About me

I am looking for students (PhD with full scholarship, MSc by Research) and visitors working on IoT and Robotics to join my group. Drop me an email with your CV if you are interested.

I am an Assistant Professor in the School of Informatics at the University of Edinburgh. Before that I did both my PhD study and post-doctoral research in the Department of Computer Science, University of Oxford, advised by Prof. Niki Trigoni and Prof. Andrew Markham. I also work closely with Prof. John A. Stankovic. My PhD study was generously funded by Google DeepMind. Prior to Oxford, I received my MEng degree in 2015 from Nanyang Technological University (NTU), advised by Prof. Lihua Xie.

Research

Broadly, my research interests revolve around the systems and modeling challenges when computers collect and reason about multi-modal data to interact with the physical environment. Within this broad notion, my research primarily focuses on the cyber-physical systems and autonomous systems, increasing their reliability, intelligence and security in the wild. I argue for a holistic approach by leveraging tactics from wireless systems, machine learning, mobile robotics, usable security&privacy and design novel methods at the boundaries of these areas.

More recently, my research thrusts lie in the following topics specifically around two MR systems - Mobile Robotics and Mixed Reality:

  1. Robust SLAM under visual degradation (e.g., darkness, fog, smoke or scarce visual cues).
  2. Safe Human-Robot collaboration via mixed reality (e.g. smart construction sites).
  3. Trusted localization and perception on mobile platforms (e.g., driverless cars).
  4. Physical-aware neural sensor fusion (e.g., sensor calibration without pain).
