Research Interests

Welcome to the Jacobs Lab at McDaniel College! I’m fascinated by the life histories of marine organisms, and particularly the ecology and development of marine invertebrate larvae. My work is driven by questions such as: How do larvae vary within and between species and populations? What are the consequences of those differences? Does larval behavior vary predictably within and between populations? In my lab, we address these questions using larvae of diverse organisms such as ascidians (sea squirts), lobsters, and more!

My summer research students usually come with me to a field station (Woods Hole Oceanographic Institution or Friday Harbor Laboratories) for an intensive research experience; I also occasionally take on smaller lab-based student projects during the year. I encourage interested students to contact me directly.
