What I'm looking for

I'm seeking remote roles in AI training, LLM evaluation, RLHF data, and STEM/biology expert annotation.

At Mercor, I evaluate LLM responses against rubrics for accuracy, relevance, clarity, and safety. I write evidence-based justifications, compare responses to produce preference data, and flag policy violations or unsafe content.

At the University of Pittsburgh, I taught and graded Ecology labs using standardized rubrics. I also led recitations and coordinated undergraduate TAs for a Foundations of Biology 2 course.

My research at the University of Pittsburgh examined duckweed tolerance to heavy metals and freshwater bacteria tolerance to road salt. I analyzed data with linear and mixed models in R and performed DNA extraction, PCR, gel electrophoresis, and SNAP genotyping.

My environmental science and toxicology work includes an M.Sc. thesis on antifouling paint toxicity in microalgae, environmental compliance work in Nigeria, and seven peer-reviewed publications. I also review scientific manuscripts for methodological soundness, factual accuracy, and clarity.
