Ian King is a molecular biologist and geneticist, whose research has focused on the mechanisms of complex genetic disease, including addiction and Autism Spectrum Disorder.

He trained as a Clinical Molecular Geneticist at the University of North Carolina, Chapel Hill, and worked in industry before joining University Health Network in 2018.


Research Synopsis

Research interests include application of new technologies to molecular diagnostics and the treatment of inherited disease and cancer, especially in the areas of artificial intelligence and health informatics.

With the advance of genomic sequencing technologies, the generation of massive quantities of sequence data for genetic diagnosis has become easy and inexpensive. However, interpretation of these data is laborious and difficult, and limits the scale to which genomics can be applied in the clinic.

It is widely recognized that artificial intelligence (AI) and machine learning is the most promising approach to automating the interpretation of genomic data, and the implementation of these technologies in the clinic will be a vital area of study in the near future.

The Advanced Molecualar Diagnostics Laboratory (AMDL) at Princess Margaret Hospital has contracted with IBM to use the Watson for Genomics (WfG) platform to interpret data from gene sequencing panels used to diagnose and assess risk for leukemia and solid tumors.

WfG will be used to analyze historical data from clinical testing in order to compare the performance of WfG to the manual curation and interpretation of sequence data that is currently in practice at AMDL. The concordance between WfG and other publicly and commercially available knowledge bases also will be evaluated using metrics developed in the initial evaluation. In addition to historical data, we plan to evaluate WfG and other AI platforms and knowledge bases for real-time evaluation of patient sequencing results from ongoing large-panel tumor sequencing studies active at UHN, with the aim of evaluating the impact of recommendations from these platforms on clinical practice and patient outcomes.

The overall goal of this research will be to develop benchmarks for the use of AI in the clinical laboratory that will inform other labs in Canada and internationally adopting this technology. Evaluation will focus on both clinical accuracy and on whether gains in efficiency offset the cost of using these platforms.
