Dr Corliss Sio is awarded a 2023 Dorothy Shoichet Women Faculty In Science Award of Excellence

Assistant Professor Corliss Sio is the recipient of a 2023 Dorothy Schoichet Women Faculty in Science Award of Excellence. 

The award was created to help early career female faculty focus on reserach and is awarded in any of the physical or life sciences, computer sciences or mathematics within the Faculty of Arts and Sciences. With the new GEMINAE lab being built in the Department of Earth Sciences, the awards teaching release will let Professor Sio invest time to get the lab running smoothly.

Special Seminar October 26 at noon – Professor Jay Ague, Yale University: The Oxidation of State of Arc Magmas and Why it Matters

Professor Miriam Diamond will present a talk “Can We Reduce Inevitable Exposures to Chemicals of Concern” at the Occupational and Environmental Health Seminar on Oct 12. Registration required.

About this event:

What: Occupational and Environmental Health Seminar

Speaker: Dr. Miriam L. Diamond

When: Friday October 13, 2023 from 12:10 to 1:00pm (ET). Please click here to register.

Dr. Miriam L. Diamond will present on “Can We Reduce Inevitable Exposures to Chemicals of Concern?”. Please see below for additional details and to register.

Title:  “Can We Reduce Inevitable Exposures to Chemicals of Concern?”

Populations are inevitably and inequitably exposed to chemicals of concern which is causing population-wide adverse health effects. The inevitability of exposure comes from basic thermodynamic theory coupled with high chemical production volumes and human activities. Failure of chemicals management is the root cause of population-wide adverse effects due to, for example, the growth in chemical production and proliferation in the number of chemicals produced. I will present four reasons for, and offer five solutions to redress this failure, ranging from promoting hazard and not risk assessment to putting a hard cap on chemical production.

Presenter: Dr. Miriam L. Diamond

Miriam L. Diamond, a professor at the University of Toronto, has advanced knowledge of chemical emissions, their transport processes, and resultant human and ecological exposure, and chemicals management policy. This work has been published in over 200 peer-reviewed articles and chapters, in addition to receiving media attention. Diamond is an Associate Editor of the journal Environmental Science and Technology, was the co-chair of the Canadian Chemical Management Plan Science Committee from 2017 to 2021, is the Vice-Chair of the International Panel on Chemical Pollution,  and is the chemicals and waste member of the Scientific and Technical Advisory Panel of the Global Environment Facility. She is a Fellow of the Royal Society of Canada, and the Society of Environmental Toxicology and Chemistry.

Congratulations to Nelson Roman Moraga, recipient of the 2022/23 Laurence Curtis Outstanding Teaching Assistant Award in Earth Sciences. Nelson is a Chilean economic geologist with five years of working experience in the mining industry, working as exploration geologist, mine geologist, geochemist and geometallurgist in various companies. He got HBSc and MSc degrees in geology at University of Chile, and currently he is a third year PhD candidate in Earth Sciences at UofT, in Professor Dan Gregory’s research team. His research aims to understand the source of metals, metallogeny and main geochemical features of the orogenic gold deposits in Yukon, Canada, through the study of sulfides and gold alloy in these systems.
