In the world of multicellularity, the brown algae represents one of the last lineages to shift from unicellularity to multicellularity in the Eukaryotic Tree of Life. They are also are one of the largest and most important groups of primary producers in marine environments. Yet, how and when brown algae evolved remains an elusive question.
Research in the Phillips lab is focused on addressing when and how the group shifted to multicellularity. We currently have collaborations with colleagues at Rutgers University and University of Florida to use next generation sequencing of the genome of various lineages of brown algae and closely aligned heterokont outgroups.
