Larry Walker is a native of Detroit and a retired Cornell University professor. During his time at Cornell, he has led multidisciplinary research activities focused on pretreatment and enzymatic scarification of lignocellulosic feedstock, abiotic and biotic interactions in aerobic degradation processes, and the application of systems biology modeling to direct metabolic activities in Saccharomyces Cerevisiae and Thermotoga neapolitana to drive more carbon to biofuels and bioproducts. He was director of Cornell’s Biofuels Research Laboratory from 2009–2015.
His research activities have yielded over two hundred peer and non-peer reviewed articles. Walker has served in numerous leadership roles including membership on the National Biomass Research and Development Technical Advisory Committee (2000–2005) and leadership of the Northeast Sun Initiative, a regional bioenergy and bioproducts initiative, from 2004–2012. He serves on the Governing Board of K. J. Somaiya Institute of Engineering and Information Technology and the Academic Council of Somaiya Vidyavihar, Mumbai, India. Since 2018. Walker is a current member of the MSU College of Agriculture and Natural Resources Alumni Association.
