I am currently a Research Fellow at the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH; Charlestown, MA). Prior to this, I completed 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 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 behavioral experiments and computational models along with non-invasive physiological measures such as otoacoustic emissions, electrophysiological and neuroimaging techniques to study the mechanisms underlying auditory perception. 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. To experimentally investigate auditory processing along different levels of the auditory pathway, I use otoacoustic emissions, electrophysiological responses from the brainstem and cortical spatio-temporal imaging methods such as electroencephalography (EEG) and magnetoencephalography (MEG). I also attempt to take advantage of the vibrant auditory research community in the Boston area through active collaborations. Though I often engage in basic scientific research, the overarching goal of my research is to help translate cutting edge knowledge of auditory neurophysiology to effective clinical tools. This includes developing methods and devices that will (1) assist patients with hearing difficulties, (2) serve as biomarkers for diagnosis and (importantly) stratification in clinical conditions such as central auditory processing disorders (CAPD) and autism spectrum disorders (ASD), (3) decode brain signals for brain-machine interfaces and (4) mimic perception in machines.
