Short Bio

PERSONAL INTRODUCTION

I am an environmental scientist and an expert on air quality modelling and monitoring. I have completed my doctoral degree in Science from University of Saint Joseph and Environment and Sustainability from Universidade NOVA de Lisboa. Over the past years, I have taught classes in the undergraduate and postgraduate levels at the Faculty of Health and Environmental Sciences (FHES) at the University of Saint Joseph (USJ). In addition, I have been an invited speaker to give a lecture in a workshop co-organized by Sustaincia and Hong Kong Data Lab. Furthermore, I have been an invited speaker to share my experience in sustainable career in Macao International Environmental Co-operation Forum & Exhibition (MIECF). 

Being fluent in English, Mandarin, and Cantonese, I believe it would add great values to my teaching and research. In addition, I have been giving interviews to the media in Macau about my research and the issues of air quality in Macau, which included TDM Canal Macau, TDM Radio Macau, Macau Business, Hoje Macau, Jornal Tribuna de Macau, Macau News, and Plataforma Media. I have also attended a variety of international conferences in Portugal, Germany, Malaysia, Indonesia, Hong Kong, and Macau to present my research in both oral and poster presentation. My doctoral dissertation, “Air Quality Management in Macao – Assessment, Development of an Operational Forecast, and Future Perspectives,” examines the air quality trends in Macau and develop an air quality forecast for Macau in collaboration with the Macau Meteorological and Geophysical Bureau (SMG).
