Knight's sixty-year-old father, John, a 'self-proclaimed nerd' who loved everything to do with space and aviation, was diagnosed with an aggressive form of the neurological condition amyotrophic lateral sclerosis (ALS) in 2019. He died just six months later, one of three siblings in his family taken by the devastating disease.

At the time, Knight was a 19-year-old undergrad studying chemistry at Carleton University with no concrete plans for his future. He admits he didn't really know how he could be part of a solution to ALS, but felt strongly that he had to do something to help people with the disease that had been so prevalent in his father's family.

ALS is a neurological condition that affects motor neurons — the wires that connect the brain to the muscles. Approximately 4,000 Canadians are affected. The majority will survive between two and five years after being diagnosed. Some, like John Knight, survive for less than a year. Others live beyond five years.

Among his courses at the time was one taught by Maria DeRosa, a chemistry professor and researcher who is now Dean of Science at Carleton. Her overwhelming support and sympathy, along with her approach to teaching and to students, made Knight think she was someone he would like to work with to continue his studies.

He became interested in her work, which includes the use of aptamers. The synthetically produced single-stranded DNA molecules can selectively bind to any target they are designed to bind to, including specific proteins. That makes them an important research tool. Aptamers have a long list of potential applications — including in healthcare.
