A physicist who applied radiobiology to the comparison of radiation therapy schedules. His work on the linear-quadratic radiobiology model explains why equal total absorbed doses can produce different biological effects when delivered in different-sized fractions. The model separates contributions linear and quadratic in the dose per fraction, while a comparison of schedules must also consider tissue recovery and proliferation over time. This work helped turn a statement of delivered energy into a model of biological response.[ref]
