Our Research Staff keep our labs and programs running and ensure the quality of research results. Many also train students in the lab and field as well as engage in public outreach and tours. They represent a source of knowledge, talent, and experience that's critical to INSTAAR’s mission. Current staff with questions or concerns should contact Chad Wolak (Staff Representative). Prospective staff should check the Jobs page and consider contacting individual INSTAAR Faculty: FellowsResearch Scientists, and Fellows Emeriti.
