About

Tanjona

I am a Malagasy ecologist and develop mathematical and statistical models to better understand patterns and processes of biodiversity loss. I obtained a MSc in applied mathematics with Arthur Randrianarivony at the University of Antananarivo. I did a PhD with Ilkka Hanksi and Otso Ovaskainen at the University of Helsinki. I completed a first postdoc with Emma Goldberg at the University of Minnesota, and a second postdoc with Anthony Ives and Monica G. Turner at the University of Wisconsin-Madison (ACES), and is doing a third postdoc with Benjamin Roche at the University of Montpellier on COVID-19 modeling. I am the Scientific Director of Madagascar Biodiversity Center since 2023, and a Honorary Fellow of the University of Wisconsin-Madison since 2019.
