My Ph.D. studies involve 1- the development of the first real-time intelligent system, the Intelligent Continuous Expertise Monitoring System and its predictive validity, and 2- comparing this intelligent system to in-person human instruction in simulation training.
As a medical trainee and an aspiring surgeon, I believe that the future intelligent computer systems will make ‘the most efficient teacher’ in medical training. Being at the heart of the development is exciting!

lucy.luo@mail.mcgill.caAs surgical education is shifting towards competency-based approach, simulation and artificial intelligence technologies have emerged as valuable teaching tools to help learners master operative skills in a safe environment. As an orthopaedic surgery resident, I am interested in validating novel simulation technologies in orthopaedic trauma surgery. I believe that further exploration of these new innovative educational tools will contribute to improving patient safety and learning efficiency for the next generation of surgeons.

Special interest in studying Neurosurgical expertise and measuring surgical skills objectively. Developed benchmarks for a set of novel metrics based on a group of board certified neurosurgeons performance during simulated brain tumor resections using the NeuroTouch. This research can be used to shift the neurosurgery training program from a competency-based model into a a proficiency-based model for the purpose of faster neurosurgical skills aquisition and maintenance.

I graduated with a Bachelor of Medical Sciences from the University of Western Ontario, where I specialized in Physiology. Towards the end of this degree, I developed an interest in data science/AI and its applications in healthcare, which, in combination with my passion for entrepreneurship, led me to pursue the Masters of Science in Experimental Surgery program with a specialization in Surgical Innovation at McGill.
