My research examines the role of nonverbal communication in the contexts of hostile intent/threat assessment/adversarial behavior, deception, and mental health. I am particularly interested in how emotional states impact our behavior and subsequent interactions with others. My current research that is relevant to law enforcement and warfighters examines behavioral cues in emotionally charged high-risk/high-consequence situations that may be associated with hostile and non-hostile intent. Of particular interest is situational awareness and what we are attending to in our immediate environment and how we use this information to inform decisions about our actions. Additionally, I am interested in the nonverbal cues linked with people's gait patterns when they attempt to conceal an object and differences in gesture use in truthful and made up accounts of a lived experience. With respect to mental health, current projects include exploring body language and facial affect as diagnostic criteria for depression. I have worked on research projects funded by DARPA, Department of Homeland Security, the National Science Foundation, and the Naval Research Laboratory.
