Karen Casciotti
Professor

Victoria and Roger Sant Director, Earth Systems Program, Associate Professor of Earth System Science and Senior Fellow at the Woods Institute for the Environment
I am an Professor in Stanford’s department of Earth System Science. I am a chemical oceanographer, and have participated in research cruises to the Pacific, Indian, and Southern Oceans. My research is focused on how marine chemistry and biology interact to control the availability of nitrogen for marine life. In addition, I teach courses in Marine Chemistry, Marine Stable Isotopes, and Nitrogen in the Marine Environment. When not on the job, I enjoy tinkering, hiking, and exploring with my family.

I'm a PhD student in the Casciotti lab using natural abundance isotopic measurements of N2O to understand its cycling and transport. My research spans the Eastern Tropical South Pacific Oxygen Minimum Zone, the Central South Pacific, the North American West Coast, and San Francisco Bay.
Rian Lawrence
Ph.D. student in Earth System Science
Contact: rian@stanford.edu
I joined the marine biogeochemistry lab as a graduate student in September 2019. I am interested in modeling nitrate and nitrite isotope trends in the Pacific Ocean to contribute to our understanding of marine nitrogen cycling.
Hanif Sulaiman
Ph.D. student in Earth System Science
Contact: hanif@stanford.edu
I'm interested in the marine nitrogen cycle, particularly in nitrous oxide (N2O), a potent greenhouse gas that plays a key role in stratospheric ozone destruction. I'm focused on delineating nitrous oxide's accumulation (production-consumption) pathways in various oceanographic regions.
Meléa Emunah
Ph.D. student in Oceans
Contact: memunah@stanford.edu
I analyze the isotopic composition of nitrous oxide in seawater and in microbial culture samples with a focus on understanding the microbial hybrid production mechanism. My own project (starting in Spring 2023) will probe microbial nitrous oxide production in the Benguela Upwelling System.
Luke Calderaro
Ph.D. student in Oceans Contact: lukecald@stanford.edu
I am a graduate student in the Casciotti lab. My previous work in the Gulf of Mexico's "dead zone" motivates my interests in microbial metabolisms and their roles in the marine nitrogen cycle, particularly within oxygen deficient zones.
Hannah McGoran
Undergraduate student in Civil and Environmental Engineering
Contact: hmcgoran@stanford.edu
I am an undergraduate student in the Casciotti lab interested in using isotopes and biogeochemical data to understand the cycling of nitrous oxide in the Pacific Ocean. My current focus is the Eastern Tropical South Pacific and surrounding regions.

I'm the lab manager of the Casciotti group, which is to say that I try my best to keep all our instruments happy and running reliably. I also do my best to keep our group members happy by baking up lots of yummy treats in my spare time.
