Freshwater River Mussels
During my undergaduate degree at Macalester College, I spent two summers doing field and lab work researching environmental stressors impact on native freshwater river mussels in Minnesota Rivers. In the summer of 2015 I participated in field work where we conducted mussel population and diversity counts and collected stream velocity measurments.

Xenolith sample collection
In January 2016 I assisted Professor Alan Champan (Macalester College Department of Geology) with field work in Northern Arizona. Here we collected xenoliths samples for his research tectonic activity in the Colorado Plateau Transition Zone. You can learn more about the results of this work from articles published by him and his students below.
