Martin Morgan, PhD

Martin Morgan, PhD
Director, R/Bioconductor
Dept. of Biostatistics & Bioinformatics
Phone: 716-845-6503
e-mail:  Martin.Morgan@RoswellPark.org

Dr. Morgan earned his undergraduate and Master's degrees in Botany at the University of Toronto. Dr. Morgan's PhD studies at the University of Chicago involved the evolutionary consequences of frequency-dependent selection, and of multilocus deleterious mutation.

Dr. Morgan spent 10 years as an Assistant and then Associate Professor at Washington State University, before joining the Fred Hutchinson Cancer Research Center in 2005. At the Hutch, Dr. Morgan worked on the Bioconductor project for the analysis and comprehension of high-throughput genomic data; he has led Bioconductor since 2008 and the Bioconductor project is now based at the Roswell Park Comprehensive Cancer Center.

With respect to IT Research Computing, Dr. Morgan provides training on the use of R, R-Studio, and Bioconductor in a parallel computing environment.

Daryl Nazareth, PhD, DABR

Daryl Nazareth, PhD, DABR
Medical Physicist
Department of Radiation Medicine
Assistant Professor
Medical Physics Program
University at Buffalo
Phone: 716-845-4990
Email: Daryl.Nazareth@roswellpark.org

Dr. Nazareth earned his B.Sc. in Mathematics and Physics at the University of Toronto. He earned his MS in Physics at SUNY-Binghamton, and his PhD in Physics at the University at Buffalo. He completed a postdoctoral research fellowship at the University of Maryland, and joined the faculty at Roswell Park as a Medical Physicist in 2007.

Dr. Nazareth’s research interests involve the application of novel techniques and technologies to the problem of optimization of geometric parameters for the radiation treatment of cancer. This includes the application of HPC resources to running monte carlo codes for radiation dose distribution calculations.

With respect to IT Research Computing, Dr. Nazareth’s research group provides training on the use of MATLAB, simulation-optimization, and Monte Carlo dosimetry in a parallel computing environment.
