Ratna Saripalli
Chief Data Officer

Dr. Ratna Saripalli, PhD in artificial intelligence and machine learning, is the chief data officer of the Environmental Molecular Sciences Laboratory (EMSL). With over 20 years of technology leadership experience shipping enterprise data platforms and products, Saripalli leads EMSL's high-performance computing and data platform infrastructures. She works closely with platform and software engineers, data architects, computer scientists, and cybersecurity engineers to develop and deliver EMSL's overall digital infrastructure vision and strategy.  

As a technology leader and software engineer, she has industry experience in conceiving, implementing, and managing artificial intelligence, machine learning, data engineering, and analytics products and platforms. Before rejoining Pacific Northwest National Laboratory (PNNL), she served as the vice president of technology at Berkeley Lights, in charge of developing computational methods for large datasets such as gene expression, metabolomics, and proteomics. Before that, she was a senior global director of data science at GE HealthCare for three years, developing world-class artificial intelligence products to revolutionize health care and improve clinical outcomes. She won the GE HealthCare Key Innovator award twice and has contributed to several patents and publications. She served at Microsoft for 11 years in various lead roles, helping ship Bing AdCenter, Office365, and Windows Data Science and Engineering products. Before joining Microsoft, she was a research scientist at PNNL for six years, contributing to global research projects pivotal to genomics and life sciences.
