The Obama administration has announced that Todd Park will become the second person to hold the title of the government's chief technology officer (CTO).
The White House said that Park will be taking over direction of policy on government IT infrastructure platforms on an interim basis. He will work within the White House Office of Science and Technology Policy (OSTP).
Park had previously worked with the Department of Health and Human Services and prior to joining the federal government had worked in the healthcare IT business.
Park will be taking the role on an interim basis until a long-term replacement can be found.
"For nearly three years, Todd has served as CTO of the US Department of Health and Human Services, where he was a hugely energetic force for positive change," said OSTP director, John P Holdren.
"He led the successful execution of an array of breakthrough initiatives, including the creation of HealthCare.gov, the first website to provide consumers with a comprehensive inventory of public and private health insurance plans available across the nation by zip code in a single, easy-to-use tool."
Park takes over for Aneesh Chopra, the first man to ever hold the US CTO position. Chopra resigned earlier this year.
First established in 2009, the US CTO position was intended to improve the use of IT in the federal government. The postholder's remit covers issues ranging from public policy and communications to homeland security projects.
