Whether it is experimenting with human cells in a petri dish, investigating animal behavior, or studying the effectiveness of potential medicines in people, Dr. Kevin Walton has worked in all these areas over his career as a scientist. We are lucky he is now online! His current focus is on treatments to help those who want to quit smoking. He is also working on efforts to understand more about the risks and benefits of electronic cigarettes. When not at NIDA, Kevin spends his time with his family, losing at ping pong but still able to win a pinball game here and there.
