Harry Roy

Professor, Biological Sciences

The Roy laboratory discovered the role of ATP in the action of the chloroplast molecular chaperone, a homologue of GroEL, and worked out many of the details of the assembly of the key photosynthetic enzyme, ribulose bisphosphate carboxylase/oxygenase. The field of molecular chaperones has continued to expand, reaching into many areas of biochemistry and medicine, including the presentation of antigens in the immune system. Since 2005, the Roy laboratory has been closed. Professor Roy has collaborated with Drs. Alan Day and Robert L Dean of the University of Western Ontario on producing an update of their Visual Genetics software package. Professor Roy and his colleagues at Rensselaer have conducted research on educational methods. Their work has focused on demonstrating the effectiveness of studio teaching techniques. The metric used to monitor this is to assess the gain in learning , which is the proportion of what the students do not know that they learn during the semester, as determined by objective pre- and post-course testing.
