David Worthington

I was well established in my engineering career in 1984 when, at age 39, I came down with Type 1 Diabetes (T1D). I was always technically inclined, and majored in physics in college, then did graduate work in Cybernetic Systems. My focus was on engineering control systems, including adaptive control and model-based control, as opposed to traditional feedback control.
