Jill Marshall (she/her). I'm a professor at the Univ. of Arkansas. Went back to school (community colleges to start) in my 30s, and, after two decades working on stream protection I returned to school at 49 years young. Now I study what makes rock fall apart (weathering and sediment production via ice and trees) and creep, ooze, slide or bounce downhill. In this photo, I'm hiking into our Arctic field site where we are trying to disentangle the role of climate in changing sediment production and transport processes and rates from the rock walls down to the Mackenzie Delta. This is a collaborative project with Marisa Palucis and Justin Strauss (Dartmouth).
