Discord server:

I realize I work better when I am surrounded by people who are working, and this is a culture I actively try to spread. If you want to be part of this, feel free to join my Discord server here!

Research and contact:

If you are interested in graph theory, combinatorial reconfiguration, parameterized complexity, or related areas, feel free to reach out at relsabeh (at) uwaterloo (dot) ca. I am always happy to discuss interesting problems and collaborations, and I often have open problems that could benefit from additional perspectives!

Some of my current interests:

• Collecting stickers for the FIFA World Cup (~940/980 collected so far)

• Accessorizing my scooter Jorjio

• Finding new spots to work at, weather permitting

• Working on my book, "The Room They Call The World" (tentative name)
