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!!

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
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.

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 neural responses to ultrasound. In her free time, Megan is probably cooking, crafting or gardening.

Yanlin (Sunny) Liu
Graduate Student
I graduated from UCSD in 2023, majoring in Neurobiology and Clinical Psychology. I am broadly interested in the pathogenesis of psychiatric disorders, focusing on the stressors that induce disease onset, neural circuitry, and signaling pathways at the cellular and molecular level. In my free time, I enjoy getting boba and gaming with friends.

Lauren Holley
Lab Technician I
Lauren is a third-year undergraduate student at UCSD, perusing a double major in Cognitive and Behavioral Neuroscience and Public Health with a Concentration in Epidemiology, and a minor in General Biology. She is working with Wen Mai in the sonogenetics team to create a noninvasive neural modulation, and more specifically to screen better candidates for ultrasound responsive channels. In her free time, you can find Lauren hiking, traveling, reading, and trying new foods!

Keena Srikrishnan
Lab Technician I
Keena is currently a junior studying cognitive neuroscience at UC San Diego. In the lab, she works with Wen Mai to study how ultrasound could be used in cells and neurons. In her free time, she enjoys reading, painting, hiking, and spending time at the beach.

Juliana Pizano
Lab Technician I
Juliana, 3rd year at UCSD, biochemistry major, working under Megan.
