— 01 · The Story

From a first
paper to
a classroom.

2017 – present

’17

Early signal-processing work in Vietnam — QRS in ECG at IEEE ICIEA, then EEG with neural networks at NAFOSTED NICS. The start of a fascination with biomedical signals.

’19

Crossing the Pacific to Texas Tech. A new chapter at the HPC center — HiperViz for live CPU-temperature visualization, plus first VR explorations of multidimensional data.

’21

A burst of visualization work: TimeRadar, JobNet, VixLSTM, HMaViz. Each one a different way to give shape to data.

’23

Third place at the IEEE SciVis 2023 contest for PlastiVis, visualizing synaptic networks — a fitting close to the Texas Tech years before the road home.

Now

Back home at VNU-HCM — teaching the next generation, leading an MRI brain-imaging grant, and building Physoom to run the faculty.
