There are many opportunities for undergraduates to work in the department. In addition to working as consultants, working for the UTA program, and working with the technical staff, there are also opportunities for undergraduates to assist with or conduct their own research.
Note that most of these positions are hired regularly, but some become available on a less predictable basis. Check the individual pages, which should provide information about hiring and which faculty or staff person you should contact.
Undergraduates can be paid or receive academic credit for research work. See the page on undergraduate research opportunities.
