Dr. Cécile Gueidan (Australian National Herbarium, CSIRO) has been a research scientist at the Australian National Herbarium in Canberra, Australia since 2014. Cécile has a diploma in Systematics from the National Museum of Natural History in Paris, France and a Ph.D. in Systematics and Evolution from Duke University in the U.S.A. Her doctoral research (2002-2007) was funded through the Assembling the Tree of Life (AFToL) project and focussed on the systematics of the lichen family Verrucariaceae and the evolution of the fungal subclass Chaetothyriomycetidae. During her Ph.D., she successfully reconstructed the first multigene phylogeny for the Verrucariaceae and, together with other experts in the taxonomy of this family, revised generic concepts within this group of lichens. Cécile also employed ancestral character reconstruction to infer the origin of lichenisation within the Ascomycetes, and more specifically the subclass Chaetothyriomycetidae. As a postdoctoral researcher (2008-2010), Cécile undertook research at the Westerdijk Fungal Biodiversity Institute in Utrecht, the Netherlands on the ecology and evolution of clinical fungi. She was involved in several large molecular phylogenetic projects focussing on the genera Fusarium and Acremonium and continued her work on the evolution of black yeast-like fungi. Following her post-doc, Cécile was employed as a research scientist by the Natural History Museum in London, UK (2010-2014), where she furthered her research into the molecular systematics of lichens, particularly focussing on the Verrucariaceae. During this time, Cécile also participated in collecting trips to various destinations, including Vietnam. These collections contributed to productive collaborations which resulted in, among others, the first comprehensive phylogenies for the tropical lichen family Pyrenulaceae. In addition, Cécile used molecular phylogenetics to infer the origins of the two main groups of rock-inhabiting fungi, in one of the few early studies that used fossil calibrations to estimate divergence times in ascomycete fungi. From London, Cécile then moved to Australia to be a researcher at the Australian National Herbarium (2014-present) where her work focusses on the molecular taxonomy of Australian lichens and the application of new Next Generation Sequencing-based approaches to unlock the genetic potential of cryptogam collections. She also leads a research project on molecular interactions within the lichen symbiosis.
