Environmental engineer and aerosol scientist with a Ph.D. in atmospheric ultrafine particle (PM0.1) research and over 10 years of experience characterizing aerosol properties, sources, and health impacts across environments in Southeast and South Asia, and currently the Arabian Peninsula. Proven track record leading field measurement campaigns with SMPS, OPC, CPC, LAS, and AQMS instrumentation, integrating ground-based and satellite (Sentinel-5P, MODIS) observations, and applying HYSPLIT trajectory analysis, statistical modelling, and machine learning to quantify aerosol-climate and aerosol-health relationships. Also has experince more than 8 years working with Sunset Carbon Analyzer (OC-EC) as well as experience with HPLC for PAHs analysis. Current research at KFUPM focuses on remote sensing for air quality in the arid region as well as the application of low-cost sensor for air quality monitoring both indoor and outdoor. Author of 45+ peer-reviewed publications (Scopus H-index 12), with demonstrated ability to design and lead multinational research projects, secure and manage SATREPS project deliverables, mentor graduate students, and translate scientific evidence into policy-relevant outputs for regulators and public institutions.
