Environmental Science and Engineering;
Profile
My research is broadly focused on the global carbon cycle, especially using the vantage point from space (or air) to obtain a truly global (or regional) view on specific phenomena occurring at the interface between the Earth Surface (including terrestrial biosphere and anthropogenic activities) and the atmosphere. My current focus is on the study of solar induced chlorophyll fluorescence as well as atmospheric methane and carbon dioxide.

ESE 103. Earth's Biogeochemical Cycles.
9 units (3-0-6); second term, 2021-22.
provide a basic introduction to Global Biogeochemical cycles, with a focus on drivers of the global biosphereFor course description, see Computer Science.. Topics to be covered include fundamentals of photosynthesis and its quantitative formulation, impact of nutrients, microbial processes underlying weathering, decomposition, and carbon remineralization, box modeling, hydrological cycle, land surface energy balance and basics of land surface modeling, ecosystem processes and the human footprint. Scripting (Matlab) knowledge useful for homework sets.

ESE 156. Remote Sensing of the Atmosphere and Biosphere.
9 units (3-0-6); first term, 2021-22.
Prerequisites: ESE 101 or instructor's permission.
An introduction into methods to quantify trace gases as well as vegetation properties remotely (from space, air-borne or ground-based). This course will provide the basic concepts of remote sensing, using hands-on examples to be solved in class and as problem-sets. Topics covered include Absorption spectroscopy, measurement and modeling techniques, optimal estimation theory and error characterization, applications in global studies of biogeochemical cycles and air pollution/quality. This course is complementary to EE/Ae 157ab and Ge/EE/ESE 157c with stronger emphasis on applications for the atmosphere and biosphere. Students will work with real and synthetic remote sensing data (basic knowledge of a scripting language is advantageous, most of the examples will be in Julia). Not offered 2021-2022.
