Sajal Debnath

Research enthusiast & Software Engineer

I am a researcher specializing in Artificial Intelligence (AI), ML/DL, and Healthcare Analytics, with a particular focus on streaming data analysis, fuzzy systems, and Medical imaging. I completed my M.Sc. in Computer Science and Engineering at the University of Barishal in 2024, where I also earned my Bachelor's degree in 2022.

My research covers various domains, including streaming data analysis and classification, AI in healthcare, and quantum DNA computing. I have published in reputable journals and conferences such as Applied Intelligence, Healthcare Analytics, and ICAEEE. I completed my Bachelor's thesis with guidance from Dr. Md Manjur Ahmed. For my Master's thesis, Dr. Rahat Hossain Faisal supervised my work. I also worked with researchers from other institutions. Together, we focused on projects in quantum-DNA and DNA-quantum, under the mentorship of Prof. Dr. Hafiz Md. Hasan Babu.

My research methodologies include adaptive learning algorithms, fuzzy systems, multi-objective optimization and imaging, with applications in healthcare diagnostics and treatment planning. I am particularly interested in developing clinically relevant solutions that bridge the gap between theoretical computer science and practical medical applications.

I am open to research collaboration or full time opportunities.
