About Me


I am a tenure-track assistant professor in the Department of Data Science at New Jersey Institute of Technology, also a joint faculty with the Department of Computer Science. I am previously a research fellow with Prof. Timothy Miller and Prof. Guergana Savova in the Computational Health Informatics Program (CHIP) at Boston Children's Hospital and Harvard Medical School. I completed my Ph.D. of Computer Science at the University of Virginia, co-supervised by Prof. Madhav Marathe and Prof. Jiangzhuo Chen.

[05/01/2023] Openings are all filled: I am looking for highly motivated students (including PhDs, Masters, undergraduates) to join my group. Please check the opening positions if you are interested in working with me.

Research Interests


I am broadly interested in artificial intelligence, machine learning, deep learning, natural language processing, time series analysis, and network science with the emphasis on solving societal challenges. My Ph.D. dissertation research focuses on combining theory-based mechanistic models and deep neural networks for epidemic forecasting. More specifically, my research focuses on deep learning-based methods that incorporate theory-based causal models, spatio-temporal features, multi-source data analysis, and ensembling techniques for a better understanding of disease spreading and improving forecasting accuracy, explainability, and consistency. My current research focuses on clinical NLP with emphasises on fine-tuning methods for digital curation of Electronic Medical Records (EMRs) and deep learning-based methods for classification of Electronic Health Records (EHRs).
