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. Dr. Grondin currently holds the academic position of Associate Professor of Neuroscience at the University of Kentucky College of Medicine.
He also serves as Director for the University of Kentucky Good Research Practices (GRP) Resource Center. The GRP Resource Center was created to support research conducted in laboratories and research core facilities at the University of Kentucky by promoting data reproducibility, rigor and transparency. The GRP Resource Center offers training workshops to students, faculty and staff, which include study planning and conduct through use of protocols and standard operating procedures, logs of use/maintenance and calibration for key equipment as well as data retention and reporting principles. Additionally, Dr. Grondin serves as scientific member on the University of Kentucky Institutional Animal Care and Use Committee (IACUC).
The Grondin laboratory focuses on developping new treatment strategies for Huntington’s disease and Parkinson’s disease. One promising treatment approach is to use a technique known as RNA interference to silence the expression of genes of interest with the goal of potentially slowing or preventing disease progression. This can be acheived by using either adeno-associated virus (AAV) vectors carrying short hairpin ribonucleic acid (shRNA) or small interfering RNA (siRNA) constructs designed to reduce production of target-specific proteins, such as huntingtin and alpha-synuclein. These compounds are delivered directly into brain regions affected by the disease process. These potentially disease-modifying therapies are studied in vertebrate animals and the effects of these experimental treatments are evaluated using a variety of methods, including behavioral, neurochemical and neuropathological methods.
