Cambrian Innovation

Senior Research Engineer

2010-2012; Boston, MA

  • Led the planning, design, and construction phases of EcoVolt, Cambrian’s first large-scale (and world’s largest)  bioelectrochemical wastewater treatment plant.  Once construction was completed, the pilot was shipped and installed at Clos du Bois winery.
  • Performed primary research, application authoring, and techno-economic modeling for a number of grant-funded research projects, including:
    • National Science Foundation (NSF) Phase I demonstrating denitrification,organics removal, and wastewater treatment from agricultural and industrial waste streams. Currently funded for Phase 2.
    • National Aeronautics and Space Administration (NASA) Phase 1 demonstrating a sustainable closed-loop life support system with the capabilities to scrub carbon dioxide, treat wastewater, produce hydrogen and methane gas, and generate electricity.
  • Designed and built numerous custom scale-up pilot systems and electrical controls for in-house and on-site studies.

Research & Development Engineer

Trophos focused on producing electricity from natural environments using a type of bioelectrochemical system (BES) called a microbial fuel cell (MFC). Trophos targeted MFC applications where power was difficult or expensive to provide, such as for sensing apparatuses in remote locations. One of our two foci was terrestrial MFCs, where we were able to harness the ability of naturally growing bacterial communities to produce electricity from soil. As a result of this research, we deployed a system of >40 MFCs across the Boston area which were capable of producing enough electricity to power humidity and temperature sensors along with wireless communications to upload data to a central server. Our second focus was benthic MFCs, which are capable of producing enough electricity from the seafloor sediment to power a variety of sensors. We developed small bench-scale bioreactors and also deployed a pilot system into the Boston Harbor in collaboration with the New England Aquarium. After completion, I presented our findings at the International Society of Optical Engineering (SPIE) Defense, Security + Sensing Conference in 2010, and published a corresponding article.

Recently, I authored a review article focused on increasing research of benthic MFCs in the Journal of Ocean Technology.

Field Engineer

2008-2009; Cambridge, MA

Greenfuel was focused in the renewable energy field, producing biodiesel from algae grown in greenhouse bioreactors. In its time, Greenfuel developed a number of bioreactor architectures which optimized light capture to maximize algal growth. In my time, Greenfuel had built large-scale pilot systems, and I managed algae biomass harvesting operations, performed growth studies novel bioreactor architectures, and modeled the effect of humidity and temperature on system productivity.
