Research Summary

My research focus is on developing efficient and accurate algorithms for data analysis in biomedical research. I wish to understand the foundations of data analysis and idiosyncrasies of biomedical data towards developing scientifically interpretable algorithms. Originally trained as a computer scientist, I have studied data analysis in biomedical research for over 6 years during my Ph.D. and postdoctoral research. My research interest is to develop algorithms for biomedical applications such as medical imaging, bioimaging, and public health research. My previous and current work has involved several major areas: (a) Developing novel inversion algorithm for deformation field with theoretical guarantee of accuracy and convergence; (b) Developing alternating symmetric completion algorithm for image registration; (c) Designing statistical features of time-series data extracted from single-molecule fluorescence images for barcoding; (d) Developing probabilistic deep learning model for information extraction from medical reports; e) Model reduction of shallow CNN model for reliable and interpretable deployment; (f) Developing domain detection and adaptation algorithm for generalization of DL models to multi-center dataset. I have authored 10 scientific papers and 5 abstracts in peer-reviewed conferences and journals. A complete list of my previous publications is included in my full CV. I am also serving as a reviewer in scientific journals Journal of Biomedical and Health Informatics , Neural Processing Letters, and IEEE access.

I am on the job market (2020-21). You can find my research statement here and slides here.
