PhD Recruitment, Fall 2027
Students may apply to either the Earth Science Department or the Marine Science Program.
Both of these programs provide equivalent opportunities in terms of research and TA-ships. Both programs have some (separate) internal funding mechanisms. There are two main logistical differences for PhD students: (1) Class structures - The marine science program follows a cohort model (of relatively interdisciplinary researchers) and involves a set of core courses in your first year (chemical oceanography, physical oceanography, etc). The Earth Science program has fewer formal class requirements (although you can still choose to enroll in IGPMS core courses). (2) Exams - The programs also have slightly different structures for advancement and exams.
Biogenic Organic Sulfur Isotopes: Investigate newly-observed patterns in the sulfur isotopes of marine biomass and their implications for our understanding of the global sulfur cycle. This project involves ocean-going fieldwork, the development of cutting-edge isotope methods (EA-IRMS and MC-ICP-MS), and collaborations with microbiologists to culture and model target organisms.
CO2 Removal via Biomass Storage in Anoxic Basins: Investigate the impacts and feasibility of organic carbon addition to the deep (anoxic) ocean as a means of atmospheric CO2 removal (CDR). This project involves field and lab experiments, the development of novel samplers for field applications, and cross-sector collaborations with non-profits, regulators, and startups across the nascent marine CO2 removal field.
Ideal candidates for both positions will
-
enjoy creative, hands-on problem solving
-
be internally motivated
-
have chemistry coursework and/or lab experience
-
have quantitative skills (confidence working with e.g. orders of magnitude, isotope ratios, linear systems, and the occasional PDE)
-
contribute to a collaborative, inclusive, ambitious, and positive group culture.
Preferred but not required:
-
academic research experience (M.S.)
-
professional work experience
-
interdisciplinary experience and non-traditional paths to a PhD
For more information, please answer a few questions on this Google form.
I will respond to prospective student responses in batches, so don't take it personally if I'm slow to respond. ;)
Please also feel free to reach out to other PhD students in the group to learn more! (see geol.ucsb.edu/people for emails)
