Finding, building and maintaining collaborations is extremely important. Indeed, my best collaborators have had a huge influence on my thinking, my career, and my choice of problems. Working with some of the best scientists in the world is extremely rewarding and provides extraordinary opportunities to have an impact on the lives of millions of people. I maintain collaborations in multiple areas of research including sleep, aging, multiple sclerosis, stroke, Alzheimer's Disease, and cancer. New technologies increasingly permeate all areas of medical and health research, which makes my expertise in high density, high resolution medical signals increasingly useful. A deep knowledge of new technologies leads to much improved design of experiments and much faster reaction times to changes in the variety and volume of new data. Often we are approached by collaborators who work in completely new areas because I and my research groups are among the few whop would take such new risky, but highly rewarding, projects.
