Jui-Chun “Freya” Chen

Ms. Freya Chen currently works on various seismological problems related to sea ice and ice shelves. She has recently completed a field season in the Arctic (with Prof. Derek Mueller’s Group at Carleton University in Ottawa, Canada) to deploy seismometers on the Milne Ice Shelf, Ellesmere Island, Nunavut, Canada.  She also does theoretical work involving how sea ice modifies microseism in seismic records.  She is co-advised by Prof. Sunny Park.

Peter Nekrasov

Mr. Peter Nekrasov is a student in the Computational and Applied Mathematics Department here at the University of Chicago. Peter and I work together on various problems involving the propagation of flexural gravity waves in ice covered oceans. I help advise Peter along with his main academic advisor, Prof. Mary Silber. Recently, Peter and I published a paper that describes how periodic structures on ice shelves, such as the “rolls” (surface undulations) on the Arctic Ice Shelves of Ellesmere Island can upset the propagation of such waves. Peter is interested in numerical methods for PDEs and their applications to geophysics and fluid dynamics. His hobbies include music, hiking, and birdwatching. His favorite team is the New Jersey Devils.

Undergraduate Students

Joshua (Chang Hyeon) Park

Mr. Joshua Park works with me on various problems involving the oceanographic circulation near collapsing ice streams. He is interested in the subject of glacial geoengineering, as it has arisen at the University of Chicago by the creation of the new Climate Systems Engineering Initiative (CSEi).

Anna Kilpatrick

Ms. Anna Kilpatrick works with me on the analysis of 360° time-lapse camera photographs from the George VI Ice Shelf, Antarctica. We have a 90 day time series of photographs taken every 20 minutes. Our plan is to use the photographs to examine the relationship between cloud cover and the absorption of solar energy of the ice-shelf surface.
