Harry Roy

Professor of Biology

Education and Training

A.B., Sc. M., Brown University
Ph.D., The Johns Hopkins University
Postdoctoral Appointment, Cornell University
Senior Research Fellow, Harvard University 

Dr. Roy received his Ph.D. with Van Moudrianakis at The Johns Hopkins University, performed his postdoctoral studies with André Jagendorf at Cornell University, and joined Rensselaer in 1976. He worked with Lawrence Bogorad during a sabbatical at Harvard in 1983-1984.

Dr. Roy is a member of the American Society of Plant Biologists, and has served on the editorial board of the Journal of Biological Chemistry.

Research Interests

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 a Macintosh version and an update of their Visual Genetics software package. An online Authorware version of this that plays on Windows can be found by clicking on the link.

Professor Roy and his colleagues at Rensselaer have conducted research on educational methods. Their work has focused on demonstrating the effectiveness of innovative teaching methods. The metric used to monitor this is to assess the gain in learning <g>, 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.
