My research focuses on the implementation and continued development of patient-specific internal dosimetry for targeted molecular radiotherapy with theranostic radiopharmaceuticals. We collaborate with a number of radiation oncologists in an effort to develop new cancer therapies utilizing the synergistic properties of molecular radiotherapy with conventional external beam radiotherapy and immunotherapies.

Future plans:

Upon completion of my PhD, I intend to apply for a residency position in pursuit of ABR certification in therapeutic and nuclear medical physics. I hope to establish myself as a clinical medical physicist and continue to support research efforts to bring more safe and effective treatment planning to the world of molecular radiotherapy.

When not in the lab:

You can usually find me running around the isthmus and exploring new events around the city. I enjoy working out and spending what time I can in the outdoors through hiking, travel, or whatever excuse the season allows for. I also serve as a Graduate Student Representative in the Department of Medical Physics where I help facilitate communication between students and faculty as well as coordinate and organize department events.
