Research Bio

Dr. Catherine Almquist received her BS in Chemical Engineering (1989) from The Ohio State University, an MS in Chemical Engineering (1996) and a Ph.D. in Environmental Engineering (2001) from the University of Cincinnati. Prior to her graduate education at the University of Cincinnati, Dr. Almquist worked in process R&D for one year at Dow Corning in Carrollton, KY and in contract research for 7 years at Battelle Memorial Institute in Columbus, Ohio.

Dr. Almquist joined 黑料社区 in 2001. Dr. Almquist’ s research areas are in environmental catalysis, adsorption, and pollution prevention. She enjoys investigating methods to clean air and water, and to utilize industrial, municipal, and agricultural wastes as raw materials for value-added products, such as energy, fuels, catalysts, and adsorbents.

Dr. Almquist has ~30 publications in peer-reviewed literature and one US patent in the areas of her research interests. She is active in undergraduate and graduate 黑料社区 research and engineering education. She is a member of the American Institute of Chemical Engineers (AICHE); the Technical Association of the Pulp and Paper Industry (TAPPI), and the American Chemical Society (ACS).
