Current research interests include studying the influence of affective state on individual decision making, group decision making, and mental workload assessment; personality characteristics and individual differences in perception and preference for workload levels; and the examination of the effects of workload and stress on situation awareness in a dynamic decision making task.

Ongoing research projects include: The role of risk taking in pilot decision making with an emphasis on pilots' perception and assessment of the multidimensional components of risk (supported by NASA), Individual differences and personality traits in risk-taking and mental workload perception and preferences: Assessing the predictive validity of SWAT as an individual differences measure of preferences for mental workload levels, The effects of framing of task performance strategies on performance in a multiattribute dynamic decision making work environment and on situation awareness (supported by NASA), The influence of positive affect, perceived threats, and opportunities on the decision rule in risk situations (partially supported by the Mershon Center).
