Why Is Peter Crittenden Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Peter Crittenden is a British lichenologist. His research largely concerns the ecophysiology of lichens. Crittenden is known for using new techniques to study lichens, such as the use of 3D printing and X-ray computed tomography to study lichen structure and development. He served as the senior editor of the scientific journal The Lichenologist from the years 2000–2016; and still serves on the editorial board for the journal Fungal Ecology. Crittenden was the president of the British Lichen Society in 1998–1999, and president of the International Association for Lichenology from 2008 to 2012. He was awarded the Acharius Medal at the 10th International Mycological Congress in Bangkok in 2014, for his lifetime achievements in lichenology.
