Alexander Striebeck

I am an ambitious and reliable person focused on solving problems in a smart and efficient way using digital tools. In the past six years, I have acquired extensive knowledge of regulatory processes in the pharmaceuticl and food industry. This is supportedby my strong educational background in and passion for biochemistry and molecular biology.
