Profile Summary

I hold a B.Sc. in Information Technology from the University of Derby, UK (2016) and a Ph.D. in Computer Engineering from Inje University, Korea (2024). Currently, I am a Postdoctoral Researcher at the Medical Research Institute of Pusan National University, Korea, focusing on AI-driven solutions for healthcare. My work spans multimodal medical imaging, digital pathology, and smart healthcare, with specialization in: AI/computer vision for cancer diagnostics (prostate, breast, stomach, colorectal), Neurodegenerative diseases (Alzheimer’s and Parkinson) and Computational analysis of histopathology and MRI/CT images. I have numerous SCIE-indexed publications and hold related patents. I served as a reviewer for multiple academic journals (SCIE) and as an academic editor for the journal Prostate Cancer (Wiley). Additionally, I am currently serving as a Guest Editor for the Biomedicine Journal (MDPI). Key Skills & Expertise: 1. AI/Computer Vision: TensorFlow, PyTorch, and OpenCV for medical image analysis, segmentation, classification, detection, explainable AI. 2. Medical Imaging: Advanced analysis of histopathology (H&E, MRI), computer-aided diagnosis, including nuclei segmentation, tumor-stroma ratio quantification, and cancer detection. 3. Programming & Tools: Python, MATLAB, C++, R, and web development (HTML/CSS/JavaScript). Research Projects: Ongoing: 1.
