Yeah.
First, when starting a new game, you can change "game speed" on the "map settings" screen. Use "Epic" or "Marathon" to slow things down. Epic increases research costs by 50%, while marathon increases research costs by 100% (so, they're doubled) but also production costs and influence costs by 50% both.
Modding wise, make a directory called "Slower Research" or something like that in the Stars in Shadow\Mods. In it, create a subdirectory called "@Technology" (yes, starting with an "at" symbol). Then copy the file "~TECHNOLOGY.lua" (yes, starting with a tilde) from Stars in Shadow\Lua state\@Technology to Stars in Shadow\Mods\Slower Research\@Technology. Edit that copied file. Scroll down just a little bit and you'll see:

_G.tech_costs = {..early,..mid,..late}
Those are the values that are attributed to techs, e.g. "guidance systems" is "early(.1)" which means it costs 80, "fusion warheads" is "mid(.2)" which means it costs 600 by default, while "planet construction" is "late(.9)" so it costs 30000.
