Selected Projects
Socio-behavioral features differentiating depression and psychosis patients from healthy controls
In this project, we use continuous audio recordings from free-living across multiple days to automatically infer a subject's in-person social network and derive socio-behavioral features relevant to diagnosing and monitoring depression and psychosis.
Speaker Diarization for free-living audio recordings
In this project, we are developing an accurate and contextualized diarization processing pipeline for processing audio from free living. This is being developed in the context of ongoing mental health application projects and could likely be useful for several other healthcare and consumer applications.
Patient monitoring theme [Expertise: Machine learning and computer vision]
Machine learning model for actigraphy
Deep learning model for scene understanding
Patient status monitoring and deterioration detection using physiological signals
Cloud Data Platform theme
Generic, scalable framework for (real-time) data acquisition from connected devices, real-time processing, storage, distributed computing, and visualization. Support for different user models in the platform: data producer, study administrator, researcher, and observer.
Architected and implemented the data platform with the above framework on the AWS cloud. Stack: s3,Kinesis,Lambda,EC2,Cognito,DynamoDB,EMR,RDS,Glacier
