In the online version of this article (paragraph 4), Chad Walton is incorrectly said to have graduated from a dual-degree program. The text should read, “...Chad Walton, who received a master of biomedical technology (MBT) from the University of Calgary....” The program with the eight students he is referring to is the MBT program, not the dual-degree program. The MBT program does, however, have a business component. The error has been corrected in the HTML version of the article.
