About Kristopher Attwood


Dr. Attwood earned his PhD and MA in Biostatistics from the SUNY University at Buffalo (UB). He also earned a BS degree in Applied Mathematics from the University at Rhode Island, as well as a MS degree in Industrial & Systems Engineering from UB.

Dr. Attwood joined the Department of Biostatistics and Bioinformatics at Roswell Park Comprehensive Cancer Center (Roswell Park) as a Senior Biostatistician in 2011. He was later presented with an Assistant Professor of Biostatistics in 2012 at Roswell Park. In this capacity he has designed, reviewed and analyzed clinical, pre-clinical and translational studies for a variety of disease settings and outcomes. He is a current member of the Scientific Review and Early Phase Clinical Trial Committees. In addition, Dr. Attwood has been teaching undergraduate and graduate level applied statistics courses at Daemen College since 2008 and UB since 2019.
