14. Shirley Strum Kenny

As president of Stony Brook University, Kenny oversees more than 14,000 employees for the largest single-site employer on LI. Her decisions also impact SBU’s many undergraduate and graduate students. In addition, the university has a host of significant satellite operations in the arts and sciences, such as Brookhaven National Lab, which is managed for the Department of Energy by a joint venture founded by SBU and Batelle, a nonprofit science organization. The lab alone brings some $22 million into the LI economy each year; the university, more than $2 billion.
