President Obama appointed Todd Park as the administration's chief technology officer on Friday, replacing Aneesh Chopra, who resigned in January.
Since August 2009, Park has served as the chief technology officer for the Department Health and Human Services (HHS).
At HHS, Park led the creation of HealthCare.gov, which promotes the president's healthcare legislation and allows consumers to compare health insurance plans by zip code. He also helped launch the Health Data Initiative, which allows the public to access troves of HHS data online.
Park received a bachelor's degree in economics from Harvard University and co-founded a health information technology company in 1997. He has also served as a senior fellow at the Center for American Progress, focusing on health IT and healthcare policy.
Correction: This story previously said Park would also temporarily serve as associate director for technology. Tom Power, the deputy chief technology officer for telecommunication, will serve that role until a permanent replacement is found.
