<p>Email them tomorrow and pose the question. From the physics department:
"If you are interested in the undergraduate or graduate program and you will be at MIT or in the Boston area, please visit the Department of Physics, Academic Programs in 4-315. A staff member can provide information about the undergraduate or graduate program and refer you to appropriate areas of interest including faculty offices and/or labs.</p>
<p>The volume of requests and the wide range of faculty interests precludes a centralized process for arranging faculty appointments. However, potential students are encouraged to contact research labs and/or individual faculty directly to inquire about availability during your visit."</p>
