Vacancies: Post-doctoral Fellows for the Novel Entities Group

In collaboration with the Earth Commission, the University of Toronto School of the Environment announces opportunities for two Post-doctoral Fellows (PDFs) to join the core research team focussed on assessing Safe and Just Earth System Boundaries (ESBs) for Novel Entities. Apply by 24 June.


The Earth Commission’s second phase focusses on updating the Safe and Just Earth System Boundaries, building on  Rockström et al 2023 and other publications. The goal of this specific project is to advance the current understanding and implementation of strategies to stay within safe and just boundaries for novel entities, including chemical pollution.


The candidates will have either graduated with their PhD or be close to graduation, with demonstrated experience in multidisciplinary research. One candidate will be expert in biophysical/engineering aspects of novel entities, including but not constrained to fields of environmental chemistry and environmental and/or chemical engineering. The other candidate will be expert in areas of governance and sustainability transformations, including but not constrained to the fields of environmental science or political economy. Both candidates will need to be attentive to issues of equity and how equity can be brought about.

Area of Research and Description of Duties

The following are the areas that will be addressed by the PDFs, with exact subject areas to be divided by the two PDFs based on expertise and interest of each candidate:

  • Scan of methods that could be used to determine ESBs for a subset of novel entities. The methods that could be used include material flow analysis, life cycle assessment and other types of impact assessment methods.
  • Undertake “horizon scanning” of the literature to document present and future novel entities that are or could transgress either a Safe or Just ESB. This scan will add the broad context to the case studies of specific novel entities.
  • Undertake case studies of several specific novel entities to develop Safe (biophysically-based) and Just (according to interspecies, intra-societal and intergenerational equity) ESBs.
  • Consider transformation pathways that moves society from our current situation to within safe and just ESBs. This analysis could consider novel entities in broad categories and could also focus in on the case studies undertaken for the ESB evaluation.

Details of the Positions

Funding is available for at least 2 years at an annual net salary of $60,000 CAN commensurate with experience. The normal hours of work are 40 hours per week for a full time postdoctoral fellow (pro-rated for those holding a partial appointment) recognizing that the needs of the employee’s research and training and the needs of the supervisor’s research program may require flexibility in the performance of the employee’s duties and hours of work.

You will be supervised jointly by Professor Miriam L. Diamond (School of the Environment and Dept of Earth Sciences, University of Toronto) and Dr. Zhanyun Wang (EMPA, Switzerland). Start date is flexible but sooner than later is preferred.

How to Apply

Interested candidates are invited to submit their full CV, a cover letter describing their interest in the position and how their background aligns with the project’s goals, and examples of their published work. You must list three referees who can provide an arm’s length assessment of your professional expertise and performance. Please send your application to

Deadline is 24 June 2024 (extended from 1 May 2024).
