Sophomore David Zhen discusses his research on neuroblastoma with Rep. Dale Kildee (D-Flint) April 19 in Washington, D.C. The Council on Undergraduate Research annually sponsors a day in the Capitol for students from across the country to present results of their independent research in science, engineering and mathematics. The presentation by Zhen, one of 60 undergraduates invited to display their work for members of Congress, featured research he is conducting in the laboratory of Eva Feldman, professor of neurology, under direct supervision of Tracy Schwab, research investigator in the Department of Neurology. Their collaboration is part of the University's Undergraduate Research Opportunity Program. (Photo by Mike Waring, U-M Washington, D.C., Office)
