standard immune challenge.
Michelle Alvarez. Michelle was an Agriculture major undergraduate and an LS-AMP mentee. She was involved in a project on temproal dynamics of coinfection in the bumblebee system. ​Michelle graduated from ISU in 2015!
Christina Jester. Christina was an ISU undergraduate student in Biology education. She worked in the group for over a year and a half helping with bee care and maintenance, and assisting in projects on bumblebees and their parasites. She really loves bees!​ Christina graduated in Biology Education in 2016!
