She is a Visiting Fellow at the Centre for Environmental Policy, Imperial College London (CEP/ICL) and an Invited Assistant Professor at the department of Mechanical Engineering, Instituto Superior Técnico, Universidade de Lisboa (DEM/IST/UL). She is a Lead Author of the IPCC Sixth Assessment Report (AR6) and the UNEP Emission Gap Report. Previously, Joana was a Senior Scientist at the IPCC Working Group III on Mitigation of Climate Change and joined the scientific team of the IPCC Special Reports on Global Warming of 1.5°C and Climate and Land Use.

Her research interests focus on energy system innovations towards mitigation of global and local environmental impacts. She has a vast experience in developing environmental modelling tools to better understand the economic and environmental co-benefits of low carbon energy portfolios and to deliver policy recommendations.

She has collaborated in several international projects with industries, policymakers and international organizations in Asia-Pacific and Latin America and Caribbean regions. She has developed work on energy and climate policy for the United Nations Institute of Advanced Studies (UNU-IAS, Japan), the Asian Development Bank (ADB, Japan), the Global Environmental Facility (GEF), the EC Horizon 2020, UK Natural Environment Research Council (NERC) and UK Department of Energy and Climate Change (DECC).

Joana holds a M.Sc. degree in Environmental Engineering with specialization in bioenergy (University of Lisbon) (2006), and a Ph.D. in Urban Engineering (The University of Tokyo) (2011), with emphasis on life cycle assessment modelling of alternative fuels.
