In 2000 Chris brought his nine years of anesthesiology and intensive care experience, along with an MSc degree in Computer Science to iSoft, a UK-based EMR vendor operating in more than 35 countries. At iSOFT, Chris served in several key leadership roles including Head of Clinical R&D, Clinical Director (Chief Medical Officer) and Product Management Director, where he oversaw a portfolio of more than 30 products driving approximately $320M of total annual revenue. Leading a team of over 200 product managers, business analysts and designers, Chris was instrumental in establishing iSOFT as a major global player in healthcare IT.

Following his years with iSOFT, Chris built a successful consulting practice focused on technology strategy, product management and major systems implementation. His clients included Lion Television Inc., Silver Lake Partners, the UK Department of Health and Skype.

His vision to add meaning to, and get knowledge from, unstructured clinical data provides the direction for Clinithink and its technology.

We believe that our vision to provide a solution that accurately structures clinical narrative in a manner that supports physician workflow, enhances processes and ultimately, improves patient care will not only give the industry an opportunity to adequately access the information they are generating but also make a positive impact on healthcare delivery as a whole.

Previously, Peter served as Corporate Vice President of the Microsoft Health Solutions Group, and was responsible for driving the company’s strategy to improve healthcare around the world through software innovation.

Under his leadership, the Health Solutions Group brought two primary software platforms to market: Amalga, a data aggregation platform for hospitals and health systems, and HealthVault, a personal health application platform designed to put individuals in control of their own health information. Both software platforms are designed to unlock the health data traditionally stored in separate information technology systems and make it readily accessible to the people who need it— whether emergency room doctors, primary care physicians, nurses, specialists, patients, or family caregivers—to make more informed care decisions.

Peter was an active member of the Institute of Medicine’s Roundtable on Value & Science-Driven Healthcare from 2009 through 2011.

Before, from 1987 to 1998, Peter served at Microsoft in various capacities, including as the director of operating systems responsible for shipping OS/2, and later for MSNBC as vice president of News and Publishing for the interactive media group.

Peter currently serves the board of directors of LabCorp Holdings of America, Freedom Innovations, LLC, Adaptive Biotechnologies Inc., higi llc, and Clinithink Ltd. and on the board of trustees for the Fred Hutchinson Cancer Research Center.

He speaks at industry conferences on innovation and the impact of technology, and has contributed to leading publications including Health Affairs, Forbes and The Washington Post. He shares his observations and opinions on health in his personal blog, Neupert on Health.
