Interested in volunteering?

Are you interested in learning more about veterinary research? Volunteering is an excellent opportunity to learn about what the research field entails, including laboratory procedures, literature review and appraisal, manuscript and grant proposal writing, and critical thinking. We currently have two volunteers in our lab and are willing to take additional people who demonstrate motivation, reliability, and above all else excitement about learning. If you are interested, please contact Dr. Stanley Marks.
