The 25-year old has signed a three-year deal with the Tigers, joining for a fee of £2.6million, and is excited about starting with his new club after being the joint top scorer in 2.Bundesliga last term.
"I'm delighted to have completed my move to the club," he told the Hull's official website.
"I think I have joined a great group of lads. Everyone is friendly, everyone is nice and, most importantly, everyone likes to work and train hard which is exactly what I like to do.
"I had a great time at my previous club but that is in the past and the only thing I'm focused on now is my future with Hull City.
"Playing in the Premier League is a big goal for me and I believe Hull City can help me achieve that goal.
"I believe the Premier League and the German Bundesliga are the biggest leagues in world football and, if I can play in the top-flight of English football, it would be a dream come true for me."
