Dr. Eugenia Elisabet Montiel

  • Former Postdoctoral Associate
Eli was a postdoctoral associate. Her PhD work focused on the evolutionary genetics of transposable elements in grasshoppers with different system of B chromosomes.

At the Valenzuela lab she worked on a phylogenomics project to study the repatterning of turtle genomes responsible for the co-evolution of diploid number and sex determination, as well as sex chromosome evolution in turtles. This work was funded by the National Science Foundation (MCB 1244355 to N. Valenzuela).
