The risk of forest fires is expected to increase as the global mean temperature rises due to climate change. I am investigating how climate change will impact the risk of forest fires in Canada.

Methane is the second most important atmospheric greenhouse gas. Its concentration has tripled since pre-industrial times, causing a rise in global temperature of ~0.6 °C. Methane is also a precursor for air pollution because its oxidation produces ozone in the troposphere, a toxic air pollutant. Since methane has a lifetime of ~9 years in the atmosphere, decreasing methane emissions will likely result in a rapid decrease in the warming and pollution it causes. I am interested in investigating how future methane emissions will affect the climate system.

The Great Oxidation Event (GOE) marked the end of the Archean Eon (4-2.5 Ga) and the start of the Proterozoic Eon (2.5-0.5 Ga) 2.5 Giga years ago (Ga) with a substantial increase in the atmospheric oxygen content and the transition of the Earth surface from reducing to oxidizing conditions. I am interested in understanding the causes of this extraordinary event, which has important implications for the history of the evolution of the Earth's atmosphere and the development of life. Also, I am interested in understanding the effects of this event on climate, which could have important implications for our understanding of the evolution of the Earth and other planet's climate system.
Here are two publications about my research on the GOE:

1. Climate shapes the oxygenation of Earth's atmosphere across the Great Oxidation Event. Earth and Planetary Science Letters. 2023.
2. Climate Variability Leads to Multiple Oxygenation Episodes Across the Great Oxidation Event. Geophysical Research Letters. 2024

I am interested in the mathematical modeling of atmospheric chemistry processes. The atmosphere's composition varies on short and long time scales due to meteorologic, climatologic, radiative, chemical, and biogeochemical processes. I am interested in using and developing atmospheric chemistry models to understand the variability and evolution of the Earth and other planets' atmospheric composition.
Here is one publication about my research on atmospheric chemistry:

I am interested in using and developing biogeochemical models to investigate the evolution of the interactions between different Earth systems through Earth's history. In particular, I am interested in the coevolution of life and the environment.
