Overview

A member of the Dartmouth faculty since 1987, Professor Lynd is an expert on utilization of plant biomass for production of energy. Spanning science, technology, and policy domains, and including leading research on fundamental and biotechnological aspects of microbial cellulose utilization, his body of work includes over 250 publications, over 35,000 citations, an h-index of 79, and an !10-index of 222 (Google Scholar), as well as 8 granted patents. Lynd is co-founder, Chief Scientific Officer, and Director of biofuel start-up Enchi Corp., Consolidated Bioprocessing Team Lead for the Center for Bioenergy Innovation, and founder and Executive Committee Chair of the Global Sustainable Bioenergy Initiative. In the past, he was co-founder, CSO, and Director of Mascoma Corp., co-leader (with Nathanael Greene of the Natural Resources Defense Council) of The Role of Biomass in America's Energy Future project, and biofuel industry representative on a committee advisory to the executive office of President Clinton on reducing greenhouse gas emission from personal vehicles. He has three times testified before the US Senate, and has been featured in prominent fora such as Wired, Forbes, Nova, and the Nobel Conference. He is a Fellow of the American Association for the Advancement of Science and has received numerous awards and honors, including: Inaugural winner of the Lemelson MIT Sustainability Prize for inventions and innovations that enhance economic opportunity and community well-being while protecting and restoring the natural environment, and the Charles D.

Research Projects

  • Lynd Research Lab

    Lynd Research Lab

    The research lab at Dartmouth led by Professor Lee Lynd is active in research on the following topics:

    • Microbial Cellulose Utilization, including fundamental and applied aspects
    • Metabolic Engineering, focusing on thermophilic cellulolytic bacteria for fuel production
    • Innovative Biomass Processing Technologies, including development, design, and evaluation
    • Sustainable Bioenergy Futures, including resource, environment, and economic development

    We approach these topics from a diversity of academic disciplines with molecular biology, microbiology, chemical/biochemical engineering providing the foundation for the first three. Consistent with the "Pasteur's Quadrant" model articulated by Donald Stokes (Brookings Institution Press, Washington, DC, 1997), we see advancing applied capability and increased fundamental understanding as having strong potential to be convergent and mutually-reinforcing, and we aspire to work in this mode.

    A central theme of the Lynd group is processing cellulosic biomass in a single step without added enzymes. Such "consolidated bioprocessing" (CBP) is a potential breakthrough, and "is widely considered to be the ultimate low-cost configuration for cellulose hydrolysis and fermentation" (joint DOE/USDA Roadmap, 2007). We are focused on production of ethanol, a promising renewable fuel. The CBP strategy is however potentially applicable to a very broad range of fuels and chemicals.
