A. Personal Statement
The current grant application proposes the development of a learning health system in the oncology setting.
Efficacy of this system will be demonstrated through modeling efforts to explore radiation-induced normal
tissue complications, but overall design of the system will enable a broad spectrum of scientific studies. Having
a background in medical physics, my education and training has prepared me for a critical role in this project,
which is to bridge the expertise of our computer science, statistics, and physician colleagues.
With respect to technical expertise, my medical physics research projects as a graduate student and
postdoctoral fellow have required substantial programming and statistical skills. I am able to contribute to
complex programming projects, utilize source code repositories, and benefit from other development
resources. This experience includes object-oriented and modular programming practices that will be essential
in creating a generalized learning health system.
With respect to clinical experience, medical physics training requires knowledge of human anatomy, cancer
(radio-)biology, and the basis of treatment decisions. This includes didactic training in normal tissue dose
tolerance limits and the underlying normal tissue complication probability modeling. I have spent over a year at
Johns Hopkins developing an interface for dose-toxicity modeling based on dose-volume histogram curves.
Results have been effectively communicated to physicians and other patient care providers.
Having such a diversity of expertise within our group, efforts will be maximized only through coordination.
Along with PI Dr. Todd McNutt, our leadership and vision will be pivotal to progress on this project.
