Cécile Gueidan is a mycologist and lichenologist who applies morphological and molecular biological methods to the origin and taxonomy of fungi that live in lichen symbioses and within rocks.

Early life and education

Gueidan began working on lichens during her Maitrise (1998) and DEA (1999) qualifications from Université Louis Pasteur and National Museum of Natural History, France. This included practical fieldwork experience with Claude Roux.

She then studied molecular methods for lichen taxonomy at Duke University, USA and applied them to pyrenocarpous and Verrucariaceae lichens. Through combining morphological and molecular characters, she was able to improve the taxonomy of these groups. She was awarded her doctorate for this research in 2007.

Career

Her research focuses on the evolution and taxonomy of lichenised fungi and other ascomycete fungi.

After gaining her doctorate, Gueidan carried out research at the Westerdijk Institute in the Netherlands on relationships between ascomycete fungi that inhabited rock and others involved in lichen symbioses. She then continued research into lichens within the family Verrucariaceae and related fungi at the Natural History Museum in London between 2010 and 2014. Since 2013 she has been a team leader at the Australian National Herbarium, part of CISRO.

Honours and Awards
