Despite multilingual pretraining, large language models often struggle with non-English tasks, particularly in language control — the ability to respond in the intended language. We identify and characterize two key failure modes: the multilingual transfer bottleneck (correct language, incorrect task response) and the language consistency bottleneck (correct task response, wrong language). To systematically

Personalized experiences in multimodal assistants rely on accurate user understanding, yet large-scale training for personalization remains limited by privacy constraints and data sparsity. We introduce a framework for generating Comprehensive Synthetic Personas (CSPs) and personalized synthetic training data through taxonomy-guided knowledge enrichment, in-context learning, and Chain-of-Thought (CoT) knowledge

As AI agents become collaborative partners in complex tasks, understanding how agent personality affects human-AI interaction becomes critical. While recent work explores personality customization in language models, little is known about how personality affects AI coding agents. We conducted the first exploratory study investigating: if OCEAN (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism

Our team integrates expertise in human-AI interaction and robust LLM agents. We study how latent risks emerge in AI-generated software through realistic user-driven collaborative development, leveraging failure attribution and adaptive inference to uncover and operationalize these risks, driving innovation in trustworthy software agents.

Our team is exploring how multi-agent AI systems can improve automated security testing for modern web applications. We aim to combine LLM reasoning and pattern recognition capabilities with structured tool usage within an agentic workflow to emulate realistic security analysis processes. In parallel, we are designing a robust user-simulator that effectively interacts with coding agents of diverse capabilities to produce functional web applications.

Our goal is to advance functional correctness, reliability, and security in AI-driven software development and testing through two complementary efforts: (i) building coding agents that generate high-quality and reliable software via advanced planning and adaptive guidance, and (ii) developing next-generation red-teaming systems that effectively detect and exploit vulnerabilities in generated software by combining Large Language Model reasoning, security domain knowledge, and program analysis.

Our team is exploring autonomous red teaming for complex web applications, with a focus on vulnerabilities that emerge across application state, multiple code paths, and iterative interaction. We hope to contribute ideas in state-aware reasoning, repository-level analysis, and runtime feedback-guided validation.

The Slugs N' Roses team studies the intersection of AI, software engineering, and cybersecurity. In the Nova AI Challenge, we are developing AI agents that learn to write secure code through post-training techniques, enabling them to implement software features while reasoning about security risks introduced during development. Our broader goal is to enable AI-assisted development workflows that are both highly capable and fundamentally secure.

We aim to develop a system that combines a reliable code agent with a user simulator to enable interactive, adaptive problem solving. Our approach emphasizes safe behavior while leveraging simulated user feedback for scalable training and evaluation. By integrating expertise in machine learning, software engineering, and human-computer interaction, we aim to build robust, user-aware code agents that balance performance, safety, and usability.

We envision advancing trustworthy agentic AI by developing LLM-based code assistants that safely and autonomously extend and maintain complex software systems. Grounding our approach in deliberative planning and alignment, we are researching agents that generate secure, explainable code at the repository level, driving a new generation of plan-grounded, verifiably safe agentic AI.

Simplifying and clarifying the assembly code for core operations enabled automated optimization and verification.

Ablation study clarifies trade-offs between accuracy and efficiency when using low-rank adaptation (LoRA) to fine-tune AI models.

By learning the idiosyncrasies of accumulated layers of legacy systems, AI agents can preserve institutional knowledge and provide a unified interface to a range of services.

Agentic vision–language models are increasingly trained to 'think with images' by calling image operations. However, we show that high final-answer accuracy often hides unfaithful visual reasoning: models may invoke tools on irrelevant regions or ignore tool outputs entirely, yet still guess the correct answer. In this work, we first propose a faithfulness evaluation protocol that measures whether intermediate

Generating long, coherent text remains a challenge for large language models (LLMs), as they lack hierarchical planning and structured organization in discourse generation. We introduce Structural Alignment, a novel method that aligns LLMs with human-like discourse structures to enhance long-form text generation. By integrating linguistically grounded discourse frameworks into reinforcement learning, our

Conversational agents have become ubiquitous across application domains, such as, shopping assistants, medical diagnosis, autonomous task planning etc. Users interacting with these agents often fail to understand how to start a conversation or what to ask next to obtain the desired information. To enable seamless and hassle-free user-agent interactions, we introduce Next Question Suggestions (NQS), which
