The Addiction Recovery Research Center (ARRC) is a research unit located on the third floor of the Virginia Tech Carilion Research Institute in Roanoke, VA. Directed by Warren K. Bickel, PhD, a recognized addiction researcher, ARRC is dedicated to understanding addiction and developing new treatments that repair the impaired decision-making processes common in addictive disorders. We have many specialized resources available to study addiction in innovative ways, including private offices and interview rooms, individualized computer therapy rooms, a ventilated smoking laboratory for measuring smoking behavior, access to three research-dedicated functional magnetic resonance imaging scanners, and access to brain stimulation equipment for transcranial magnetic simulation.
