Overview

Post-Doctoral Fellow - Computer Science (Cybersecurity)

Tracking Code : req1835

Faculty of Business and Information Technology

Number of Positions : 1

Appointment Type : Limited Term

Salary Grade : Administered in accordance with the Collective Agreement

Posting Date : November 19, 2025

Closing Date : February 26, 2026 (7 : 00 pm EST)

The Faculty of Business and Information Technology at Ontario Tech University has an opening for a Postdoctoral Fellow (PDF) in the area of Cybersecurity and AI. The position is offered for 12 months, preferably starting January 1, 2026, subject to funding approval and may be extended contingent upon research performance.

This research program investigates the use of large language models (LLMs) with code-synthesis capability to automate metamorphic malware generation. The goal is to understand how modern foundation models—when fine-tuned on malware code corpora—can learn transformation rules that produce functionally-equivalent variants capable of bypassing static and signature-based detection.

The broader objective is to provide defensible, repeatable measurement of how AI-assisted metamorphic code generation may change the offensive–defensive balance—and to surface threat-relevant insights for defensive counter-design (e.g., more semantic detection and de-obfuscation strategies).

The position will be supervised by Dr. Pooria Madani.

Responsibilities

• Dataset preparation and domain-specific fine-tuning of LLMs for code mutation
• Model compression / quantization to make such models small enough for endpoint-size deployment scenarios (threat modelling angle)
• Formal and empirical verification that mutated samples preserve semantics (correctness safety checks)
• Automated validation pipelines to measure detection evasion against commercial AV / EDR engines
• Controlled experimentation to quantify detection degradation after each class of code-level metamorphic transformation
