<p>I think you may be on the right track, looking at IDS, though it does have some odd prerequisites that only marginally relate to your fields of interest. I don’t have any specific recommendations, but wanted to note the following regarding Area of Concentration requirements: “A minimum of 20 UNITS (at least SIX courses) drawn from at least THREE fields or disciplines. Courses for this requirement must be UPPER DIVISION, i.e., numbered 100 or above.” It can include classes from other schools.</p>

<p>Good luck!</p>
