David Sullivan is currently a Research Assistant Professor at Northwestern University in the Pathology Department. Dr. Sullivan's research focuses on the mechanisms and signaling pathways involved in leukocyte-endothelial interactions during diapedesis, the process by which leukocytes leave the blood stream and gain access to tissue. To dissect these complex intercellular interactions, Dr. Sullivan has helped develop in vitro and in vivo imaging techniques. He has also pioneered methods to follow leukocytes, endothelial cells, and parasites (T. cruzi) in the brain, gut, and general vasculatures of live animals. Dr. Sullivan received his BS in Biochemistry from Indiana University. While there, he worked with John Richardson studying the bacterial transcription termination factor Rho. Dr. Sullivan then joined the Biochemistry Graduate Program at the University of Wisconsin - Madison in the lab of Anant Menon studying the mechanisms underlying the intracellular transport of sterols between different organelles in Saccharomyces cerevisiae. Partway through his thesis work, he moved with the lab to Weill Cornell Medical School in New York City. After graduating, he joined the lab of William Muller in Chicago as a postdoctoral research fellow and has been there ever since 2008. In addition to research, Dr. Sullivan is committed to mentoring and community outreach. He has been involved with several local outreach organizations including the Boy Scouts of America – STEM Scouts program, Northwestern’s Science in Society program, and CHIentist, an organization that seeks to bring together academicians, professionals, and community members to foster interactions and collaborations. Dr. Sullivan has been a member of American Society for Investigative Pathology since 2008 and has served on the program committee and as an organizer of the Vascular and Mucosal Pathobiology (VAMP) Scientific Interest Group. He has received the Young Scientist Leadership and the Experimental Pathologist In Training awards.
