Health sciences PhD candidate Hyunjin Kim has accomplished award-winning stem cell research in the lab of Professor Aaron Bowman.Tim Brouk Written by: Tim Brouk, tbrouk@purdue.edu Hyunjin Kim discovered his career calling after taking an immunology course as an undergraduate at Hanyang University in South Korea. The only problem: He discovered his passion for human health one semester before he was to graduate with an international studies degree. By adding a last-minute major of bioengineering with his almost-completed international studies requirements, it raised eyebrows in his advisors office as well as back home in Seoul. My parents were not too happy about it, Kim admitted with a laugh. Kim as well as his mother and father can smile now as that last-minute decision set his career course more than 6,600 miles away to West Lafayette, where he would find a passion in stem cell research in the Purdue University College of Health and Human Sciences.
