Obscured but Not Erased: Evaluating Nationality Bias in LLMs via Name-Based Bias Benchmarks
arXiv preprint
Giulio Pelosio, Devesh Batra, Noémie Bovey, Robert Hankache, Cristovao Iglesias, Greig Cowan, Raad Khraishi
Proposes a name-based benchmarking approach (derived from BBQ) to measure nationality bias when explicit demographic labels are removed, reflecting real world settings where bias can remain latent.

Evaluating the Sensitivity of LLMs to Prior Context
arXiv preprint
Robert Hankache, Kingsley Nketia Acheampong, Liang Song, Marek Brynda, Raad Khraishi, Greig Cowan
Introduces benchmarks that systematically vary prior context in multi-turn settings and shows that performance can degrade substantially as context grows — while design choices like instruction placement can help mitigate drops.

AUTOSUMM: A Comprehensive Framework for LLM-Based Conversation Summarization
ACL (Industry Track)
Abhinav Gupta, Devendra Singh, Greig Cowan, N Kadhiresan, Siddharth Srivastava, Yagneswaran Sriraja, Yoages Kumar Mantri
Presents an LLM summarization system for customer-advisor conversations with privacy/compliance safeguards, including segmentation, coverage tracking, and multi-layer hallucination detection informed by human-in-the-loop feedback.

How Personality Traits Shape LLM Risk Taking Behaviour
Findings of the Association for Computational Linguistics (ACL)
John Hartley, Conor Brian Hamill, Dale Seddon, Devesh Batra, Ramin Okhrati, Raad Khraishi
Studies how LLM “personality” relates to risk-taking via Cumulative Prospect Theory, and explores how prompting-based trait interventions can shift model risk propensity.

Representation Learning on Large Non-Bipartite Transaction Networks using GraphSAGE
Graph-Based Representations in Pattern Recognition (GbRPR)
Mihir Tare, Clemens Rattasits, Yiming Wu, Euan Wielewski
Applies GraphSAGE to large banking transaction networks to learn embeddings that reveal interpretable structure and improve downstream prioritization in a money mule detection setting.
