My current research focuses on understanding how external forcings, including extreme solar activity and major volcanic eruptions, have shaped and influenced Earth's climate system.
I aim to investigate the fingerprints of these events across different climatic states, such as glacial, mid-Holocene, present, and future, by integrating Earth-system modeling with proxy-based reconstructions.
This involves:
- Extreme Climate events
- Earth-system model development and implementation
- Analysis of radiative and chemical feedbacks
- Big data processing and analysis of long-term climate series using multivariate statistics and machine learning algorithms
- Tracer transport and deposition modeling under glacial, present, and future scenarios
