About Marco Mariotti
I consider myself a computational biologist, and my field of study is evolution. I develop and employ comparative genomics tools to catch traces of natural selection, and interpret them to characterize biological systems. My research is typically based on large scale “omics” data, including nucleotide and protein sequences derived from genome assemblies, as well as quantitative techniques such as RNAseq and proteomics. I specifically worked on the fields of selenium biology, tracing selenocysteine utilization throughout the tree of life, and the related field of recoding (programmed exceptions to the genetic code).
