Today on Mushroom Hour we are joined by illustrious lichen expert Matthew Nelsen PhD. Matthew is a Research Scientist at the Field Museum of Natural History in Chicago. Matt's research began in botany, ecology and environmental science and has more recently gravitated towards: (i) the evolution of symbiotic associations; and (ii) the evolution of eukaryotic microbes (fungi and algae), and the roles they have played in shaping terrestrial ecosystems and nutrient-cycling over geologic timescales. Both avenues of his research attempt to link diverse fields and organismal groups. He also has conducted work addressing the timing and evolutionary consequences of ant-plant interactions. Matt thank you so much for joining us on the Mushroom Hour!
