Nzubechukwu Ohalete (Nzube)

Part-Time Assistant Professor of Data Science & Analytics at Kennesaw State University. I study when AI-generated data can be trusted, with a focus on LLM agents, synthetic respondents, demographic fidelity, and data integrity.

About

AI systems are increasingly used to generate synthetic data, automate data collection, and stand in for human respondents. My research asks when those outputs are valid, representative, and trustworthy. I build LLM agents for structured data collection, evaluate memory and statefulness, audit synthetic populations against real-world benchmarks, and study how AI-generated submissions can be identified when automation threatens data integrity.

My work sits at the intersection of trustworthy AI, synthetic data generation, survey methodology, and algorithmic bias. Alongside my academic research, I have partnered with Delta Air Lines, Blue Cross Blue Shield of Tennessee, Atlanticus, and Southern Company on applied machine learning and analytics problems in transportation, healthcare, finance, and energy.

Research

Study 1

Autonomous LLM Survey Agents

I developed a locally deployed LLM agent that combines browser automation, DOM parsing, COSTAR-A prompting, layered response matching, and validation-error correction to complete multi-format Qualtrics surveys without human intervention.

Llama 3.1-8B · 8 question types · 100% completion across 3 surveys
Study 2

Memory Architectures for Stateful LLMs

I compared no memory, rolling summarization, structured JSON injection, and retrieval-augmented generation across surveys of 10 to 100 questions, measuring internal consistency, token cost, and completion time.

Study 3

Demographic Fidelity of Synthetic Populations

I audited 10,138 synthetic personas from ten contemporary models across the Claude, GPT-5, GPT-OSS, Llama, and Qwen families against U.S. Census benchmarks under batch and incremental generation.

Research agenda: My next projects focus on diversity-preserving and calibrated synthetic-data generation, longitudinal and cross-national auditing of model outputs, and detection methods that rely on behavioral signatures rather than traditional consistency checks. The broader goal is to make AI-generated data auditable enough that researchers can defend when it should, and should not, substitute for human data.
