Doug Schuster is the acting director of CISL’s Information Systems
Division (ISD) and manager of ISD’s Data Engineering and Curation
Section. ISD develops and maintains services that enable search and
discovery of NCAR’s data assets, support data-proximate computational
research, and provide long-term preservation and access to the rich
variety of observational data sets and model outputs produced and
hosted at NCAR. Additionally, ISD offers consulting services to its
data services users and assists NCAR researchers in developing data
management plans that meet community open science expectations. Doug
earned his bachelor’s degree in civil engineering at the University of
Minnesota, Twins Cities, and an M.S. in atmospheric science at
Colorado State University in Fort Collins.

Ben attended the University of Texas at Austin, earning his BS and PhD in Aerospace Engineering, with a MS in Computational & Applied Mathematics.  He worked at NASA’s Lyndon B. Johnson Space Center for 18 years prior to joining NCAR.  His background includes constructing and using HPC systems (compute and storage), particularly for fluid dynamics simulations

Sheri Voelz has over 20 years of experience as a research software engineer working on Earth Science models. Throughout her career, she has focused on accelerating modeling codes, workflows, and IO. Sheri currently manages a group of software engineers within CISL focused on porting NCAR models onto GPUs, optimizing IO workflows, and exploring future architectures. In addition, she is the lead software engineer on the EarthWorks project, which is focused on running climate simulations at storm-resolving resolutions. She is also passionate about mentoring underrepresented groups in computational science and advocating for research software engineers and their important roles in scientific discovery.

Dr. David John Gagne II is a Machine Learning Scientist II and head of the Machine Integration and Learning for Earth Systems (MILES) group at the NSF National Center for Atmospheric Research (NCAR) in Boulder, Colorado. He has led the development of machine learning systems that enhance understanding and prediction of high impact weather and critical Earth system processes. He received his Ph.D. in meteorology from the University of Oklahoma in 2016 and completed an NCAR ASP Postdoctoral Fellowship before assuming his current role. He is a NSF AI2ES AI Institute leader and a NSF LEAP Science and Technology Center member. He is a WMO Nowcasting and Mesoscale Research Working Group member, chaired the American Meteorological Society Artificial Intelligence Committee, and serves as an editor for the AI for the Earth Systems journal, and has led summer schools, short courses, and hackathons.

Moha Gharamti is a Scientist II at the Computational and Information Systems Laboratory (CISL) at the NSF National Center for Atmospheric Research (NSF NCAR). He earned his bachelor's degree in Geological Engineering from the Middle East Technical University in Ankara, Turkey, and later obtained his PhD in Earth Sciences and Engineering from King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia. Following his PhD, he completed an 18-month postdoctoral fellowship at the Nansen Environmental and Remote Sensing Center (NERSC) in Bergen, Norway. Gharamti has been an integral part of NSF NCAR for 8 years, contributing significantly to the advancement of data assimilation (DA) science.

Gharamti's expertise lies in both sequential and variational data assimilation methodologies, with a particular focus on the ensemble Kalman filter (EnKF). His research centers on developing innovative, efficient, and robust DA algorithms applicable across a wide range of Earth system models. His contributions span various geoscience applications, including atmospheric science, ocean biogeochemistry, hydrologic forecasting, and flood prediction. He is one of the lead developers of the Data Assimilation Research Testbed (DART), a widely used tool within the academic community and internationally.

Dr. Negin Sobhani is an HPC consultant at the NSF National Center for Atmospheric Research (NSF-NCAR).  Her focus is on adopting emerging computational technologies to improve the performance and usability of earth system models and data analysis workflows.  She has extensive experience in HPC, Earth System Modeling, AI/ML, big data analysis, and interactive visualization, which enables her to assist users from diverse backgrounds in leveraging these technologies to advance their scientific endeavors.

Negin earned her Ph.D. in Chemical Engineering from the University of Iowa in 2017, where she focused on developing and optimizing regional weather and air quality models.  She began her full-time journey at NCAR as an Advanced Study Program (ASP) postdoctoral researcher and then worked in the Climate and Global Dynamics (CGD) division before her current role in the Computational and Information Systems Laboratory (CISL).
