Research Interests
My research focuses on using the molecular and isotopic composition of organic biomarkers to understand the source, cycling and fate of organic compounds in the present and past ocean. Current projects include:
  1. Development of new compound-specific radiocarbon dating methods to determine the age of sedimentary organic matter.
  2. Analysis of the radiocarbon composition of lipid biomarkers from bacteria and archaea to understand their metabolism and ecology.
  3. Identification and isotopic analysis of organic compounds in diatom frustules.
  4. Investigation of the relative importance of ammonia oxidizing archaea and bacteria in the environment.
  5. Polar lipids as biomarkers of terrestrial organic carbon deposition in marine sediments.


OCEAN 201 Introduction to Oceanography Lab (2) NW - course web site

Ingalls - Provides opportunities to experiment with oceanographic concepts through laboratory and field experiences, and learn about the scientific method of inquiry as it applies to the study of geology, physics, chemistry, and biology of the ocean. Emphasizes topics that explore current challenges faced by the ocean and its ecosystem. Co-requisite: OCEAN 200. Offered: Sp.

Class description In this course you will have the opportunity to gain hands on experience with the concepts presented in Ocean 200. Each week’s activities are designed to highlight a fundamental question in ocean research.

Student learning goals Through these activities you will learn how we develop a scientific appreciation for the world we inhabit.

At the end of this class, we hope you will be able to read lay reports of scientific studies and think critically about how the study was designed and what the results really mean.

This class will teach you to understand how we do science and will therefore give you a better appreciation of the role that science plays in your everyday life.

General method of instruction Students will work in small groups to carry out in class lab experiments.

Recommended preparation There are no prerequisites but this class is designed to be taken by students also enrolled in Ocean 200.

Class assignments and grading We will do a lab in class each week and students will hand in a report one week after the lab is completed in class.
