Ph.D. Chemistry, University of Puerto Rico, 2011

Professional Experience and Research

Dr. Delgado is currently serving as the Director of the Center for Atmospheric Sciences, the Principal Investigator (PI) in the Hampton University (HU) Lidar Laboratory, campus PI in the NOAA Center for Earth Science Systems for Remote Sensing Technology, Team Leader in a NASA’s Increasing Participation for Minority Serving Institution program and the Unified Ceilometer Network (UCN). In addition, he has served as PI in multiple proposals and field campaigns in air quality and wind energy, and federally sponsored academic and research consortiums that promote diversity, equity, inclusion, and accessibility for underrepresented minority communities.

His research relies in the integration of in-situ ground meteorology and chemical composition measurements that are combined with profiling remote sensing technology and satellite products to study the coupling of chemistry and dynamics in the fields of air quality, wind energy and meteorology. The remote sensing portfolio and expertise includes multiple lidar technology (elastic aerosol, Raman (water vapor) and scanning Doppler wind lidar (wind direction and speed, and vertical velocity profiles), radio sondes and microwave radiometer. Dr. Delgado has conducted extensive assessment of multiple algorithms for estimating PBL height from remote sensing technology. Algorithms, data analysis, public accessibility and dissemination is performed with the latest cybersecurity, cloud computing, open-source services.
