PROFILE
Warren Szewczyk is a research scientist and statistical consultant at the University of Washington School of Nursing. He enjoys collaborating with faculty and students on the many exciting research projects happening across the school.
Although his academic background is primarily in mental health and psychology, his role at the School of Nursing has allowed him to contribute to a wide range of research areas. He brings his expertise in mental health and behavior to support diverse projects, including exercise clinical trials.
Outside of academia, he enjoys hiking and backpacking in the Cascades and on the Olympic Peninsula, often accompanied by his dog Reggie—who is always enthusiastic about outdoor adventures, as long as mosquitoes aren’t involved. He also plays jazz piano, which he has been studying for several years, and is a regular on the basketball courts at the UW IMA.
