Nickhil Jakatdar is the Founder and Chairman of Preventive Health AI, where he's working to democratize longevity science and make preventive health accessible to everyone, not just the wealthy few.
Diagnosed with heart disease at 43, he used what he calls the 3D's - doctors, dietitians, and data - to reverse the course of aging. Today at 53, all his blood markers are in the green and his cardiovascular age is 38!
He holds a Ph.D. in Electrical Engineering and Computer Science from UC Berkeley and previously co-founded Vuclip, a mobile video platform that scaled to 41 million users before being acquired by PCCW, and has also founded multiple startups across semiconductors, mobile video, and molecular diagnostics. With 60+ patents to his name, he was a TEDx speaker and is the youngest recipient of UC Berkeley's Distinguished Alumni Award. He currently serves as CEO of GenePath Diagnostics and sits on the advisory boards of the South Asian Heart Center and CITRIS.
