Julian P. Whitelegge, PhD
Laboratory Director & Professor
Professor Whitelegge’s research and teaching are focused on the application of biological mass spectrometry to the study of structure/function relationships of integral membrane proteins, understanding protein misfolding and the relationship to neurodegenerative disease, elucidating radiation insult and mitigation biomarkers, exploring inter-relationships of metabolism and molecular mechanisms of diabetes, as well as other systems biology projects in peptidomics, lipidomics, and proteomics.
Gazmend Elezi, PhD
Associate Director
Postdoctoral Scholar
Dr. Elezi leads an interdisciplinary research program that applies mass spectrometry and multi-omics technologies to investigate molecular systems across biomedical, archaeological, and environmental domains. Utilizing state-of-the-art LC–MS and GC–MS methodologies, his research explores biological pathways and disease-related processes, ancient biomolecules preserved in archaeological materials, and environmental contaminants and their transformations. Through the integration of analytical chemistry with biomedical, archaeological, and environmental sciences, his work develops innovative approaches for understanding human health, past societies, and human–environment interactions across time.
Michele Spinelli
Visiting Graduate Researcher
Michele is a Visiting Graduate Researcher from the University of Naples, Italy, and a PhD candidate in Medical Sciences with over eight years of expertise in high-resolution mass spectrometry and analytical chemistry. Currently completing his research residency at the Pasarow Mass Spectrometry Laboratory, he is focusing on advanced proteomics to elucidate the molecular drivers of Chronic Kidney Disease (CKD). By integrating a strong background in metabolomics with sophisticated LC- MS/MS workflows, Michele aims to identify novel biomarkers and bridge the gap between complex instrumental analysis and clinical nephrology.
