Around this time last year, I wrote a Gates Notes post that began: “I just returned from my visit to India, and I can’t wait to go back again.”

Last week, I got my wish and returned to India—and now that I’m home, I can’t wait to go back for another visit.

My goal was to get an update on some of the world-changing ideas and inventions that are coming out of India, and that’s exactly what I got. I spent four days there, meeting with political leaders, government officials, scientists, philanthropists, women who are lifting their communities out of poverty, and many others. The Gates Foundation funds more work in India than in any other country (other than the United States), and it’s always uplifting and educational to be there in person and see the impact of the efforts we’re supporting. Here are a few photos from my visit.
