Our research focuses on viruses of the extremely thermophilic archaeon (also known as archaebacteria) Sulfolobus and other viruses in volcanic hot springs. These viruses are completely different, both in structure and sequence, from any other known viruses. We are interested in how these viruses and their hosts function at very high temperatures (80C = 176F) and high acidity (pH below 4). We use genetic, genomic, structural and biochemical tools to answer these questions. We are very interested in the origin and evolution of viruses and their contribution to complex life.
