Dr. Rahman's research interests are understanding and constraining the surface earth processes that control the biogeochemical cycles of nutrients, principally silica, along the land-ocean continuum and the co-evolution of the ocean and climate.

GEOL 1010 - Exploring Earth
Primary Instructor
-
Fall 2021 / Fall 2023
Introductory geology for majors and non-majors. Studies Earth, its materials, its characteristics, its dynamic processes, and how it relates to people. Separate lab (GEOL 1030) is recommended. Degree credit not granted for both GEOL 1010 and GEOL 1012.
GEOL 3320 - Introduction to Geochemistry
Primary Instructor
-
Spring 2024
Students build upon principles introduced in general chemistry in order to predict and interpret chemical dynamics in Natural environmental systems. We explores the formation and chemical differentiation of the early Earth, how chemical weathering and mineral dissolution and precipitation modifies the Earth's surface, and how redox biogeochemistry shapes aquatic environments.
GEOL 4270 - Marine Chemistry and Geochemistry
Primary Instructor
-
Fall 2024
Examines the chemical, biological, geological and physical processes affecting (and affected by) the chemistry of the oceans. Topics include: chemical cycling in seawater; the marine carbon cycle and its long-term control on atmospheric CO2; the large-scale interdependence of nutrient distributions and biological productivity, chemical tracers of ocean circulation; the chemistry of marine sediments, including early diagenesis. Same as GEOL 5270. Recommended prerequisites: introductory chemistry, introductory geology, introductory oceanography.
GEOL 4380 - Fundamentals of Stable Isotope Geochemistry
Primary Instructor
-
Spring 2022 / Fall 2023
This course teaches students the fundamental principles of stable isotope fractionation during physical and biological processes, and the application of these behaviors to a wide range of important geologic questions. The course will use classic case studies from the geologic record to illustrate these principles. Same as GEOL 5380.
