Leah Simmons thought she knew exactly what she wanted, until she didn't. But she was able to figure out her way through co-ops and research opportunities.

Jonathan Tilly's infertility research has led to the birth of a baby born with an assist from stem cells. Tilly is the chair of the Department of Biology.
