Research Support Assistant | Proteomics Resource Center in New York, NY

Organization Overview

The Proteomics Resource Center at The Rockefeller University masters most aspects of mass spectrometry based proteomics which includes denovo sequencing, targeted studies, quantitative proteomics profiling based on label-free quantitation as well as metabolic labelled samples (SILAC), chemical labeling, tandem-mass tag technology, absolute quantitation, and global post-translational analysis. The Center also offers LC-MS based analysis of small molecules, polar metabolites, and lipids. Very importantly, the Center is a source for help with planning of mass spectrometry-based experiments, and the Center have the capability to offer in-depth collaborative analysis. Also, the PRC is operated in a boutique style, encouraging the scientists of the Center to work closely with users to create a tailored approach to fit the many unique questions that can be answered by analytical mass spectrometry. The PRC is equipped with Orbitrap-type mass spectrometers (high resolution/high mass accuracy), operates a triple quadrupole, and can separate analytes using both nano and high-flow liquid chromatography. The Center is equipped with multiple high-performance servers for data analysis. In addition to analysis by mass spectrometry, the Center offers production of custom peptides and peptide libraries and different pre-mass spectrometry fractionation techniques, which include off-line separation of peptides and proteins by liquid chromatography.


Reporting to the Metabolomics Platform Manager, the Research Support Assistant will focus on the Metabolomics Platform at the Proteomics Resource Center (PRC).
