Dr. Ramesh Sharma can add a doctoral degree to his resume. The 85-year-old will graduate with a doctorate in mechanical engineering on Friday, December 13. “Once I completed my master’s [in 2007 at UTA], I had a choice to do a Ph.D. in mechanical engineering, but I chose to enhance my knowledge in math, in part because I was so impressed by Hristo Kojouharov and Benito Chen,” Ramesh said.
