Integrating AI in

oncology research and

clinical practice

Welcome to the J. Tsui Lab – Where AI Meets Oncology

At the J. Tsui Lab, we are passionate about pushing the boundaries of what AI can do in oncology. From automating treatment planning to working towards personalized radiation therapy, we’re here to make a difference in the lives of patients.

About

James Tsui

BEng, MSc, MDCM, PhD, FRCPC

Dr. James Tsui is a Radiation Oncologist at the MUHC, an Assistant Professor in Clinical Oncology at the McGill University, the Director of the Radiation Oncology Clinical Trials Unit, and FRQS Junior 1 Clinician-Scientist. He is also an Associate Member of the Graduate Program in Biological and Biomedical Engineering, the McGill Physics Unit, and Surgical and Interventional Sciences.

He completed his Bachelor’s Degree in Electrical Engineering at Concordia University in 2006 and a PhD in computational neuroscience at the Montreal Neurological Institute / McGill University in 2013. He later obtained his MD degree in 2015 and completed his residency training in Radiation Oncology in 2020 at McGill University.

To further his sub-specialization training, he completed a Brachytherapy Fellowship at the Brigham and Women’s Hospital, Harvard, Boston in 2021, and a Professional Master’s Degree in Artificial Intelligence with a focus in Deep Learning at MILA / Université de Montréal in 2023.

His research interests focus on the intersection of machine learning and medicine, with the goal of bringing artificial intelligence into his oncology research and clinical practice.

Areas of Clinical Focus

Current Select Projects

Personalizing Sarcoma Treatment

Our current sarcoma project is focused on integrating AI into the radiation therapy workflow to enhance treatment delivery. In addition,  we are also exploring how to safely administer higher doses of radiation to improve tumor control without increasing the risk of side effects.

Project supported by the Cedars Cancer Foundation

Geriatric-oncology Admission Prediction Tool

This project uses machine learning to predict hospital admissions for elderly cancer patients presenting to the emergency room. The goal is to provide a tool that would facilitate early intervention to reduce patients' length of stay in the emergency department and improve overall care efficiency.

Project supported by the MUHC Foundation

Federated Learning in Radiation Therapy

This project focuses on using a federated approach to develop a deep-learning segmentation tool for lung lesions in Stereotactic Body Radiation Therapy (SBRT). In collaboration with CISSS-CA, CHUS, and CHUM, we aim to build a model that enhances the precision of treatment while ensuring data privacy by sharing model weights across institutions rather than patient data.

Project supported by the Cedars Cancer Foundation

Multimodal AI for Bladder Cancer

This project focuses on predicting patient response to concurrent chemoradiation. By integrating various data modalities, we aim to develop an AI model that can accurately predict treatment outcomes, helping to optimize therapeutic decisions for bladder cancer patients.

Project supported by Dr. Wassim Kassouf lab and by the Montreal General Hospital Foundation

Students

Douaa El Abiad

Douaa is a PhD student in Biological and Biomedical Engineering at McGill University, co-supervised by Dr. James Tsui and Dr. Natalia Gorelik. She is currently working on deep learning methods to identify high-risk tumour subregions in soft-tissue sarcoma. Douaa holds a BSc in Physics from the Université de Montréal and an MSc in Medical Physics from McGill, where she studied skin dose in head and neck radiotherapy. She is passionate about research in cancer imaging, medical image analysis and artificial intelligence, with the goal of improving patient treatment and quality of life.

Alexi Houle

Alexi is a M.Sc. student in Biomedical Engineering at McGill University and the RI-MUHC. He completed his B.Eng. in Computer Engineering at Université de Sherbrooke, where he specialized in artificial intelligence and machine learning. His research interests include medical AI, digital pathology, and multimodal data analysis, with a focus on developing computational tools to support precision medicine and clinical decision-making. Outside of research, he enjoys reading, hiking and traveling.

 Megan McLoughlin

Megan is a Master's student in the Medical Radiation Physics program at McGill University, where she is conducting research on federated learning methods for automated lung lesion segmentation in radiation oncology. She earned her Bachelor of Engineering in Mechanical Engineering from Memorial University of Newfoundland and plans to pursue a career in clinical medical physics. Megan is interested in the intersection of medical imaging, artificial intelligence, and patient care, and enjoys exploring how new technologies can be translated into meaningful clinical impact.

 

Daniele Comitogianni

Daniele is a Data Scientist at the Research Institute of the McGill University Health Centre (RI-MUHC) and a Master's candidate in Biomedical Engineering at McGill University. He holds a BSc in Computer Science from Concordia University and previously worked as a quantitative researcher. His work spans machine learning and applied NLP, including large language models, with a focus on bringing deterministic AI systems to clinical oncology workflows, and an interest in neuro-symbolic and agentic systems. His current research develops and validates a system for clinical trial eligibility pre-screening in prostate cancer, combining LLM-based extraction from bilingual clinical documents with symbolic reasoning.

 

Cameron Jeffery

Cameron is an M.Sc. student in Medical Radiation Physics at McGill University, where he will be using federated learning techniques to develop AI-based medical image autosegmentation tools in collaboration with other Québec healthcare institutions. He earned his B.Sc. in Physics at McGill University, where he worked on research projects related to microwave-based medical imaging and dose visualization tools for head and neck radiotherapy. Outside of academics, he enjoys exercise, reading, and Formula 1.

Rachel Chevalier

Rachel is a second-year master's student in the Department of Biological and Biomedical Engineering at McGill. Her project investigates the predictive power of the antibody IgA and its potential hormonal regulation in the bladder, aiming to explain sex differences in bladder cancer and to support the development of a machine learning algorithm that informs treatment protocols. Outside the lab, she enjoys crafting, discovering new music, and traveling.
