What is your current job?

Staff scientist and university lecturer - I have two jobs. As a staff scientist, I work on fundamental satellite research for ongoing and upcoming missions. I am currently working on an optical navigation system for satellite rendezvous with asteroids. As a university lecturer, I teach students about the mechanics of space flight, simulating the motion of satellites, and the design of small spacecraft.

Why do you want to become an astronaut?

The biggest reason I want to become an astronaut is to be able to share the incredible space science being done with a large audience. As an astronaut, not only would I be on the leading edge of space research, working with the best minds in the world who are tackling science's most challenging problems, but I would also be able to serve as a voice for that research.

What motivated you to study in your field?

My love of satellites and spacecraft is rooted in the love of taking things apart to see how they work. I spent most of my youth disassembling and reassembling my toys; truth be told, I never stopped. Spacecraft are the pinnacle of complex machines. Being able to study them, take them apart, build them back up, and study to design my own was my main focus when it came to choosing a field to study.

Think back to a teacher who had a positive impact on your life. What did she/he do to influence you?

I was fortunate to have many exceptional teachers throughout my education. My high school math teacher does stand out – an eccentric, brilliant man with a love of all things math. The level of excitement he brought to the classroom was infectious. What set him apart was that nearly every lesson he taught involved some kind of story – he managed to turn math into story time and wove the lesson around his tale. Not only was it effective, but it also gave the lessons meaning. Whenever I teach, I always try to give my lessons that same kind of meaning because of him.

What do you like best about your job?

The part of my job I like the best is that I am constantly learning. Every problem I tackle is something completely new that has never been solved before. To solve these problems, I need to be constantly researching new and old techniques and discoveries to collect the necessary tools.

Which living person do you most admire? OR Who are your heroes in real life?

Chris Hadfield – I always grew up with a deep admiration for astronauts, but Col. Chris Hadfield managed to bring space exploration to such a wide audience using such diverse media. His abilities to communicate and engage are tremendously impressive, and his dedication to Canada and to space exploration is inspirational. If I aspire to do anything, it is to live up to and extend the legacy he and other Canadian astronauts have fostered.

What is your favourite sci-fi movie?

The Empire Strikes Back.

What is your motto?

If it's worth doing, it's worth doing your best.
