ABOUT
Hi! I’m Charlie (he/him/they), born in HCMC, Vietnam; based in Dallas-Fort Worth, TX.
Currently a PhD student in Human-Computer Interaction (HCI) at University of Texas at Arlington,
where I work with
Dr. Cesar Torres in
The Hybrid Atelier.
My research: building sensing systems and interactive tools that work with materials, especially fluids by understanding their rheological behavior through visualizations, supporting materials literacy for creative and interaction design.
Committee: Cesar Torres (advisor), Ming Li, Debashri Roy, Emma Yang
Keywords: Human-Material Interaction, Wearable & Sensing, and Bio-medical application.
Alongside with HCI, I also collaborate in bio-sensing and medical devices.
Last summer 2025, I was visiting researcher working with Dr. Hung Cao at Hero Lab in University of California, Irvine,
for the wearable Speckle Plethysmography (SPG) project for blood pressure sensing.

EXPERIENCE
June 2025 – Sept 2025
Built and validated wearable biosensing systems (SPG/ECG), integrating optics, embedded firmware, and collecting physiological datasets for blood pressure and HRV analysis.
Feb 2020 – Aug 2022
Designed embedded biomedical signal acquisition, developed nRF BLE firmware, integrated ADS1299 biopotential measurement, and processed ECG and EEG for analysis.
May 2019 – Sept 2019
Implemented embedded test automation for medical imaging systems, built a LabVIEW GUI to interface with X-ray simulator hardware, and validated protocol and mechanical validation on imaging catheters.
