He delivers clear and informative lectures, though a bit math-heavy. He clearly cares about students learning and is very accessible outside of class/online to help. Homeworks are long but fair. Exams can be intimidating (sometimes the problem only has a few words), but he grades leniently.","source_url":"https://www.ratemyprofessors.com/professor/2517429","quality_rating":4.0,"difficulty_rating":4.0}]
