I was born in 1990 in Daejeon, South Korea. I first came to Vancouver when I turned 16 for a short term visit. Having liked the student life in Canada, I decided to stay longer. In 2009, I moved to Waterloo to attend university and I experienced a true Canadian winter. With the help of a thick winter jacket, I managed to survive and graduated with a Bachelor’s Degree in Applied Science (Mechanical Engineering) from the University of Waterloo in 2016. Currently, I am still struggling with winters here while working on the completion of my Master’s Degree.   

Research interests

My research area is focused on developing the time optimal trajectory generation for a 5 axis laser drilling machine. Specifically, I am dealing with a percussion laser drilling process, which involves a complete stop of laser head motion in between the points to open up a hole. Due to this stop and go nature, it resembles a well-known Traveling Salesman Problem of combinatorial and optimization in Mathematics. By applying some of its theories and algorithms to my application, it is possible to generate trajectories with less travel time. The project is supervised by Dr. Kaan Erkorkmaz and Dr. William Cook in collaboration with Pratt & Whitney Canada.

Hobbies and activities

In my spare time, I train in MuayThai. I also enjoy good food with great company.
