Sandie Sephton, Ph.D. (Co-director)

Professor, Department of Psychological and Brain Sciences

Senior Scientist, Brown Cancer Center

Dr. Sephton’s focus is on mindfulness as a promotor of mental and physical health in the larger context of health psychology. She seeks to understand biological mediators of psychosocial effects on health, including effects of dispositional mindfulness and mindfulness meditation-based interventions. Her contributions include data showing the diurnal cortisol rhythm is prognostic for early breast and lung cancer mortality. Her research has provided evidence that childhood trauma may result in adult neuroendocrine dysfunction, and that social support, emotional expression, and existential or spiritual coping styles may protect normal endocrine and immune function in individuals who have experienced trauma, cancer, or chronic illness. Dr. Sephton’s research group is co-directed by Dr. Paul Salmon (Psychology). The Mindfulness and Biobehavioral Research Laboratory has demonstrated in a randomized clinical trial that mindfulness meditation relieves depressive symptoms among women with fibromyalgia. Current research is exploring psychoneuroimmune outcomes of meditation training in undergraduate students and investigating circadian disruption as a mediator of psychosocial effects in cancer progression.




Paul Salmon, Ph.D. (Co-Director)

Associate Professor of Clinical Psychology
Department of Psychological and Brain Sciences
University of Louisville

I joined the faculty in the Department of Psychological and Brain Sciences in 1976 after graduating from DePaul University with a Ph.D. degree in Clinical Psychology, More recently, I obtained an M.S. degree in Exercise Physiology from the University of Lousiville. I am a licensed psychologist, and and also certified as both a Health Fitness Specialist by the American College of Sports Medicine and a yoga instructor through the Yoga Alliance (RYT/200 level). In collaboration with Dr. Sephton, I co-direct the BioBehavioral Laboratory and Mindfulness Studies Program here at the University of Louisville. My research, clinical, and teaching interests center on mindfulness, in a variety of contexts including stress management, exercise, clinical practice, and environmental sustainability. I derive enormous satisfaction from collaborating with Dr. Sephton and a wonderful team of gifted and enthusiastic undergraduate and graduate students who share a common interest in mindfulness. The result of this fruitful collaboration has been a steady flow of research publications, conference presentations, and clinical initiatives over the years that continues to grow and flourish. Currently, I am finishing work on a text for clinical practitioners, Mindfulness in Motion.




Elizabeth Cash, Ph.D. (Co-Director)

Dr. Cash is the Director of the Research Program and Head & Neck Cancer Outcomes Research Program for the Department of Otolaryngology-HNS & Communicative Disorders. Her graduate training in Clinical Psychology and current role in multidisciplinary medical clinics informs her investigation into biological and behavioral correlates of cancer
progression. Her research program is based on a model of psychoneuroendocrine and immune effects in cancer progression (Eismann, Lush & Sephton 2010). Her research assesses relationships between psychological factors, circadian rhythms measured via actigraphy, endocrine rhythms measured via salivary cortisol, systemic inflammatory processes, and biomarkers of tumor progression, response to treatment, and prognosis among patients diagnosed with cancer.

Lauren Zimmaro

Lauren Zimmaro is a current graduate student in the clinical psychology doctoral program at the University of Louisville.  She completed her undergraduate degree at Wake Forest University with a major in psychology and a minor in biology.  Her main research focus is the intersection of positive psychology with health psychology, with particular attention to mindfulness-based interventions in patients with chronic illnesses.  She is interested in the cognitive, emotional, and physiological processes that are linked to positive coping mechanisms and health outcomes in the context of disease.  Her work in the Mindfulness and Biobehavioral lab will begin with a concentration on patients diagnosed with cancer, and she is looking forward to her research and clinical work in the University Hospital.



 Chelsea Siwik

Chelsea Siwik is a clinical psychology graduate student in the doctoral program at the University of Louisville. She completed her undergraduate degrees at the University of Wisconsin, Madison with a major in both Psychology and Spanish. Chelsea’s main research interests focus on the bidirectional relationships between biomarkers of stress, immunity, genetic variants, and psychological comorbidities among patients with chronic medical illness. She is particularly interested in the cognitive and physiological processes that are linked to chronic stress and their contributions to progression of disease. Her work in the Mindfulness and Biobehavioral Health lab began with examining the impact of different coping styles on psychological and physiological stress outcomes among women diagnosed with gynecological cancer. Her future efforts aim to focus on clarifying the relationships between chronic stress, psychological comorbidities, immune imbalance, and medical outcomes among cancer patients.


Melissa Ellsworth

Melissa Ellsworth is a current graduate student in the clinical psychology doctoral program at the University of Louisville.  She completed her undergraduate degree at University of Maryland with a major in psychology.  Her main research focus is the connection between emotion, stress and physical health with a focus on trauma and chronic pain, and how mindfulness-based interventions can be used to improve health outcomes.  She is also interested in how mindfulness-based interventions can be extended to community-health settings.  In line with her interests, she will be leading a mindfulness-based relapse prevention program for individuals in recovery from addiction at Wayside Christian Mission in downtown Louisville, a community health-based shelter and training program for homeless individuals.  Her future plans include continuing research in the application of mindfulness-based interventions for mental and physical health outcomes and how to make these interventions more accessible to community health settings.


 René Bayley-Veloso

René Bayley-Veloso is a doctoral candidate in the clinical psychology program at the University of Louisville. She graduated from the University of Illinois at Chicago with a B.A. in psychology and began graduate work in 2012, receiving her M.A. from UofL in December of 2014. Her research interests center on three interrelated themes: 1) mindfulness as a clinical intervention; 2) the impact of trauma history on cancer outcomes; and 3) examining the potential role of mindfulness in buffering stress associated with the cancer experience. Her dissertation is examining the intersection of trauma, mindfulness and health-related quality of life in a sample of lung cancer patients with the aim of understanding both the vulnerability and protective factors that may impact health-related quality of life in this underserved and under-studied sample. René has a strong interest in working with the military, and has worked with active duty Army at Fort Knox for two years. She plans to combine her research and clinical interests during her predoctoral internship at the Dallas VA hospital in July of 2016.
