I might as well fess-up seeing how everyone else is...
I'm a research physicist working at a US national lab, Jefferson Lab. We do fundamental research in nuclear and particle physics (no connection with nuclear weapons or energy, just the basics of interactions of particles and nucleii).
I've been in it since finishing classes in grad school in 1977 and moving on to straight research in particle physics. I worked at particle physics labs for many years until moving to Jefferson Lab, which does research at the boundary between particle and nuclear physics.
Note: my field, particle physics, gave the world the World Wide Web! It started as a project in major European particle physics lab, CERN, and its purpose was to simplify distribution of information to particle physicists around the world. The founder of the web, Tim Burners-Lee, was a computer scientist working at CERN. No one, of course, had any idea it would take off and transform the world.
