I am experienced in statistical modeling and machine learning, particularly for health applications.
Worked with Dr. Maja Mataric as part of the SURE REU program. Laid groundwork for research project investigating socially-assistive telepresence robots for the K-12 classroom. Wrote and documented ROS code for operating the Ava telepresence robot. Implemented features include affective light indicators, autonomous navigation, and remote video conferencing.
Designed human-in-the-loop air traffic detection system for semi-autonomous UAV. Co-developed decision-level Bayesian fusion algorithm that improved accuracy of results from computer vision methods (e.g Kalman filter). Effectively tracked and detected flying object in controlled video data.
Implemented user-friendly online data visualization dashboard for mobile crowdsensing app. Applying ML and signal processing methods to extract informative features from smartphone sensor data streams and model different activity contexts.
Statistically modeling the effect of digital communication patterns on reported loneliness within a college student population.
Implemented Monte Carlo simulation to observe the effect of ECG signal corruption on heart rate complexity algorithm results. Addressed convergence of hypoxic and non-hypoxic ECG datasets under noise.
Developed a mobile virtual agent application for cervical cancer education. Analyzed user interview results and app usage data to determine the effectiveness of culturally-tailored health technology for rural Hispanic farmworkers.
Implemented web-based conversational agent using BotUI. End goal is to prototype conversational agent for EMA delivery as alternative to current mobile-based platforms. Click the project name to talk to SanjBot!
Apart from being a graduate student, I enjoy reading, listening to podcasts, and practicing yoga. I'm also working on a conversational agent for EMA delivery as a side project (SanjBot)
