Leadership Team

Peter O’Blenis

In his spare time, Peter is an active volunteer in the community and chairs Race the Runway, an annual event that raises money for local charities.

Ian Stefanison

Chief Technology Officer

Ian is a co-founder of Evidence Partners and the development lead behind DistillerSR. Ian helped create SRS, the world’s first commercially available systematic review software, back in 2001 and he’s been at it ever since. Developing the world’s leading systematic review software is a great excuse to create awesome database queries and to meet a lot of brilliant researchers along the way. As much as he is passionate about keeping the system clean, elegant and agile, he is equally dedicated to working with the research community to improve the review process for everyone.

Ian is an avid outdoorsman who keeps the Evidence Partners kitchen stocked with his homemade maple syrup – it’s amazing in coffee. He also enjoys snowboarding and de-stresses by participating in mixed martial arts.

Jonathan Barker

Chairman of the Board

Driven by a desire to improve health care research, Jonathan co-founded TrialStat – a company that delivered easy-to-use, cost effective data management software to clinical researchers and systematic review groups around the globe. In 2008, he co-founded Evidence Partners, with Peter and Ian, to focus exclusively on software to make systematic literature reviews easier and faster.

Before Evidence Partners, Jonathan served as a litigation lawyer, applying information technology to multi-million record lawsuits. He also worked at Price Waterhouse specializing in the application of information technology in healthcare and clinical research.

Genetics research, photography, and cycling are keen interests of Jonathan’s in his off hours.
