In 1966, Packham rejoined the Department of Biochemistry at the University of Toronto, where she remained for the rest of her career. She became a full professor in 1989. From 1966 to 2003, she held a visiting Professorship in Pathology at McMaster University, where she continued to work with Mustard’s team. Her research examined the biochemistry and physiology of blood platelets and their role in hemostasis and arterial thrombosis.[2]

After retiring, Packham continued active research as Professor Emerita for six years. She also wrote a history of Biochemistry at the University of Toronto[4] and a brief biography of Fraser Mustard.[5][6]
