Liz Holm, a materials science and engineering professor at Carnegie Melon, saw the increased demand first-hand in May, when one of her graduating PhD students, who used machine learning methods for her research, was overwhelmed with job offers, none of which were in materials science and all of them AI-related. Eventually the student took a job with Proctor & Gamble, where she uses AI to figure out where to put items on store shelves around the globe. "Companies are really hungry for these folks right now," Holm said.
