In addition, Elizabeth Nichols, MD, Associate Professor and Clinical Director, and Zeljko Vujaskovic, MD, PhD, Professor and Director of the DTRS, have been named Vice Chairs in the Department.

Dr. Jackson to Receive UMSOM Faculty’s Highest Honor

Dr. Jackson will become the Marlene and Stewart Greenebaum Endowed Professor in Radiation Oncology, the 85th such Endowed Professorship at the UMSOM. This honor recognizes Dr. Jackson to be among the most distinguished faculty members at the School of Medicine. This endowed professorship has been made possible by the continued generosity of the Greenebaum Family Foundation.

Michael GreenebaumSpeaking on behalf of his family, Michael Greenebaum, President of Greenebaum Enterprises and a member of the UMSOM Board of Visitors, said, “We are so pleased that Dr. Jackson is receiving the Marlene & Stewart Greenebaum Professorship in Radiation Oncology. Our family continues to support the University of Maryland School of Medicine, and this professorship will provide vital funding for Dr. Jackson’s outstanding research in the fight against cancer.”

Mohan Suntha, MDA formal investiture ceremony to honor Dr. Jackson on the receipt of this recognition will be scheduled for a future date. Once invested, she will join Mohan Suntha, MD, MBA, who is also a Marlene and Stewart Greenebaum Endowed Professor of Radiation Oncology. He is also the President and CEO of the University of Maryland Medical System (UMMS). “For the past three decades, the Greenebaum family have been tremendous supporters of our collective mission,” said Dr. Suntha. “This recognition of Dr. Jackson’s track record of academic excellence is the latest way we are paying tribute to the family’s aspirations for our institution.”

Kevin J. Cullen, MD, the Marlene and Stewart Greenebaum Distinguished Professor of Oncology at UMSOM, and director of the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center (UMGCCC), added, “I congratulate Dr. Jackson on her appointment as a Greenebaum Endowed Professor. The tremendous support of the Greenebaum family is felt throughout the Cancer Center and across this campus. These professorships have done much to promote excellence in research and to elevate the status of the Department of Radiation Oncology and the UMGCCC.”

Dr. Jackson, who joined the Department of Radiation Oncology in 2012, is a dynamic and outstanding researcher and educator who has brought international attention and significant research and funding to the University of Maryland School of Medicine in the research area of radiation countermeasures. She has also proven to be a leader in laboratory development and management, working with Dr. Vujaskovic to create new models for extramural support. DTRS now has a funding portfolio of more than $45 million, including significant support from the Biomedical Advanced Research and Development Authority (BARDA), the National Institute of Allergy and Infectious Diseases (NIAID), and industry.

E. Albert Reece, MD, PhD, MBA“Dr. Jackson is an exceptionally talented faculty leader who is increasingly recognized as a national and international leader for her research and discovery in developing medical countermeasures against radiation sickness,” said Dean Reece, who is also Executive Vice President for Medical Affairs, UM Baltimore, and the John Z. and Akiko K. Bowers Distinguished Professor.  “In recognition of the impact Dr. Jackson has as an academic leader in her field, she is most deserving of this high honor.”

As Director of the Medical Countermeasures Program in Radiation Oncology, Dr. Jackson has strategically developed the organizational structure, recruited talent, and secured funding to build the reputation of the program into the premier site for medical countermeasure research on the national and international stages. “Dr. Jackson is an internationally recognized rising superstar in the field of Radiation Biology who has brought tremendous recognition to both our department and School of Medicine,” said Dr. Regine. “She will no doubt soar to even greater heights of research success as a Marlene and Stewart Greenebaum Endowed Professor, which will ultimately improve the lives of cancer patients around the world.”

Most recently, Dr. Jackson wrote and coordinated submission of the proposal that led to her department’s designation as a NIAID/NIH Center for Medical Countermeasures against Radiation (an award of more than $12 million plus options), as well as supplemental funds from BARDA (>$7m) to continue the Division’s critical efforts towards development of medical countermeasures against acute radiation sickness. “I am both humbled and honored by this appointment,” said Dr. Jackson. “In no small measure, this recognition springs from the support and opportunities that Dean Reece and Dr. Regine have given me over the years. Looking ahead, I will employ this professorship thoughtfully and purposefully in honoring the Greenebaum family’s commitment to improve the lives of cancer patients.”

New Department Leadership Structure at Time of Rapid Growth

In making the announcements, Dr. Regine noted that the appointments come at a time of continued geographic and technologic expansion in department clinical activities and remarkable growth in radiation-focused research.

William F. Regine, MD, FACR, FACROWhen I came to Maryland 18 years ago, the department had 23 faculty members and 113 total staff at three centers,” said Dr. Regine, who is also the Isadore and Fannie Foxman Schneider Chair in Radiation Oncology and Executive Director of the Maryland Proton Treatment Center (MPTC). “Today, we have more than 78 faculty members and 260 staff at six centers serving patients with cancer throughout the state of Maryland. As we continue to grow, our leadership structure must evolve as well. Dr. Nichols and Dr. Vujaskovic will work directly with me in their respective vice-chair roles to define new leadership positions, maintain consistently high quality care across our multiple sites, and create new opportunities for research success for our faculty, trainees and patients.”

Elizabeth Nichols, MDDr. Nichols, who will become Vice Chair for Clinical Operations in the Department, is an Associate Professor in the Department of Radiation Oncology, where she serves as Medical Director, and is the department’s Clinical Director across its multiple sites. She was the Clinical Lead for implementation of the GammaPod stereotactic breast program, for which she now directs patient treatment and research, and is also the Director of the international GammaPod Research Consortium. A UMSOM graduate, Dr. Nichols has been named one of the “25 Women to Watch” by The Baltimore Sun (2019) and as “Physician of the Year” (2020) by the Daily Record.

Zeljko Vujaskovic, MD, PhDDr. Vujaskovic, who will become Vice Chair for Research in the Department, is an internationally recognized NIH-funded radiation oncologist/biologist whose more than 30-year career has been defined by transdisciplinary research that bridges the gap between basic science and the clinic research to ultimately improve outcomes and long-term quality of life among cancer patients. Since coming to the UMSOM in 2012, his division’s research has been continuously supported by the National Institutes of Health, the Biomedical Advanced Research and Development Authority (BARDA), and other federal agencies, as well as industry sponsors. Most recently, he received a five-year, $12,239,361 U19 award from the National Institute of Allergy and Infectious Diseases (NIAID) to establish an NIAID Center for Medical Countermeasures Against Radiation at the  UMSOM.

On July 1, Dr. Regine assumed the position of President of the Medical Staff for the University of Maryland Medical Center (UMMC), where he serves as a member and chair of the UMMC Medical Executive Committee, and as an ex officio member of all other Medical Staff committees.

With increasing responsibilities beyond the department, I am looking forward to sharing day-to-day and long-term management and strategic planning with Dr. Nichols and Dr. Vujaskovic,” said Dr. Regine. “They have already established extraordinary track records of leadership and accomplishment in our department and at UMSOM. Together, we will work to meet the challenges and optimize the rewards that come with fulfilling our missions of patient care, research, education, and community outreach in a rapidly changing environment.”
