Faculty Profile

Cristina C. Clement, Ph.D.

Dr. Cristina C. Clement

Research Assistant Professor, Department of Pathology

 

Professional Interests

Research conducted in the lab of Dr. Laura Santambrogio in the Pathology Department/AECOM.

1. Mass spectrometry of proteins and peptides from different biological fluids (lymph, plasma, synovial fluid), biomarkers discovery;  label and label free quantitative proteomics aproaches for monitoring redox changes in the proteomes during aging and autoimmune diseases/cancer. 

2. Enzyme based peptidomics coupled with nanoLC/MS/MS for discovery of neoepitopes derived from the processing of extracellular proteins (mainly collagen I and II (human)) by metalloproteases, cathepsins and other proteases.

3. PTM (posttranslational modification) scanning and Redox proteomics (PTM of oxidative stress) assays for profiling of peptides/proteins in dendritic and other immune cells in aging, autoimmune diseases and immuno-compromised pathological states.

4. Biophysical methods for study the proteins folding/unfolding under oxidative stress (oxygen free radical modified proteins): circular dichroism for secondary structural changes during oxidation of collagens, fluorescence studies of the tertiary structures changes during proteins unfolding under pathological conditions (such as reactive oxygen species generated during oxidative stress in aging).
