Research

Questions that outlast a single study.

A research programme built at the junction of anesthesiology, chronic pain medicine, and clinical epidemiology — with older adults at its centre.

Project areas

Eight threads, one question.

Each project area below approaches the same underlying problem from a different angle: how pain, and the way we treat it, shapes function and quality of life as people age.

Project area

Perioperative pain in older adults

Opioid education and enhanced recovery pathways for patients undergoing knee replacement, designed around the realities of aging physiology.

Project area

Postoperative cognitive outcomes

Investigating the relationship between post-surgical pain and cognitive dysfunction in older adults following knee surgery.

Project area

Quantitative pain measurement

Building objective, quantitative tools for chronic pain that go beyond self-report — better suited to long-term monitoring.

Project area

Aging, mobility & low back pain

Longitudinal monitoring of mobility and chronic low back pain, and how the two erode — or protect — one another over time.

Project area

Neuromodulation for chronic pain

Exploring brain-computer interfaces as a treatment avenue for chronic neck pain, alongside evidence-based spinal cord stimulation criteria.

Project area

Regional anesthesia & nerve blocks

Technique, safety, and outcomes research spanning caudal blocks, pulsed radiofrequency, and peripheral nerve interventions.

Project area

Medicinal cannabis for pain

Work through the Michael G. DeGroote Centre for Medicinal Cannabis Research into cannabinoids for chronic non-cancer and cancer-related pain.

Project area

Evidence synthesis & guidelines

Systematic reviews and multisociety clinical practice guidelines — turning fragmented evidence on corticosteroid injections and chronic pain interventions into usable recommendations.
