Do research choices and unit upgrades carry over into Multiplayer?

I haven't dared touch multiplayer in StarCraft 2 yet but was wondering if the research points I'm spending and unit upgrades I choose in Campaign mode will carry over into my multiplayer games?

I don't know much about the game but want to pick what appeals the most rather than the de facto choices but thought this might hamper me when I get into MP. I'll need all the help I can get :)

No, since this would imbalance Terran vs the other two classes

The big advantage of splitting these two, is that they can do very cool stuff in the Campaign, while maintaining balance in multiplayer. This is a very big problem for World of Warcraft, where this has lead to numerous 'nerfs' of special abilities to maintain balance in Player vs Player.
