Mark is entering his final!!! year in graduate school. He has worked on spatial memory, and now works on long term object recognition. No matter what he tells you, you should know that the project is going really well and he is doing great. Seriously, don't worry if he seems anxious.
Feitong's interests include running control experiments. His hair is now much shorter than it was in this picture. But if you store this picture in your working memory, it will lead you to perceive him as having longer hair in person, at least that's what his research suggests.
