Jorge Malaquias


André Fonseca Malaquias obtained his PhD in 2021 at the University of Porto Transport Phenomena Research Centre (CEFT). During such, he was concerned with analyzing the possibility of integrating phase change materials in fire protective clothing, developing his skills in heat and mass transfer in hygroscopic porous media. During that time, he was also involved in the DIF- Jacket project where his works served as a basis for the design of an innovative firefighting jacket (

Currently, he works as a junior researcher at CEFT investigating further aspects regarding the heat and mass transport in textiles as well as human body thermoregulation. Malaquias has published papers in top Journals that have had a significant impact on the scientific community.
