His team raised more than $300,000. Samantha Saeger ’04 was on the U.S. team that won the Björn Kjellström Cup in the North American Orienteering Championships in Arnprior, Ont., in October. Teams vie in three individual races and a team relay. Leading in points for her team, Saegar provided a come-from-behind, last-leg effort in the relay to secure the win. * In the fall Melissa Mullen Davis ’05 began a term as president of Graduate Women in Science, which seeks to advance the participation and recognition of women in science and to foster research through grants, awards, and fellowships. Davis is a postdoctoral research fellow in molecular genetics at the Cleveland Clinic’s Lerner Research Institute. * In November Dan Vassallo ’07 won the 2014 Philadelphia Marathon with a time of 2:17:27, qualifying him for the 2016 U.S. Olympic Team Trials.
