The faculty of the PBI come from nine different academic departments. Each of these faculty members directs a laboratory which contains many of the specialized instruments that are required for his/her research program. In the present research environment it is often difficult for every lab to maintain all of the instrumentation and facilities required for any research program. The UC Davis research community has a strong tradition in cooperating in the sharing of research facilities and expertise. Each of the academic units housing PBI members maintains specialized facilities and instruments (photography equipment, computer rooms, controlled temperature rooms, etc.) to support the unit's research programs. In addition, UC Davis maintains many extra-departmental research facilities that are readily available to PBI researchers.
