We are continuing a series of articles in which we would like to introduce you to our leaders at MSD BeLux, to get to know what drives them in their roles, what it’s like to lead at MSD BeLux, and what it’s like being part of a company with such a significant impact on the world.

Finance serves as an integral part of our leadership team as they analyze every day financial activities and provide advice and guidance on future finance plans. They are the root of all major business decisions, and their role is crucial to the success of any organization.

But what makes our Finance Lead, Rietja so passionate about financial affairs?

“I enjoy working within Finance as it touches all parts of the organization, providing a large diversity in the topics that we are involved in, and having both a short- and long-term focus. Together with my team we aim to provide the best possible support to our business stakeholders, partnering together to ensure that company resources are both optimally deployed and accurately reported. I am energized when I see what the power of a strong team and collaboration can accomplish together.”  

I feel supported by our company’s values and ways of working, which include the respect of others and embracing diversity & inclusion.

“I have always worked within Finance and Pharmaceuticals, however I sought to broaden my experiences by supporting different parts of the organization, from early-stage Research to late-stage Development, Production and Sales. In addition, I worked at different levels of the organization, currently within a local subsidiary but previously in Regional and Corporate positions. I have also had the opportunity within MSD to work in 5 different countries, gaining different cultural experiences. I moved to Belgium and joined the team almost 2 years ago, and despite COVID restrictions I became quickly integrated within the team.”

At MSD, we are committed to investing in personal growth and development. It is important to be open to trying something new, and to experiment, learn and adapt as you do. Continuous learning is not only important, but it also keeps things interesting!

“I take this topic seriously, and I would encourage people to have regular development discussions on this. Not only with your direct manager, but also actively seek feedback from others, and leverage one of the number of mentoring programs that are available within MSD. It helps to be clear in your career aspirations, to identify the optimal developmental actions to focus on and best prepare you for the next step.

It’s important to continuously build your portfolio of skills and experiences. I have sought to diversify my career by supporting different parts of the organization, at different levels, and in different countries. Each new environment helped me to broaden my knowledge, experience, and skills.”

We will continue the series with more interesting stories from our top leaders. So, stay tuned!

Katrien De Vos heeft op maandag 1 mei de leiding van MSD Belgium & Luxembourg overgenomen. Ze neemt hierbij het roer over van An Cloet, External Affairs Director bij MSD Belgium, die de functie de afgelopen 6 maanden ad interim uitoefende.

Voordat Katrien De Vos bij MSD aan de slag ging, bekleedde ze meer dan tien jaar diverse nationale en internationale functies bij AstraZeneca.

Ze zetten zich elke dag in om belangrijke uitdagingen op het gebied van volksgezondheid aan te gaan door innovatieve geneesmiddelen en vaccins te ontwikkelen. Ik ben ook verheugd om opnieuw in België aan de slag te gaan: terwijl ik aan de slag was in het buitenland besefte ik hoezeer België wereldwijd bekend staat om zijn academische onderzoekscentra, universitaire ziekenhuizen en farmaceutische industrie, die samen een wetenschappelijke expertise van onschatbare waarde bieden. Ik kijk ernaar uit om met het hele Belgische gezondheidsecosysteem samen te werken om innovatie toegankelijk te maken voor zoveel mogelijk patiënten,” zegt Katrien De Vos.

Meet our leaders at MSD BeLux: Dr. Laurent Viérin, Country Medical Director

We are starting a series of articles in which we would like to introduce you to our leaders at MSD BeLux, to get to know what drives them in their roles, what it’s like to lead at MSD BeLux, and what it’s like being part of a company with such a significant impact on the world.

Medical Affairs colleagues are the face of the company.

Since they interact with the medical community, the Medical Affairs (MA) colleagues are the face of the company, and their scientific expertise helps them in these interactions. Our MA Department only includes professionals with a strong scientific background, often complemented by a Ph.D.

Our MA colleagues are the pre-eminent scientific experts in their therapeutic areas. With the knowledge and expertise they have on our products, the disease, and the broader environment, they stay true to our mission “to communicate and generate medical evidence to help those responsible for healthcare decisions make informed choices that improve access and health outcomes for patients”.



We bring value to the different development phases of our medicines.

The MA department’s main activities span from the clinical development of our molecules to post-approval activities. The team interacts with many internal stakeholders, such as the clinical trial organization colleagues, the regulatory departments, and the pharmacovigilance teams, as well as the market access and commercial groups. The MA team is one of the departments that work most intensively with all other departments in the MSD organization.

Because our focus is on scientifically/medically driven conversations and activities, we interact with all external stakeholders, such as healthcare professionals and other decision-makers for whom science matters, and the in-depth knowledge of our products is important to their decision-making.

“We develop medicines and vaccines that can potentially save and improve the lives of so many people. When thinking about our rich pipeline that addresses all of these unmet needs, I feel a sense of responsibility to bring those innovations to the people that need them. Our goal as a department is to drive and support the progress of our pipeline products towards ultimate access for patients.

Working day after day in collaboration with other motivated colleagues that strive toward that objective is, I must say, very rewarding and gives me a strong sense of pride.”

Meet our leaders at MSD BeLux: Philippe Decerf, Business Operations Lead

We are starting a series of articles in which we would like to introduce you to our leaders at MSD BeLux, to get to know what drives them in their roles, what it’s like to lead at MSD BeLux, and what it’s like being part of a company with such a significant impact on the world.

Business Operations (Bus.Ops.) serves as a guide for our company. This unit acts as a fail-safe, limiting our risks and helping the company avoid operational problems.

Our Bus.Ops. team oversees many processes that allow this company to function effectively. We prepare for change and seize opportunities. Imagine what would happen:

  • if our products were no longer available on the market or could no longer be delivered to our customers (ONE, wholesalers, pharmacists, etc.) on time?
  • if some of our activities did not comply with the laws or MSD standards? What would the impact in the media be and, more importantly, what would this do to the image that our customers and patients have of MSD and its products?
  • if we had no knowledge, no contact points with the hospitals, and could not respond to their needs in an ever-changing hospital environment?

The Bus.Ops. team aims to become a hub of excellence to deliver the best customer experience internally and externally!

MSD provides the environment to help me shape my career and reach my fullest potential.

Long story short, I have been working at MSD as the Business Operations Lead for almost three years now. I started my career in this company, 25 years ago, as a medical representative. After five years, I became a sales manager covering many different therapeutic areas and leading several teams in primary care and hospital care. During this 10-year period, MSD gave me the opportunity to follow many training courses, and in project management (Six Sigma, etc.) specifically, which allowed me to engage with project management on both a local and regional level. MSD puts you in charge of your career!

My leadership style is both supportive and challenging.

“I don’t like the idea that there is one leadership style that’s better than the other. I think someone’s leadership style needs to align with the team, the individual, and the task. Anybody can be an expert or leader in their area. As a leader, you need to be supportive, which can be participative and/or directive. I prefer to talk about values and beliefs. I particularly love to challenge the status quo and use humor and respect in my interactions. I like processes, and I enjoy reviewing them to make things simpler, clearer, and more organized.”

This leader works to ensure diversity and inclusion is visible in everything we do

Deepak Khanna, president, Europe and Canada, demonstrates how “diversity is a fact, but inclusion is an act”

December 13, 2021

.st0{fill:#00857C;}

Inclusion in the workplace is said to be key to employee retention. And research shows that hiring a diverse and inclusive workforce contributes to higher revenue growth, greater readiness to innovate and the increased ability to recruit a diverse talent pool.

“For our company, diversity and inclusion is something that everyone is really passionate about and something I like to see in everything we do."

Deepak Khanna

President, Europe and Canada

Khanna oversees about 6,000 employees in our company’s commercial operations across Europe and Canada. These operations include sales, marketing, pricing and access, and external affairs — which can range from the process of getting our medicines approved to making them available to patients, governments, payers and health care providers.

“As a leader, I work to ensure that we are reaching a diverse set of patients who can benefit from our innovations, and that patients of all ethnic and socioeconomic backgrounds have access to them,” said Khanna.

When it comes to our leadership programs, how we interact with customers, how we support inclusion in our communities, and our external communications such as online messaging, Khanna ensures we uphold our commitment to diversity and inclusion.

“It’s not only important that diversity and inclusion is visible at our company, but it is also important to ensure that our medicines are available and affordable to patients who need them all over the world, whether they’re rich or poor. We also work to make sure health care literacy is made available, so people understand what their medicines are, what their health care system is and how to best navigate it,” he explained.

“Diversity has always been a part of my life”

Diversity and inclusion has been a passion of Khanna’s from an early age.

Khanna, who is of Indian descent, was born in London and moved to Canada when he was about two years old. After spending four years in Canada where he learned to speak French, his family moved to Chicago and then finally to California where he spent much of his teen and early adult years.

“I’ve grown up around people from different cultures and backgrounds so for me it is just a natural way of life and a natural way of working,” said Khanna.

Once he joined our company, Khanna held various roles that gave him the opportunity to travel the world, where he further learned to appreciate different cultures and backgrounds.

“Diversity of cultures is something that I’ve always been fascinated by because there’s always something to learn from other people, how they do things and how they approach things,” said Khanna. “The ability to appreciate other cultures and diversities of all kinds including race, gender and religion, is what helps us all get a broader perspective on work and life.”

A role model in diversity and inclusion

Khanna’s diverse background and exposure to different cultures and values were influential in developing his passion for diversity and inclusion. But most of all, one person in his life truly inspired him: his great uncle.

Khanna’s great uncle was a physician and a general in the Indian Air Force. From the time he retired to when he was around 85 years old, he would still open his home several days a week to treat the poor people in his neighborhood for free.

“I’ll never forget that. He just said, ‘We are privileged, and I want to make sure for as long as I am able that I continue to treat any person around the neighborhood I can. It doesn’t matter how much money they have, I want to make sure they have access to medicines and that I can help them,” said Khanna.

Khanna kept the lesson from his great uncle to support others that are less fortunate.

“I did learn from him the importance of giving. It doesn’t matter who you are, you should have access to treatment and medical care, and I try to translate that to what I do in my role.”

Diversity is a fact, but inclusion is an act

Throughout his time at our company, Khanna has taken to heart something a team member once told him: “diversity is a fact, but inclusion is an act.”

In other words, we can measure diversity with numbers, but leaders also need to know how to leverage diversity of thought and culture into something more.

“What I’ve learned is focusing on diversity is important, but it doesn’t mean a lot until you figure out how you can get this diverse group of people to work together in the most effective way,” said Khanna.

He thinks it’s important to make sure people feel safe to speak up, and to always look for ways to make them feel welcome and comfortable in an inclusive environment.

“People could be scared to speak up because it could have an impact on them or they may think leaders don’t really listen, but the impact of that is we will lose the diversity of thoughts and beliefs that can make us a better business,” he said.

And Khanna believes that other point of views, perspectives and cultures give us the knowledge on how to best approach a business problem or challenge.

“That is what diversity and inclusion brings,” said Khanna. “Different and unique perspectives on how to do things in a very different way, keeping us fresh and nimble and able to respond to any challenges we have to face.”
