Jeremy Werdell is an Oceanographer in the Ocean Ecology Laboratory (OEL) at NASA Goddard Space Flight Center (GSFC) and the Project Scientist for the upcoming PACE mission. He received his Bachelors of Arts in Biology and in Environmental Science from the University of Virginia in 1996, his Masters of Science in Oceanography from the University of Connecticut in 1998, and his Doctor of Philosophy from the University of Maine in 2014. Jeremy has worked in the OEL Ocean Biology Processing Group since 1999, where he now serves as a senior leader of several tasks, and has served as the PACE Project Scientist since 2015. Jeremy currently oversees the SeaWiFS Bio-optical Archive and Storage System (SeaBASS), NASA bio-Optical Marine Algorithm Data set (NOMAD), and OEL in-water bio-optical algorithm development efforts. His research interests extend to the on-orbit calibration of ocean color satellite instruments, the validation of remotely-sensed data products, the collection and analysis of in situ biogeochemical oceanographic measurements, and the assimilation of the above to study how the global ocean and various regional ecosystems are changing with time. When time permits, Jeremy moonlights as a teacher and student mentor (and wannabe chef). He has led several internationally attended workshops on bio-optical algorithm development and helped instruct undergraduate and graduate-level courses on ocean optics and biology.
