NECTOW LAB TEAM

Alexander Nectow

Principal Investigator

Alexander R. Nectow is a Principal Investigator on the faculty of Columbia University’s Department of Medicine. He received his B.S. and M.S. degrees in Engineering Science and Biomedical Engineering, respectively, from Tufts University in 2011. He earned his PhD from Rockefeller University in 2015, during which he developed novel molecular profiling technologies and identified the dorsal raphe nucleus as a key node regulating food intake. Shortly after completing his PhD, Alex started his laboratory as a CV Starr Fellow at Princeton University’s Princeton Neuroscience Institute in 2016. At Princeton, Alex's group identified a novel mechanism through which the brainstem regulates thermogenesis. During this time, Alex also began to pursue an MD at Columbia University. Alex joined the faculty of Columbia University’s Department of Medicine in 2019, shortly before completing his MD in 2020.

Alex has been recognized with a number of honors and awards, such as The Rockefeller University’s David Rockefeller Fellowship, Princeton University’s CV Starr Fellowship, Columbia University's Titus Munson Coan Prize, and the American Diabetes Association’s Innovative Basic Science Award and Pathway to Stop Diabetes Accelerator Award. He was also recently a NARSAD Young Investigator.

Nachiket Kamatkar

Postdoctoral Fellow

Nachi received his BS and MS from the University of Notre Dame. His master’s thesis was on swarming motility of Pseudomonas aeruginosa in the laboratory of Joshua Shrout. For his PhD, Nachi moved to Albert Einstein College of Medicine, where he studied FGF signaling in the central nervous system in the laboratory of Jean Hebert and developed RNA aptamers specific for FGFR3, in collaboration with Dr. Matthew Levy. In the Nectow lab, Nachi is interested in studying circuit dynamics of the dorsal raphe nucleus and its role in circadian rhythm and hunger. He is also interested in developing novel viral and chemogenetic strategies to identify and dissect neural circuits required for energy homeostasis.

In his free time, Nachi enjoys exploring NYC, playing chess, and visiting breweries.

Varun Bhave

Research Technician

Varun received his AB in Neuroscience from Princeton University in 2019. He worked with Dr. Nectow throughout his undergrad years and also completed a senior thesis in the lab of Dr. Michael Berry II, using two-photon calcium imaging to study temporal sequence learning in primary visual cortex. In the Nectow lab, he is interested in better characterizing the cell-type heterogeneity of excitatory and inhibitory neural subpopulations in the DRN.

Outside of the lab, Varun enjoys reading philosophy and is perennially trying to improve his ping pong game.

Marc Schneeberger

Collaborator

Marc received his PhD from the University of Barcelona under the supervision of Dr. Marc Claret to understand how mitochondrial dynamics in POMC neurons regulate energy balance. For his postdoctoral studies, he moved to New York City and has worked under the supervision of Prof. Jeffrey Friedman, where he has been characterizing two subsets of neurons in the brainstem’s dorsal raphe regulating energy homeostasis. For this work, Marc has been collaborating with the Nectow Laboratory at Princeton University, and more recently Columbia University. Marc is now interested in uncovering premotor cell types and circuit involved in the regulation of thermogenesis.

In his free time Marc enjoys traveling, reading books and practice sports. He is also an extreme foodie.
