Tracy L. Callender

Assistant Professor of Biology

B.A., Hunter College, CUNYPh.D., Stony Brook University


After migrating to the United States from my birthplace Barbados, I earned my B.A., in Biological Sciences from Hunter College of the City University of New York in 2003. I subsequently went on to complete a Ph.D in Molecular and Cellular Biology awarded from Stony Brook University. My graduate research built on my interests in reproductive biology and focused on the genes involved in promoting the segregation of chromosomes during meiosis, using budding yeast Saccharomyces cerevisiae, as a model organism.  Over the past few years, I have also become interested in science education, curriculum development and mentoring at the undergraduate level.

I joined the faculty of the Biology Department at LIU Post in 2015, where I teach and coordinate Introductory Biology courses for non-science majors.
