Rathinaswamy Bhavanandhan “R.B.” Govindan, Ph.D., MS

Director of the Advanced Physiological Signals Processing Laboratory

Rathinaswamy “R.B.” Bhavanandhan Govindan, Ph.D., MS, is director of the Advanced Physiological Signals Processing Laboratory (APSPL) at Children’s National Hospital, overseeing the acquisition of high-quality signals, developing and maintaining automated analyses pipelines for processing these signals, and training end-users on the application of these analyses pipelines. The primary goal of APSPL research is identifying antecedents of brain injury in critically ill infants through continuous monitoring and characterization of multimodal physiological signals. Dr. Govindan has experience in developing monitoring tools to acquire and process data from patients’ bedside monitors. Using proprietary software, his team has continuously collected electrocardiograms and processed heartrate variability in close to real-time for several days from 100+ infants. He also has experience in collecting and processing data using wearable sensors (e.g., Everion, Biofourmis, Boston, U.S.). Using Everion, Govindan’ team reliably has collected heart rates from nearly 200 pregnant women and mothers of newborns to understand the onset of pregnancy-related stress or postpartum depression. Dr. Govindan’s current research focus is on real-time characterization of the physiological signals to derive biomarkers that can help to make informed clinical decisions. His team has honed several signal processing routines to address the highly prevalent artifacts in the physiological signals collected in a hostile environment of critical care monitoring. He has served as a Co-investigator on several National Institutes of Health grants.

RB received his Ph.D. in biomedical signal processing from the Indian Institute of Technology, Madras, Chennai, India. Recently, he received an MS degree in Biotechnology with a specialization in Bioinformatics from the University of Maryland Global Campus.
