Principal Investigator


Catherine J. Chu, MD, MMSc, MA

Dr. Chu is an Assistant Professor at Harvard Medical School and a board-certified child neurologist and neurophysiologist at Massachusetts General Hospital. She divides her time between clinical efforts and research endeavors . Clinically, she cares for children with pediatric epilepsy and interprets pediatric and adult EEGs for diagnosis and management. Dr. Chu manages the inpatient Pediatric EEG service at MGH and the high density EEG program in the MGH epilepsy monitoring unit.  Following her clinical training, Dr. Chu participated in an advanced clinical investigator training program during which she developed skills in data analysis and advanced signal processing as well as clinical trial design and statistics. She is passionate about caring for children with epilepsy and better understanding this disease, with an emphasis on optimizing non-invasive information used for epilepsy surgical planning, understanding the impacts of epilepsy and abnormal physiology on brain development, and identifying reliable signals to guide clinicians in treatment decisions to improve developmental and epilepsy outcomes.

Lab Members

Wen received her PhD degree in Electrical Engineering from Nanyang Technological University, Singapore in 2015 and Bachelor of Engineering degree in Computer Science from Jinan University, P. R. China in 2011. Wen has worked on various types of analysis of biomedical signals including ECG, EEG, PSG, MRI, and acoustic signals. She is interested in building automated analytic models by developing predictive, actionable algorithms for better performance and efficiency. In the Chu Lab, Wen will work on evaluating childhood epilepsy with centrotemporal spikes (CECTS) with a focus on automated sleep staging and spindle detection.
