I am a broadly trained quantitative Earth System scientist, interested in various topics of Oceanography, Remote Sensing/GIS and Environmental Geography. My main expertise is in marine bio-optics and ocean color remote sensing. I work on satellite algorithm development that aims to improve our understanding of ocean ecosystems and biogeography. I also conduct research in snow remote sensing in conifer forests. Water and remote sensing are common unifying themes of my research. A third line of research I pursue is related to Earth’s orbital cycles that affect climate (Milankovitch cycles) and related astronomical visualizations. I also have interests in related disciplines, e.g. physical basis of climate and climate change, paleoclimatology, botany and plant systematics (focusing on trees), forest ecology & vegetation remote sensing, and positional astronomy. My research makes heavy use of scientific computing, modeling, and data processing and visualization; I am interested in scientific and technical computing per se.
