Research Interests: 

With a self-described “passion for science,” Dr. Arif-Tiwari’s mission is to improve the health outcomes of patients with severe and life-threatening abdomino-pelvic conditions.  She specializes in image guided biopsies and interventions involving non-invasive, advanced MRI techniques. Her main areas of interest include rectal cancer, prostate cancer and Pancreatic Ductal Adenocarcinoma, an aggressive form of pancreatic cancer with a high fatality rate.  Dr. Arif-Tiwari’s collaborations with the University of Arizona colorectal surgical oncology team have led to advances in rectal cancer staging and best treatment determinations.  Currently, Dr. Arif leads a team of scientists and physicists, who along with industry collaborators, are developing, testing and implementing a highly accurate method for prostate biopsies. Additionally, through her most recent University of Arizona Cancer Center “Sparking Bench to Bedside Team Science Project” award, Dr. Arif-Tiwari is researching the response of Pancreatic Ductal Adenocarcinoma to immunotherapy.  As Imaging Investigator, Dr. Arif-Tiwari leads multiple clinical trials for skin cancer, liver cancer and pancreatic cancer.  Additionally, she has specific expertise in the diagnosis and management Crohn’s Disease and Ulcerative Colitis.
