About Susan

Dr. Susan De Long is an Associate Professor in the Department of Civil and Environmental Engineering at CSU. She has Bachelor’s degrees in Environmental Science and Molecular and Cell Biology from the University of California, Berkeley and earned her M.S. and Ph.D. in Environmental Engineering from The University of Texas, Austin. She has over 18 years of experience collectively working in the fields of microbiology, microbial ecology, environmental engineering, and applied molecular biology.

Her on-going research strives to advance technologies for bioenergy & chemical generation from waste materials, site bioremediation, and biodegradation of emerging contaminants. Fundamentally, De Long is interested in how microbial communities, or microbiomes, can be engineered or shaped to improve their utility for these applications. Her research group applies next-generation gene sequencing, metagenomics and metatranscriptomics to elucidate the composition and function of microbial communities in environmentally relevant systems, and uses insights gained to guide process design and operation. To date, her bioenergy projects have explored multi-stage, dry anaerobic digestion technologies and ambient temperature wet digestion technologies for organic fraction municipal solid wastes, manures, and food processing wastes. Newer research areas of interest focus on production of higher value chemicals from waste feedstocks.
