Dr. John Bartlett

Program Director, Diagnostic Development

Personalized medicine requires personalized diagnostics. As the impact of the deep molecular characterization of cancer and other diseases is translated into clinical management of patients a new wave of molecular diagnostic tools are emerging. Dr. John Bartlett’s research is focused on the development of novel diagnostic approaches to stratified medicine predominantly in breast and prostate cancer. By deep molecular analysis across large clinical cohorts, linked to mechanistic understanding of pathways driving therapeutic resistance, he is developing and validating novel approaches to molecular diagnostics in cancer. These novel approaches will increasingly enable a personalized or stratified treatment approach, in the clinical setting, for cancer patients across Ontario and beyond.

Opportunities to collaborate

Collaboration is the key to solving the big questions faced by researchers across the cancer spectrum. In Bartlett’s program there are opportunities to collaborate through technology access, partnership and mentorship. Bartlett’s expertise in diagnostic development and both in situ and deep molecular analysis of clinical specimens provides an ideal platform for partnership with researchers across Ontario, Canada and beyond. Bartlett is always willing to discuss scientific opportunities and solutions (over a coffee!) and to foster a collaborative approach with research and industry partners.
