Everyone welcome!   

Description of Event

This event includes the Dr. Harold B. Stewart Memorial Lecture and Research Showcase of Biochemistry students. The latter features 2 poster sessions highlighting the research progress at Western University of i) first-year Biochemistry graduate students (moved to another day) and ii) undergraduate students in the fourth-year Biochemistry research project courses.

The Stewart Lecture honours Dr. Stewart, a former Biochemistry Chair and Dean of Graduate Studies at Western, and is made possible by the Stewart Family Donation (via Dr. Ann Stewart, daughter of Dr. Harold Stewart). The Lecturer, a Biochemistry alumnus/alumna, is chosen by current Biochemistry graduate students.

The event is open to students and researchers from Western and affiliated institutions.

The event will benefit Western's graduate students in the following ways:

  1. Graduate students can attend the Dr. Harold B. Stewart Memorial Lecture given by Dr. Ventzi Hristova. She will share her career experiences working in the biotechnology sector. She represents an inspirational role model for students, given that she graduated from the Biochemistry PhD program and is now a Team Leader at AstraZeneca, a biotechnology company.

  2. Important skills in preparing and communicating research posters, as well as answering questions, will be acquired by those students presenting their work. For many students, this event will be their first formal poster session.

  3. Graduate students will learn about research in the Dept. of Biochemistry and interact with other researchers at the posters, allowing excellent opportunities for collaboration and exchange of ideas.

This event will expand the scientific horizons of graduate students in Western's biomedical/science programs. The event represents a critical starting point for future research lectures and poster sessions that these students will experience; such sessions are universal communication tools at scientific conferences.

Biography of Dr. Stewart

photo of Dr. Harold StewartDr. Harold B. Stewart was born in Chatham, Ontario in 1921 where he attended primary and secondary school before studying Medicine at the University of Toronto. Following graduation with Honours in 1944, Dr. Stewart was enlisted as the ship’s doctor on the HMCS Puncher, a troop carrier in the Canadian Navy. ​

After the war, Dr. Stewart returned to Canada and obtained a PhD in Biochemistry at the University of Toronto for studies on “The action of chloramine-T on alpha-amino acids and the purification and analysis of cytochrome C”. During his PhD training, Dr. Stewart met Pauline Blake, who was seeking a Master’s degree in biochemistry, an uncommon qualification for a woman at that time. They married in 1950 and immediately left Canada to pursue further studies at Cambridge University (UK) where Dr. Stewart had obtained a scholarship. Dr. Stewart was awarded a second PhD at Cambridge for “Studies in Ketosis”. ​

In 1955, he accepted a faculty position in the Department of Biochemistry at the University of Western Ontario. He became Head of Biochemistry in 1965 at a time of great growth Western and was responsible for the recruitment of many new faculty. In 1971, Dr. Stewart returned to Cambridge for a sabbatical year before assuming the position of Dean of Graduate Studies at Western, a position he held until he retired and became professor emeritus in 1986. Dr. Stewart passed away in 2009. ​

In his distinguished career, Dr. Stewart was committed to higher education and through his efforts many young people have entered academia and gone on to develop new knowledge and to support others in their own learning.
