AI and Cybersecurity Researcher

Aug 2024 - Present • 2 yrs 1 mo

At NUST University my research focuses on cybersecurity, privacy-aware AI and machine learning, particularly encrypted network traffic and application classification. I work with large datasets, prepare and document raw data, analyze missing values and class imbalance, derive and evaluate features, train baseline models and compare results through reproducible Python pipelines. I also work on adversarial machine learning, including FGSM-based experiments, data visualization, model evaluation and technical reporting. My approach emphasizes realistic datasets, transparent methodology and careful interpretation of results. I have also contributed to published research involving adversarial machine learning and FGSM-based robustness evaluation.
