Senior Engineer

 'Some old-fashioned things like fresh air and sunshine are hard to beat,’ Laura Ingalls Wilder once wrote. I couldn’t agree more, which is why I’ve dedicated my career to reducing air pollution.

Allison DenBleyker, an emissions modeling expert, is a senior engineer at ERG with over 15 years of experience supporting federal, state, and local agencies in their missions to improve air quality. For the U.S. Environmental Protection Agency, she has supported development of new vehicle emission standards by preparing robust emission inventories based on real-world data, including continuous traffic monitors, vehicle registration databases, and telematics datasets that identify vehicle location, timing, and speed. Also for EPA, she supports the enforcement of existing emissions standards by quantifying the excess emissions associated with non-compliance, such as disablement of vehicle emission controls. For state and local air quality agencies, Allison develops custom emissions estimation software tools on different platforms, leads projects to apply these tools and prepares presentations to explain this work to her clients' stakeholders. Through all this work, Allison has gained a depth of technical knowledge and a singular drive to make her clients’ jobs easier.  

Allison holds a B.S. in civil engineering from Texas A&M University and an M.S. in environmental and water resources engineering from the University of Texas at Austin. In her free time, she enjoys swimming, square foot gardening, and spending time with family.
