  • Brief Bio

    Nima Pahlevan is a remote sensing scientist with Science Systems and Applications Inc. (SSAI) at the Terrestrial Information Systems Lab of NASA Goddard Space Flight Center (GSFC). Formerly had been trained in geospatial engineering and remote sensing, Dr. Pahlevan earned a Ph.D. in Imaging Science from the Rochester Institute of Technology (RIT). Prior to joining GSFC in 2014, Dr. Pahlevan finished a two-year postdoctoral term working on in situ and satellite-based ocean color measurements at the University of Massachusetts Boston. His main area of research lies within the aquatic remote sensing domain with a focus on algorithm developments, atmospheric correction, calibration/validation, impacts of climate variability on water resources, harmful algal blooms (HABs), and relevant applied science practices. Dr. Pahlevan is a member of Landsat, PACE, and Terra/Aqua/SNPP Science Teams, participates in GEO AquaWatch activities, and contributes to the Surface Biology Geology (SBG) pre-formulation studies.

    Research Interests

    I lead SSAI's Freshwater Sensing Program based at Goddard Space Flight Center. My team's primary focus is developing novel machine-learning models to generate globally robust aquatic science products (e.g., water quality indicators) from multispectral and hyperspectral instruments. Our overarching goal is to deliver seamless products to end-users (e.g., aquatic scientists, water resource managers) to enable large-scale studies, and monitoring, of aquatic ecosystems. We closely collaborate with n
