Hidden Behavioral and Reliability Failures in Multi-Agent LLMs Beyond Task Accuracy
Hi, I'm Lia
My work lies in intelligent agents, natural language processing, human-centered applications and secured decentralized systems, with experience in large-scale software and LLM development
I have started working as a Research Assistant at the University of Toronto (working with Dr. Ishtiaque Ahmed and Sheza Munir); and a Research Fellow at Spar AI, Berkeley and Fatima Institute for Global AI Research, California.
I was a Research Intern at Aramco-Ithra, collaborating with global institutions including WHO, Stony Brook Medicine, University of Washington, University of Geneva, University of Tokyo and research institutes from 35 countries. Previously, I worked with the United States Department of Justice - ICITAP, designed a platform for secure crowdsourced crime reporting in low-connectivity areas, leveraging custom NLP pipelines, geospatial and predictive models.
I recently graduated (Top 5) with a degree in Software Engineering (concentrating in AI and NLP) from the University of Dhaka where I work in BARTA Lab. There, I worked on low-resource and small-language-model development. I serve as an instructor at BARTA, where I teach a language model building course . I am also serving as an Instructor for International AI Olympiad, teaching AI Recommender Systems, and a Judge at BDAIO.
Entrepreneurially, I was a founding member of Perspectivity - Drishtikon, the first real-time AI news aggregator for Bangla, featuring multi-axis bias detection that empower citizens with research agents.
And... I paint.
