Research Interests

Being board certified in both therapeutic and diagnostic radiologic physics, I like to incorporate both disciplines in my research. I also enjoy collaborating with the Wayne State physics department in nanoparticle and quantum dot research.

My current Research Interests include, but are not limited to:

  • Motion management
  • Nanoparticle enhanced radiotherapy
  • 4D planning simulation and treatment
  • Graphene-quantum dot photon detectors
  • Low energy, high LET radiotherapy and dosimetry
  • GammaKnife radiosurgery

The projects that I mentor result in at least an AAPM meeting abstract, and occasional journal article. I find that mentoring provides a great opportunity for me to learn alongside the students.
