I don't know what "abstract interpretation" is, can't help you with that. If you are interested in the real life implementation of theoretical PLT concepts, I'm not sure if this might help, but there is this page: https://www.ponylang.io/blog/2017/05/an-early-history-of-pon... where the designer of the Pony Language tells the history of how he did a Ph.D. on sound stuff and then went to design Pony. You can probably start hunting papers from this trail. Personally, I'm nostalgic of the Wirthian languages, and started developing a PL/0 compiler with an LLVM backend, before some day, if hopefully I ever develop all the needed skills, put all the Wirthian languages in a cocktail shaker, add a dash of new PL concepts, and see how that tastes.
