I am currently a graduate student finishing up my phD in Biomedical Engineering at the Auditory Neuroscience Laboratory, Center for Computation Neuroscience and Neural Technology at Boston University, (Boston, MA). I am also affiliated with the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH; Charlestown, MA)  and the McGovern Institute of Brain Research at Massachusetts Institute of Technology (MIT; Cambridge, MA) where I conduct some of my human neuroimaging experiments.

My work is interdisciplinary in nature and is broadly based on the use of signal processing and statistical methods along with behavioral experiments, computational models and neuroimaging techniques to study the mechanisms underlying perception in typical humans and in neurological disorders such as autism. In particular, I am interested in how we process sounds and analyze acoustic scenes that contain many sources of sound such as in everyday environments.  The overarching goal of my research is to develop methods and devices that will (1) assist patients with hearing difficulties, (2) serve as biomarkers for neurological disorders,  (3) decode brain signals for brain-machine interfaces and (4) mimic perception in machines.  Please visit my research page for more information.
