Arsalan S. Haqqani received his PhD in Biochemistry from the University of Ottawa in 2003 under the supervision of Dr. H. Chaim Birnboim. He then joined the National Research Council of Canada (NRC) in Ottawa, where he completed his post-doctoral research and held various research positions. He is currently a Senior Research Officer in the Human Health Therapeutics Research Centre at the NRC, where he leverages advanced mass spectrometry techniques for the development of therapeutics and biomarker quantification aimed at treating CNS diseases, inflammation, and other disorders. Dr. Haqqani’s utilizes mass spectrometry to address the following areas of interest: brain delivery and bio-distribution (PK/PD) of therapeutics capable of crossing the blood-brain barrier (BBB); identifying and validating biomarkers in clinical samples from various brain disorders (e.g., Huntington’s disease, Alzheimer’s disease, Parkinson’s disease, Traumatic brain injury, Multiple sclerosis); understanding intracellular trafficking of antibodies through the BBB; extracellular vesicles (e.g., exosomes) as clinical biomarkers and potential therapeutics; brain and other tissue specific targets; identifying and characterizing post-translational modifications (e.g., glycosylation) in biological samples.
