I am a biofuels trader. I buy and sell ethanol, ethanol denaturant, and corn oil. I have been in the ethanol industry since 1983, when I started by buying ethanol to blend with gasoline before all of the major oil companies were buying ethanol. I have been involved with ASTM for over 25 years and am a voting member of the D02.A committee, voting on specifications for gasoline, diesel fuel, and ethanol. I graduated from Northwestern University in Evanston, Illinois with a BS in Chemical Engineering.
