Kathleen Arnos, PhD joined the Gallaudet community in 1983 as a Research Scientist in the Gallaudet Research Institute.  In 1996, she joined the faculty in the Department of Biology and is currently Chairperson of the Department of Science, Technology, & Mathematics.

Arnos obtained her PhD in Human Genetics from the Medical College of Virginia, Virginia Commonwealth University.  In 1984, she established the Genetics Program at Gallaudet which provided genetic evaluation and counseling services to deaf people through 2009 in collaboration with Virginia Commonwealth University and Children’s National Medical Center.  Over the past 30 years she has been actively involved in research on hereditary deafness to study common genes causing deafness, best practices in genetic counseling for Deaf and hard-of-hearing people, and the impact of genetic testing on the Deaf community.  

Dr. Arnos teaches courses in Human Genetics for undergraduate (BIO 411) and graduate (BIO 711) students and also teaches BIO 201 Research Methods in the Sciences.
