Currently looking for a full-time position starting as early as winter 2027!
About Me
I am a PhD candidate in electrical engineering at Université Laval, supervised by Jean-François Lalonde and Yannick Hold-Geoffroy.
My research focuses on spatial lighting estimation: recovering the full HDR lighting at any point in a scene from ordinary images and videos. I am currently a research intern at Meta Reality Labs, working with Chengan He. Before that, I interned at Eyeline Labs with Julien Philip, Li Ma, Mingming He and Paul Debevec, and at Adobe with Zhixin Shu and Yannick Hold-Geoffroy.
I describe my research aspirations as “placemaking”: I want to understand environments as people perceive them, and build tools for the people who design and live in them. This vision drives my work on lighting estimation, and was strengthened by collaborating with architecture students.
Outside of research, I love reading and making things; you'll find my favorite books and some of my renders below.

Reading
I love finding books in used bookstores. There are so many ways to choose the few books that can be read in a lifetime, and I find beauty in the happenstance of which books made their way to the place and time I visit. Recommendations are always welcome!
What I'm Reading Now
-
The Man Who Mistook His Wife for a Hat
Though proven to be somewhat embellished, Sacks's clinical account forces you to question your relationship with your own mind.
-
Sarah Bakewell has a way of making philosophical history such a delightful read (or listen, as I'm listening to the audiobook).
-
A nice novel to unwind with before falling asleep. Bancroft's similes are powerfully visual.
-
A beautiful and detailed history of all of human civilization until 1815, Will and Ariel's account will remain on my current reading list for a few more years. I'm now on the fourth volume, and marveling at every word.
A Few of My Top Books
-
My top book of the last year: the survival story of Shackleton's crew is deeply engaging, showing how perseverance and good leadership can make life tolerable in the harshest conditions.
-
Rovelli's enchanting prose makes science reading a highly poetic experience. Though all of his books are worth reading, The Order of Time struck me as the best entanglement of literature and scientific facts.
-
A phenomenological analysis of the place of light and darkness in culture and modern identity.
-
The Biggest Ideas in the Universe
Carroll isn't scared to use precise language and equations to explain scientific concepts that are usually skimmed over and conveyed through intuitive analogies, an approach I found refreshing.
-
In Search of Memory is my search for interdisciplinarity. I love to immerse myself in science of all kinds, and this book recounts, in precise detail, the discovery of the short-term modulation of neurons that underlies memory.
-
A thoroughly detailed account of how cells can exhibit computational mechanisms. The idea of chemical diffusion as time-dependent signal transmission is a powerful one that has stayed with me since reading this book.
-
Gleick is clear in his scientific explanations, while remaining keenly aware of science's cultural impact. His book on information follows Shannon's theory, keeping a nice balance between abstraction and physical relevance.
-
Philosophy is sometimes a frightening subject to approach as a science person. However, Bakewell makes it painlessly accessible, following Montaigne's life as a way into his philosophy.
-
Code breakers invariably follow code makers, and the latter then respond with stronger codes. Singh traces the history of codes from the first written words to current-ish cryptography (the book is from 1999).
-
I wouldn't have thought urbanism could be such a relatable subject, but Montgomery hooked me by saying “The solution lies in appealing to pure self-interest,” promising a view of urban design as much for the environment as for the individual. It is the book that now makes me carry a pen whenever I pick up a book.
