Ben Blair was raised in Sparta, Illinois, where he grew up helping on his family’s corn, soy, wheat, and farrow-to-finish farm. He always enjoyed the numbers behind how things worked, which led him to study engineering at Southern Illinois University Carbondale.

Following a short time in clinical practice, he returned to Illinois to complete a PhD with Dr. Jim Lowe. His work focused on the cull sow marketing network and strengthened his interest in advanced analytics, machine learning, and applying AI to livestock systems. He then spent two years at the University of Minnesota as a researcher while also running a consulting business centered on data and AI projects in agriculture.
