on a bike can you change from campagnalo shifters to shimano shifters?

i am looking to buy a new road bike, but the bike i am looking at has "campy" shifters. im used to shimano shifters. i know its possible to change the shifters, but would it work?

also, if you want to, please tell me the name of a bianchi bike, that is not all carbon fiber and uses shimano
