The world’s oceans, and mathematics, have a lot to say to Eliza Michalopoulou, PhD,  associate professor in the department of mathematics at NJIT. Her work illustrates another of the many ways in which mathematics defends the nation. As a mathematician, Michalopoulou devises algorithms to help U.S. Navy engineers detect submarines in shallow water.  From her underwater (also known as acoustical) research, Michalopoulou can determine the location of submarines and whales, the earth’s changing climate, even environmental contamination. >>
