Leonard Hofstadter is just about as close to Sheldon and Amy Farrah Fowler. However Amy Farrah Fowler was a neuroscientist with a PHD in neurobiology with a research focus on addiction in primates and invertebrates, occasionally mentioning such experiments as getting a capuchin monkey addicted to cigarettes or starfish addicted to cocaine. Leonard was an experimantal physicist. Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as the Cavendish experiment, to more complicated ones, such as the Large Hadron Collider. Neither of which we understand.
