Richard Castillo, PhD, DABR
Website Developer, Data Sharing & Technical Support
Principal Investigator

Richard Castillo currently holds a faculty appointment as Assistant Professor in the Department of Radiation Oncology at the Emory University Winship Cancer Institute. He completed his MS (2007) and PhD degrees (2011) in the Department of Imaging Physics at MD Anderson Cancer Center through the UT Graduate School of Biomedical Sciences, and received his initial certification by the American Board of Radiology in 2016. Dr. Castillo founded the dir-lab website as part of his PhD work to validate the use of DIR-based lung function imaging derived from CT. His current research interests include quantitative performance evaluation of deformable image registration, and quantitative function & morphometric image analysis.

Dr. Castillo was previously awarded the UT GSBS Aaron Blanchard Award in Medical Physics, an NIH Extramural Loan Repayment Award (NIH LRP), as well as an NIH Research Scientist Development Award (K-01). He is also co-investigator on an active NIH/NCI R01 (R01CA200817) evaluating safety and clinical efficacy of functional avoidance radiotherapy based on CT ventilation imaging.

Rudy Guerra, PhD

Dr. Guerra is generally interested in biological problems with an emphasis in biomedical research. Current interests include meta-analysis for genetic linkage studies, case-control studies using haplotype blocks, and identification of multiple genetic markers influencing a single trait. More recently, he has been learning about bioinformatics via macroarray studies and biological pathways. Projects in these areas are motivated by various system biology efforts with University of Texas Medical Branch (UTMB, Galveston), Baylor College of Medicine, and M. D. Anderson Cancer Center.

Thomas Guerrero, MD, PhD

Dr. Guerrero completed his M.D. and Ph.D. (biomedical physics) from the David Geffen UCLA School of Medicine in 1997 and residency training in radiation oncology at Stanford University in 2002. He received his initial certification by the American Board of Radiology in 2003. Since 2014 he has been vice chair for translational research & clinical faculty and professor at Oakland University William Beaumont School of Medicine. He holds a courtesy appointment in diagnostic radiology. His research efforts are focused on deformable image registration and its applications, as well as mathematical modeling of pathophysiological processes and the development of imaging derived biomarkers. He was awarded the NIH Director’s New Innovator Award in 2010.
