Washington:  US President Barack Obama has congratulated two Indian-Americans who were among the three winners of Google Science Fair for their landmark research in the field of medical science and environment.

Obama met Shree Bose and Naomi Shah on Tuesday. Bose discovered a way to improve ovarian cancer treatment for patients when they have built up a resistance to certain chemotherapy drugs.

Shah in her project endeavored to prove that making changes to indoor environments that improve air quality can reduce people’s reliance on asthma medications.

The third winner Lauren Hodge studied the effect of different marinades on the level of potentially harmful carcinogens in grilled chicken.

The White House released a picture of the event on Tuesday wherein Obama is seen talking with the three winners.
