Maria Pachiadaki is a Marine Microbiologist at Woods Hole Oceanographic Institution (WHOI), USA. Maria aims to unveil the mysteries of the microbial life of the aphotic ocean realm. She is particularly interested in the identity, function and activity of the microorganisms inhabiting oxygen-depleted marine systems, and their effects on global ecosystem processes. She also works on the development of technology for in situ studies in marine microbial ecology and biogeochemistry.

Maria received her B.Sc in Biology and her M.Sc in Biological Oceanography from the University of Athens, Greece. She earned her Ph.D. from the University of Crete and moved to Germany and then to the USA for postdoctoral work. She joined the Faculty of WHOI’s Biology Department at the end of 2018. Maria received the Early Career Investigator in Microbial Ecology and Evolution Award in 2022 from Simons Foundation and the 2023 Early Career Scientist Award from WHOI. She has participated in 19 oceanographic expeditions.
