I work with Dr. Michael Coughlin and LIGO on low-latency alerts for gravitational wave events. Upon detection of a gravitational wave signal from a merger of neutron stars or balck holes, an alert needs to be sent out within seconds alerting astronomers to search for the electromagnetic counterpart to the gravitational wave event. This alert contains crucial information about the gravitational wave event, and I am currently investigating the resulting distributions of mass ejecta and luminosity of these binary neutron star and neutron star-black home mergers to better inform the alert system. 

Beyond my research, I am from Wisconsin and went to the University of Notre Dame for my undergraduate studies. In my free time, I enjoy playing sports and being active. I also love spending time in the northwoods fishing, boating, and swimming with my family and friends.
