Eelco Ebbers, PhD


CEO

I was always fascinated by organic chemistry. Understanding small and large molecules intrigues me still. Together with my entrepreneurial interest, this led to co-founding Mercachem in 1997, together with Frank Leemhuis. It has been a great adventure developing Mercachem, MercachemSyncom and now Symeres, and the journey continues.

“Entrepreneur in R&D business models with the goal to provide new innovative solutions for development of new medicines”


Frank Leemhuis, PhD


Head of Corporate Development

As a chemistry student, I wanted to combine research with my entrepreneurial spirit. The inception of our company in 1997 was the perfect combination for me and the start of a great journey. I still look forward to fulfilling our client’s R&D goals to find novel therapies for patients.

“It is the set of the sails, not the direction of the wind that determines which way we will go.”


Guillaume Jetten


CFO

I am CFO of Symeres since 2017. Before that I served as CFO for Galapagos and for Wolters Kluwer Health, as well as in several other senior financial roles. I am holding a masters title in economic sciences and I am a registered accountant.

“What I love about working at Symeres is the enthusiasm for creative science and drive to make clients' projects successful”


Marleen Dolman, BSc


Communications and Marketing

Trained as a chemist, I realized I love seeing more aspects of a company than just the scientific side. Communication allows me to go everywhere, talk to everyone. Outside work, I love writing fiction, mainly science fiction, where I use my background in science for interesting worldbuilding.

“Nothing in life is to be feared, it is only to be understood” - Marie Skłodowska Curie


Sascha Hartmann, MSc


Director Business Development

For me the fascination of chemistry is in its pivotal role connecting scientific disciplines from fundamental understanding to commercial application. Here at Symeres is the perfect place to experience this dynamic. In my spare time I enjoy walking, campervanning and exploring places with my family.

“Everything is theoretically impossible, until it is done.” – R. A. Heinlein

With a managerial background in PR&D, I joined Syncom in 2010 as COO. After forming MercachemSyncom and Symeres I currently manage the Symeres site in Groningen. In my free time I enjoy sports -European style football in particular-, travelling and playing strategic board games with my family and friends.

“Knowledge is a treasure, but practice is the key to it”


Roger McDonald


Director Business Development

After spending some time post University working in academia, I moved into the commercial world of sales. I’m a keen cyclist, happiest going uphill and in front of my Dutch colleagues! As a lifelong Blackpool FC supporter, I am keen to remind them that it is tangerine, not orange…

"It's only a hill."


Nori Morita


Director Business Development

I got in touch with Drug Discovery by accident in the nineties and fell in love with the adventure of exploring un-knowns. It is my biggest pleasure to find possible solutions for our customers which will eventually lead to better Quality of Life for many people.

“identify unknown-unknowns, make them known-unknowns.”


Chris Teleha, PhD


VP Business Development CMC US

I got into Chemistry when Paper Science was just too ‘Applied’ Science for me. I enjoy devising mechanisms for by-products and retrosynthesis of new molecules. Although I like fixing things at home, one can’t be more fundamental in understanding of how things work than through chemistry!

“I like it when I complete a New York Times Sunday crossword puzzle without help from the internet.”


Luc van Hijfte, PhD


Senior VP Drug Discovery

As a kid, I was intrigued that pills can cure disease. Since then I wanted to get involved in the development of new medicines. Now, years later, I look back with great of satisfaction to my various contributions in drug discovery, something I continue to do with passion and energy.

"Without chaos nothing evolves, without structure nothing exists…"


Rutger Folmer, PhD


Director Medicinal Chemistry

I am passionate to help progress drug discovery projects, irrespective of maturity or complexity of the program. I feel strongly that constant focus on the quality and reliability of the data is the differentiating aspect of progression. Here is where I want to make a difference – together with my team.

“There are no secrets to success. It is the result of preparation, hard work, and learning from failure.” -Colin Powell


Anita Wegert, PhD


Director Medicinal Chemistry

I am an organic chemist and a medicinal chemist by heart. Already at the age of 16 I knew that I want to become a researcher. At Symeres, I am part of a creative and open minded team, which even allows crazy ideas. This is a very refreshing experience.

“Look out for the strange, surprising and unanticipated in your data, this can make the difference.”


Bas Dros, PhD


Director of Chemistry

There is more to life than chemistry, but if I had the chance to do it all again, I wouldn’t change a thing.

“The more you know, the less you realize you know.”


Erik van Echten


Director of Analytical Chemistry

Performed my first chiral HPLC separation somewhere in 1989, many more in the years that followed, but seeing those two peaks appear has always put a smile on my face. I’m proud to see that I have been able to pass on this “fingerspitzengefühl” to the next generation.

“You don’t have to be a farmer to be excellent in your field”


Tommi Meulemans, PhD


Director of Chemistry

Just graduated from high school, I wanted to cure people as a physician, but decided that as a chemist you are one step ahead in the curing chain. Now, finding the most efficient synthesis routes or designing a molecule that fits the client’s needs can make my day.

“You do or do not, trying is not option” (Yoda)


Peter Molenveld, PhD

“If the plan doesn’t work, change the plan but never the goal.”


Goran Verspui, PhD


Director of Process Research

The most rewarding part of my work is making plans for the scale-up of new molecules for clinical trials and discuss these with my colleagues and our clients. In Early Development there are many unknowns and plans often change. I love the dynamics in this field. Never a dull moment.

“The one constant factor in life is that things will always change.”
