Engineering is the science of solving complex technological problems and, in the case of molecular engineering, applying molecular-level science to the design of advanced devices, processes, and technologies. The Pritzker School of Molecular Engineering (PME) is at the forefront of emerging approaches to address fundamental societal challenges in such areas as quantum engineering, biotechnology and immunoengineering, advanced materials, energy storage, and a clean global water supply. The BS degree in Molecular Engineering offers undergraduates a cutting-edge engineering curriculum built on a strong foundation in mathematics, physics, chemistry, and biology. Courses in the major are designed to develop quantitative reasoning and problem-solving skills, to introduce engineering analysis of biological, chemical, and physical systems, and to address open-ended technological questions across a spectrum of disciplines. The aim is to introduce invention and design, along with inquiry and discovery, as fruitful and complementary intellectual activities. The program prepares undergraduates for leadership roles in a technology-driven society. Graduates will be positioned to follow traditional engineering paths in research, technology development, and manufacturing, or to pursue further postgraduate study in such fields as engineering, science, medicine, business, or law. Other graduates may successfully leverage the quantitative and problem-solving skills gained in their training as engineers towards careers in technical and management consulting, finance, public policy, or entrepreneurship.
