"I built a rural community health partnership in India called Swasthya to train young women to be health care educators and leaders. Through these experiences, I learned how to conceive and execute community-wide health projects that respected cultural and geographic differences," Dr Murthy told members of the powerful Senate Committee on Health, Education, Labour and Pensions.
"As a public health educator, I created HIV/AIDS education programmes for tens of thousands of youth through an organisation I co-founded call VISIONS," said Dr Murthy, who if confirmed by the senate would be the first Indian-American to occupy the post of the top American doctor responsible for the country's health care.
Describing himself as son of an immigrant parent, Murthy, 36, said his grandfather was a poor farmer, who fought for freedom in India.
Senator Tom Harkin, Chairman of the Senate Health Committee said should that Murthy be confirmed, his calm demeanour, his excellent ability to communicate with Americans from all backgrounds, and his medical and public health expertise will be invaluable assets during the times that Americans are most concerned about their health and safety.
