Meredith Protas, PhD

Dr. Protas joined the Department of Natural Sciences and Mathematics in 2014. Her research focuses on the genetics and developmental biology of cave dwelling animals that have reduced eyes and pigmentation.

  • BA, Biology, Pomona College, Claremont, CA

 

Teaching and Research

      Teaching: Cell and Developmental Biology, Genetics and Molecular Biology, Research Methodology, Science Seminar, and Developmental Biology Lab

 

    Research: We work on a crustacean species that has both surface dwelling and cave dwelling populations with extreme differences in eye size, pigmentation, and appendage length. Our goal is to investigate the genetics and developmental biology behind these differences and to understand how and why these characteristics evolved.
