I'm here to share two things. One, through my work, how neurons take stress and actually show resilience. And two, through my work and how I worked at isotherapati, how we built up certain things from nothing because started in 2015.I'm I'm one of the first biology faculty who entered a room with really nothing and brought a lot of things today stands for everything that I'm going to show you. When I just walked this morning besides the beach, I could smell the Shenbagapu after several years all the Malipu ...
