Dr. Ragsdale鈥檚 work focuses on improving the teaching and learning of neuroscience at 成人VR视频. To that end, he teaches courses for undergraduate, graduate and medical students on topics ranging from cell and molecular neuroscience to neuroanatomy and philosophy of mind. As a member of the Faculty of Medicine Faculty Development Team and in collaboration with 成人VR视频 Teaching and Learning Services, he conducts workshops and other activities for 成人VR视频 faculty on best practices in teaching, student assessment and graduate student supervision. Dr. Ragsdale is former associate director of 成人VR视频鈥檚 cross-disciplinary neuroscience graduate program, the Integrated Program in Neuroscience, a member of the 成人VR视频 Institute for Health Science Research, and serves as the Deputy University Research Integrity Officer. Dr. Ragsdale has received several teaching awards including the Faculty of Medicine Honour List for Teaching Excellence, the Canadian Association for Medical Education Certificate of Merit, and the 成人VR视频 Principal鈥檚 Prize for Excellence in Teaching.
