I have been working as a Clinical Medical Physicist for nearly 20 years with an American Board of Radiology Certification in Therapeutic Medical Physics for over 10 years. My training and practical experience encompasses shielding calculations, commissioning new technology and programs such as SRS and SBRT, quality assurance and treatment planning for complex and simple techniques in addition to fully supporting the clinic ensuring the best standard of care for our patients. I also have experience in HDR brachytherapy mostly for gynecological applications. Currently I provide Therapeutic Physics services for UPMC’s Radiation Oncology Department covering the South/ West Region (Beaver, Moon, St. Clair, Uniontown, Washington).
