Priscilla Barragan

Priscilla Carrillo Barragán  

Global Section Editor - The Americas

Priscilla pursued a PhD programme in Environmental Science at Newcastle University, where her research focused on biofuel production as a sustainable alternative to fossil fuels. Priscilla’s expertise spans applied and environmental microbiology, molecular biology, global pollution, and waste valorisation. She aims to use this knowledge to address complex environmental issues and drive positive change for a healthier planet. Priscilla has also advised the British Parliament on microplastics pollution policy as a stakeholder of the All-Party Parliamentary Group on Microplastics 2021. An integral part of Priscilla’s career is science communication, and she is excited to exchange microbiology knowledge with as broad and diverse participants as possible.
