I reached out to several of the professors that were listed under my program as well as others who were teaching courses that I thought I might be interested in. Almost all of them responded but mostly refereed me to the admissions Dept for admissions/applications questions. Thus if u want to engage a professor in a more in-depth dialogue maybe asking about the field of study they are connected to, and that u are interested in, might be a good way to go. One of the professors and I actually had a video chat. It was a great experience. She ended up talking to me about the school culture as well as my admissions process.
