Dr. Jeremy Hamm is an Assistant Professor of Psychology at NDSU. After earning his Ph.D. at the University of Manitoba and completing an internship at the Institute for Psychogerontology at the University of Nuremberg, he completed two nationally-funded postdocs at the University of California, Irvine and Concordia University. His research examines the role of motivational and self-regulatory processes in adaptive development across the adult lifespan.
Dr. Hamm’s research in this area has been funded by the National Institutes of Health (NIH), the Canadian Institutes of Health Research (CIHR), the Social Sciences and Humanities Research Council of Canada (SSHRC), and the Deutscher Academischer Austausch Dienst (German DAAD). He has received early career awards for his research on adult development and aging from the Association for Psychological Science (APS Rising Star Award), the American Psychological Association (APA D20 Springer Award), and the Gerontological Society of America (GSA Baltes and Baltes Award).

Dyari Hama-Amin
Dyari is a Ph.D. student from the Kurdistan Region of Iraq and joined the MHAD Lab in 2025. Dyari holds a B.Sc. in Clinical Psychology from Koya University in the Kurdistan Region. His research interests sit at the intersection of developmental, health, and clinical psychology. Dyari is interested in how childhood trauma and adverse childhood experiences are linked to health, mental health, cognitive, and emotional outcomes across adulthood. His current work focuses on examining the conditions under which childhood trauma and its different forms contribute to affective dysregulation and other negative mental health outcomes later in life.

Matthew is a graduate student at North Dakota State University whose research is funded by a National Science Foundation (NSF) Graduate Research Fellowship (GRFP). His alma mater is the University of Minnesota, Morris. He is interested in motivation- and control-related factors that can protect health and wellbeing in adults, and how those factors are affected by disparities among underprivileged populations, especially regarding people with low socioeconomic status. His research is currently focused on how perceived control affected wellbeing over the course of the COVID-19 pandemic and for which sociodemographic populations these perceptions of control were most advantageous.

Laura Klepacz is a Ph.D. student who joined the MHAD lab in Summer 2023 after completing her Masters degree in psychological sciences at Northern Arizona University. Her research interests cover a wide range of topics in psychology including motivation, cognition, and development. Laura is especially interested in how individual differences between people, such as their perceptions of control, can influence cognitive performance. Her future work will investigate the motivational and self-regulatory predictors of daily cognitive performance and possible patterns in indices of cognitive variability. Laura will be pursuing research focused post-doctoral positions beginning May 2027.

Jaron completed his honors thesis in the MHAD lab in 2021. His thesis focused on the relationship between self-regulatory factors and well-being during the early stages of the COVID-19 pandemic. Using a nationally-representative sample of 300 U.S. adults, Jaron's thesis findings showed that the ability to reengage with new attainable goals after major setbacks (goal reengagement capacity) buffered against losses in mental health and well-being, particularly among adults across the lifespan who lost control over valued goals early during the pandemic. These findings were recently published in Motivation and Emotion (2022). Jaron is now a Ph.D. student at the University of Alberta.
Dr. Kelly Parker is a postdoctoral research fellow in the MHAD lab. She completed a PhD in health, nutrition, and exercise science with a dual major in gerontology at North Dakota State University in 2023. Her research centers on lifestyle factors that influence health and the aging process, especially the roles of nutrition and exercise habits. Her previous work has examined various small-steps interventions to improve diet and physical activity with the end goal of seeing intermediate to long-term behavior and health impacts related to oxidative stress reduction. Her current research is focused on the role of modifiable health behaviors (nutrition, physical activity) in protecting against age-related declines in cognitive functioning.
