Term paper topics

Below are topics for term paper (report + presentation). Students will need to pick one topic (latest by February 15, 2021) and make a report and then give a presentation (at the end of the semester). The sample suggested literature for each of them are given below. Once students pick one topic, they are encouraged to explore more literature.
