"Research is to see what everybody else has seen, and to think what nobody else has thought."

(i)  Sensor Characterization and Multimodal Sensor Data Processing for Off-Road Vehicle Autonomy

The aim of this project is to determine the imaging uncertainty in commonly used sensors, namely LiDAR, stereo camera, thermal camera, and echolocation sensor, for off-road vehicle autonomy and mitigate those uncertainties through image processing in real time and multi-modal sensor fusion, to maximize situational awareness in all weather conditions.

(ii) Gallium Nitride Microelectromechanical Systems (MEMS) Devices for Sensing Applications

Wide bandgap gallium nitride semiconductors exhibit great potential in the realm of MEMS-based sensors because of their distinct spontaneous and piezoelectric polarization, as well as their chemical inertness. These attributes offer the possibility of achieving remarkably sensitive conversion of strain or deflection and enable operation in harsh environmental conditions. This project primarily concentrates on harnessing this exceptional sensitivity to create portable devices for diverse sensing purposes. These applications encompass the development of handheld systems for tasks like measuring pressure in high-temperature pressure and detecting gases.

(ii) Temperature Dependent Behavior Analysis of Doped Gallium Oxide Devices and their Sensing Applications

In the dynamic realm of power electronic devices, there is a heightened requirement for enhanced withstand voltage, cost-effectiveness, and superior reliability, necessitating advanced capabilities from semiconductor materials. As a result, there's an escalating emphasis on ultrawide bandgap gallium oxide (Ga2O3) semiconductors as the forthcoming generation of semiconductor materials. For applications demanding elevated power and radio frequency (RF) functionalities, employing semi-insulating substrates becomes essential to mitigate device performance deterioration stemming from conduction losses. This study delves into the temperature-dependent characteristics of doped gallium oxide devices and evaluates potential sensing applications therein.
