Distinguished Yale professors Meg Urry and Mark Saltzman appeared at Harker’s upper school campus on Sept. 25 for a special science symposium arranged for students interested in pursuing science in college. Harker’s impressive science background made Nichols Hall an ideal venue for the event. Both professors spoke to the audience about their areas of research at Yale. Saltzman, chair of the department of biomedical engineering, discussed improving methods of medical drug delivery, and Urry, chair of the department of physics, talked about her research of black holes.
