Research Description
The most exciting scientific questions are those at the crossroads of different disciplines. Genomics has revolutionized the study of biology and has reinforced the significance of Dobzhansky's famous quip, "Nothing in biology makes sense except in the light of evolution." Research in the Rokas lab combines computational and experimental approaches to investigate:
(i) the factors influencing phylogenetic accuracy and their usefulness in obtaining more robust phylogenies,
(ii) the molecular origins of multicellularity in fungi and animals, and
(iii) the origin and evolution of key genetic pathways in fungi and their association with changes in genome structure.
