About William D. Kappele

Bill Kappele is a chemist with extensive experience in Design of Experiments (DOE), both as a researcher and teacher. He first encountered DOE at the beginning of his career at Hewlett‐Packard, where he was responsible for the design and development of dye‐based thermal inkjet inks. He earned numerous U.S. patents for his work. Later, at Hach, Bill developed simplified chemical analyses for water and wastewater treatment.

From Hach, Bill went on to Lexmark International, where he invented the first lightfast black ink for their inkjet printers. He then joined DOE pioneer Dave Doehlert at The Experiment Strategies Foundation, where Bill began to teach DOE to scientists and engineers.

A lifelong learner and born teacher, Bill has seen the powerful advantage that DOE training has given each of his students, from chemists and engineers who convert theories into real‐life products, to researchers who no longer rely on luck to produce results on time and within budget.

Bill draws on his depth of experience for real‐life examples to bring context to complex concepts
