A.I.R.E. - Ai-Assisted Reverse Engineering, Laurene Robinson

Posters - 2026

Reverse engineering plays a vital role in cybersecurity by helping analysts examine unknown binaries, investigate malware, identify vulnerabilities, and better protect sensitive systems. However, once a program is compiled and stripped, the meaningful names that describe its behavior are lost, leaving behind generic function labels like FUN_00401a30. Analysts must then manually interpret decompiled code, trace call chains, and infer program behavior function by function, which is slow and mentally demanding on large binaries. To address this challenge, this project introduces A.I.R.E., a local Ghidra extension that extracts contextual evidence from stripped functions and uses a locally hosted language model to …

Raptor Abundance And Occupancy In Urban Parks Within Metropolitan Landscapes, Mary- Esther Leblanc

Posters - 2026

Rapid urbanization is one of the most significant and accelerating drivers of global biodiversity change, reshaping wildlife communities by fragmenting habitat, altering prey availability, and introducing human disturbances. Despite these pressures, some wildlife species are attracted to and may even flourish in urban settings, primarily because urbanization creates an altered landscape that often unintentionally provides resources functioning as components of habitat. (Chiron et al., 2024) Raptors, as apex predators within avian food webs, offer a valuable lens through which to examine these dynamics. While raptor communities are broadly negatively impacted by urbanization, some species can thrive in urban areas. (Leveau …

Spinlock Game Engine, Shane Misley

Posters - 2026

Modern game engines prioritize developer convenience at the cost of performance and transparency. Large frameworks like Unity and Unreal Engine abstract away implementation details, which simplifies development but introduces computational overhead—often 40-50% of CPU and memory usage goes to engine infrastructure rather than the actual game. For developers targeting low-end hardware, older systems, or performance-critical applications, this overhead becomes prohibitive. The Spinlock Engine addresses this problem by adopting a "close-to-the-metal" philosophy, stripping away unnecessary abstraction layers to deliver raw speed and predictable behavior. Built in C++ with SDL3 and Raylib, Spinlock prioritizes memory efficiency, CPU optimization, and developer transparency—allowing you …
