About us


EV Biotech was founded in July 2018 by Linda Dijkshoorn, Agnieszka Wegrzyn and Sergey Lunev, and has been operational since January 2019. The company is located in Groningen, North of the Netherlands, surrounded by many chemical industrial companies in the North.

The mission of the company is to evolve the chemical feedstock market by shifting it from petrochemical-based to bio-based chemical production, using Microbial Cell Factories.

The Uniqueness of EV Biotech lies in the synergy between our computational algorithms and our strain development, and therefore within the synergy between our different teams. Our dry lab team translates all potential wet-lab experiments to in silico experiments, and automates them. Our wet lab team communicates directly with the dry lab team creating the best experimental designs for both wet and dry lab. With smart planning, direct and good communication the EV Biotech team can create results fast and accurately.


The EV Biotech team is fast-growing and always looking for new employees. We offer an exciting, professional work environment with a lot of growth opportunities.

“I have always been fascinated with biology, chemistry and engineering.”

As a little girl I dreamt of becoming an inventor, entrepreneur and scientist. EV Biotech is the realisation of that dream combined with my passion for the creation of a sustainable society. I believe that with the current technologies we are able to achieve a sustainable society now, but that takes revolutionary steps in many very conservative markets. I strive that EV Biotech will become such a revolutionising force.

Nature has offered us some of the most potent drugs, strongest materials, and most delicious flavours and fragrances. Its beautifully complex structures are incredibly challenging to synthesise chemically, resulting in vast amounts of chemical waste. By letting nature do the job itself, EV Biotech creates a green alternative for the large-scale production of those compounds that we need and desire in our lives, without harming our environment. I strongly believe in EV Biotech’s mission and have proudly joined team EV to contribute to a greener future for our society.

“It’s still magic even if you know how it’s done.” Terry Pratchett

In my vision, our future generations will exist on this planet in symbiosis with nature. I believe that for this purpose, we must create a sustainable economy that uses the huge potential of nature instead of exploiting it. By taking advantage of the tools nature gives us, we can create green alternatives for large-scale production of compounds that we need and desire in our lives.
One of my biggest interests lies in solving riddles and and understanding complex systems. I have always been fascinated by the complexity of the nature surrounding us and feel the need to to preserve and protect it with the desire of making the world a better place.
My current position at EV Biotech allows me to combine my interests and passions. I believe that I can use my skills and knowledge to contribute to a greener and more sustainable society.

The main focus of my PhD research was on understanding the protein environment on the excited-state processes in small biomolecules (chromophore).

I am hugely fascinated by the role of protein environment in facilitating biological functions! Specifically interested in rationalizing the jiggling and wiggling of biomolecules through molecular dynamics simulations.  EV Biotech helped me in realizing the potential of theoretical simulations in addressing the industrial needs. If your passion can be your job then I guess there is no stopping!

At EV Biotech, my work largely focussed on setting up simulations, better prediction of protein 3D structure, developing pipelines for molecular understanding of the bimolecular processes, and possibly develop computational tools for efficient atomistic simulation.

Since I was young, I’ve always been fascinated by innovations. When I learned what the possibilities of genetically engineered bacteria are, it totally got me hooked. A bacterium can be made into a small factory capable of producing almost anything what is desired. After starting my bachelor study my interest only grew larger, especially in subjects like genetic engineering of micro-organisms and molecular biology. My internship at EV Biotech gives me the opportunity to work on a project based on my interests. The team consist of people with different expertises, which contributes to solving problems. The daily meetings give insight in what everybody is working on, what also helps in meeting your own goals. This internship at EV Biotech gives me the opportunity to develop my knowledge and laboratory skills.

“Every process in life can be described as building blocks with inputs and outputs. It’s up to us to choose which building blocks to use to build a better future.”

Ever since I was little I wanted to become an inventor or scientist. When I was first exposed to biology and saw the most sophisticated processes that are found in the tiniest of organisms, I fell in love. I knew that there was more to learn from nature to provide better solutions for problems humanity faces today. If we work together with nature, a bright future lies ahead. EV allows me to make a difference in the world by providing better alternatives by leveraging the power of nature.

“It’s not enough that you believe what you see. You must also understand what you see.” /Leonardo da Vinci/


Biology was one of my least favourite subjects but studies on chemistry and physics during the final gymnasium years intrigued me to apply for bioengineering studies as an alternative to applied chemistry. During my years as an undergraduate, I enjoyed working with downstream processing methods that spanned from a single strain engineering approach. The follow-up studies based on systems biology led me to the computational tools that allow strategizing microbial strain design development. I feel blessed to work at EV Biotech due to the ability to exploit my modelling skills and witness my actual impact on the strain design process. We are a young organization led by an enthusiastic group of specialists of very similar age and feel eager to demonstrate our competencies to introduce more sustainable solutions for the greener future. As a metabolic modeller, I identify the parts of metabolism that shall be enhanced to achieve a higher efficacy and believe that our developed microbial cell factories will introduce new pathways in the bio-based industry.

I joined EV Biotech on a 1-year European Commission SME Innovation Associate grant as a molecular dynamics expert, because their approach for changing the way to produce new materials from greener sources are very interesting and novel. We need to change the way we are producing materials, avoiding contamination and being more effective in the final disposal of those.

My main interests focus on biological processes simulations, development of pipeline, scripts and software for computational chemistry and bioinformatics.

During my bachelors, I got captivated by how we can use microorganisms in industrial settings to produce all kinds of chemicals and build a bio-based economy. I’m very curious on how process conditions influence cells and their production capabilities. This is the most exciting puzzle in biotechnology to me. At EV Biotech I will help to solve pieces of this puzzle by investigating the impact of (scale-up) conditions on our strains using experimental data and modelling and see how we can improve yields and make them more robust.
