Have you dabbled with Julia [1] before? It sounds like it might be right up your alley. It's not a lisp, but it's very "lispy" in a lot of ways, and it's focused on scientific/numeric computing with an active community focused on the same. The creators also mentioned J as an influence I believe, though I haven't used J myself, so I can't comment on that.
