Ramses Martinez never bothers turning on a TV when he checks into a hotel. The room's safe is a much more entertaining option.

Martinez loves puzzles, and he considers lock-picking one of the ultimate tests.

The professor who holds a joint appointment in industrial engineering and biomedical engineering gave Purdue chemical engineering student Yasar Dambo the lowdown on his hobbies, including different kind of “enhancements” (hacking) Martinez does in his spare time, and much more in the latest "Office Hours."

"Office Hours" offers a look into the lives of Purdue Engineering faculty, focusing on how they spend time away from the University's West Lafayette campus, what motivates them in life and much more.  

The videos publish once per month during the academic year and feature professors from across the College. The full playlist can be viewed on the College of Engineering's YouTube channel.
