About Me

I am an Assistant Professor at Virginia Tech, where I currently work as an AI Research Scientist, Digital Libraries for the University Libraries. I am also a faculty member of the Center for Digital Research and Scholarship at Virginia Tech. I completed my Ph.D. in Computer Science from Virignia Tech, in August 2024 advised by Dr. Edward A. Fox . My dissertation titled "Improving Access to ETD Elements Through Chapter Categorization and Summarization" brings computational access to long documents such as Electronic Theses and Dissertations (ETDs) by providing readers with more granular level metadata information such as chapter summaries and classification labels.

Research Interests

My primary research interest lies in Natural Language Processing, AI, Machine Learning, Large Language Models, and Digital Libraries.

Some of my current projects include:

  1. Improving natural language understanding from digital library collections:
    Methods to extract information, classify, summarize multi-modal content from digital library collections
  2. Gaining insights from historical collections through Optical Character Recognition :
    Improved OCR methods to extract text and perform textual analysis and processing on a historical document collection.
  3. Automatic identification of relevant scholarly work for systematic reviews and meta analysis :
    AI and ML methods to automate classification of relevant work in systematic reviews following a more explainable and reproducible workflow.
  4. Understanding SDG contribution in scholarly work :
    AI and ML methods for filtering and classification of scholarly work based on the contributing SDG.
