(1994) He is a Professor of Chemistry and is currently the Department Chair. He earned his B.S., from the University of Missouri, St. Louis and his Ph.D., from Texas Tech University. Dr. Johnston is a trained inorganic/analytical chemist. His research interests are in organometallic chemistry with an emphasis on the development of catalytic systems.

Education

  • Received Bachelor of Science Degree in Chemistry from the University of Missouri in St. Louis (1980) 
  • Received Ph.d. in Chemistry from Texas Tech University (1984) 
  • Additional studies at University of Tennessee Knoxville

Community Service

I have been a very active member of Highland Park Baptist church for the past 11 years. My service at the church has recently included singing on the praise team and teaching an adult Sunday School class. In the past, I have held roles as discipleship trainer, deacon, chairman of the deacons, and I sang in a quartet.

johnston-chemistry-2.jpgI have been involved with the Boy Scouts for the past 12 years. Currently, I am a committee member of troop 100. This is a very active role helping young gentlemen earn different merit badges and honors. The troop keeps me busy with various activities and overnight camp outs.

Research Goals

To make a positive impact upon Organometallic Chemistry and undergraduate education through:

  • the synthesis of new catalysts
  • catalytic activity studies of new compounds
  • the development of a methodology to synthesize a reaction specific catalysts
  • by involving undergraduate students in the research
  • develop and test new methods that improve student learning in my classes
