PNNL

Dr. Paul Piehowski is an analytical chemist in PNNL’s Environmental and Molecular Sciences Division, supporting the Environmental Molecular Sciences Laboratory (EMSL) user program. Piehowski is an analytical chemist whose research is focused on the application of mass spectrometry to biological problems. Since 2009, he has been working with the Integrative Omics group at PNNL to improve reproducibility, sensitivity, and throughput of proteomics measurements. These efforts have resulted in novel capabilities made available to the EMSL user community that have enabled new areas of research in high-throughput proteomics and nanoscale proteomics measurements.  

The high-throughput sample processing pipelines have been applied to support large-scale, clinical proteomics efforts at PNNL, such as the Environmental Determinants of Diabetes in the Young, Proteogenomic Translational Research Center, and Molecular Transducers of Physical Activity Consortium. Most recently, he has adapted this platform to study breath samples from COVID-19 patients to develop signatures of severe COVID infection. During his tenure, he has served in varied roles in this effort from laboratory scientist to principal investigator.  

Improvements in measurement sensitivity have culminated in the development of the nanoPOTS (Nanodroplet Processing in One pot for Trace Samples) platform that can make broad proteomics measurements down to the single cell level. This sensitivity, combined with PNNL’s custom automated sample analysis, allows the creation of proteome maps with spatial resolution of better than 50 µm. 

The development and application of these methodologies have led to many publications in high impact Nature family and Cell journals. The nanoPOTS platform was a finalist for an R&D 100 Award. His developments have been recognized internally with numerous outstanding performance awards and an exceptional contribution award. 

Piehowski received his PhD from Penn State University, carrying out his thesis research developing and applying mass spectrometry imaging techniques for single cell analysis. His research was supported by the Chemistry Department Braucher fellowship.
