Asad Akram ’13 (left) and Christopher Costantino ’12 study single emulsion drop formation in a microfluidic chip in the micro and nanofabrication laboratory, one of four new facilities in the chemical and biomolecular engineering department that provide students with in-depth research and educational experiences on cutting-edge topics. Their research, mentored by Joshua Levinson, assistant professor of chemical and biomolecular engineering, is part of a larger effort to develop low-cost, portable analytical technologies for environmental science field applications.
