Details

Understanding the controlling factors behind the chemical composition of the Earth’s atmosphere is a critical step toward addressing the modern environmental challenges of air pollution and climate change. Traditional methods interrogating theoretical predictions with observations have been highly successful in addressing these challenges, particularly in light of the recent immense growth of data availability in environmental systems. However, there are still gaps in our scientific knowledge due to limitations in modern scientific techniques (e.g., theoretical frameworks, observational systems, and computational power). Data-driven methods from the data science and artificial intelligence literature, when informed and guided by scientific understanding, present a valuable tool in addressing these knowledge gaps.

Sam Silva, assistant professor of Earth sciences, civil and environmental engineering and population and public health sciences at USC,  will present results from recent work using a variety of data science and A.I. methods to better constrain modern understanding of atmospheric chemistry and composition.

This event is for: alumni, community connections, faculty, staff, students

Community Connections events provide opportunities for HMC faculty, students and staff to cultivate community, foster open conversations and share important information as together we live out our mission and shape the future of the College.
