About me
My name is Charles Spence and I lead Discera. After many years working in the life-science recruitment world, I decided to work for myself. Before doing recruitment I graduated with a biomedical degree, have worked in hospitals (including translation work in Seoul, South Korea), and also spent a year working in diabetes research in Stockholm. After doing research and travel, a career in business and science felt the most appropriate.
In 2023, I decided to launch my firm - Discera Search. A firm committed to solving the biggest talent needs of early clinical stage SME biotechs on the East Coast and DACH.
