Profile

Dr. David Johnson came to the UD Chemistry Department in 1985. Dr. Johnson taught analytical chemistry, general chemistry and environmental chemistry, mentored first year students and also advised several majors. He led the renovation and furnishing of the department's state-of-the-art chemical instrumentation laboratory, named the Bro. John J. Lucier S.M. Chemical Instrumentation Center. Dr. Johnson also taught courses for the Premedical Programs. 

Dr. Johnson spent much of his research time at Wright-Patterson Air Force Base working with government scientists within the field of lubricants. Undergraduate students who chose to do their research projects with Dr. Johnson were afforded the opportunity to work with him at WPAFB. He was also successful in publishing his research findings.
