Research Interests

Research Interests
Long interspersed elements (LINEs) are an abundant and diverse group of autonomous transposable elements (TEs) that are found in eukaryotic genomes across the tree of life. LINEs also mobilize the non-autonomous short interspersed elements (SINEs). SINEs appropriate the protein machinery of LINEs to replicate. The movement of LINEs and SINEs have been implicated in progression to cancer and in genome evolution including modulate gene expression, genome rearrangements, DNA repair, and as a source of new genes. LINEs replicate by a process called target primed reverse transcription (TPRT) where the element RNA is reverse transcribed into DNA at the site of insertion using a nick in the target DNA to prime reverse transcription. LINEs encode protein(s) that are used to perform the critical steps of the insertion reaction. LINE proteins bind their own mRNA, recognize target DNA, perform first-strand target-DNA cleavage, and perform TPRT. The proteins are also hypothesized to perform second-strand target-DNA cleavage and second-strand element-DNA synthesis, although the evidence for this is sparse (1–18). The early branching clades of LINEs encode a restriction-like endonuclease (RLE) while the later branching LINEs encode an apurinic-apyrimidinic DNA endonuclease (APE). Both types of elements are thought to integrate through a functionally equivalent integration process. I study the structure, function, and integration of RLE LINES.

Teaching Interests

Teaching Interests
I primarily teach the foundational undergraduate course in cell and molecular biology. I have also taught graduate courses in mobile DNA and molecular biology.

Biography

Biography

I received a my Bachelor's degree from the University of Colorado and my Doctoral degree from the University of Utah where I also spent considerable time skiing and climbing. I spent my postdoctoral years at the University of Rochester in New York. I study Long INterspersed Elements. (LINEs), also known as non-LTR retrotransposons.
