I am a biomedical engineer, postdoctoral researcher, at National Eye Institute, NIH, advised by Dr. Stanislav Tomarev. Before joining NIH, I received my Ph.D. degree in Biomedical Engineering at Brown University, advised by Prof. Jonghwan Lee. I am specializing in minimally invasive neurotechnologies for vision restoration, neural protection, and neural regeneration. My work integrates nanotechnology, neurobiology, and optical stimulation to develop minimally invasive retinal prosthetics and neuroprotective strategies for eye diseases.
Open Positions
I welcome inquiries from postbac researchers and graduate students from diverse background interested in NIH training programs and in joining Dr. Tomarev’s lab. Prospective candidates are encouraged to explore NIH opportunities such as the Postbac IRTA, Summer Internship Program, and Graduate Partnerships Program (GPP).
