is a Professor of Radiology at Rutgers New Jersey Medical School where he serves as Chief of the Division of Radiation Research. Dr. Howell’s laboratory conducts research on dosimetry and radiobiology of internal radionuclides, with emphasis on the microscopic dose distributions encountered in nuclear medicine. He also studies the capacity of vitamins and other natural agents to protect reproductive organs, bone marrow, and the gastrointestinal tract against damage caused by ionizing radiation.

These efforts have led to over 100 publications in peer-reviewed journals. Dr. Howell teaches physics to radiology residents and provides educational lectures for emergency responders in New Jersey. He has served on review panels for federal agencies including the National Institutes of Health, the U.S. Department of Energy, and other organizations. Dr. Howell is a member of the Medical Internal Radiation Dose Committee of the Society of Nuclear Medicine and Molecular Imaging, He has served on several report committees of the International Commission on Radiation Units and Measurements (ICRU) and was elected to the ICRU Main Commission in May 2014.
