About Andrew

Andrew Koehler applies his technical and research experience to add value for the support he provides AJW’s clients.

He is aided by his deep technical knowledge and skill-set, particularly in renewable energy and water remediation, and his passion for bringing clean technology to market.

He is currently a Ph.D. candidate at The Colorado School of Mines where he conducts research in the conversion of biomass-derived waste to fuels and chemicals, the destruction of per- and polyfluoroalkyl substance (PFAS), and energy policy.

Andrew also performs experiments converting waste and woody biomass to clean fuels (including sustainable aviation fuel) at the National Renewable Energy Laboratory (NREL) through a joint NREL/Colorado School of Mines Energy Fellowship.

Andrew maintains ties to the water industry as a student researcher for the National Science Foundation-funded Engineering Research Center for Re-Inventing the Nation’s Urban Water Infrastructure (ReNUWIt).
