Predictive Analytics Lab (PAL)

The goal of our research is to develop wearable sensor system and the associated algorithms for the prediction of life-threatening events in humans. Our focus is to develop systems for the prediction of apnea, bradycardia and hypoxia in preterm infants, detection of suicidal ideation in individuals with mental health conditions, and detection of cravings in individuals with substance abuse. Our work is funded by grants from National Institute of Health, National Science Foundation and Department of Veterans’ Affairs.

Wearable Sensors To Improve Mental Health

Wearable sensor based framework for drug craving detection

We have been involved in the development of signal processing algorithms for the detection of mental health conditions using data collected using wearable sensors. Using gross body movement data collected with wearable sensors, we are developing innovative algorithms to detect suicidal ideation in individuals with depression, cravings and stress in individuals with substance abuse and effect of opioid toxicity.

Prediction of Life Threatening Events in Preterm Infants.

Apnea, a pause in breathing, is common in preterm infants (neonates). Respiratory pauses lasting beyond twenty seconds result in dangerously low tissue oxygen levels that can cause damage to the heart, lungs, and brain. Many low-weight, pre-term infants subsequently exhibit neurobehavioral problems, including deficits in cognitive function, neuropsychological abilities and academic achievement which may be related to recurrence of apnea of prematurity or to the indirect consequences of chemical interventions used to treat the life threatening cessations in breathing. We focus on developing signal processing and machine learning algorithms to predict the apnea and bradycardia.
