Not an expert in typography so I may be wrong, but I'd say it's a modern take on Humanist (also known as Venetian), one of the earliest Roman typeface styles. Here's a good article about this style: http://ilovetypography.com/2007/11/06/type-terminology-human.... I'm not sure if it can be classified as such though because it is built to work well on the screen and so has a lot of straight lines, closer to Transitional typefaces like Times New Roman, but even though the overall design is very modern, the feel of it seems to me closer to the Humanist typefaces. For example, the bar on the 'e' is sloping a tiny bit upwards, which is a distinctive characteristic of Humanist typefaces.
