Assistant Professor of Health Psychology
Director of the PNE Lab
University of California, Merced
Jitske Tiemensma received her Ph.D. from Leiden University (The Netherlands) in Medical Science and joined University of California Merced as an Assistant Professor in 2012. She is a psychoneuroendocrinology researcher interested in the biological and psychosocial components of acute and chronic stress in humans. Specifically, she is interested in fluctuations in biomarkers (stress hormones, heart rate, and blood pressure) due to specific stressors and if/how these fluctuations can be influenced. Furthermore, Dr. Tiemensma is interested in how people perceive and cope with stressors. The second line of research in her lab at UC Merced involves people’s perceptions about their illness (i.e. a potential chronic stressor) and their subsequent coping strategies. Work in this line of research is driven by the common sense model of self-regulation. Within this line of research, her main research trajectory focuses on the psychosocial consequences of endocrine disorders such as adrenal insufficiency and hormone-secreting pituitary adenomas.
