Jenia Vassileva, PhD
Radiation Protection Specialist
Since Jenia joined the International Atomic Energy Agency (IAEA) in 2014, she has been responsible for IAEA publications, technical and consultancy meetings and projects related to radiation protection in medicine. Jenia is also an organizer of regular IAEA webinars on radiation protection of patients, coordinator of international studies of patient doses from medical imaging procedures and has overseen development of a number of e-learnings, information and training material. She is co-author of over 100 peer reviewed articles and invited talks as well as Associate Editor of Physical Medical and reviewer for several peer reviewed journals.
Prior to 2014, Jenia was Professor of Medical Physics and Head of Department of Radiation Protection in Medical Exposure at the National Center of Radiobiology and Radiation Protection in Sofia, Bulgaria. She supervised over 40 MSc and PhD medical physics students and was involved in the postgraduate education and clinical training of medical physicists and health professionals. Jenia was involved in over 20 national, European or international research projects, a member of the Physics Subcommittee of the European Congress of Radiology 2010–2012 and its chair in 2013. She chaired two International Conferences on Radiation Protection in Medicine, 2010 and 2014 in Varna, Bulgaria, and was a guest-editor of two special issues of Radiation Protection Dosimetry. Jenia is a Past President of the Bulgarian Society of Biomedical Physics and Engineering 2012-2014.

Ryan Fisher, PhD
Chief Diagnostic Medical Physicist
I’ve spent a large portion of my career dealing with issues surrounding fluoroscopy equipment. This includes both acceptance and annual testing, as well as clinical issues surrounding image quality and patient dose. I was an author on AAPM Task Group 272, covering acceptance testing for fluoroscopy system and served as the chair for AAPM Medical Physics Practice Guideline 12.a: Fluoroscopy dose management. I’ve also been involved in updating the ACR-AAPM Technical Standard for Management of the use of Radiation in Fluoroscopic Procedures.
