Dr. Julie Lattaud studied geology in France and received her PhD at Utrecht University in 2019. Her Thesis focus was on developing new tools to reconstruct past climate. Her current work at ETHZ focus on the carbon cycle in the Canadian Arctic and how it has changed in the past 200 years. Her recent expedition in the Beaufort Sea seeks to understand how the biological methane cycle has changed during the Holocene, to better forecast how it would change in the (near) future. She uses organic geochemistry techniques to identify remnant of microbes involved in the methane cycle, which will allow her to trace and reconstruct their activity through time.
