TextTextQuestion AnsweringQuestion Answering

Conducted applied research where complex multi-variable problem statements were developed, documented, and verified for correctness. This work closely maps to AI evaluation by requiring structured reasoning chains, identification of inaccuracies, and ensuring factual correctness in technical responses. Produced well-documented methodology and findings that function like curated training/evaluation content for physics- and engineering-style question design. • Designed multi-step, non-trivial problem statements requiring reasoning pathways. • Compiled detailed technical reports emphasizing verified conclusions. • Applied thermodynamics and materials science concepts to validate engineering challenges. • Translated research challenges into clear, problem-ready documentation.

Mathematics Tutor — Young Minds Tutors (Structured reasoning problem design & correctness feedback)

TextText

Tutored engineering mathematics by breaking down calculus and linear algebra problems into clear, verifiable reasoning steps. Developed practice problems that required multi-step reasoning, analogous to generating and validating question content for AI problem design. Demonstrated the ability to detect where reasoning goes wrong and provide corrected explanations. • Created and administered multi-step practice problems for student understanding. • Explained complex calculus/linear algebra using structured reasoning chains. • Identified incorrect reasoning and corrected student solutions. • Trained learners to follow verifiable, step-by-step problem-solving logic.
