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 revealing their rheological behavior through visualizations, so they can be tuned and refined for creative and interaction design in makerspace.
Committee:
Cesar Torres (advisor),
Ming Li,
Debashri Roy,
Emma Yang
Keywords: Fluid Sensing, 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/AFE/embedded firmware, and collecting physiological datasets for blood pressure and HRV analysis.
Feb 2020 – Aug 2022
Developed embedded biomedical signal acquisition—developing nRF52832 BLE firmware, integrating ADS1299 biopotential front-ends, and applying signal processing/filtering for ECG and signal analysis.
May 2019 – Sept 2019
Implemented embedded test automation for medical imaging systems—writing Arduino firmware, building a LabVIEW producer–consumer GUI to interface with X-ray simulator hardware, and running test protocol and mechanical validation on imaging catheters.
