Maria Petridou

Maria is a conservation scientist with a passion for wildlife, science, and the wilderness, and a lifelong interest in carnivore ecology and human-wildlife interactions. She has a background in agronomical studies and graduated with an MSc in Environmental Biology at the School of Biology of the Aristotle University of Thessaloniki, Greece. Her thesis was conducted at the mountains of Pindos in Greece where she developed and tested a new method for the classification-identification of individual brown bears using footprint biometric data. Since then, Maria has worked as a freelance expert on large carnivores and worked in several conservation and monitoring projects in Greece and elsewhere (French Guiana, Peru, Albania). She returned to University in 2018 to pursue her Ph.D. in wolf ecology and human-large carnivore conflict mitigation in Greece, under a State Scholarship Foundation grant (IKY). For her Ph.D., she is conducting her work using an interdisciplinary approach that combines field-based ecological sampling (camera trapping, diet analysis) and social surveys (face-to-face interviews with livestock farmers) to better understand the causes of wolf-human conflicts.
