Research Summary

I’m a developmental psychologist with a strong interest in statistical modeling of trait- and state-level behavioral data to better understand self-regulation in multiple domains including driving safety in at-risk populations. To date, at-risk populations have included healthy and diseased aging, obstructive sleep apnea. These studies will expand to include brain injury patients and adolescents. Driving safety assessments include multiple platforms including simulation, real-world driving with instrumented vehicles, and black-boxes in participants’ own vehicles. EEG, peripheral physiology, and eye-trackers are integrated into our simulation environment permitting enriched assessments of self-regulation of attention. I also have strong interests in individual differences specifically how personality and affective factors relevant to risk-taking intersect with attentional self-regulation to influence driving safety. A better understanding of self-regulatory processes and how they bear on tactical and strategic decisions that bear on driving safety will inform intervention efforts to improve safety outcomes and public policy.
