As medical fields become more immersed in data, mathematics can provide more insight in the study of medicine. Helen Moore is a mathematician who has worked for medical companies. Originally, Helen’s interest did not lie in the medical field, but after attending some conferences and workshops related to mathematics and medicine, she became interested. Later, she was offered a job with Pharsight (a pharmaceutical company) as a senior scientist. When a pharmaceutical company develops a new drug, they must determine safe and effective dosages to prescribe to patients. Helen used control theory and mathematical modeling to do this. Michael Cannon has a B.S. in mathematics and a Ph.D. in epidemiology and works for the Center for Disease Control and Prevention doing research on the prevention of birth defects.
