I am a PhD student in Electrical and Computer Engineering at the University of Toronto, where I work on integrated photonics. My research centres on light–matter interaction in III–V materials, nonlinear optics, and quantum optics.

Before moving to Toronto, I received my Master of Science in Physics, with a minor in Photonics, from École Polytechnique Fédérale de Lausanne (EPFL), Switzerland. At EPFL, I investigated the efficiency of InGaN/GaN quantum wells by deep-level optical spectroscopy for my master’s thesis with Prof. Nicolas Grandjean, and worked on all-optical poling of silicon-rich nitride waveguides for second-order nonlinear photonics with Prof. Camille-Sophie Brès.

Experiments on the electrohydrodynamic (EHD) flow characteristics of a dielectric liquid in a sharp needle-plate configuration under direct current (DC) and alternating current (AC) electric field are carried out. The current-voltage characteristics and the velocity field are simultaneously recorded for understanding the flow behavior and its mechanism. For the DC case, a critical voltage separating the conduction and injection regimes and the corresponding flow reverse is observed. Results indicate the polarity of voltage only influences the flow’s intensity in the injection regime. For the AC case, two types of signals with the same 50% duty cycle are considered. For the pulsed voltage (−2.0kV to 0), the flow generally keeps the plume structure and shows weaker strength than the corresponding DC case. For the AC signal (-2.0kV–+2.0kV), the velocity amplitude first decreases and then tends to be constant with the increase of frequency. The weak flow motion with high frequency AC field is due to conduction.
