I am currently a Visiting Assistant Professor in School of Information (iSchool), College of Communication & Information at Florida State University. Prior to this I was a Post Doctoral Fellow at eHealth Lab at iSchool in FSU working under Prof. Zhe He. Prior to this I was a Post Doctoral Fellow at The Bakar Computational Health Sciences Institute (BCHSI), University of California, San Francisco under Dr. Vivek Rudrapatna in the The Real-World Evidence Lab. I have a Ph.D. in Biomedical Informatics under Prof. Jeyakumar Natarajan in the DRDO-BU Center for Life Sciences, TamilNadu, India. I am a proud member of the eHealth Lab @ FSU, Real World Evidence Lab @UCSF, Data Mining and Text Mining Laboratory @BU and Computational Biology Division @ DRDO-BU CLS.
I am a researcher specializing in Information Extraction and Machine Learning within Clinical Data Science and Biomedicine. My current work centers on Clinical NLP, Machine Learning, and Generative AI. With over 10 years of experience, I have developed various classification and prediction models using biomedical data. My interests include causal inference, literature-based discovery, network visualization, knowledge graphs, and ensuring fairness and explainability in machine learning models.
