    Meet our new technologist

    Autumn Craig started Monday, April 18 as our part-time technologist at the MRI Research Facility. This addition to our research staff will allow us to expand our hours of operation and to accommodate a greater number of evening and weekend scanner requests. Autumn has worked as a technologist in the Department of Radiology for the previous 8 years, and has extensive experience conducting fMRI research scans as a backup technologist for our facility. Her experience and flexibility will play an important role in the success of our young imaging facility, and will be especially valuable as we begin to establish our ultra-high field 7T program.
