Anthony Says, "Later, Gator!"

Gator!This week, we bid a fond farewell to Ph.D. candidate Anthony Auletta, as he heads down to Gainesville, FL to begin his new position as Lecturer of Insect Biology at the University of Florida Department of Entomology & Nematology. As a member of the teaching faculty at UF, Anthony will develop and teach a variety of entomology courses, as well as advise undergraduate students and coordinate CUREs (course-based undergraduate research experiences). It is a perfect fit for Anthony, who is passionate about entomology and undergraduate education, and we wish him the very best in Florida!

Anthony will be back to visit Minnesota next month, to formally defend his Ph.D. dissertation.

Anthony presents at SICB 2019


SICBPh.D. Candidate Anthony Auletta is kicking off the new year in sunny Tampa, FL, at the 2019 Annual Meeting of the Society for Intregrative & Comparative Biology (SICB). The meeting will take place in the Tampa Convention Center from January 3-7th. If you'll be in attendance, please come check out Anthony's poster, which details the latest and greatest research he's done as part of his doctoral dissertation:

Auletta A, Mesce KA. 2019. An examination of biogenic amines in nervous system of the scorpion Centruroides sculpturatus (Scorpiones: Buthidae) provides insight into the evolution of neuromodulatory systems in the Arthropoda. 

And, of course, from all of us here in the Mesce Lab, have a safe, happy, and productive new year!! We look forward to all of the wonderful things to come in 2019!

New Faces in the Mesce Lab!

We have two new faces joining us in the Mesce lab this fall! 

Emiliya (Emma) Bayko is a new undergraduate researcher in the lab, who will be working with us on our ongoing project to uncover the mechanisms of recovery following nerve cord injury in the leech. Emma comes to us from Metropolitan State University, where she has previously worked with Asst. Prof. Cindy Harley (former postdoctoral fellow in the lab)! We look forward to working with Emma this semester, as well as our continued collaboration with Cindy on this project!

Also joining us this semester is Radhika (Rads) Edpuganti. Rads is current undergraduate student in the Neuroscience program here at the U of M, and will be working with us over the next year on a variety of projects, including the leech revovery project, our arachnid neurobiology project, and the ultrasonic neuromodulation project. We are very excited to have Rads onboard!

Welcome, welcome, Emma and Rads!
