I am Professor of Geography at Ohio State. I have a broad range of research interests in geographic information science. My major research areas include spatial optimization, spatial and temporal data analytics, cartography, and human and environmental modeling. Please visit my Research page for a list of my publications by area.
I am a huge fan of open source software development. Please visit gis.osu.edu for some highlights of my teaching and research using open source tools in spatial and temporal data analytics. I also maintain a github site at https://github.com/ncxiao, where the web development examples can be found at https://ncxiao.github.io.
