Personal profile
Research interests
Developing quantitative PET techniques, especially for the human brain and in preclinical models with an emphasis on the underlying physics. We have pioneered multiple new types of medical imaging instrumentation and data processing algorithms. In particular, we developed the RatCAP conscious animal PET scanner and one of the first simultaneous PET/MRI systems for rodents.
