Residency Administration

  • Medical Physics Residency Program Director:                                          Dr. Nathan Schneider, Ph.D. DABR

Nathan earned his graduate degree at University of Cincinnati and has been practicing Medical Physics in the Ohio River Valley area as well as the east coast for over 20 years. He was the Chief Medical Physicist of a multiple site Radiation Oncology programs in Ohio, West Virginia and Vermont and has commissioned multiple linear accelerators in that time that include Elekta, Varian, and Siemens machines. His teaching capabilities, passion for the field, and commitment to training and developing young physicists that worked under him is steadfast.  Nathan took the lead role as the director of the residency program in the Fall of 2022 and hopes to continue growing the program by training young physicists as well as performing commissioning and acceptance of a second Varian TrueBeam accelerator and Eclipse treatment planning system with 160 MLC,EPID, 3D, IMRT, VMAT, GATED, SRS/SBRT.  His unique experience, love of the field and commitment to lifelong learning and education are some of what make Dr. Nathan Schneider a valued member of our program and fearless leader.

  • Medical Physics Residency Faculty:                                                              Dr. Peter Sandwall Ph.D. DABR

Dr. Sandwall earned his doctorate from the University of Cincinnati in 2014. His area of interest was in the development of a Novel Flourometric Dosimetry System.  He has numerous publications including

Radio-Fluorogenic Gel Dosimetry with Coumarin

Real-Tme Visualization of a High Dose Rate Brachytherapy Source for the Prevention of Error

Gel Dosimetry with Radio-Fluorogenic Coumarin

Spatial Dosimetry with Violet Diode Laser-Induced Fluorescence of Water-Equivalent Radio-Fluorogenic Gels

  • Resident Faculty:                                                                                                     Dr. Stephen Lutz MD.                                                                                          
  •  Dr. Lutz is a radiation oncologist in Findlay, Ohio and is affiliated with multiple hospitals in the area, including Blanchard Valley Hospital and Dayton Veterans Affairs Medical Center. He received his medical degree from University of Michigan Medical School and has been in practice for more than 20 years.
  • Assistant Professor:                                                                                          Pat Diltz Ph.D. Chief Physicist at Mercy St. Rita’s                                            
  • Assistant Professor:                                                                                          Dr. Andrew Schneider Ph. D., DABR (R,T), CMD, CRE (R,T,M), AMP, CSD 

Dr. Schneider graduated from the Medical College of Ohio in 1985 with a Ph.D. in Radiological Sciences.  His dissertation was titled: Transcient Dose Determination at an Interface Due to Electron Beam Irradiation. He has worked for the past 35 years in Radiation Oncology Physics accepting and commissioning 16 linear accelerators including CGR, AECL, Electa, Siemens and Varian equipment: MLC and EPID acceptance, commissioning and implementation:12 RTP systems commissioned including brachytherapy and external beam systems,  5 IMRT programs established and implemented, accelerator shielding design (20 facilities), R&V systems installed and configured, brachytherapy including IVBT, UGPI, GYN, interstitial and plaque, radiopharmaceutical therapy, NRC, state and local licensing, radiation therapy QA: neutron and photon radiation surveys. IMRT, IGRT, respiratory gating,, SRS, LDR and HDR experience. Pinnacle, Eclipse, Brachyvision, Variseed, IMPAC, ARIA experience. He also has extensive experience in Diagnostic Medical Physics and Nuclear Medicine Physics.
