Catherine Sasseville-Lahaie
Research coordinator
I have always had a great interest in understanding the human being, but also in management and coordination. Discreet but always on the lookout, I like to manage several projects at the same time, and deploy my creativity and organizational skills to facilitate the achievement of common goals. Very curious by nature, it is a great pleasure to dive into the field of quantum sciences and to contribute to the growth of the research group.

I was born and raised in Santiago, Chile, at the lower slopes of the Andes mountains. As a child I enjoyed spending time in the Chilean Coastal Range, land of eared doves, and the summer trips to the warm and arid northern beaches as well as the seaweed-covered freezing waters of the humble Dichato.
I got an early passion for Physics reading S. Hawking’s outreach books, and later through many university teachers.

Manuel Muñoz Arias
Postdoctoral fellow
Academic background
I completed my PhD and master degrees under the supervision of Ivan Deutsch at the University of New Mexico and the Center for Quantum Information and Control (CQuIC). My research focused on fundamental questions of the nonequilibrium dynamics of collective spin models, such as, dynamical and excited state quantum phase transitions, classical and quantum chaos, and out-of-equilibrium phases of matter. And at the same time in proposing and investigating quantum feedback control protocols for the realization of these interesting dynamics in an otherwise trivial system. Before this I completed my bachellors degree at the Universidad del Valle in Cali, Colombia, thinking about effective descriptions of ultracold atoms in tilted one dimensional optical potentials.

I developed an interest for natural science (engineering, geology, chemistry and most particularly physics). These interests led me to undertake a B.Sc. in physics and now a M.Sc. with Pr. Alexandre Blais.
When I am not studying, I like to listen to music and create it. I also like to practice a large range of sports; hockey, hiking, skiing, cross-country skiing, badminton, volleyball, and running. Some of my other interests include gardening, travelling, and philosophy.

Simon Richer
MSc student
Hello, my name is Simon Richer and I’m from Chicoutimi, a town north of Quebec City. As a child, I had many questions about the natural world around me. So I was inclined to learn a natural science. My father passed on his passion for physics to me. I naturally went on to a bachelor’s degree in engineering physics and now a master’s degree in physics. When I’m not studying, I love sports like judo, climbing, spike ball and hiking.
