MGM's Tom Petes received the Yeast Genetics Meeting Lifetime Achievement Award in Los Angeles in August 2022. Tom's research concerns the mechanisms of meiotic and mitotic recombination, DNA repair, the control of telomere length, and the genetic regulation of genome stability (emphasizing instability caused by mutations affecting DNA replication) in the yeast Saccharomyces cerevisiae. One recent area of research is how the frequency of mutations and chromosome rearrangements varies in different regions of the genome.
