Dr. Jimmy Fenn, Professor Emeritus in Radiation Oncology, Medical University of South Carolina, Charleston, South Carolina, was a Fellow of the American Association of Physicists in Medicine (AAPM), the American College of Medical Physics (ACMP), and the American College of Radiology (ACR). Jimmy's career in medical physics spanned nearly four decades. Much of that time was spent at the Medical University of South Carolina where he served as the head of radiation oncology physics from the early 1980's to his recent retirement in 1998. Jimmy received his bachelor's degree in physics in 1965 from Lincoln Memorial University in Tennessee and began his career in medical physics shortly thereafter as a radiation physicist in the Department of Radiology at Emory University School of Medicine. During that time he also continued his graduate studies at Emory University, receiving his master's degree in radiological physics in 1967. He continued his graduate studies interspersed with his medical physics career and in 1980 he received his doctoral degree in physics from the Georgia Institute of Technology. In 1977, Jimmy was certified in Radiological Physics by the American Board of Radiology (ABR), and in 1990 he was certified in Radiation Oncology Physics by the American Board of Medical Physics (ABMP). Jimmy's efforts in supporting board certification for medical physicists are well known. He never wavered in his belief of the importance of board certification and gave unselfishly of his time serving both the ABR and the ABMP.

Jimmy was a highly respected clinical medical physicist. He held several leadership positions in medical physics serving as President of the Southeastern Chapter of the AAPM in 1972, and as an elected member of the AAPM Board of Directors from 1985 to 1988. He also gave unselfishly of his time serving on many AAPM committees and councils including the Professional Council and the Science Council. Jimmy was also very active in the ACMP, being elected to the Board of Chancellors in 1982–83. During that time, he was elected as Secretary for the ACMP. Over the next decade he continued his strong support in promoting ACMP's efforts regarding medical physics professional issues, and in 1991 was elected Chairman of the Board of Chancellors. In addition, he was also active in the ACR serving on the Radiation Physics Committee in the ACR Commission on Radiation Therapy during the years 1981 to 1988.

Throughout his career, Jimmy was strongly committed to the teaching of physician residents in radiology and radiation oncology, dosimetrists, and the mentoring of young physicists entering the field of medical physics. One of his greatest strengths was his ability to communicate effectively with trainees and shed light on even the most complicated subjects by using straightforward, clinically relevant examples.

Jimmy's untiring efforts and contributions to medical physics were recognized by his peers and radiation oncology colleagues as evidenced by his previously mentioned selection to Fellow status in all three organizations, AAPM, ACMP, and ACR. In 1999, Jimmy received the ACMP Marvin M.D. Williams Professional Achievement Award, its highest honor, recognizing his many contributions to the field.

Jimmy passed away on September 28, 2000 at the age of 62. He died of complications arising from pneumonia. For all of Jimmy Fenn's medical physics accomplishments, those of us who knew him well know that his real passion for living stemmed from his relationships with people and his love of the outdoors, particularly fishing. He left behind his beloved wife, Debbie, his two stepsons, Vincent and Cole, his son, Daniel and two daughters, Nancy Anne and Beth, his close friends in Charleston, and his many friends throughout the world. His efforts in promoting the profession of medical physics are well known, and will be long remembered. Equally well known is the way he conducted himself throughout his career, always being a man of high principle and always a true gentleman. He truly was a credit to our profession. He will be greatly missed.

George W. Sherouse, PhD, FAAPM was a "force of nature" in the world of medical physics, to quote one AAPM President. Those who worked with him would likely readily agree that he also made an impact on many people in our field. Dr. Sherouse was an innovator in therapy physics, developing the first modern GUI-based 3D treatment planning system. He spent much of his career working in the states that comprise the SEAAPM and served our chapter through the presidential cycle from 1995-1998. One of his proudest professional accomplishments was the creation of a medical physics residency program at Vassar Brothers Medical Center in New York. This program was one of the first community practice-based residencies designed to provide formal clinical training of medical physicists. Dr. Sherouse was intensely focused on the quality of medical physics practice and how to pass on this knowledge to future generations of medical physicists. Through one-on-one mentorship, AAPM committee commitments, and involvement in residency programs, Dr. Sherouse helped shape safe practice in medical physics. George would say "It's our job to keep it on the rails."

The SEAAPM Executive Committee agreed, and wanted to see Dr. Sherouse's passion for medical physics education continue. Following his passing in January of 2022, SEAAPM leaders voted to establish the George Sherouse Investigator Award as a recognition and travel award to a recipient in honor of Dr. Sherouse's enthusiastic support for students and trainees. The award is for current trainees or early-career medical physicists who submit an abstract for an oral presentation to the SEAAPM Annual Scientific Meeting and are selected as the winner of a competition to recognize the best work in any field of medical physics.

Note: This award is for special recognition beyond that of submissions to the meeting's General Trainee session and has specific rules outlined below. Abstracts will be blinded to the panel of judges. Recognition will come in the form of an honorarium for travel, presentation in a special session of the SEAAPM Annual Scientific Meeting, promotion on the SEAAPM website and social media channels and a plaque to the winner!

A panel of judges will score the oral presentations according to criteria that includes scientific merit, originality, and organization/presentation of the material.

  • A substantial part of the work reported in the abstract must have occurred within institutions or facilitates located in the SEAAPM geographic region.
  • The Abstract is limited to 300 words and should be structured as Purpose, Methods, Results, and Conclusion.
  • Supporting Document is REQUIRED and must not exceed 2 pages in length.
  • No part of the Abstract or Supporting Document should contain identifying information such as title, author names, affiliations, institutions, etc. Submissions containing such information may be rejected without review.
  • All abstracts submitted to the Early-Career Investigator Symposium Award that are NOT selected for as the winner, will be automatically considered for an oral presentation at the SEAAPM Annual Meeting in the General or General Trainee Session.

Award: A $1,000 honorarium to cover transportation to the meeting, presentation in a special session of the SEAAPM Annual Scientific Meeting, and a plaque to the winner.
