Heidi M. Sosik, Ph.D.Senior Scientist, Biology Department, Woods Hole Oceanographic Institution
Presidential Lectures are free public colloquia centered on four main themes: Biology, Physics, Mathematics and Computer Science, and Neuroscience and Autism Science. These curated, high-level scientific talks feature leading scientists and mathematicians and are intended to foster discourse and drive discovery among the broader NYC-area research community. We invite those interested in the topic to join us for this weekly lecture series.
Diverse microscopic organisms dominate life in the ocean. Marine microbiomes are complex and highly dynamic, responding rapidly to their ever-changing fluid environment. They fuel marine food webs and contribute substantially to global scale productivity, nutrient cycling and climate regulation. Yet, many aspects of how the ocean’s microbial communities are structured and respond to change remain poorly understood, mainly because they are so challenging to observe in nature at relevant space and time scales. High throughput robotic microscopy and cytometry are now filling this gap, providing the capability to measure multi-decade species-specific time series and quantify impacts of microbial interactions such as phagotrophy, parasitism and symbiosis in the ocean.
In this Presidential Lecture, Heidi Sosik will highlight discoveries emerging from the combination of machine learning and billions of images of microbial ocean life.
