Dr. Howard Koh is stepping down as assistant secretary for health at HHS after five years in the post. Koh's primary focus was disease prevention, including oversight of the Office of the Surgeon General.
Koh is returning to the faculty of the Harvard School of Public Health, where he taught before joining the Obama administration. He will depart at the end of July, according to HHS. Dr. Wanda Jones, who serves as principle deputy assistant secretary for health, will take over his duties until a replacement is named.
