POSTDOCTORAL FELLOWSHIP OPPORTUNITY in CIRCADIAN BIOLOGY and/or SLEEP MEDICINE
Division of Sleep Medicine, Brigham & Women’s Hospital, Harvard Medical School
The Division of Sleep Medicine at Brigham & Women’s Hospital (BWH)/Harvard Medical School (HMS) is seeking a candidate for a post-doctoral research fellowship position. Our clinical research program is wide-ranging and multidisciplinary, with an emphasis on circadian biology, sleep physiology, and sleep disorders medicine. Our current faculty and trainees have backgrounds in physiology, psychology, medicine, and mathematics, and the successful candidate will be encouraged to collaborate within and outside the Division as they pursue their research interests.
Current research focuses on understanding how sleep and biological rhythms change with age; the consequences of sleep deprivation and sleep restriction on sleep, waking performance/ alertness, metabolism, and social networks; individual differences in the biological timing system; the effects of light duration, intensity, wavelength, and exposure history on the biological response to light; the influence of sleep and biological rhythms on hormonal regulation; individual differences in sleep timing, sleep need, and response to sleep deprivation; developing mathematical models of sleep and circadian influences on performance and alertness; developing new statistical methods for analysis of sleep and circadian variables; and developing new techniques for electronic data capture in clinical research settings.
We seek a post-doctoral fellow to join our team who will participate in ongoing projects and develop new research initiatives. These projects will outpatient and inpatient studies of sleep and/or chronobiology conducted in the state-of-the art clinical research facilities at the BWH Center for Clinical Investigation. Candidates should have knowledge of study design and experimental statistics, grant-writing experience, a good publication record, and (preferably) experience conducting studies on human subjects. A background in sleep or chronobiological research is desirable.
BWH is a 777-bed academic medical center and teaching affiliate of Harvard Medical School, and has been named one of America’s best hospitals by the magazine US News for 16 years in a row (ranked 8th overall in 2008). BWH employs more than 12,000 people, including 3,000 physicians, fellows and residents, more than 1,000 researchers, and 2,800 nurses. Division of Sleep Medicine researchers have access to state-of-the art clinical research facilities at the Center for Clinical Investigation, part of the Harvard Catalyst [Clinical and Translational Research Center].
There is strong Institutional and Departmental commitment to research training, with many opportunities for career development and continuing education. Post-doctoral fellows are expected to take part in our institutional training program in “Sleep, Circadian and Respiratory Neurobiology” (http://sleep.med.harvard.edu). The initial appointment will be for 2 years, with possibility of annual renewals thereafter.
Interested candidates should send a letter of interest, curriculum vitae, and contact information for three references, in electronic format to:

Energy- and food-reward homeostasis is the essential component for maintaining energy balance and its disruption may lead to metabolic disorders, including obesity and diabetes. Circadian alignment, quality sleep and sleep architecture in relation to energy- and food-reward homeostasis are crucial. A reduced sleep duration, quality sleep and rapid-eye movement sleep affect substrate oxidation, leptin and ghrelin concentrations, sleeping metabolic rate, appetite, food reward, hypothalamic-pituitary-adrenal (HPA)-axis activity, and gut-peptide concentrations, enhancing a positive energy balance. Circadian misalignment affects sleep architecture and the glucose-insulin metabolism, substrate oxidation, homeostasis model assessment of insulin resistance (HOMA-IR) index, leptin concentrations and HPA-axis activity. Mood disorders such as depression occur; reduced dopaminergic neuronal signaling shows decreased food reward. A good sleep hygiene, together with circadian alignment of food intake, a regular meal frequency, and attention for protein intake or diets, contributes in curing sleep abnormalities and overweight/obesity features by preventing overeating; normalizing substrate oxidation, stress, insulin and glucose metabolism including HOMA-IR index, and leptin, GLP-1 concentrations, lipid metabolism, appetite, energy expenditure and substrate oxidation; and normalizing food reward. Synchrony between circadian and metabolic processes including meal patterns plays an important role in the regulation of energy balance and body-weight control. Additive effects of circadian alignment including meal patterns, sleep restoration, and protein diets in the treatment of overweight and obesity are suggested.
