# Kristin Liu

**Headline:** Professional profile
**Location:** St. Louis, MO, USA

## About

Kristin Liu is an AI and machine learning engineer specializing in multi-agent systems, including systems built with LangGraph. She designs and evaluates AI platforms with a focus on reliable, scientifically oriented agent workflows. Kristin built a multi-agent AI platform that automates the full scientific research cycle, from idea generation and literature search through code writing, execution, and result generation. Her strengths include system design, platform evaluation, and the practical controls needed to make LLM-agent systems dependable. She designs constraints and tool limitations to reduce hallucinations and prevent infinite loops, and she implements validation across the agent lifecycle. Her approach includes pre-execution checks, agent self-debugging, post-execution logging, and human audit mechanisms that support reproducibility and oversight. Kristin also maintains ongoing collaboration with her university on research projects after graduation. Her work reflects a sustained interest in multi-agent systems and model speed, alongside careful attention to reliability, traceability, and scientific workflow automation.
