He is an accomplished engineer in the application of soil dynamics to seeding, tillage and earthmoving equipment as well as the emerging area of biomass utilization. Stephens developed new tillage tool shapes and designed new crop residue management devices for seeding machines; he now holds five US and two foreign patents on seed planting technology. Stephens retired from Deer and Company in 2007. Following his retirement, he has worked with the Department of Energy, providing engineering expertise and industry experience to their research program planning.
