Wayne received B.S. and M.S. degrees in Biology from the California State University, Northridge in 1974 and 1979 respectively. He joined the Jet Propulsion Laboratory in 1974 and is currently a research scientist in the Biotechnology and Planetary Protection Group. He has been actively involved with the implementation of Planetary Protection for current and previous space missions, including Mars Science Laboratory, Phoenix, Mars Reconnaissance Orbiter, Mars Exploration Rovers and Mars Pathfinder. He actively participates in research involving sterilization, cleaning, and validation of spacecraft hardware and is doing applied research on evaluating microbes embedded in solid materials. Recent research activities include investigations into dry heat microbial reduction, a task that evaluates bacterial spore inactivation at elevated temperatures. Wayne also manages an archive task that preserves and characterizes microbes isolated from spacecraft as they are assembled.
- Sterilization and microbial reduction, by dry heat, and other mechanisms
- Microbial asssment of microbes embedded in solid materials
- Implementation of mass spectrometry techinques for the identification of microbes
