Philip T. Pienkos
I am the Principal Manager of the Applied Sciences Group of the National Bioenergy Center at the National Renewable Energy Laboratory in Golden, Colorado. I joined NREL in September 2007 after 25 years in the biotech industry. My primary focus at NREL is on algal biofuels, and I am the center lead for this effort. In addition to my research responsibilities, I lead a group that consists of three sections — Applied Biology, Process Biology, and Compositional Analysis — and serve as line manager for sixteen technicians, scientists, and engineers who are involved in various aspects of biofuel R&D.
Research Interests
Some of the DOE-funded programmatic efforts carried out by the Applied Sciences Group are:
- Xylose yield targets
- Hydrolyzate toxicity process integration
- 2012 process demonstration
- Analytical development
- Arabinose utilization chemical transformations (CT)
- Biological transformations
- Feedstock process interface.
In addition to these activities, I am the PI or co-PI on a number of algal biofuels projects that are funded by DOE, DOD, or commercial partners. These include:
- Chevron CRADA
- Algal systems biology
- Algenol Integrated Biorefinery
- Sustainable Algal Biofuels Consortium.
I have been very active in the international algal biofuels community, resulting in my being named #60 in Biofuels Digest's list of the top 100 people in biofuels in 2010. I played a role in writing an algal biofuels report to Congress (released in 2008) and in organizing the DOE algal roadmapping workshop in December 2008 as well as helping to draft the roadmap itself, which was published in 2010. I was a co-author on the International Energy Agency Task 39 report on Current Status and Potential for Algal Biofuels Production. I was selected to serve on the steering committee of the fledgling Algal Biomass Organization in 2007 and was elected to the board of directors in 2008 on which I served until 2011. I remain involved with ABO by serving on the Technical Standards Committee and by chairing the Events Committee.
Much of my time is spent in partnership development at NREL, and I am involved in discussions with both public and private organizations to identify collaborative opportunities in various aspects of biofuel R&D involving both cellulosic and algal biomass.
My technical experience spans a wide range of topics including:
- Molecular biology
- Microbial physiology
- Fermentation development
- Metabolic engineering
- Enzyme and protein engineering
- Technoeconomic analysis.
