Research interests

Microbiology, molecular biology, biochemistry, biodetection and bioremediation, bone biology and DNA repair.

I currently work on projects that use microbiology and molecular biology on mission critical short-term biodetection and bioremediation goals. I have worked extensively with in vivo and in vitro mammalian systems, studying bone biology, issues of bone growth, loss, and fracture repair, in relationship to the Wnt signaling pathway. These studies included the use of nanoparticles made of apolipoproteins and phospholipids called nanolipoproitein particles. I have also worked on understanding DNA repair mechanisms of double strand break damage, acquired from chemical and radiological insults in mammalian in vitro systems, the proper functioning of which is required to avoid gene mutations that can lead to cancer.
