Dr. Alexis Guerin-Laguette earned a PhD in Lactarius sect. Deliciosi cultivation/ecology from the Institut National de la Recherche Agronomique (INRA) and Université de Montpellier II France. He has since worked in Japan, Canada, and China and has led a program of research on the cultivation of edible mycorrhizal fungi (EMF) at the New Zealand Institute for Plant & Food Research Ltd over the last 17 years. In November 2020, Alexis established Mycotree to continue his work on EMF as a freelancer. He is a regular visiting scientist at the Kunming Institute of Botany/Chinese Academy of Sciences since 2015 and, in 2017, was granted High Level Foreign talent by the Yunnan Administration of Foreign Affairs. He has published over 25 peer-reviewed research papers and book chapters. He is an expert in the cultivation and biology of edible mycorrhizal fungi, i. e. forest mushrooms and truffles. He serves as the Technical representative of the New Zealand Truffle Association since 2016, and since 2011, he serves as the Secretary of the Scientific Committee of the International Workshop on Edible Mycorrhizal Mushrooms.
