Engineering ideas into impact

For over two decades, my research has centered on applying the engineering design process (EDP) to solve complex problems across multiple domains — from signal processing to biomedical systems, from embedded electronics to environmental sensing. I aim to bridge theory and application, creating opportunities for students and collaborators to explore how engineering can directly improve human lives, health, and learning.

Signal Processing & Wireless Communications

My early work focuses on signal recovery, channel estimation, and massive MIMO systems — with direct applications in 5G, device-to-device communication, and energy-efficient wireless networks. This foundational knowledge continues to inform many of the embedded systems we build for real-time data acquisition.

Biomedical Engineering & Wearable Health Tech

I have collaborated with partners like Samsung Vietnam and Bonbouton to develop embedded sensing systems for health monitoring. Key projects include:

  • PPG signal analysis and heart rate detection on Android

  • Fetal ECG extraction using signal separation algorithms

  • Electromyography using graphene sensors embedded in smart shoes

These systems aim to deliver affordable, practical tools for health diagnostics and preventive care.

IoT for Environmental Monitoring

In recent years, I’ve led the development of air quality monitoring systems tailored for schools. These IoT-based platforms gather and visualize data on PM2.5, CO₂, and other environmental indicators — combining STEM education, citizen science, and community action.

Our goal is to empower students and educators to engage with real-world data, connect science to lived experience, and take informed action in their own environments.

Engineering Education & Design Thinking

I’m passionate about cultivating the EDP mindset — helping students not only gain technical skills, but also develop creativity, collaboration, and resilience. I integrate design thinking into my teaching and mentor student-led projects that focus on impact-driven innovation.

From sensor design to system prototyping, I encourage learners to build, test, iterate, and share — because that’s how meaningful learning happens.

Collaborations & Funding

I’ve been fortunate to collaborate with institutions and research teams in the U.S., Germany, Japan, and Vietnam. My research has been supported by:

  • Vietnam Education Foundation (VEF)

  • Samsung Vietnam

  • Bonbouton (USA/Vietnam)

  • Vingroup Innovation Foundation (VinIF)

  • Czech Embassy, US Embassy STEM Grants

These partnerships reflect a shared commitment to advancing engineering solutions with practical relevance and global cooperation.
