Erik Herzog, PhD

Viktor Hamburger Distinguished Professor, Department of Biology; Director, St. Louis Neuroscience Pipeline Program

Erik is a chronobiologist, studying the molecules, cells and circuits that underlie daily rhythms in physiology and behavior. He is Professor of Biology and Neuroscience at Washington University.  He studied Biology and Spanish as an undergraduate at Duke University and Neuroscience as a graduate student with Dr. Robert Barlow at Syracuse University. He did postdoctoral research with Dr. Gene Block at the University of Virginia. In 2000, Erik started his lab at Washington University. His laboratory has discovered mechanisms underlying how circadian clocks regulate physiology, behavior and health.

Research Scientist

I received my Ph.D. from UNAM in Mexico City. My research aims to reveal the mechanisms of circadian regulation of olfaction and sleep-wake. I combine multielectrode array recordings, real-time luciferase monitoring, olfactometry, and locomotor assays. Here are some of my recent publications.

Nikhil Lokesh, PhD

Postdoctoral Fellow

After my baccalaureate in engineering, I earned my Ph.D. from JNCASR, India where I studied circadian clock evolution and chronotypes. As a Humboldt Postdoctoral Fellow in Charité – Universitätsmedizin Berlin, I explored the role of stochasticity in circadian clocks. Here in the Herzog Lab, I employ theory and experimental techniques to study network connectivity and synchronization of the SCN and seasonality in mice.

My other interests include psychology, philosophy and eastern mysticism.

Graduate Student

I am a graduate student in the DBBS Neuroscience Program. In 2019, I graduated from the University of Puerto Rico at Cayey with a B.S. in Natural Sciences. After graduating, I joined the Post-Baccalaureate Research Education Program (PREP) at UNC-Chapel Hill. Currently, I am interested in understanding how circadian rhythms regulate brain cancer progression and what approaches can we use to optimize current therapies by considering time of day.

Outside of the lab, I enjoy exploring new restaurants, watching TV shows, and planning vacations (especially to Puerto Rico).

Graduate Student

I am a graduate student in the DBBS Neuroscience Program. I graduated from the Universidad Nacional de Colombia in 2019. After college, I did research at the Universidad de Santiago de Chile and Albert Einstein College of Medicine. In 2022, I joined the Herzog lab to study the neuronal properties by which circadian rhythms synchronize in the SCN to regulate multiple behavioral outputs. In my spare time, I like to draw, paint, and read literature.

Graduate Student

Hola! I am a graduate student in the DBBS Neuroscience Program. In 2021, I graduated from Earlham College with a B.A. in Neuroscience. After graduating, I worked as a research technician in the Mennerick lab at WashU. I recently joined the Herzog lab and am excited to explore which/how circadian factors influence the progression of brain cancer.
Outside of the lab, you can catch me coaching and playing field hockey, trying new restaurants, being in nature, and planning travels.

Undergraduate Researcher

I am an undergraduate planning to major in Biology on the Neuroscience track, and I joined the Herzog lab in January 2022. Currently, I study the rapid splitting of mouse circadian system rhythms in response to enhanced behavioral feedback. Outside of school, I can be found playing guitar and bass, going on road trip adventures, and reading history books.

Undergraduate Researcher

I am an undergraduate student (junior) majoring in Neuroscience on a Biology track. I joined the Herzog lab in September 2022, researching daily rhythms in glioblastoma growth. I’m interested in the area of neuro-oncology and using chronobiology to improve the efficacy of existing treatments. In my free time, I love hiking with friends, playing tennis and violin, and watching some good movies.

Undergraduate Researcher

I am an undergraduate student majoring in biology with a concentration in neuroscience. I joined the Herzog lab in spring of 2023. I study the role of the sodium leak channel in circadian rhythms of the mouse SCN. Outside of the lab, I enjoy watching and playing sports, going to the gym, and being out in nature.
