Biochemical engineering integrates biological system expertise with engineering fundamentals to enable large-scale production of high-value items including medications, food products, antibodies, and enzymes. This specialization equips students with a quantitative, process-oriented grasp of biological systems, grounded in chemical engineering fundamentals like thermodynamics, reaction kinetics, and transport processes. The curriculum explores subjects such as mass transfer-influenced enzyme reactions, bioreactor engineering, genetic modification techniques, mammalian cell cultivation, and bioproduct recovery. Purdue's Chemical Engineering Department is actively investigating optimal methods to transform feedstocks like cellulose, simple sugars, or carbon dioxide into valuable biological products through diverse conversion pathways. A key responsibility for biochemical engineers involves developing and optimizing systems for both manufacturing and isolating biological compounds. Professional opportunities predominantly exist within the biomedical, pharmaceutical, and food production sectors.
