frontier research

[SUDOnym]

frontier research in physics today is in cosmology (dark matter, dark energy big bang.), particle physics (LHC), string theory.

Would everyone agree with that? or am I leaving something out?

What do you mean by frontier research? I would argue that all research is frontier in the sense that it pushes the boundaries of our knowledge. You could however break research down into discovery and applied; the former being when we address questions such as "What is the cause of X?" the latter being when we address questions such as "Can we build X that is capable of doing Y?"

I am thinking more about "discovery" research...

In that case pick pretty much any field of physics.
