Thorsten Allers is a lecturer in the School of Life Sciences at Nottingham University. His research uses genetics and biochemistry to understand how DNA replication, recombination and repair operate in archaea. The archaea have only recently been discovered, they are the third domain of life alongside bacteria and eukaryotes. Archaea live in extremely harsh environments such as boiling acid pools or salt lakes, which pose enormous challenges for growth and DNA stability. Thorsten Allers is interested in how DNA replication, recombination and repair have evolved to meet these challenges, and how they operate in an evolutionary lineage that is fundamentally distinct from bacteria and eukaryotes.
