Graduate Students
Erica Berent |
|
Sam Hinkley |
Erica graduated with a B.A. in Biology from the College of Wooster in 2021. She began the M.S. program at John Carroll in Fall 2023, and is studying maternal provisioning of alkaloid defenses in the strawberry poison frog, Oophaga pumilio, from Bocas del Toro, Panama.

Sam graduated with a B.S. in Zoology from Michigan State University in 2020. He began the M.S. program at John Carroll in Fall 2024 and has broad interests surrounding the function and physiology of chemical defenses in dendrobatid poison frogs. His thesis research will aim to study the physiological effects of alkaloid sequestration in the green and black poison frog, Dendrobates auratus in Costa Rica.

Undergraduate Students
Grace Burkin |
|
Aaron Fernando |
Grace is a senior Biology major at JCU, and she joined the lab in Fall 2023. She was awarded a 2024 Summer Undergraduate Research Fellowship (SURF) from JCU, and spent 1.5 months in Costa Rica with lab mate Jason Freisen studying poison frogs. In particular, they studied the physiological effects of alkaloid sequestration and the links between coloration and stamina in the strawberry poison frog, Oophaga pumilio. Grace has also been in charge of caring for the live poison frog colony in the Saporito Lab.

Jason FreisenJason is a senior Biology major at JCU and joined the lab in Fall 2023. He was awarded a 2024 Summer Undergraduate Research Fellowship (SURF) from JCU, and spent 1.5 months in Costa Rica with lab mate Grace Burkin studying poison frogs. In particular, they studied the physiological effects of alkaloid sequestration and the link between coloration and stamina in the strawberry poison frog, Oophaga pumilio. Jason is now working on an NSF-funded project on tricyclic alkaloid sequestration in poison frogs.
