Research, Reproducibility & Trustworthy Synthetic Cybersecurity Data

I build reproducible research infrastructure and evaluation methodologies for synthetic cybersecurity data, malware-image classification, and trustworthy machine learning. My work emphasizes downstream utility, probabilistic reasoning, external conditioning audits, uncertainty, calibration, and systems-aware evaluation that scales into reliable research and engineering infrastructure.

Research Progression

Research Roadmap

A staged progression from reproducible synthetic-data benchmarking to trustworthy evaluation and scalable, systems-oriented research infrastructure.

Foundational Benchmarking

Establish realistic, leakage-safe, and reproducible synthetic-malware benchmarks through standardized datasets, preprocessing, model families, budgets, seeds, metrics, and downstream evaluation protocols.

Established foundation

Utility & Policy

Determine when synthetic augmentation improves classification, where it fails, and how data should be allocated, filtered, ranked, selected, or rejected under constrained budgets.

Active research program

External Conditioning & Causality

Audit whether conditional generators satisfy requested labels, diagnose class leakage and collapse, and extend observational audits toward randomized and causal analyses of external influences.

Audit foundation established

Trustworthy Evaluation

Advance calibration, uncertainty estimation, robustness, abstention, risk-sensitive metrics, distribution-shift analysis, and reliable security decision-making.

Planned next research stage

Systems & Research Infrastructure

Build reproducible, artifact-backed, performance-aware research tooling and gradually connect machine-learning evaluation with systems, compilers, runtimes, memory, parallel execution, and high-performance computing.

Long-term systems direction
The roadmap represents research progression rather than a rigid schedule. New studies can be inserted into the appropriate stage as the program develops, without changing the overall structure.
Long-Term Research Vision

Looking Ahead

My long-term vision is to connect trustworthy machine-learning research with systems-level impact. I aim to build reproducible research infrastructure, performance-aware tooling, and scalable evaluation frameworks that make security models easier to audit, reproduce, optimize, and deploy reliably. As my systems expertise deepens, this work will increasingly connect with memory, parallel execution, compilers, runtimes, and high-performance computing.
