Research Summary:

Dr. Haider's major research activities focus on abdominal and pelvic magnetic resonance imaging (MRI), with a special interest in therapeutic response assessment and functional imaging of cancer using MRI and computed tomography. He has a particular interest in prostate cancer imaging, as well as in pancreatic, renal and liver cancers.

Dr. Haider has held peer-reviewed grants from Prostate Cancer Canada, the Canadian Cancer Society Research Institute, Cancer Care Ontario and the Ontario Institute for Cancer Research (OICR) for MRI-related prostate cancer research. He holds a protected research time grant from the the OICR and U of T.

He is also an active participant in functional tumour imaging research projects in radiation oncology and therapeutic response assessment trials in medical, radiation and surgical oncology for renal cell carcinoma, and metastatic disease to liver and prostate cancer.
