I am an attending physicist and Head of Brachytherapy Physics at Memorial Sloan Kettering, and a Professor of Physics in Radiology at Weill Cornell Medical College. I also have a faculty appointment at Columbia University, where I teach in the graduate program in Medical Physics.

My special interests include the planning and delivery of brachytherapy (the placement of radioactive “seeds” inside a tumor), radiation oncology, microdosimetry, the biological effects of ionizing radiation, and biostatistics.

I received the Edelman Award for Achievement in Operations Research — presented by the Institute for Operations Research and the Management Sciences — for my paper entitled “Operations Research Answers to Cancer Therapeutics.” Working with Dr. Eva K. Lee at the Georgia Institute of Technology in Atlanta.

I devised sophisticated optimization modeling and computational techniques to implement an intra-operative three-dimensional treatment planning system for brachytherapy. This work has been shown to improve the survival rate of patients with prostate cancer, reduce treatment side effects, and lower healthcare costs.
