Gabriel O. Sawakuchi, Ph.D.
Sawakuchi received his undergraduate and master’s degrees in Physics from the University of Sao Paulo, Brazil. He received his Ph.D. in Physics from Oklahoma State University and completed a postdoctoral fellowship at in the Department of Radiation Physics at MD Anderson. Then, Sawakuchi joined the Physics Department at Carleton University, Ottawa, Canada as a tenure-track Assistant Professor. Dr. Sawakuchi joined the Radiation Physics Department at MD Anderson as a tenure-track Assistant Professor in February 2013. He is a member of the Physics Gastrointestinal group and a regular member of The University of Texas Graduate School of Biomedical Sciences at Houston. Sawakuchi’s research interests include radiation-induced DNA damage response mechanisms, development of new radiation detectors for applications in radiotherapy and radiobiology, and Monte Carlo radiation transport simulations.

Daniel J. O'Brien, Ph.D.
O'Brien received his undergraduate and Ph.D. degrees in Physics from University College Dublin, Ireland. The topic of his Ph.D. thesis was the dosimetry of small fields for flattened and flattening-filter-free beams and focused on the calculation of detector correction factors for small fields using measurements and Monte Carlo simulations. He completed this work with the Saint Luke's Radiation Oncology Network in Dublin, Ireland, under the supervision of Professor Brendan McClean and Luis León-Vintró, Ph.D., and continued to work there as a postdoctoral research fellow to support their research into adaptive radiotherapy techniques. O'Brien's current research at MD Anderson is on correcting for the effects of magnetic fields on the dosimetry of radiation beams from MRI-linacs.
Conor H. McFadden, M.Sc.
Senior Research Assistant
McFadden received his B.Sc. in Physics from Carleton University in Ottawa, Canada. Conor completed his M.Sc. in Physics at Carleton University under the supervision of Sawakuchi. McFadden came to work at MD Anderson in September 2013 as a research assistant under Sawakuchi. His research entails developing instrumentation for reading out fluorescent nuclear track detectors for use in radiobiological experiments. Conor also performs research on gold-nanoparticle radiosensitization.
David B. Flint, B.Sc.
In 2011, Flint began working in Sawakuchi’s lab at Carleton University, Ottawa, Canada, where he completed his undergraduate research project on the characterization of Al2O3:C OSLDs. Flint continued his work on the OSL project as a research assistant in Sawakuchi’s lab in the summer of 2012. Flint received his B.Sc. in Physics and Chemistry with a minor in Mathematics from Carleton University in the spring of 2013. He worked as a research assistant at MD Anderson from May 2013 to May 2014. He is currently a 1st year predoctoral graduate student in Medical Physics at the University of Texas Houston Graduate School of Biomedical Sciences. The current focus of his research is in the application of fluorescence nuclear track detectors (FNTDs) in live-cell imaging using confocal microscopy.
