Karlene Cimprich, PhD, has been promoted to associate professor of chemical and systems biology, as of Dec. 1. Her lab is focused on understanding the mechanism that the cell uses to maintain genomic stability, with an emphasis on DNA damage checkpoints. Loss of this checkpoint response is a hallmark of cancer cells and is one of the early steps in the development of cancer.

Ralph Horwitz, MD, has been appointed professor of medicine, as of Dec. 1. He will also serve as chair of the Department of Medicine. Prior to joining Stanford, Horwitz was medical school dean at Case Western Reserve University in Cleveland. He has investigated the link between estrogen and the risk of breast and uterine cancer; the relationship between phenylpropanolamine (which can be found in many cold remedies and appetite suppressants) and brain hemorrhage in young adults, and the correlation between coffee consumption and bladder cancer.

Maurice Ohayon, MD, PhD, has been promoted to professor (research) of psychiatry and behavioral sciences, as of Dec. 1. Much of Ohayon's research focuses on sleep and psychiatric disorders. He has documented sleep habits and sleep patterns of the general population, and how sleep disorders are identified and treated. Additionally, he has studied risk factors of post-traumatic stress disorder, social phobia, panic disorder and generalized anxiety disorder.

Norbert Pelc, ScD, professor of radiology and of bioengineering, has been elected to the College of Fellows of the American Institute for Medical and Biological Engineering. Membership is awarded to "leaders in the field who have distinguished themselves through their contributions in research, industrial practice and/or education." Pelc's career in biomedical imaging has spanned nearly three decades, during which he contributed to most diagnostic modalities, including computed tomography, digital X-ray imaging, positron emission tomography, single photon emission computed tomography and magnetic resonance imaging. The award will be presented at the institute's annual meeting in March.

David Relman, MD, associate professor of medicine and of microbiology and immunology, received one of the 2006 Distinguished Clinical Scientist Awards, presented by the Doris Duke Charitable Foundation. Relman will receive $1.5 million to use over five to seven years to support the translation of the latest scientific advances into clinical applications that will improve human health.

Kuldev Singh, MD, professor of ophthalmology, is the recipient of the 2006 American Academy of Ophthalmology Secretariat Award. The award recognizes ophthalmologists for special contributions to the academy and to the field, and was developed to increase opportunities for ophthalmologists to be recognized for contributions that are outside of the scope of the current achievement award program.

Greg Zaharchuk, MD, PhD, has been appointed assistant professor of radiology, as of Dec. 1. His research interests include imaging of cerebral hemodynamics with MRI and CT; noninvasive oxygenation measurement with MRI; and clinical imaging of cerebrovascular disease.
