The Center for Chemical Evolution brings together a diverse group of scientists with backgrounds from several disciplines of chemistry and chemical engineering. Our continued research efforts focus on exploring chemical evolution and the chemistry associated with the origins of life. We anticipate that discoveries made within the Center will significantly contribute to this field, as well as to the greater scientific community. Our recent peer-reviewed publications are listed below.
