Research & Development Experience

Postdoctoral Researcher at the Luxembourg Institute of Science and Technology, Luxembourg from March 2024 to Present

Aayush is developing new methods by employing DL/LLMs to improve the security of SDLC by identifying software vulnerabilities.
He is employing AI solutions to prevent cyber attacks utilizing Fuzzers, by automatically detecting such attacks and by implementing software self-healing solutions focusing on automatically generating vulnerability patches.
He is developing automated solutions to identify the attack vectors (in the context of a 5G-core network) and to prevent an unauthorized user from entering or extracting data from the environment.

Aayush designed solutions harnessing AI, especially Deep Learning to automatically define and learn features from source code representation replacing 100% manual effort.
He trained Neural Networks and Machine Learning models to achieve task-specific classifications with up to 87% Precision and Recall.
He employed LLMs and GPTs to induce artificial faults enabling up to 65% increased test effectiveness in detecting zero-day vulnerabilities.

Aayush conducted lectures on the “Introduction to Machine and Deep Learning” to Bachelors in Computer Science (BICS)
Lecture series (videos) on the “Introduction to Machine and Deep Learning” are available here. The videos were uploaded to make lectures available to students during the COVID-19 lockdown period.
He also taught “Introduction to Software Testing” to Bachelors in Applied Information Technology (BINFO)
