Our lab requires personal initiative, active involvement, and a genuine interest in all phases of research (planning, preparing, executing, analyzing, writing, presenting). We usually have a small number of heavily-involved lab members. We select assistants who will move things forward without being pushed; who won't just wait for further instruction but will ask questions and make suggestions and offer potential strategies and solutions.

The primary focus is for students to learn new knowledge and skills and gain research experience, in order to supplement their classroom education. But we also want to produce significant output in terms of disseminating our research findings (conference presentations, publications). This will happen if the student lab members are actively involved and share the goal of being a productive lab.

We have semi-regular (weekly/bi-weekly) all-lab meetings either in-person on campus or through web conferencing (Zoom), and communicate regularly through a group e-mail address. Subgroups working on specific projects also communicate regularly among themselves. We have a central lab office in Amador Hall, Room 203, that can be used for small meetings, data scanning/ cleaning/ analysis, and for storing research materials.

If this sounds like a lab experience you want, and that you can make a substantial contribution to, please download and complete the Research Assistant Application/Survey and submit it to Dr. Hurtz at While we may not have immediate openings or needs, we will note your interests and skills in case of future needs for new lab members.
