Heather Brown joined PNNL’s Chemical and Biological Process Development Group as a research chemist, in December of 2005. Originally hired to maintain various analytical instruments, she now manages the Combinatorial High Throughput Laboratory. The combinatorial laboratory is a unique capability which allows for rapid screening of catalysts and reaction processes. Ms. Brown utilizes her chemical, analytical, and programming experience to coordinate work-flows for a wide variety of projects, primarily in the field of biomass utilization. Her and her team provide experimental design, execution, data processing, and reporting as part of the combinatorial service center. Ms. Brown handles all cost accounting and scheduling for the service center.
