<h1>Biography</h1>
<p>Tengxiang Zhang is an Research Associate Professor at Institute of Computing Technology, Chinese Academy of Sciences, where he works at the Pervasive Computing Research Center. With a background in both CS and EE, Dr. Zhang’s research lies in the technical side of ubiquitous computing and human computer interaction. His work enables access to the digital world anytime anywhere by developing wearable sensors, IoT tags, and AI-agent-based interfaces. He publishes on top-venues including
<a href="https://dl.acm.org/conference/chi" target="_blank" rel="noopener">CHI</a> and
<a href="https://dl.acm.org/journal/imwut" target="_blank" rel="noopener">IMWUT</a>, and has been honored with two paper awards. He serves on the SIGCHI Sustainability Committee and the CCF HCI and Ubicomp Technical Committees. His work falls into three categories: 1) Wearable and skin sensors, 2) Ultra-low-power IoT tags and localization systems, 3) AI-agent-based interaction interfaces.</p>
<!-- focuses on Human-computer Interaction, Ubiquitous Computing, and Applied Machine Learning during his PhD at Tsinghua University, when he was advised by [Prof. Yuanchun Shi](https://pi.cs.tsinghua.edu.cn). He also has a deep understanding of electromagnetics advised by [Prof. Andrea Alu](http://www.alulab.org/) at UT Austin and [Prof. Tiejun Cui](https://scholar.google.com/citations?user=-h-1eJsAAAAJ&hl=en) at Southeast University. He has 10+ publications at top venues including SIGCHI and IMWUT. Please read the Research Interests section for a thorough overview of my research and previous work. -->

<p align="center"><img src="/img/method.png" /></p>
Digital content is breaking out of the screens into the physical world with the help of augmented reality and IoT technologies. How do we manage and interact with digital content and physical objects in a natural, consistent, and spontaneous way? I develop IoT sensing systems (e.g., millimeter wave tags) to digitalize the physical world, build stretchable skin sensors and smart wearables (e.g., glasses, rings) to monitor human states and behaviors, and design AI-agent-powered systems to describe and understand the tagged physical world, the digital metaverse, and the humans. Thus, my previous work falls into three categories:
<ol>
<li><b>IoT Tags and Localization Systems</b>. I design ultra-low-power backscatter sensing tags that is suitable for pervasive deployment. I use head-mounted radars to calculate their 3D spatial coordinates.</li>
<li><b>Wearable Sensors</b>. I prototype smart rings and smart glasses to sense both explicit (e.g. gestures) and implicit (e.g. facial expression) interaction behaviors to understand human intent from multi-modal input channels.</li>
<li><b>AI-agent-based Interaction Systems</b>. I develop novel multi-agent-based system framework that understands interaction inputs in a zero-shot manner, manages context information, and grounds the interaction behaviors to available system actions.</li>
</ol>
