Research/Clinical Interests:

My research is focused on developing biology-directed mass spectrometry strategies for protein biomarker discovery and verification. These strategies encompass peptide enrichment and fractionation techniques, mass spectrometry methodology, and bioinformatics tools. Proteomics technologies have potential to be of great value in molecular medicine, and in my research I am investigating changes in protein expression that occur in preeclampsia, cancer, and other disease processes. High quality, well annotated human biospecimens are critical for these proteomics projects and my research includes a program to investigate the pre-analytical variables that may affect biospecimen integrity. The assays developed through this work will be used to determine and define the effects of pre-analytical processing on banked biospecimens that are to be used for proteomic analyses.
