Dr. Mary Helen Barcellos-Hoff of Lawrence Berkeley National Laboratory (LBNL) has just been named Program Chief Scientist for DOE's Low Dose Radiation Research Program. In this capacity, Dr. Barcellos-Hoff will provide a variety of scientific and technical assistance to the Office of Biological and Environmental Research. Dr. Barcellos-Hoff's current research interests are the effects of low-dose x-rays and charged-particle radiations on stromal-epithelial interactions during mammary carcinogenesis and mechanisms by which the protein TGF-beta mediates physiological and neoplastic processes in tissues.
