We expect restaurants, casinos and other public places to be clean and relatively germ free. Vivek Raman, an environmental health specialist in Las Vegas, makes sure they are. He inspects public facilities to make sure they obey sanitation laws. He also monitors diseases in rodents.

Vivek was inspired to pursue a career in public health by his work in the Peace Corps, where he witnessed the hardships people face when they lack of basic health care. He hopes to return to the developing world, where he can use his experience to help impoverished people meet their basic health needs.
