Daniel Geller


Daniel Geller has been involved in biodiesel and biofuel research for over 10 years focusing on the development of novel feedstocks for Biodiesel production. He has been a technical advisor to many of the State's emerging Biofuels facilities and has guided many potential investors and entrepreneurs in their decisions regarding biofuel technologies.

Geller has been a key researcher demonstrating the use of fat as a replacement for heating oil. This practice is now widely used throughout the Southeast and has saved industry millions of dollars. Geller continues to work to help establish new biofuel facilities to produce fuels and products from biobased sources within the State. His current research focuses on new technologies utilizing wood and paper waste as feedstocks for liquid fuels. He is also working to extend the supply of poultry fat available for fuel application.
