close windowRichard Day received his Ph.D. in 1987 from the Department of Pharmacology at the University of Rochester. Following postgraduate training at the University of Iowa with Dr. Richard Maurer, he joined the faculty of the Division of Endocrinology and Metabolism in the Department of Medicine at the University of Virginia. Dr. Day's research is defining the molecular mechanisms that regulate the expression of hormones in certain differentiated cell-types of the anterior pituitary. His studies using the color variants of GFP to label different nuclear proteins show that the assembly of cooperating factors at particular subnuclear sites is an important component in the control of cell-specific gene expression. He is using the approach of FRET microscopy to study these protein-protein interactions in the nucleus of the living cell.
