Welcome!

My research interests include automatic image tagging / recognition, climate informatics, biomedical informatics, computability of aesthetics and emotions, semantics-sensitive image retrieval, story picturing, art image analysis and retrieval, and image security. I am currently leading a group of doctoral students and undergraduate research students at Penn State to explore these areas. For more information, click on research or visit my Scholar profile.
