Gel electrophoresis is used in forensics, molecular biology, genetics, microbiology and biochemistry. It incorporates concepts from fields such as chemistry, physics, physiology, microbiology, biochemistry. It can be used in hospitals and microbiology/molecular biology research laboratories. Virology is a subfield of microbiology. Undergraduate programs are offered in Biomedical Sciences, Environmental Health, Microbiology, and Neuroscience. Later he joined the faculty at Rutgers University in the Department of Biochemistry and Microbiology. The study of viruses is known as virology, a subspeciality of microbiology. Microbial genetics is a subject area within microbiology and genetic engineering. The study of bacteria is known as bacteriology, a branch of microbiology. Bhabha also encouraged research in electronics, space science, radio astronomy and microbiology. One noteworthy aspect of the work is his anticipation of microbiology and epidemiology. This is especially true for samples for lab testing in cytology or microbiology. Blenders also have a variety of applications in microbiology and food science. Culture is technically difficult and not routinely available in most microbiology laboratories. Robert Koch, a pioneer in medical microbiology, worked on cholera, anthrax and tuberculosis.
