Welcome to the home of the Pennsylvania-Ohio-West Virginia Chapter of AAPM. We hold an annual meeting, a Spring Annual Meeting and support our regional trainees with MedPhys Slam Competitions.
Thanks for visiting our website, and please don’t hesitate to email us if you’d like more information about membership, becoming a sponsor, or attending one of our functions!
The Pennsylvania-Ohio-West Virginia Chapter Officers consist of an acting President, President-Elect, Past-President, Secretary, Secretary-Elect, Treasurer, and Chapter Representative to the Board.
2023 Officers

Dr. Peter Sandwall, PhD DABR is a clinical therapeutic physicist at OhioHealth, Mansfield Hospital. A graduate of West Virginia Wesleyan College and the University of Cincinnati, Dr. Sandwall is an adjunct at North Central State College and President of a small consulting firm, Precision Physics.
An active volunteer, Dr. Sandwall is a board member of Radiating Hope and has served multiple organizations including the Boy Scouts of America, Health Physics Society, Rayos Contra Cancer, and Rotary International. Dr. Sandwall previously served as President of the Ohio River Valley Chapter of the AAPM.

I serve as a clinical therapeutic physicist at UPMC, St. Clair Hospital. I earned my BSc in Physics from King Saud University, Riyadh, Saudi Arabia. My first exposure to the field was at King Faisal Specialist Hospital and Research Center in Riyadh. I received my MSc in medical physics from Duke University, then my PhD in Nanoscale sciences from SUNY Albany. I am an active volunteer with MPWB and Rayos Contra Cancer.

I have been practicing medical physicist for the last 30+ years. I am originally from Trinidad and Tobago and have a myriad of experience both in the US and internationally. Most of my work has been as a clinical radiation oncology physicist. I have worked for the United Nations agency – the Pan American Health Organization (PAHO)/ World Health Organization (WHO) as a consultant physicist in its Radiological Health Program. I was part of the initial group of physicists that formed the Trinidad and Tobago Medical Physics Organization in 1993. I served as its president from 1996 - 1999. We were able to gain membership to the International Medical Physics Organization. Currently, I am a medical physicist with UMPC Hillman Cancer Center at its Northwest Campus. I also currently serve on the Global Needs Assessment Committee and the Global Representatives Sub-Committee under the International Council of AAPM.

Susan Kost is currently a medical physicist at the Cleveland Clinic Akron General Hospital. She joined the medical physics staff after completing residency in therapy physics at main campus that included a third year of research mainly focused on surface guided radiotherapy for the treatment of breast cancer.
Susan is clinically-focused and passionate about Medical Physics 3.0. She views her practice not as a mere technical exercise, but as a means to enhance the patient experience through quality and safety. Part of that approach is to “be seen” by the patient and educate them on the role physicists have in their treatment. She also drives innovation through her research on Monte Carlo simulation for internal dosimetry.
She has been active in the Penn-Ohio-West Virginia chapter of the AAPM since the beginning of her residency. She has attended both the annual fall symposiums and spring meetings and presented her research at the young investigators symposium.

Abby received her BS in Nuclear Engineering from Missouri University of Science & Technology (Rolla, MO) in 2017. She earned her MS in Medical Physics from Vanderbilt University (Nashville, TN) in 2019 and completed a CAMPEP-accredited medical physics residency at Vanderbilt University Medical Center (Nashville, TN) in 2021. She then joined the team at Allegheny Health Network as a clinical medical physicist in 2021 and became board-certified in Therapeutic Medical Physics in 2022. She is currently a Professional Ph.D. student through University of Florida.
Her main interests include adaptive radiotherapy, brachytherapy, process improvement, and treatment planning. She is an Instructor of Radiological Science at Drexel University College of Medicine and an active member of the American Association of Physicists in Medicine (AAPM) both at the national level and with the local Penn-Ohio chapter.

Rajesh is the owner of Makshi Physics Consulting Services providing diagnostic medical physics and radiation safety services in four states: Ohio, Pennsylvania, New York, and Texas. He is double boarded with ABR certifications in Diagnostic Radiological Physics and Therapeutic Radiological Physics. Prior to starting his own business, Rajesh has worked as a medical physicist at University Hospitals, Procure Proton Therapy, and Willis-Knighton Health System in Shreveport, LA. Rajesh received his Ph.D. from UT Southwestern Medical Center in 2012 and completed his residency followed by a proton physics fellowship at MD Anderson Cancer Center.

Jeremy Donaghue, MS, DABR is a medical physicist for Cleveland Clinic Fairview Hospital. His areas of interest include SBRT, programmatic planning, work flow efficiencies. Jeremy is the Board Representative and former secretary for the Penn Ohio West Virginia Chapter of AAPM. He is also a member of AAPM’s Med Phys 3.0 Smart Tools committee. In the past, he has presented on topics mainly focused on SBRT and MCO.
