Using AI to power real-world learning in physiology

AI is not treated as a novelty or a shortcut. Instead, Deparatment of Physiology instructors integrate it deliberately to support applied learning, strengthen clinical reasoning and require students to evaluate information critically. Together, these approaches reflect the department’s ongoing effort to prepare students for the demands of modern science and medicine.
