Meet Our Leadership Team

Sachin Aggarwal, CEO

As the Chief Executive Officer of Think Research, Sachin Aggarwal understands that health care systems around the world are on the brink of profound, necessary change. Scientific knowledge, clinical best practices and medical data are increasing at an exponential rate, contributing to a global knowledge crisis – with implications for clinicians, patients, governments and countries at large.

In the midst of this growing problem, Sachin sees data as the solution – and the key to system transformation. This principle drives the mission of Think Research: to organize the world’s health knowledge so that everyone gets the best care.

As part of this vision, Sachin led Think Research in 2010 through a strategic transition to become a cloud-based service provider. The move has positioned Think Research as a leader in the global health data economy, allowing the company to standardize care at scale, aggregate knowledge across health systems and improve the quality of care for patients.

When he’s not advocating for disruptive change in health care, Sachin is actively engaged in his community. A recipient of Canada’s Top 40 Under 40 Award in 2017, Sachin also sits on the Board of the Council of Canadian Innovators. He previously served as the Deputy Chief of Staff for the Office of the Leader of the Opposition prior to joining Think Research. He’s currently a Senior Fellow in Public Policy at the Munk School of Global Affairs and Public Policy, and has served as an advisor to numerous start-up and scale-up companies in the innovation sector. He was called to the Bar in Ontario and New York, and holds an MBA from the Rotman School of Management.
