Dannisa R Chalfoun BEng MSc PhD

Postdoctoral Research Associate


Dannisa joined as a Postdoctoral Research Associate in hydrogen embrittlement in January 2024 to Prof. Emilio Martinez-PaƱeda's group: Mechanics of Material Lab at Jenkin Building, Department of Engineering Science. She obtained her PhD in Materials Science and Technology from Instituto Sabato in 2022. Since then, she has worked as an experimental postdoctoral researcher in corrosion and hydrogen embrittlement within the Materials Department at the Argentinean Atomic Energy Commission.

Her research at the Mechanics of Materials Lab focuses on understanding how hydrogen affects the fracture toughness of pipeline steels and their welds.
