Radiation Oncology Physics Resident

Penn Medicine

Nice to meet you!

I am a physics resident with the Department of Radiation Oncology at Penn Medicine, University of Pennsylvania Health System.

Before moving to Philadelphia, I completed a CAMPEP Accredited Postdoctoral Certificate program at Mayo Clinic Radiation Oncology, Rochester, Minnesota. My work delivered an in-house software tool for real-time motion management during proton therapy setup and treatment. This new tool, named Wukong, provides added assurance for tumor/target localization. It has been clinically deployed at Mayo Clinic Rochester and planned for Mayo Clinic Arizona.

With a former educational background in polymer physics, I studied nanoconfined polymer electrolytes for safer rechargeable lithium-ion batteries at Brookhaven National Laboratory. To that end, I performed synchrotron X-ray scattering experiments at the Advanced Photon Source and the National Synchrotron Light Source II.

I enjoy solving scientific/quantitative problems by programming. In particular, I am fluent in Python and familiar with its scientific eco-system (i.e. NumPy, SciPy, Matplotlib, LmFit, Mayavi, scikit-image etc.). I like readable, elegant NumPy solutions, but am also comfortable with extending Python via Numba or pybind11/C++ for numerical performance boosting. For larger coding projects, I use C#/.NET (LINQ is marvelous) and strive for robustness and maintainability through good software engineering principles.
