Biography

I study vegetation-climate interactions in the context of climate change. My research work includes spatial ecology, plant physiology, remote sensing, and climate change. Specifically, I am interested in the climatic controls on vegetation photosynthesis and related plant functioning, the feedbacks of vegetation to the climate, and the impact of climate change on vegetation phenology. I develop novel approaches to quantify photosynthesis and leaf traits remotely, and I use advanced computation approaches such as data assimilation to bridge the gap between observations and models to improve our predictions of carbon, water and energy fluxes.

EVSC 4010: Introduction to Remote Sensing
Credits: 4
Introduction to the physics and techniques of remote sensing. Prerequisite: at least one year of college-level chemistry or physics, or instructor permission.
EVSC 4012: Advanced Remote Sensing
Credits: 3
Remote sensing is a technique to obtain data about an object without physical contact with it. It is a powerful tool for extracting quantitative information about Earth's surface and subsurface. As an upper-level class in remote sensing, in this seminar, we will focus on advanced remote sensing techniques at different spatial scales that help to gain information about the biosphere, atmosphere, and hydrosphere.
EVSC 4559: New Course in Environmental Science
Credits: 1–4
This course provides the opportunity to offer a new topic in the subject area of environmental science.
EVSC 4993: Independent Study
Credits: 1–6
Specialized topics in ecology, atmosphere, hydrology, environmental geology, or environmental systems not normally covered in formal classes under the direction of the faculty. Prerequisite: Instructor permission.
EVSC 4995: Supervised Research
Credits: 1–6
Original research usually involving a field or laboratory problem in the environmental sciences under the direction of one or more faculty members. The results may form the basis of an undergraduate thesis which is required to partially fulfill the Distinguished Majors Program in environmental sciences. Prerequisite: Instructor permission.
EVSC 4999: Thesis Research
Credits: 3
Provides credit for doing work in pursuit of the undergraduate thesis option for majors in Environmental Science
EVEC 5220: Terrestrial Ecology
Credits: 4
Analyzes the patterns and processes in terrestrial ecosystems. Topic include macro- and micro-meteorological factors such as producer, consumer, and decomposer processes; hydrologic and biogeochemical pathways; and changes through space and time. Three lecture and four field or laboratory hours. Prerequisite: EVSC 3200 or equivalent, and instructor permission.
