I am a former high school biology, chemistry and physics teacher. I obtained my PhD from Texas Tech University where I studied the molecular evolution of crocodiles. Since then, I've started studying the genomes of many other organisms including flies, bats, rodents and primates. However, the laboratory still maintains a crocodilian focus. We mainly study the transposable elements in the genomes we're examining. Transposable elements are segments of the DNA in a genome that can make copies of themselves. As a result, they often make up half or more of the genome's actual DNA.
