Balaji Sridhar has always liked science, but it was his father鈥檚 bad knees that were the impetus for him to study both chemical engineering and medicine. His father once was a good squash player, but had to give up playing when the cartilage in his knees wore out. With the dual graduate degrees, Sridhar hopes to someday be able to help people like his father who struggle with debilitating joint pain and reduced mobility due to damaged cartilage.
