Sreekanth Chalasani

Professor

I obtained my B.S. from Osmania University and an advanced diploma in Computer Science. I then did research at the National Center for Biological Sciences in Bangalore before coming to the US in 1997. I obtained my PhD from the University of Pennsylvania and did post-docs at University of California San Francisco and The Rockefeller University. I started my lab in 2010 where I am lucky to have an amazing group of scientists working with me. I love cereal, honey and soccer!!

Kathleen Quach

Postdoctoral Fellow

I received a B.S. in Neuroscience from UCLA. I completed my Ph.D. in Neurosciences at UCSD, with a specialization in computational neuroscience. I study the foraging strategies used in interactions between a predatory nematode (Pristionchus pacificus) and a prey nematode (Caenorhabditis elegans) that both compete for the same food (bacteria). I explore how P. pacificus chooses between aggression and predation, as well as how predator imminence influences how C. elegans interacts with bacteria. I like history, hard sci-fi, species diversity, permaculture, and manufacturing processes.

Michael Rieger

Postdoctoral Fellow

Mike received his BS at the University of Illinois Urbana-Champaign, and his PhD at Washington University in St. Louis in Molecular Cell Biology in the laboratory of Dr. Joseph Dougherty. He is interested broadly in the molecular mechanisms underlying variability phenotypes at the cellular and organismal level: What makes two cells of the same class respond differently to a stimulus? What makes two animals of the same genetic background behave differently in response to their environment? He plans to explore these questions in C. elegans. Outside of science, he enjoys traveling, aerial acrobatics, variety theater, fun photoshoots, film festivals, record collecting, old pieces of technological equipment, baking bread, and comparative linguistics.

Wen Mai Wong

Postdoctoral Fellow

Wen Mai received her B.S. in biology from St. Mary’s University and her Ph.D. in Neuroscience at the University of Texas Southwestern Medical Center under Dr. Julian P. Meeks. She is currently working on developing sonogenetics, a tool which uses ultrasound for non-invasive manipulation of cells and neurons. In particular, she is working on understanding the mechanism of ultrasound stimulation and discovering novel ultrasound-sensitive channels. During her free time, Wen Mai can be found doing a variety of activities including rock climbing, drawing and playing video games.
Callum-Walsh

Callum Walsh

Postdoctoral Fellow

For my undergraduate degree I undertook an integrated Masters in Pharmacology at the University of Bristol, during which I spent a year in Neuroscience Drug Discovery at Janssen Pharmaceuticals, investigating electrophysiological biomarkers of tau pathology in a novel mouse model of Alzheimer’s Disease. I did my PhD in Neuroscience in the lab of Jon Brown at the University of Exeter, where we discovered a number of novel functional correlates of contextual memory in the mouse retrosplenial cortex. As a postdoctoral fellow in the Chalasani Lab, I will be working on developing sonogentics as a tool for non-invasive neuromodulation using ultrasound (US). Specifically I will be using electrophysiology to characterise neuronal responses to US stimulation and develop novel US-sensitive channels and US stimulation protocols both in vitro and in vivo, in awake behaving mice. In my free time I enjoy cooking and playing video games, as well as tinkering on different projects such as 3D printing and coding. I love to travel and I am looking forward to exploring the United States during my time at the Salk Institute.

James Britton

Visiting Researcher

James Britton received a B.Sc. in Human Physiology from the National University of Ireland, a M.Sc. in Regenerative Medicine from NUI Galway, followed by a Ph.D. in Biomedical Engineering focused on Neuroengineering from the University of Galway, Ireland. Since Graduating, he received an Irish Research Council Postdoctoral Fellowship to research in the Physiology Department on a Neuromodulation project. Currently, James is a Fulbright Postdoctoral Fellow in the lab researching the use of Sonogenetics/acoustic Neuromodulation as a tool to non-invasively modulate cells in the nervous system. This research is being approached from a bioengineering perspective with the aim of creating devices and techniques to treat neurological conditions. During his free time, James enjoys hiking, sea swimming, jogging, and doing home DIY projects.
JessHaley-767

Jess Haley

Graduate Student

Jess received a M.S./B.S. in Neuroscience from Brandeis University where she studied the interaction of speech comprehension and balance in older adults in the Ashton Graybiel Spatial Orientation Laboratory. She then worked as a research technician in Dr. Eve Marder’s lab studying basic mechanisms of circuit robustness and variability in the nervous system of the crab, Cancer borealis. Jess is currently a Ph.D. student in the Neurosciences Graduate Program at UCSD. She is studying the computations underlying sensory-evoked behaviors in the nematode, Caenorhabditis elegans. Jess spends her time outside of the lab advocating for science as the Co-President of Science Policy, Advocacy, and Communication (SciPAC) at UCSD. Her hobbies include cycling, rock climbing, baking, and tinkering.
Zion-Igwe

Zion Igwe

Research Assistant I

Zion graduated from UCSD in 2022 and is currently a research assistant. He conducts resident-intruder experiments to explore the role of various circuits in the aggressive behaviors of mice. His hobbies include playing video games, exercising and cooking A LOT of food.
Megan-Anderson

Megan Anderson

Graduate Student

Megan earned her B.S. in Neuroscience and B.S. in Psychology from Virginia Tech University in 2019. She worked as a NIH Post-baccalaureate IRTA at the National Institute on Drug Abuse under Dr. Yeka Aponte before moving to San Diego to join the Neuroscience Graduate Program at UCSD. As a PhD student, Megan is studying the role of the vagal neurocircuitry in mouse behavior. In her free time, Megan is probably cooking, crafting or gardening.
Irene-Chen

Irene Chen

Undergraduate Student

Irene is an undergraduate at UCSD doubling in Neurobiology and Math-CS. In the Shrek lab, Irene is studying the foraging strategy of C. elegans in a patched environment. Outside of the lab, Irene enjoys playing the cello, reading, cooking, and visiting zoos and museums.
Maddie-Mitchell

Maddie Mitchell

Undergraduate Student

I am currently a 3rd year at UCSD majoring in Human Biology. I am exploring the neuronal differences between healthy and diseased-state worms by analyzing CEP, ADE, and PDR neurons and assisting Mike with organization and sequencing of plasmids. I swim for UCSD’s collegiate team since freshman year. I love to read hike and to do puzzles in my free time.
Josh-Park

Joshua Park

Undegraduate Student

I’m Josh, a second-year computer engineering major in Sixth College, UCSD. I am working with Megan using sonogenetics to study the role of vagal neurocircuity in behavior. Outside of the lab, I enjoy playing guitar and running around in Apex.
