Welcome! My name is Agnese and I am a PhD Candidate in the College of Information Sciences and Technology (IST) at Penn State University, working under the supervision of Dr. Prasenjit Mitra.

I am broadly interested in how to Extract Knowledge from diverse (multimedial) data sources, in ways that support Information Retrieval, and further Acquisition and Exchange, as new Knowledge is accumulated. Lately, I have been appreciating the fun of tackling these areas for Robotic applications.


I am currently a Research Assistant at the Knowledge Media Institute (the Open University, UK), working on object detection and recognition from Robot-collected RGB and depth data, to ultimately map semantic concepts in space within a context-enriched Knowledge Base.

For the first two years of my PhD, I have worked with Dr. Lee Giles (IST) and Dr. Nilam Ram (Human Development and Family Studies) on the Screenomics project, a collaboration with the Department of Communication at Stanford University. My work has been focused on implementing a Cloud-based infrastructure for text extraction and retrieval from digital screenshots.
