Stochastic processes in ecology

Sadly, we lost a lab alumnus in 2020, when Ben passed away following a long battle with a chronic disease. Ben’s research on applications of the quasi-potential to questions of ecological stability opened important new research avenues that my lab and others continue to pursue. After leaving my lab, Ben dedicated himself to educating the next generation of math students, with a particular emphasis on supporting students from underrepresented groups. A scholarship fund has been established in his name at the University of Nebraska – Lincoln; donations can be made here. As a talented researcher, inspirational teacher, and exceptionally kind and funny person, Ben is deeply missed by all who were lucky enough to have known him.
