RSI's Greg Paoli

Greg Paoli

As RSI’s Principal Risk Scientist and COO, Greg Paoli is currently working with a broad spectrum of clients in the public and private sectors, with the greatest emphasis on the development of new approaches to transform regulatory systems to be more “risk-based” at multiple levels: how senior decision-makers process risk information and make the “tough choices” in regulating health and safety, how an organization can optimize its resources across a diverse mandate to maximize total “portfolio-level” risk reduction, and how to operationalize key resources like the scheduling of inspections when faced with thousands of inspection targets, but not enough resources to inspect all of them.

RSI's Donald Mattison

Dr. Momoli is the acting Practice Lead for Chemical and Product Safety at Risk Sciences International, as well as an adjunct professor in the School of Epidemiology and Public Health at the University of Ottawa.


Providing expertise is a great responsibility. It requires a sense of commitment and a desire for positive outcomes. Expertise also requires the right combination of qualifications and experience. Risk Sciences International is not unique in that they did not invent the quest for the best talent. They are, however, committed to remaining among those who constantly strive to attract and retain the best and most skilled staff.

Ultimately, guidance is a balancing act, one that RSI takes very seriously.

The list of organizations, companies, and governments above in no way denotes or implies support or endorsement by these entities. The list is intended as an indication of the breadth of work led and undertaken by Risk Sciences International staff.

Risk cannot be a proprietary battle. One person's discovery can mean another person's safety or survival.

RSI scientists are committed to publishing peer reviewed articles, not for the recognition, but in the hope, the sincere hope, that our ideas can contribute to the greater good.

During these unique times during which physical distancing is affecting all aspects of society and our economy, RSI is well prepared. Since its inception, the company has been equipped and trained to deliver results remotely. We use virtual meeting applications extensively, as well as virtual training and webinar software. The nature of risk management is such that all RSI staff have always been a moment's notice away from intervening in urgent matters.

Important: Our sincere thanks go out to all first responders worldwide who have so bravely helped us all to face this unique challenge.
