Long-range inhibition in the healthy and epileptic hippocampus
Postdoctoral Fellow, Icahn School of Medicine, Mt. Sinai, New York City.
Esther Krook-Magnuson, Ph.D., Department of Neuroscience
Description of Graduate Research:
My research explores inhibitory neuronal circuitry, diversity, and specificity of function in healthy and epileptic rodent brains, with an emphasis on long-range projecting inhibitory neurons of the hippocampus. Techniques used in my research include: intersectional genetic and viral approaches to label highly specific neuron populations, electrophysiology including whole-cell patch clamp recordings, optogenetics in slice preparations and in vivo, stereotaxic surgery, immunohistochemistry, fluorescent confocal microscopy, and whole brain tissue clearing and imaging.

Why Did You Choose MN?
I chose Minnesota for graduate school because of the emphasis on classes during the first year and, more importantly, because of the supportive and cooperative network of students and faculty. During recruitment weekend it became abundantly clear that the students fostered a really fun, creative, and collaborative community. I was excited about the comprehensive coursework because it is important to me to be trained as a well-rounded neuroscientist with knowledge of topics in neuroscience outside the specific expertise I will develop in my thesis lab.
What Advice Would You Give to a First Year Graduate Student?
Advice #1: All the best advice I ever got was given to me at GPN student gatherings – apple picking, happy hours at Stub & Herb’s, around coffee after colloquium, at Career Facilitation Committee dinners… Ask any student any question, and they will give you their best and most honest answer as well as guide you towards all the other people who have had relevant experiences.
Advice #2: Things to consider when choosing an advisor (in my opinion) are: 1) the advisor’s mentorship style (Is it hands-on enough? Is it too hands-on? Will they commit the desired amount of time and energy to you?), 2) the day-to-day activities in the lab (Will you like sitting in front of a computer all day? Do you like having a diverse array of experiments to run, or do you like to really focus on one technique?), and 3) the lab environment (Do you enjoy the company of your future co-workers? Can you stay focused and motivated in the lab space?). I think one of the less important factors in choosing an advisor is the area of research – the research you do in your PhD thesis will probably not dictate what field you go into for the rest of your career, but it will have a long-lasting influence over the techniques you use and master, the way you design and implement experiments, and the way you communicate and disseminate your findings.
