Heather Job joined PNNL's Chemical and Biological Process Development Group as a research chemist, in December of 2005. She began her career in the analytical department, maintaining, operating, and developing the group's capabilities in routine sample analysis. With her organizational skills, attention to detail, and computer/programming expertise, Mrs. Job quickly transitioned into the combinatorial department. She currently manages the High Throughput Center (HTC) and overseas operations in the Analytical Department.

The HTC is a unique capability which allows for rapid screening of catalysts and reaction processes. The center consists of a suite of automated instruments, controlled and monitored by a central database, and designed to test catalysts on a milligram scale. Enhanced robotic catalyst preparation instruments allow for a wide range of preparation techniques. Mrs. Job utilizes her chemical, analytical, and experimental design expertise to coordinate work-flows for a wide variety of projects, primarily in the field of biomass utilization. Her and her team provide experimental design, experimental execution, data processing, and reporting as part of the HTC Service Center. Mrs. Job handles all cost accounting and scheduling, as well as day to day operations for the center.
