What is bioinformatics? The term refers to information processes in living systems. Bioinformatics experts research these processes and build computer models of the structures so as help understand them. This facilitates the creation of new medical knowledge, for example, for the production of new pharmaceuticals, or a deeper understanding of DNA.
To follow this career path, you need to take a bioinformatics degree, which usually comprises biology, computer science and chemistry.
