NJIT math professor helps navy detect subs; Explains global warming
The world's oceans, and mathematics, have a lot to say to Eliza Michalopoulou, PhD, associate professor in the department of mathematics at New Jersey Institute of Technology (NJIT). Her work illustrates another of the many ways in which mathematics defends the nation. As a mathematician, Michalopoulo...PNAS highlights for the week of April 4 - 8
