Research in the lab of Emmanuel Chang centers around biological applications of mass spectrometry. Our major interest is in analysis and methods development for protein phosphorylation and other post-translational modifications. Applications include phosphorylation in cell cycle; ADP-ribosyltaion; mass spectrometry-based biosensors, and kinase inhibitors and enzyme kinetics. We also collaborate with other CUNY and external scientists who would like to harness the power of mass spectrometry to study there own interesting biological systems.

We supplement our experimental work with computational methods including bioinformatic protein sequence analysis and molecular modeling.

Dr. Chang's teaching interests include analytical chemistry, biochemistry, writing and data presentation, literature analysis, and innovations in introductory chemistry.
