David moved to the Department of Biological Sciences at Duquesne University in Pittsburg in the Fall of 1998 as an assistant professor, tenured in 2004, and continues to work on mariner transposons, specifically the biochemistry of a particular version called Himar1 that he developed while working at Illinois as a postdoc, and development of it as a tool for diverse insects and other organisms. He is now an Associate Professor there.
As a postdoc working with me from 1992-1998, David achieved the major breakthroughs in the work towards developing active versions of mariners that might serve as genetic tools. Thus we isolated and sequenced multiple clones of irritans and mellifera subfamily mariners, and developed the Himar1 element from the hornfly Haematobia irritans, which has already proven successful in bacteria, Drosophila, and human cells.
