Edmund Havener graduated with a BA in neuroscience from Pomona College in 2022, joining the KM lab in July of 2024 as a Researcher 1.   He loves mountains, rivers, forests, trees, climbing, biking, running, and reading. 

Undergraduate Assistant Lab Manager

Grace Baniukiewicz joined the lab in March 2024. She is a junior at the University of Minnesota studying biology, hoping to pursue a master's degree in nursing. Outside of academics, she enjoys rock climbing, baking, and spending time with friends and family.

Postdoctoral Scholars & Research Scientists

Prakash Devaraju trained initially as a veterinary surgeon in India.  He then switched to a neuroscience research career and obtained his Ph.D. in Neuroscience from the University of California, Riverside working with Dr. Todd Fiacco on astrocytic glutamate uptake.  In his post-doctoral research with Dr. Stanislav Zakharenko at St Jude Children’s Research Hospital, he studied hippocampus-dependent cognitive dysfunctions in mouse models of neuropsychiatric disorders.  After a brief stint as a researcher at the University of Utah, he has started as a research scientist at the University of Minnesota in February 2024.   In a joint project between the labs of Dr. Madhuvanthi Kannan and Dr. Krook-Magnuson, he will be examining cell-type specific contributions to hippocampal circuit dynamics in epilepsy.  When not busy with lab work, Prakash enjoys tamil songs, movies, jogging, yoga (only simple poses), biking, spending time with friends and family, exploring nature and out of necessity, preparing some Indian foods at home.

Jessica Froula graduated with a B.S. in Biology and Psychology from Birmingham-Southern College in May 2016 and joined the K-M lab via the Graduate Program in Neuroscience in June 2019.  She completed her thesis in April of 2024, and is currently doing a short postdoc in the lab before moving on to her next postdoc.  Her work in the lab has demonstrated that hippocampal CA1 inhibitory interneurons respond to cerebellar stimulation, and do so in a bidirectional, coordinated, manner, in-line with their functional roles.  In the process, she also examined CA1 interneuron responsiveness to objects (spoiler alert: they are!).  Some of her favorite activities outside the lab include gardening, biking, and reading books.

Graduate Students

Lauren Glassburn received a BA in Neuroscience from Vanderbilt University in May 2018 and is now pursuing a PhD through the Graduate Program in Neuroscience. She joined the KM lab in July 2020 and is looking forward to learning slice electrophysiology. When she’s not in lab, she enjoys hiking, backpacking, and hanging out with her pet bearded dragon, Beardo.  


Shayne Hastings graduated with a BA in Psychology from the University of Texas at San Antonio in 2018. She joined the KM lab in 2021 as a doctoral student in the Graduate Program in Neuroscience. Her scientific interests include neuromodulation and brain circuit physiology. Shayne enjoys cross stitch, hiking with her friends, and relaxing with her cat Mowgli.  



Peroushini Villiamma graduated with a B.A. in Neuroscience from Macalester College in 2020. She joined the KM Lab in 2024 as a doctoral student in the Molecular Pharmacology and Therapeutics program. She's excited to parse apart the communications between the cerebellum and the hippocampus during seizures. She enjoys walks, watching kdramas, and doing puzzles.
