The Master of Science in Chemistry at the University of California, Irvine, School of Physical Sciences is a flexible, research-intensive graduate program. Students may pursue either a thesis-based or coursework-only option: the thesis-based track focuses on original research culminating in a master's thesis, while the coursework track emphasizes a broad curriculum and a comprehensive oral examination. Core research areas include analytical, organic, inorganic, physical, and atmospheric chemistry, as well as biogeochemistry and climate science. The program prepares graduates for further research, professional careers in science and industry, or doctoral studies.
