Our current work (supported by NIH Center of Excellence for Mobile Sensor Data-to-Knowledge(MD2K)), several R01s and U01 from NIH, and several grants from NSF seeks to define new frontiers in the newly emerging discipline of mobile health (mHealth). Our decade-long work has involved collecting mobile sensor data from 100+ human volunteers for 25,000+ hours in their natural environments as part of various scientific user studies. From these real-life sensor measurements, we have developed robust models to detect several important biomarkers from mobile sensor data. They incliude estimating stress and craving (from physiological sensor data), and detecting smoking (from smartwatch and respiration data), cocaine use (from heart rate data), and conversation (from respiration data).
Our recent work is aimed towards discovering patterns in time series of biomarkers to determine triggers for delivering just-in-time mobile interventions. See ACM UbiComp'14 work and ACM CHI'16 work. Some of our recent works have been aimed at developing methods to ensure behavioral privacy. See ACM CHI'11 work and ACM UbiComp'16 work.
Our research involves more than twenty faculty members from fifteen institutions (Cornell Tech, Georgia Tech, Johns Hopkins, NIDA Intramural Research, Northwestern, Michigan, Ohio State University, Rice, UCLA, UCSD, UCSF, UMass Amherst, UPenn, University of Minnesota, and West Virginia). Our collaborators span a variety of disciplines (e.g., Computer Science, Electrical Engineering, Mathematics, Statistics, Psychology, Behavioral Science, Cardiology, Physiology, Public Health, etc.), making our projects highly transdisciplinary.
Our prior work led the foundation for coverage and
connectivity in wireless sensor networks.
We introduced two new models of coverage, Barrier
Coverage (for intrusion detection) and Trap
scalable tracking with provable guarantees). With our esteemed
colleagues (Bela Bollobas and Paul Balister), we introduced an
analytical technique for deriving reliable
for probabilistic events, obviating the need to insist on large network
size to make probabilistic guarantess (as is traditionally done in
making "with high probability" claims). We applied this technique to
derive reliable estimates of density to achieve barrier
coverage, full coverage, connectivity,
demonstrating its wide applicability. Our work on trap
coverage explained the entire continuum between percolation
and full coverage.
In an earlier systems work, we developed the AutoWitness burglar tracking system to help law enforcement agencies in recovering stolen assets. AutoWitness can detect burglary without an explicit report from the owner, instantly notify law enforcement agency, and most importantly, provide real-time updates on the current location of assets while en-route, maximizing the chances of timely recovery.
