Dave Culley has over 20 years laboratory research experience in the genetics, molecular biology and biochemistry of organisms ranging from archeal bacteria to higher plants. His research projects currently focus on the genetics and biochemistry of filamentous fungi as related to conversion of cellulosic biomass to advanced biofuels or commodity chemicals.

He has authored or co-authored more than 50 publications, including journal articles, review articles, book chapters, conference proceedings and technical reports. Dr. Culley originally joined PNNL in 2003 as part of the Environmental Microbiology group and transferred to the Fungal Biotechnology team in the Chemical & Biological Process Development Group in 2008.
