I am a postdoc at Johns Hopkins University working with Professors Suchi Saria
and Michael Rosenblum
. I completed my PhD in 2018 at UMass working in the Machine Learning for Data Sciences
lab with Prof. Benjamin Marlin
COMPSCI 590N: Introduction to Numerical Computing with Python
I am interested in probabilistic and latent variable modeling, inference methods for these models, and the application of these models to problems in health and ecology.
Health Monitoring with Wearable Sensors
The emerging field of mobile health (mHealth) seeks to replace the use of self report data with continuously recorded physiological data streams collected using wearable sensors. While mHealth technologies have the potential to yield novel insights into health and behavior, significant data analysis challenges must first be overcome. In particular, I work on novel structured predcition models for detecting activities of interest, such as smoking and eating, while integrating out the uncertainty caused by imperfect observation processes.
Targeted Health Messaging
Behavioral science research has shown that periodical targeted messaging (via email, text message, etc.) can improve the success of smoking secession rates as part of a comprehensive treatment plan. Furthermore, evidence suggests that targeted messaging is more effective if personalized. The goal of this project is to develop and deploy a targeted health messaging system based around current recommender system technologies.
