Cross-functional collaboration and innovation with the goal to benefit patients.


Merck KGaA, Darmstadt, Germany is a multi-faceted company being comprised of three very distinct business units covering an unprecedented landscape of expertise connected by scientific curiosity. Leveraging the innovation potential at the intersection between disciplines offers a unique opportunity and competitive advantage. However, at times the sharing of knowledge within this interdisciplinary setting can be challenging. Therefore helping to connect scientists and enable this crucial exchange by fostering collaboration and critical discussion about new discoveries, innovative concepts and future trends is essential for bringing ideas from one field to another. I am striving to be part of this movement by actively connecting scientist from all units to develop novel products and create value. 

By working in the health care field whenever we advance projects, develop new molecules or technologies we as scientist are rewarded. This extends far beyond having made a new discovery and quenching ones curiosity. It is the knowledge that ones efforts directly impact patients lives. This is the greatest reward!

Cross-functional collaboration and innovation with the goal to benefit patients.
