Biography and Education
Education
Dr. Richard C. Grondin, Ph.D., graduated in December 1997 from Laval University College of Medicine in Quebec City (Canada) with a doctorate degree in Neurobiology. He then completed a 3-year postdoctoral fellowship in Anatomy and Neurobiology at the University of Kentucky from 1998 - 2000. Dr. Grondin currently holds the academic position of Professor of Neuroscience at the University of Kentucky College of Medicine.
Research
The Grondin laboratory is currently funded by NIH-NINDS and the Cure Huntington's Disease Initiative (CHDI) to conduct long-term tolerability studies in non-human primates administered adeno-associated virus (AAV) vectors carrying short hairpin ribonucleic acid (shRNA) designed to lower wildtype huntingtin expression in the brain. This work will inform ongoing and future clinical trials seeking to use non-allele specific huntingtin lowering approaches in Huntington's disease patients.
