Current Group Members
Bren Cable - MS candidate
Bren worked at the interface of mineralogy, soil science and water geochemistry. She investigated how the presence of Ca bearing minerals might impact ecosystem resilience in acid impacted watersheds. Bren has been gaining a lot of experience in field work and communicating science in conferences and our "cluster chats". She just successfully defended her thesis! |
|
Niara Hicks - MS candidate
Niara worked on the connection between hydrology and biogeochemistry. She investigated patterns in water quality data in connection with catchment attributes in an iterative fashion. Niara has been honing her data analyses skills and also joined fieldwork regularly (including a trip to Yosemite with Bren). She successfully defended her thesis in Fall 2024! |

Elliott Bloom - Undergraduate Researcher
Elliott finished her undergraduate thesis in where she worked on a geochemical model for soil core effluents. She analyzed a variety of data and also managed data upload to Earthchem. Ultimately she will be going to grad school and talked with our project outreach coordinator Andrew about her plans. |

Andrew Cassel - Outreach and Process Coordinator
Andrew is managing outreach for the CZNet Big Data cluster, including our social media presence, newsletters, and "Cluster Chats". There is no Big Data event where he is not instrumental in making it happen (and many of the pictures you see from events here and on the project homepage are taken by him)! Andrew also makes guest appearances in courses where he talks about science communication and the role of social media, and regularly covers AGU. |
