Dituri got a lot done while underwater. He had 124 online interactions with students to promote stem careers.

He also taught his biomedical engineering course at the University of South Florida.

As a result of being underwater, Dituri shrank half and inch, his cholesterol fell 72 points and his inflammatory markers decreased by 30%.

Dituri will share his results at the World Extreme Medical conference in November.
