I am a chemical engineer and battery researcher who works with time-resolved data. In my PhD at NTNU, I measure electrochemical, strain and pressure signals from battery cells over weeks, and work out which chemical or mechanical process sits behind each change.

My work combines electrochemistry (EIS, cyclic voltammetry, chronoamperometry, galvanostatic cycling, PITT), operando and ex-situ X-ray diffraction, SEM, and custom test platforms with fiber Bragg grating sensors and load cells. I write Python pipelines for acquisition, analysis and remote monitoring, and developed a sliding-window Pearson correlation method that separates chemical and mechanical effects within a single measurement.

Before this I studied chemical engineering in Vietnam, did a master’s in Korea (thin-film photovoltaics), completed the Erasmus Mundus SERP+ joint master (Paris-Saclay, Porto, Genoa; fuel-cell membranes), and worked as a process engineer at Terumo Vietnam.
