In its state-of-the-art, small animal imaging facility, the Small Animal Imaging Center Shared Resource (SAISR) provides expertise and training to the OSUCCC–James members as well as to other academic and commercial institutions. 

SAISR Directors: Kimerly A. Powell, PhD

MRI/US Imaging Research Scientist: Anna Bratasz, PhD

Inveon™ microCT/PET/SPECT Manager: Michelle Carlton

Kimerly A. Powell, PhD, is an assistant professor of Biomedical Informatics.

With more than 15 years of experience in developing image post-processing techniques for quantitative image analysis of microscopy, pre-clinical and clinical images, Dr. Powell also focuses on developing image post-processing techniques for quantitative image analysis of cancer, cardiac and musculoskeletal applications.

She is particularly interested in developing novel image post-processing techniques for high-resolution microscopy and small animal in vivo micro-imaging technologies.
