Profile Picture

Steve Johnston brings an excitement to teaching about all aspects of biology.  His primary focus is in understanding the molecular biology of eukaryotic cells, especially in understanding how cells transmit information.  Dr. Johnston conducts research using the budding yeast Saccharomyces cerevisiae to answer fundamental questions about how cells work.  During the last 15 years at North Central College, all of these research projects have been carried out by undergraduate students.  The research laboratory is simply an extension of the classroom -- a place to really learn about how life works at the cellular and molecular level.  This research has been supported by grants from the National Institutes of Health and the Merck/AAAS Undergraduate Science Research Program.
