He is also vice president of the Soil and Fertilizer Alliance of China and is a committee member of the China Toxicology Association. He is proud to be the only foreign member welcomed to China’s Feed Industry Golf Group, which represents more feed tonnage than all of Brazil.

Dr. Lyons has published papers and patents in areas ranging from enzyme production to global economics and is interested in the assurance of food safety and quality throughout the entire food chain. Recently, he was named as one of "The top 50 Irish business men and women in the BRIC countries" and “40 Under 40” leaders in agriculture by Vance Publishing Corporation.

He received his bachelor’s degree in political science and environmental science in 1999 from the University of Chicago. He received his master’s degree in brewing and distilling in 2001, followed by a Ph.D. in the area of solid state fermentation, at Heriot-Watt University in Edinburgh.
