Research Summary:

Dr. Chin is a clinical medical physicist at the Odette Cancer Centre. He is the primary resource physicist for the Mosaiq record and verify system, and the head and neck site group at the centre.

He has supervised 13 clinical research projects since 2012 led by fourth-year medical physics, therapy and summer students. These projects include innovations in adaptive re-planning for pancreatic and head and neck patients, automated plan check quality assurance of treatment plans and beam segments, optimal pass criteria for IMRT quality assurance, and in vivo electronic portal imaging device dosimetry. The software and protocols from these projects have often been implemented immediately into clinic.

Beyond the clinic, he is involved in several funded research projects. As part of the Ontario Consortium for Adaptive Interventions in Radiation Oncology, he is the primary investigator for a study investigating adaptive strategies for pancreatic patients using the TomoTherapy system and daily megavoltage computed tomography imaging. He is also a co-investigator on a Canadian Breast Cancer Foundation grant with Dr. Greg Czarnota, in which he is assessing diffuse optical tomography and spectroscopy of breast cancer patients for monitoring of early chemotherapeutic response.

He is also involved in integrating biophotonics into the radiation therapy clinic. Working with Dr. Stanley Liu, Dr. Chin has investigated the role of diffuse optical spectroscopy in quantifying radiation-induced skin erythema, particularly for preclinical evaluation of novel anti-inflammatory drugs.
