I am a pre-doctoral MS student in computer science at the University of Chicago
and a human-computer interaction researcher.
My research in the Human Computer Integration Lab, where I am advised by Pedro Lopes,
focuses on sensing, wearables, and designing interfaces that utilize body movements for both input and output
by combining gesture sensing with muscle stimulation.
I received my BS in engineering and applied mathematics from Swarthmore College.
My previous research completed at Swarthmore, Lawrence Berkeley National Laboratory,
and Argonne National Laboratory has been published by the IEEE Signal Processing Society
and by the Acoustical Society of America.
I am now applying for PhD admissions in Computer Science and Electrical Engineering.
