  1. Personal Statement

I am a board-certified radiation oncologist who specializes in the treatment of gastrointestinal malignancies. I am involved with the treatment of esophageal, gastric, small intestinal, colorectal, anal, pancreaticobiliary and hepatic malignancies (primary and secondary). I oversee radiation oncology for the treatment of GI cancers at Advent Health. I have been instrumental in leading and overseeing treatment programs of Y90 for liver cancer and metastases and Lutathera for treatment of neuroendocrine carcinomas. I am the radiation oncology representative for the rectal cancer program as part of accreditation by the American College of Surgeons and Commision on Cancer.

  1. Contributions to Science

  2. Researchers at Moffitt derived a 10 gene signature that predicts for radiosensitivity of radiated tissues.  It has been extensively validated in breast, lung, GBM, rectal, esophageal, prostate, and head-neck cancers. In a comprehensive evaluation of 13,600 patients with solid tumors, a spectrum of radiosensitivity and radioresistance was observed where diseases sites like brain, pancreas, sarcoma, melanoma, and thyroid were ranked as radioresistant, while HPV-related cancers like cervical and head and neck cancers were radiosensitive. This had great potential to identify patients who will benefit from radiation and avoid treating radioresistant patients and spare them toxicity of treatment.


I was involved as a Co-Investigator in prospective trials validating the biomarker in esophageal and rectal cancers where I was responsible for the majority of enrollment and accrual. This trial was supported with a R21 grant. I was awarded a grant from the Florida Department of Health to utilize the biomarker to predict outcome for borderline resectable pancreatic cancer treated with chemoradiation. I have also presented the biomarker at SWOG on several occasions and was awarded the Young Investigator Training Course where my proposal was to incorporate the radiation biomarker in predicting response to preoperative chemoradiation for gastric cancer.  It was suggested to test SWOG samples prior to initiating a trial. I submitted a translational medicine proposal to access gastric cancer samples from the intergroup 0116 trial where resected patients were randomized to observation versus chemoradiation which was approved.  I was involved with an analysis of metastatic colorectal cancer where we show that lung metastases were more radiosensitive compared to liver metastases and confirmed with recurrence outcomes in patients with radiation treated liver or lung metastases. We also applied the RSI signature to resected pancreatic cancer who received adjuvant chemoradiation and found it to be prognostic.
