In 2012, he received his BFA in acting. Koch made his film debut as "Frank" in Eddie O'Keefe's independent short film The Ghosts. Koch works with music and images when acting. "When I'm working, I like to work with a lot of music. The more I can think of what a character would listen to, the more I feel like I have a place to create from". [Alexander agrees that he's using songs to give him insights into his character and not just to get him into an emotional space]. "I have a record player at home that I usually listen to, but since I've been in Wilmington [North Carolina, where the series is filming], I couldn't bring it with me. When I'm on set, I'm listening through headphones on my computer, just trying to zone in and focus. Britt [Robertson] always makes fun of me about how I'm always in my chair listening to music". He also works with images. "When I'm working, I find images and kind of attach to them. It just makes the dialogue so much stronger if you have a distinct image in your mind".
