Research Interests

Dr. Borak's interests are principally related to radiation physics and dosimetry. This involves measurements as well as computational methods for dose assessment. Students involved in these projects usually have a background in physics or engineering and are expected to develop additional skills in mathematics and statistics through course work and practical experience.

Many of the experiments are performed at national laboratories or specialized facilities operated by the Department of Energy and the National Institute of Radiological Sciences in Japan. A brief description of some of the projects and recent publications are listed under "Projects".
