It was 3 AM when I finally made an iron ball levitate under an electromagnet. For the two weeks preceding that moment, I built, calibrated, and debugged the op amp circuitry for a feedback control compensator to keep a ball at a predetermined height. That was an assignment in the graduate mechatronics course at Columbia. The course introduced me to the field of mechatronics, the area I want to focus on for my engineering career. The mechatronics course was my favorite course at Columbia because it advanced me towards the kind of engineer I want to be. I aspire to become a mechatronics researcher involved in the design, development, and dissemination of medical devices to improve healthcare outcomes for patients. I would not have found that calling without Columbia Engineering.
