Dr. Angela Liegly-Dougal

My research represents a collection of projects that are designed to test an over-arching conceptual model of the effects of stress on mental and physical health outcomes. I define stress broadly as a whole person response. Most prominent is the negative emotional response; however, it is accompanied by predictable changes in biological systems, cognitive processes, and behavioral patterns. These changes are directed at either altering the source of the stress, or the stressor, or accommodating its effects. All of these changes are inherently adaptive but prolonged or extreme alteration can lead to physical and mental health problems. Therefore, I try to measure all dimensions of stress and stress-related processes whenever feasible. Most of the research that I conduct is done in the field by going into the community to the participants’ locations and capturing real-world stress using longitudinal quasi-experimental or mixed quasi-experimental and experimental designs. As such, I have done research with numerous populations, including healthy participants, victims of traumatic events, and patients with chronic and life-threatening diseases such as cancer, chronic pain conditions, and metabolic diseases. I also have a programmatic line of research examining adoption and maintenance of physical activity.



Dr. Jared Kenworthy

My research is in social psychology, and focuses on intergroup relations, group processes, as well as the interplay between these two areas. Within intergroup relations, my focus is on ingroup identification, the sources of prejudice, intergroup threat, and the reduction of prejudice and discrimination. Group processes include ingroup identification, group cohesion, collaborative creativity, and information exchange. These two areas of research have generally been distinct, but we are beginning to merge them in ways that yield new multi-level models and unique predictions about the mutual influence of individual, intragroup, and intergroup processes. Another area of interest concerns the social factors that predict and sustain behavioral intentions and changes in a variety of domains, such as health, workplace, religious, and political behavior.




Dr. Paul Paulus

My research focuses on group, team, and network collaboration.  Many of our studies have focused on creativity tasks to understand the factors related to the development of creative ideas in collaborative settings.  Recent studies have examined the relationship of the prior interactional processes to the final product and interactions among teams.  We also have an interest in using data from group interaction to form optimally functioning teams.  Our research findings and theoretical models can applied to the performance of scientific and medical teams.






Dr. Jianzhong Su

Dr. Jianzhong Su

Dr. Jianzhong Su, Professor and Chair of Mathematics at UT Arlington, is an applied mathematician with expertise in computational neuroscience and partial differential equations. His recent focus is inverse problems with applications in optical tomography and EEG source reconstructions. He has collaborated extensively with other neuroscientists, engineers and medical doctors on medical imaging, neuroscience, medical implants and related areas. He has published systematically on Diffuse Optical Tomography, neuron synaptic transmission, neuron electric activations (bursting) and their modeling and simulations. He is an experienced researcher,  has served as PI/co-PI on about $3.5 million external funding over the last 20 years, published over 50 peer-reviewed journal papers and been invited to 45 seminars and conferences. 

He and his team are working on various issues of computational neurosciences and study brain abnormal behavior, particularly related to seizure, pain, PTSD and other neurological issues.
