Megha Ghosh
Postdoctoral Fellow
Computational Neuroscience
I am an electrical engineer turned neuroscientist. I love brain rhythms and enjoy making sense of the electrical activity of the brain. I want to understand the algorithms of the brain and use those coding schemes to debug pathological states.
