About Jeanne Guérin Certified Ergonomist CCPE

My Story

Image of Jeanne Guérin in front of a plane

Around the age of 12, I saw a commercial plane pass over my head and I said to myself that one day I would be on this plane. I did not know that this vision would propel me into orbit!
Slowly over the years my choices instinctively pushed me towards my goals. At 16, I experienced a first flight in a Cessna, at 20 I went on a charter flight to France, my first commercial flight! Dream number 1 fulfilled!

I also began to dream of space and to contemplate an astronaut career. It was rather difficult at the time given the competition with Marc Garneau! So I had to rethink my strategy … A career in Industrial Design might allow me to work in the aerospace field? At 25 I was doing my one year baccalaureate project with Canadair / Bombardier (a first for the Design Department of U of M), to then be hired for designing the interior of the first commercial jet in Quebec.

My passion continued to push me higher, this time towards a master in Ergonomics for a context of microgravity. Yes, I was drawn to space and I was going to approach it one way or another! So I decided to do a master’s degree in ergonomics for the space sector. Naturally, the field of space ergonomics in Canada did not exist and there was no training in this field since Canada is specializing in robotic systems like the Canadian arm or the manufacture of satellites which did not require human interactions. In fact, apart from NASA in the United States, the human factors domain for space was really very limited.

I had to do a master’s degree with research credits, which was not so simple when Google didn’t exist! I was even advised to do a master’s degree in physiotherapy to find a good job! To which I replied that I already had a good job! Bombardier trusted my abilities by giving me the title of Human Factors specialist during the development of the cockpit of the Global Express business jet. What an opportunity! I finally finished my master’s thesis entitled “Ergonomics in the design processes applied to the context of microgravity in a space environment” at 34 years old. Dream number 2 fulfilled!

A year later, I found myself working at Boeing where I spent several years contributing to the design of the cockpit and the interior of the new 787 aircraft, accumulating invention patents, learning how to fly, again I had a lot of fun! On the other hand, without American citizenship, there was little chance of working at NASA. But time does it right. The space sector finally opened up to private industry which began to develop space tourism. As soon as I could, I applied to Blue Origin even though there was no post for Human Factors ergonomics. After a quite exhausting interviews, I got the job and worked to put humans into orbit. Ultimate dream fulfilled!

I cannot say that it was done quickly or easily but it is not only the goal that counts it is also the journey to get there!


Today, I will explain why ergonomics is a fundamental health discipline.

First let’s talk about injuries caused by practices that are not conforming to the scientific principles of ergonomics. Musculoskeletal Disorders or MSDs and repetitive work-related joint injuries are injuries to soft tissues such as tendons, nerves and muscles. About 34% of all work accidents are musculoskeletal in nature, which is significant and costly.

One of the causes of MSD-type injuries is due to an inadequate design of the workstation. It could be that the dimensions are not adapted to the stature of the various people who use it or due to the lack or improper workstation adjustments, causing the user to maintain difficult postures, which in return create strain on the muscles, fatigue and inflammation. If we add repetitive movements over a long period of time, and even worse, the use of force to perform the task, we end up with a high risk of developing musculoskeletal disorders for the person assigned to the task.

That’s not all, if the environmental conditions of cold, heat, light, vibration and noise are part of the equation, it is possible that normal working conditions will be degraded to an unhealthy level.

Mental health as strange as it may sound can affect physical health. Indeed, stressful situations can amplify MSDs by causing inflammation and delaying recovery and return to work. Mental loads, stressful work situations, circadian cycles and overtime can lead to mistakes that can put at risk the health and safety of the workers.

The discipline of ergonomics is often overlooked because many times, the injuries are not felt at the onset of the faulty work task. The MSDs are often caused by an accumulation of minor symptoms over time. The injuries often appear after a period of time, making it difficult to associate the faulty process to  the source of the pain. The importance of following good ergonomic practices is often ignored based on misconceptions and lack of knowledge. Ergonomists must take the time to educate people about the importance of following ergonomics standards. Dr Marras, a recognized spine expert explains back injuries that appear suddenly for unknown reasons, by the accumulation of micro scars on the discs which, by accumulation, prevent blood flow through the discs. Blood circulation is necessary to keep discs healthy. Lifting excessive loads or with improper postures cause these micro scars over time, leading to injuries that are often very difficult to heal. Following good ergonomic practices is essential to maintain good health in the long term.

With more than a third of all work accidents being musculoskeletal in nature, it is clear that ergonomics must be considered a fundamental discipline for the health of users in the workplace and in life in general. In addition, an injury costs an average of $ 35,000 to the employer and the average compensation time is 62 days, which gives reason to reflect on the importance of ergonomics as being an essential driver for the health of business operations.

The costs associated with injuries are not just business-related. The injured employee will experience a decrease in income; not all care may be covered by insurance. Their lifestyle can be affected, for example, by the inability to return to their favorite or even basic activities. This burden weighs heavily on their self-confidence and can create anxiety leading to the inability to return to work.

Ergonomics affect the health and safety of all of us in many different ways. Let’s be aware of ergonomics best practices to keep us healthy for a long time.
