  • Dr. Alan Doucette, PhD


Professor, Department of Chemistry


Dalhousie University, Faculty of Science

Research Interests:

Proteome analysis, biomarker profiling, technology development and assessment (separations and mass spectrometry)

Dr. Doucette aims to translate proteome profiling into routine clinical practice. The promise of proteomics as a tool for biomarker discovery or disease profiling has, to date, gone largely unrealized. This is due to an inherent variability in the standard approaches used to assess complex protein mixtures. His fundamental research in the Department of Chemistry challenges the standard practices involved in proteome analysis. Through his systematic efforts, Dr. Doucette is reinventing the conventional proteomics workflow, providing novel technologies to make proteomics more routine, efficient, and reliable. These strategies are applied in collaboration with others to clinically relevant samples.

Membership Status:

Dr. Doucette is a BHCRI Associate Member.
