Professor Bradford is a stand-out teacher. He is very knowledgeable, enthusiastic, sometimes entertaining and funny and always a lively and high energy lecturer. He is organized, has very good PowerPoint slides (downloadable via Courseworks). Columbiaâ€™s tuition is not cheap but if any class Iâ€™ve taken here (in the SUMA program) seems worth the price, it was this one with Bradford. If he taught other classes that interested me then I would very seriously consider themâ€¦ Very highly recommended!
