Graduate Students



Zacharie Léger

Ph.D. Candidate

Zacharie Léger completed his undergraduate degree in physics at the University of Toronto in 2016. There he completed research on the optimization of direct light coupling from a fibre optic cable to a plasmonic metal grating for sensor applications under the supervision of Prof. Kherani, along with the use of fast pulsed gates for scalable trapped ion quantum computing, under the supervision of Prof. James.

Wanting to continue research in the advancement of quantum technologies, he joined Prof. Helmy to pursue an M.A.Sc. in photonic. He is currently working towards developing a non-degenerate entangled photon source tailored to enable communications between quantum system through fibre-based quantum networks.



Charles Lin

Ph.D Candidate

Charles obtained his B.A.Sc. degree in 2010 and M.A.Sc degree in 2012, both in Electrical Engineering at the University of Toronto. He is currently pursuing his Ph.D degree and his research interests include silicon photonics, nanoplasmonics, and 2D materials.



Emily Storey

M.A.Sc Candidate

Emily received her H.B.Sc in Physics, Astronomy and Mathematics in 2016 from the University of Toronto (Mississauga). During her undergraduate studies she did research with the Milstein Laboratory for Biological Physics; her senior thesis was a collaborative project which investigated the detection and sorting of fluorescently-labelled plasmids in a microfluidic device.

She is currently pursuing her M.A.Sc in the Helmy group with a focus on Raman spectroscopy for optical detection and characterization of contaminants.



Han Liu

Ph.D. Candidate

Liu Han received his bachelor degree in optical engineering from Tianjin university, PR China, in 2016. He is now pursuing his M.Asc degree, focusing on designing nonlinear waveguide for photon pairs generation.



Duxuan Wu

M.A.Sc Candidate

Duxuan received her B.S. degree in 2016 from School of Science, Wuhan Institute of Technology, PR China.Her major is Optical Information Science and Technology. During her undergraduate, she has done several projects about Raman spectroscopy, such as “Precise quantitative and qualitative studies of Artemisinin(drug) by Raman spectroscopy", and “Raman studies on irradiated and expired deterioration of Ebastine(drug)".

She is currently pursuing her M.A.SC degree and working on “Raman enhancements by microfluidic device based on hollow-core photonic crystal fiber (HC-PCF)” and “fiber laser design”.
