Group Information
HIV Vaccine Design and Development: Viruses are the most abundant entities in this biosphere. While largely known for their disruptive potential and the heavy toll they can take on human health, viruses can also be used as instruments to improve health. A research focus in the Thomas lab centers on providing a better understanding of virus-host cell interactions that influence the immune responses generated against replicating adenovirus vectors and inserted HIV-transgenes. Our objective is to use this understanding to design and develop an effective HIV vaccine.
Cancer Biology and Therapeutics: Adenovirus perturbs many of the pathways active in the development of cancer. These interactions support an additional research focus of our lab that enables us to 1) gain a better understanding of key events that occurs in cancer and 2) further understand how adenovirus causes disease (pathogenesis). We are also interested in exploring ways in which we can apply the lessons learned from our HIV vaccine studies to other endeavors, such as the creation of a therapeutic cancer vaccines.
Research Opportunities: Students in the Thomas lab will have the opportunity to acquire and develop skills in advanced immunology, molecular virology, cellular biology and other areas of biomedical research. Most of the studies are translated from cells to mice to nonhuman primates and, we hope, eventually to humans.
