What I'm looking for

I seek data science or ML roles applying AI-driven solutions to real problems, with opportunities for research impact, collaboration, and professional growth.

I am a Ph.D. candidate in Computer Science specializing in Information Security with a research focus on Data Science, Machine Learning, and Deep Learning. I bring over three years of research experience, one year of teaching, and extensive internship work in data science.

My work has produced multiple SCI-indexed publications and under-review transactions in high-impact venues, reflecting strengths in privacy-preserving encryption, access control, and secure IoT/healthcare systems. I combine strong theoretical foundations with practical model-building skills.

I have built and deployed ML pipelines and performed large-scale data analysis—projects include social media disaster analysis, tweet classification/summarization, and smart-grid appliance prediction with high reported accuracies and efficiency gains. I am proficient in Python, R, TensorFlow, SQL and common data science libraries.

I seek to apply AI-driven solutions and predictive modeling to real-world problems, bringing rigorous research experience and hands-on engineering to data science, ML, and security-focused roles.
