Assistant Professor
Khoury College of Computer Sciences and the Bouvé College of Health Sciences
Northeastern University
About the Presentation: This talk explores a new computational perspective on digital biomarkers, arguing that they are best understood as manifestations of latent human states that evolve over time rather than as static traits. Drawing on Dr. Sathyanarayana’s work in sleep and sleep apnea, maternal and reproductive health, youth relationship health, bipolar disorder and mental health, and orthopedic injury, it highlights how multimodal data from smartphones, wearables, EEG, text messaging, imaging, and movement sensors can be used to model health and behavior as dynamical systems. By centering states, transitions, and temporal structure, the talk proposes a more principled foundation for digital biomarker discovery.
About the Presenter: Dr. Sathyanarayana is an Assistant Professor at Northeastern University working at the intersection of computer science, health, and digital biomarker discovery. Her research focuses on developing computational models that transform multimodal data from smartphones, wearables, EEG, text messaging, imaging, and movement sensors into meaningful representations of human health and behavior. She has applied this work across sleep and sleep apnea, maternal and reproductive health, bipolar disorder and mental health, youth relationship health, and orthopedic injury. Through this research, she aims to build a more principled foundation for digital health, one that treats health as a dynamic process rather than a static measurement.
