Robert M.W. Hofstra conducts interdisciplinary study in the fields of Mutation and Cancer through his research. He integrates Cancer and KRAS in his research. His research combines Biochemistry and KRAS. Robert M.W. Hofstra connects Biochemistry with Gene in his study. Borrowing concepts from Phenotype, Robert M.W. Hofstra weaves in ideas under Gene. His work often combines Phenotype and Mutation studies. Many of his studies on Laser beams apply to Laser beam quality as well. He integrates several fields in his works, including Laser beam quality and Beam divergence. His research on Beam (structure) often connects related areas such as Optics.
