I'm applying to schools as a second bachelor's degree candidate for computer science this fall. Post-bac admission is often very competitive, and one school has posted, "it will be important to work with the department and Admissions on your applications." Admissions advisors I have spoken to have suggested that having a professor on my side will be the best/only way to gain admittance (my grades in pre-requisite math, physics, and intro cs courses are good; this is a reaction to their minimal interest in post-bacs). There are a few professors at this school whose work I am very excited about, and would love to talk to. However, my previous degree was in a totally different field (humanities), so I'm starting from the beginning. How can I best reach out to these people so I come off as a promising candidate as opposed to yet another desperate applicant?
