Andrea Zudrell

The vivid explorer

With a big appetite for exploring the world and a bag full of ideas, Andrea set off and left her home in Western Austria to see places. She first moved to London and savored the city life, then travelled to South East Asia and Africa.

After returning to Vienna, she studied veterinary medicine and followed, hence following love for books and her strong interest in all kind of animals – the big and very small ones. Yet she’s very fond of a particular one – her dog Kathi.

Both Kathi and her darling best-daughter-ever keep her on her toes with their vivacity and jollyness.

A passionate character, Andrea now follows her new passion at DREHM Pharma: Medical Writing and Pharmacovigilance.

Eva Bauer

The Eagle-Eye


Whenever possible, Eva is out in the open air – you can meet her on the back of her Icelandic horse, hiking hills and woods in Austria and abroad – or while fancying archery.
Whatever she does, she always carries her camera with her, as photography is one of her big passions – and she needs her keen eye for both photograpy and archery.
On a rainy day, she enjoys doing her regular Yoga-workout or spinning around some Salsa moves.

A little whirlwind, Eva started early to discover the mysteries of nature, which resulted in her joining the world of science:
Eva studied biomedicine and biotechnology and spent some time in Leipzig where she took part in a visiting research fellowship.
Back home, she finished her PhD-studies and discovered the joy of writing.

In 2016, Eva joined the DREHM Pharma Medical Writing-Team and shares her photographic skills whenever necessary.

Johanna Klocker

the ChocolateYogi

Always riding on the crest of a wave, Johanna swam her way happily through childhood and many swimming competitions. Later at university, she transitioned from nutrition science into the pharmaceutical world.

To keep her spirits and energy high, she always makes sure that her favorite treat and energy booster, chocolate, is within easy reach. At DREHM Pharma, her fully stocked chocolate drawer is well known (and often visited) by all! As a student, Johanna used to swim laps around Lake Constance (Bodensee) to compensate for the extra calories, but after moving to Vienna, Johanna found a new solution: Yoga! She greets every morning with sun salutations and every evening with meditative repose.

In this way, Johanna stays both spiritually and physically in shape while pushing her career ever forward.
Currently she expertly juggles several different hats in our office (including Regulatory Affairs, Market Access, and as Head of Quality Management and Product Development/Production with calm nerves, a cool head and the sweetness of chocolate.

Karin König

The creative Herbalist


For as long as she can remember, Karin has always felt at home in the garden. Her love of plants goes back to her first experiments cultivating vegetables and herbs, as well as making her own organic products such as lip balm.

Currently she grows about 50 different herbs, including some unique and rare items. In addition to her botanical passions, Karin is also pationate about handicraft and various types of needlework. She loves to work with natural fibers and to dye natural materials with various herbs.

With a degree in Food Science and Biotechnology, Karin enjoys working in the field of Regulatory Affairs.

Meanwhile she decided to go back to her „roots“ and devote herself to the study of applied plant sciences. This focused study helps Karin gain a much deeper understanding about the work that she is already doing and helps to open even more opportunities for the future. She loves finding connections, especially in herbal medicines, between her work at DREHM Pharma and her study at the university.

Mario Koller

Mr Ants-In-His-Pants

„We Can Do It!“ – this is what describes Mario in a perfect way.
Being producer and screenwriter of „Blockbuster – life is a movie“ – Austria’s first self-financed fund-raising motion picture, dedicated to support St. Anna’s Children’s Cancer Research Institute – just in his spare time? No problem!

In addition, Mario is lecturer at Danube University Krems.
