Mike Crittenden joined the Genesee Community College faculty in 1981 and is currently a Professor of Physics.  In his tenure at GCC, he has been honored for his work with the SUNY Chancellor's Award for Excellence in Teaching in 1997 and the Chancellor's Award for Excellence in Faculty Service in 2008.

He has an associate degree in Engineering Science from Cayuga Community College, a bachelor’s degree in Physics and Astronomy from the University of Rochester and a master’s in Physics from Syracuse University.  

In addition to his work in the Physic’s department, he was president of the GCC Academic Senate for 13 years.



Marirose Ethington
Director of Science /Professor
Math/Science Faculty
585-343-0055 x6389

Marirose’s passion for teaching started early in her career and she was greatly influenced by her high school biology and math teachers.  After earning her Bachelor’s and Master’s degrees from SUNY Geneseo, she assisted in research of the microtubule arrangement in eukaryotic flagella using electron microscopy.  This work has led to a greater understanding of the evolutionary foundation of this ubiquitous organelle.  Her commitment to education and the community is evidenced by her involvements with Pavilion School District Board of Education as a member and as board president. She also serves on the board of the Genesee County Soil and Water Conservation District.

Marirose earned two Chancellor’s Award for Excellence in Teaching and Faculty Service. Having been raised in a dairy farming family, she maintains her connections and interest with the dairy industry today, in part through the Genesee County Dairy Princess program, which encourages young women to consider careers in this billion dollar business. 


Karen Huffman
Assistant Professor, Biology
Math/Science Faculty
585-343-0055 x6148

Dr. Huffman joined GCC in January 2011 and teaches Fundamentals of Cell Biology, Biotechnology, Microbiology and Human Disease and Genetics. She earned her Bachelor’s Degree in Microbiology from Indiana University and a Ph.D. in Biology from the University of Texas at Austin. Prior to Genesee, she taught at Mount Mercy Academy, Buffalo State College, Erie Community College, and conducted research at the University of Buffalo.

Her professional research has included investigating myxobacterium (Stigmatella aurentiaca) looking for cancer cell growth model. This early work on quorum sensing in bacteria involved chemical communication between individual cells.  Dr. Huffman also worked in a BIO-safety Level 3 laboratory, deciphering the iron-transport system of disease causing organisms on Vibro cholerae (causes cholera) and Erwinia (a corn pathogen).

She is currently co-advisor of GCC’s Outdoor Adventure Club and also holds a third degree Black Belt in Tae Kwon Do.



Gary Glaser
Associate Professor, Biology
Math/Science Faculty
585-343-0055 x6629

Gary began his GCC tenure in 2009 and teaches Anatomy & Physiology and Human Biology. He earned his Bachelor’s in Biomedical Sciences and his Master’s in Biology from the University at Buffalo. Prior to his professorship at GCC,  he researched EvoDevo, exploring the relationship between evolution and organism development.  His work contributed to the understanding of the genetics behind butterfly wing eyespot patterns.  Gary's group isolated the gene from Bicycylus anynana and, by using florescence microscopy, followed the eyespot pattern development.

Gary is also a self-taught web designer as well as a professional photographer.



Gregory Sharpe
Adjunct Instructor
