About A/Prof Helen Mohan

A woman with blonde hair and black glasses, smiling and touching her face with her right hand, wearing a dark top.

A/Prof Helen Mohan is a colorectal and robotic surgeon with a particular focus on colorectal and anal cancer, advanced cancer and complex surgery. She holds public appointments as a Consultant Colorectal Surgeon at the Peter MacCallum Cancer Centre and Austin Health.

Helen completed her colorectal surgical training in Ireland before moving to Melbourne with her family in 2021 to undertake fellowship training in Robotic Surgery and Advanced Cancer at the Peter MacCallum Cancer Centre, as well as a fellowship at Austin Health. She is a dual Fellow of the Irish and Australasian Colleges of Surgeons and has completed a PhD in intestinal inflammation and cancer.

Alongside her clinical practice, Helen is actively involved in research and surgical education. She is Director of Clinical Research at the International Medical Robotics Academy (IMRA) and an Associate Professor at the University of Melbourne. She also leads a graduate research programme in robotic surgical education, cancer surgery and proctology.

Helen is a Council Member of the Royal Australasian College of Surgeons (RACS), a founding member of the International Colorectal Outcomes Registry Collaborative (ICORC), and is Deputy Research and Education Lead, Lower GI Tumour Stream, VCCC Alliance.

Every patient is different, and their care should reflect that. A/Prof Helen Mohan provides personalised colorectal, robotic and general surgical care, taking into account your diagnosis, individual circumstances and treatment goals.

With a particular focus on colorectal and anal cancer, advanced cancer and complex surgery, Helen combines specialist surgical expertise with a thoughtful and patient-centred approach. She takes the time to explain your diagnosis, discuss the available options and ensure you feel informed and involved in decisions about your care.

Where surgery is required, treatment is carefully tailored to the individual, drawing on robotic and minimally invasive techniques where appropriate. From your first consultation through treatment and follow-up, the focus is on providing clear, considered and compassionate care at every stage.

Colorectal Care Tailored to Your Needs

Research and evidence-based surgical care

Research forms a significant part of Helen’s clinical and academic work, with particular interests in advanced colorectal cancer, rectal cancer, pelvic exenteration, peritoneal malignancy, robotic surgery and surgical education.

A key focus of her work is the development of surgical research infrastructure that supports access to high-quality evidence and enables research to be more effectively integrated into clinical care.

Helen is an Associate Professor at the University of Melbourne, Director of Colorectal Surgical Research at Austin Health and Director of Clinical Research at the International Medical Robotics Academy. She also serves as Deputy Research and Education Lead for the Lower GI Tumour Stream at the VCCC Alliance.

She also has an ongoing interest in supporting junior researchers and strengthening opportunities for collaborative surgical research.

Helen welcomes contact from researchers and collaborators interested in collaborative research. She can be contacted at admin@drhelenmohan.au.
