Rosalyn Yalow


Rosalyn Yalomw was a nuclear physicist. She developed radioimmunoassay (RIA) together with doctor Solomon Berson. RIA is used to measure small concentrations of substances in the body, such as hormones in the blood. Rosalyn Yalow and Solomon Berson tracked insulin by injecting radioactive iodine into patients' blood. Because the method is so precise, they were able to prove that type 2 diabetes is caused by the body's inefficient use of insulin. Previously it was thought that the disease was caused by a lack of insulin.

Dr. Yalow received the Nobel Prize in Physiology or Medicine in 1977 together with Roger Guillemin and Andrew V. Schally.  In response to this, Dr. Yalow wrote a biographical essay about her life, influences, work experience and partnerships with other researchers. It is a very beautifully-written and impressive and moving history and it was published on the Nobel Prize website.  She describes for example, "hanging from the rafters in Room 301 of Pupin Laboratories (a physics lecture room at Columbia University) when Enrico Fermi gave a colloquium in January 1939 on the newly discovered nuclear fission."

In another phase of her life, while being newly married and taking two background undergraduate classes, three graduate courses in physics, serving as a half-time assistant teacher, as well as being an observer of another instructor so as to improve her own teaching skill, she received straight As in two of her classes and an A- in one. In response, the Chairman of the Physics development told her "That A- confirms that women do not do well as laboratory work."

Rumina Velshi

Rumina Velshi was appointed President and Chief Executive Officer of the CNSC in August 2018.

Ms. Velshi has had a long association with the CNSC, having been a Commission member from 2011 until her appointment as President and CEO.

Ms. Velshi has extensive technical, regulatory and adjudication expertise in the energy industry. Throughout her career, she has worked in various capacities at Ontario Hydro and Ontario Power Generation, the electrical utilities in the province. Ms. Velshi also previously served as a part-time Board member of the Ontario Energy Board, the economic regulator of the province’s electricity and natural gas sectors.

In February 2020, Ms. Velshi was appointed Chairperson of the Commission on Safety Standards (CSS), established by the International Atomic Energy Agency (IAEA), for a four-year term.

Ms. Velshi very actively promotes careers in science, technology, engineering and mathematics (STEM), especially for young women. Since joining the CNSC as President and CEO, she has launched a women-in-STEM initiative to consider ways to support women in STEM careers at the CNSC and elsewhere, and to further STEM education by working with interested partners. She has also delivered several international keynote addresses about breaking down barriers for women in STEM.

Ms. Velshi was one of the founding members of Canada's Women in Science and Engineering and currently serves on the Board of Directors of the Canadian Institute for Women in Engineering and Science (CIWES), an institute that advances education in the STEM fields worldwide through an international network of organizations, foundations and experts.

She has served as Vice-Chair on the Board of Directors of Scientists in School, a non-profit organization that offers STEM-focused workshops to more than 700,000 students each year. Ms. Velshi is one of 150 Canadian women whose stories are compiled in Your Turn, a book published to mark Canada's 150th anniversary and inspire the next generation of women leaders.

Ms. Velshi holds a Bachelor of Applied Science degree in civil engineering, a Master of Engineering degree in chemical engineering and a Master of Business Administration, all from the University of Toronto.
