A scientist studies or works in one of the sciences, typically through research and experiment to understand how the world works. An engineer applies that knowledge to design and build practical things such as machines, structures, or systems. In short, scientists focus on discovery and engineers on application, though the roles often overlap.

A scientist works specifically in one of the sciences, using research and experiment as their method. 'Researcher' is broader and covers anyone who investigates a subject systematically, including in the humanities or social sciences. All scientists do research, but not every researcher is a scientist.

The common noun 'scientist' is lowercase in ordinary writing, as in 'she is a scientist.' It is capitalized only when part of a formal job title or proper name directly before someone's name, such as 'Chief Scientist Jane Doe.' Otherwise the word stays lowercase.
