Research Interests

My group has been involved in PET-related research of the CV system for more than 20 yrs. One major focus of our work is the development, validation and application of new quantitative tools to measure myocardial oxygen, glucose and lactate metabolism using PET radiotracers developed at Washington University. More recently these efforts have expanded to the pre-clinical and first in man evaluation of new PET radiopharmaceuticals designed to assess myocardial fatty acid metabolism and key cellular processes such as PPAR-alpha activation, oxidative stress, and inflammation. Germane to this application, I am a Co-PI on the Washington University PEN Program- HHSN268201000046C and work closely with others in developing new functionalized nanomaterials to image atherosclerosis.
