Recent Honors, Awards and Service Activities:

May 20, 2003 – Recognition of Outstanding Service as Chairperson of the Committee on Minority Education July 1, 2000 to June 30, 2003 by the American Society for Microbiology at the 103rd General Meeting, Washington, DC.


April 30, 2008 – Recognition for 15 years of service to TSU as Chair of the Department of Biological Sciences


June 11-13, 2008 – Appointed as member of the Division of Molecular and Cellular Biosciences, Directorate for Biological Sciences, National Science Foundation, Committee of Visitors. (Purpose: The National Science Foundation has a long-standing practice of reviewing all programs on a three-year cycle. The review is performed by a Committee of Visitors (COV), which serves as a subcommittee of the Advisory Committee for the Directorate for Biological Sciences. The COV members form an independent group of external experts. NSF uses COVs to assess the review process as well as the scientific portfolio.)


November 3-4, 2008 – appointed as member of the NSF Advisory Panel for the Research Experiences for Undergraduates FY09 Panel 1


March 2009-2011 – appointed as member Ford Foundation Diversity Program Science Panel Review and served on the Ecology and Environmental Science Panel
