Dannisa R Chalfoun

Dannisa R Chalfoun is a Research Fellow in the Department of Engineering Science at the University of Oxford, part of Prof. Emilio Martinez-Pañeda's Mechanics of Materials Lab. She joined in 2024 as a Postdoctoral Research Associate focusing on hydrogen embrittlement in pipeline steels and welds. Previously, she completed her PhD in Materials Science and Technology at Instituto Sabato (2022), followed by postdoctoral work at the Argentinean Atomic Energy Commission’s Materials Department on corrosion and hydrogen embrittlement.

Education:

• PhD in Materials Science and Technology, Instituto Sabato, 2022
• MSc and BEng degrees (details not specified)

Research Interests:

• Hydrogen embrittlement mechanisms in steels
• Hydrogen diffusivity and trapping in alloys
• Stress corrosion cracking in sour environments
• Localized corrosion of metals in industrial applications
• Electrochemical and mechanical testing methodologies
