Specifi- cally, ISU biology students and faculty presented their works at 76 scientific meetings last year and published 62 manuscripts (56 of which had one or more ISU students as authors). My first four years as director have flown by, and in hindsight it is easy to see why. We have made many advances in the school during this brief period. We have recruited seven new tenure track Michaela Lottes, a Ph.D. student, working with A pennycress seedpod, broken open to reveal John Fleming, one of eight undergraduates in faculty and three new support staff, its seeds, which contain 34 percent oil and 19 the Sedbrook lab percent protein by dry weight. overhauled the curriculum, upgraded all of our classroom technology, and 1970s.
