Research Interests

Bioenergy
A significant focus in my research program at the Joint BioEnergy Institute is the development of new scientific insights and novel technologies for biomass deconstruction, the process of breaking down and fractionating lignocellulos into targeted intermediates through the use of ionic liquids. This includes the development of microbes and enzymes that can tolerate and operate efficiently in the presence of these ionic liquids, and the advent of consolidated conversion operations in order to produce a scalable, sustainable, and affordable technology suitable for deployment in a biorefinery.

Biotechnology and Biomanufacturing
While the 21st century will undoubtedly be recognized for advances in the biological and life sciences, another important element in magnifying the positive impacts of these advances is to enable the US bioeconomy, especially in the realms of developing advanced biomanufacturing technologies to replace and displace current manufacturing techniques that are energy intensive and have a negative effect on the environment. My goal is to mature the science of biotechnology and synthetic biology into a BioFoundry, and to identify opportunities where biomanufacturing can have a positive impact on cost and sustainability profiles relative to conventional manufacturing approaches.

Nanotechnology and Nanostructured Materials
Another significant research interest is the development of templated nanomaterials that provide a superior performance attributes relative to bulk materials. I have worked with surfactant-based approaches for the production of tailored nanostructures with unique properties as semiconductors, photocatalysts, catalysts, and energy storage materials.

Biosciences Area FY23 LDRD Projects

December 15, 2022

The projects of 22 Biosciences Area scientists and engineers received funding through the FY23 Laboratory Directed Research and Development (LDRD) program.

A Laser-powered Upgrade to Cancer Treatment

March 23, 2022

Researchers in the Biological Systems and Engineering (BSE) Division are collaborating with colleagues at the Berkeley Lab Laser Accelerator (BELLA) Center to adapt the nascent technology of laser-driven ion accelerators to make a more effective type of radiation more readily available to patients. The mutually beneficial partnership gives BELLA scientists a real-world application around which to refine their experimental laser platform, and gives the biologists a chance to test how living tissue responds to laser-driven proton beams at FLASH dose rates.

BSE Director Blake Simmons Gives iBiology Seminar

July 15, 2020

Blake Simmons, Director of the Biological Systems and Engineering (BSE) Division and Chief Science & Technology Officer at the Joint BioEnergy Institute (JBEI), was featured in a series of online seminars hosted by iBiology.

In his first talk, he provides an overview of the advantages of using biofuels and walks through the biochemical processes required in order to convert biomass into usable fuels. He also discusses the ideal properties for advanced biofuels, the projected markets for these fuels in the coming years, and some of the key challenges associated with optimization of advanced biofuel production.
