Your context...

We have the following roles: Professor, Asst. Professor, PhD Student, Masters Student, Undergraduate Student, Visiting Student, Engineer and Postdoc. You can also add a new role if it makes sense (roles in file team/index.LANG.html).

Add a picture, add it to the assets directory with around 300x300 pixels as a JPEG image. The height and width of the image should be equal, so it is a square.

Once someone leaves the group, change alumni to true and add alumni_since: XXXX to make them as alumni.

Please send a pull request with the changes and an admin will merge it.
