Dr. Katia Lamer is an atmospheric scientist and the Director of the Center for Multiscale Applied Sensing at Brookhaven National Laboratory. She specializes in atmospheric boundary layer processes, shallow convection, and remote sensing technology, with a strong emphasis on data science, including the application of artificial intelligence to geosciences. Her work bridges fundamental atmospheric research with real-world applications, developing innovative tools to enhance weather prediction, environmental monitoring, and resilience planning.

Originally from Canada, Dr. Lamer earned a B.Sc. in Earth System Science and an M.Sc. in Atmospheric and Oceanic Sciences from McGill University. She then pursued a Ph.D. at Penn State University under Dr. Eugene Clothiaux, focusing on integrating ground-based remote sensing observations with global weather models to improve the representation and simulation of mixed-phase clouds. As part of this work, she developed the (GO)²-SIM instrument forward simulator, an objective tool for translating physics-based model outputs into observables.

Following her Ph.D., Dr. Lamer conducted postdoctoral research at the City College of New York with Dr. Jimmy Booth, studying how large-scale weather patterns influence rainfall properties in subsidence regimes. Since joining Brookhaven, she has focused on identifying and addressing critical atmospheric data gaps, particularly in complex environments such as cities and coastal regions. Her research has helped reveal limitations in CloudSat satellite observations, contributing to the design of its successor, EarthCARE for improve characterization of boundary layer clouds. 

Dr. Lamer has also played a key role in advancing observational technologies, including the first time-gated, time-correlated single-photon counting lidar and of THz radar for probing cloud and rain formation. She led the design, construction, and deployment of Brookhaven’s mobile observatories—off-grid, truck-based measurement platforms engineered for rapid deployment where data is most needed. These observatories are actively filling data gaps across the US, supporting research on extreme heat mitigation, urban air mobility, and atmospheric dispersion for emergency planning.
