My work is a 
story of sustenance.


Making milk safe for babies.

Niusheng | Application Engineer

I help keep babies safe. I develop applications for our mass spectrometer, a powerful device that has many uses, including ensuring powdered milk is free from a potentially deadly chemical. Since our customer monitors more than 750,000 tons of infant formula each year, that’s a huge responsibility. In addition to identifying this particular chemical, my work helps the same customer detect over 500 pesticides across a wide range of products.

My job encourages innovation and new thinking. I get to apply my knowledge and our technology to real-life problems, and it’s rewarding to see that what I do today can keep the next generation safe for tomorrow.

When you’re looking for an opportunity to nourish your own professional future, you’ll discover that, at Thermo Fisher Scientific, each one of our extraordinary minds has a unique story to tell.
