Research Interests
I am interested in mathematical modeling for real-life problems.
• Mathematical approaches to image processing: image denoising, segmentation, color image processing, surface reconstruction, pattern analysis, etc.
• Machine learning theory and data analysis: differential equation reconstruction, model selection, statistical test, natural language processing etc.
• Mathematical biology: immune system modeling, cell expansion modeling, etc.
• Variational analysis, stochastic analysis, numerical analysis, differential geometry, and geometrical color theory.
• Linguistics.
