Dr. James Olcese
Professor of Biomedical Sciences, Neuroscience & Molecular Biophysics
- The Olcese lab investigates the role of cellular circadian clocks and hormonal outputs of the central circadian clock on neurological and physiological events, including sleep, cognitive performance (learning and memory), and the timing of human labor. In particular, we study the role of sleep and the brain hormone melatonin on cognitive changes that accompany aging, especially in the context of Alzheimer’s dementia. In addition, we are running clinical trials on the impact of blue light exposure on uterine contractions during late pregnancy with the goal of developing a novel medical device to reduce the risk of preterm labor.
- Current Research
- Our studies include experiments on the effects of melatonin on neuronal cells in culture as well as effects of melatonin on the development of Alzheimer-related neuropathology in transgenic mice at both the molecular and behavioral levels. Our studies in reproductive biology involve both molecular/cellular analyses of human myometrial smooth muscle cells in culture as well as trials with pregnant human volunteers.
