My Story…  

My career began in Telecommunications, where I worked over 12 years as an electrical engineer. It was challenging and fast paced but when a role at Thermo Fisher opened up, I saw an opportunity to do motivating work that has a bolder meaning for society. I joined Thermo Fisher just over a year ago, helping to design life science instruments for researchers as part of the Genetic Sciences R&D team. I’m able to apply the same knowledge and expertise as an electrical engineer but for the purpose of mission-driven, life-saving work.  – Jessica, R&D Manager
