Idris is an experimental language exploring the practical benefits of dependent types, and providing a modular backend for code generation (e.g. it can emit either C or Javascript currently).
I wouldn't say that Haskell is somehow better at being translated to assembly than, say, C. The real power is in the ability for the language to express the author's intent, and for that intent to be reflected in the resultant machine instructions. It's something that's surprisingly difficult to do, and part of why there are so many languages with different syntax and semantics [2].
One way to try and guarantee that the author's intent is translated accurately is to try and add constraints in the form of a strong type system (e.g. Haskell). I think this is a rather neat idea, and at the very least worthy of some time skimming through papers or listening to talks.
As software gets more and more complex, more people are finding that these ideas are useful in non-academic settings. I think my favorite example is Galois' SMACCMpilot project, which seeks to write secure, verified autopilot code in a Haskell DSL [3].

You miss out on lots of $.
Chasing the next popular bit of research 10 years in advance is a bit of a fool's errand, so the best you can do is follow along with fields that you think are personally interesting.
For a more serious answer, I do think that FPGAs are going to become much more applicable to general-purpose-computing soon. Most of the tooling and language support around them is pretty archaic, and tools like CλaSH [1] make development much more friendly.
The Glasgow Haskell Compiler is also ostensibly a long-lived, continuously updating research project. Simon Peyton Jones summarized the State of GHC recently [3].
