To understand changes in the carbon cycle on both

human and geological timescales, we need to understand how carbon, sulfur, oxygen, nutrients, and metals interact in the environment.

In NOISE Lab at UCSB, we develop and use a variety of cutting-edge analytical tools to study these interactions at the interface between geobiology and geochemistry.

How does sulfur biogeochemistry affect organic matter cycling?

Dr. Morgan Reed Raven

Morgan is an organic geochemist and geobiologist. After finishing her PhD at Caltech in 2016, she worked as an Agouron Geobiology Fellow at Washington U. in St Louis before joining the UC Santa Barbara Earth Science faculty in July 2018.

Morgan's research includes classic and emerging problems in biogeochemistry, ranging from the origins of life to modern and ancient climate change. A common thread shared by many of these questions is an under-studied role of organic sulfur. Her lab specializes in sulfur isotope analysis by multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS), a powerful tool for measuring very small samples from a wide range of environments.

NOISE Lab is looking for a PhD student to start in ~Fall 2021!

If you're excited to think about either:

* organic matter transformations in marine anoxic zones, OR

* using sulfur isotope records to reconstruct ancient environments,

please reach out! I'd love to hear from you.
