Entry-level Research Scientist resume example

• Proposed a bounded machine learning study for the team’s research agenda at OpenAI, choosing impactful research problems from an error taxonomy with a senior scientist; independently maintained the experiment plan for a long-running project while the supervisor approved compute and release decisions.
• Within an assigned study reviewed by a senior colleague, developed a machine learning technique for verifier-guided reasoning with a fixed token budget, comparing uniform sampling, uncertainty-based allocation, and a supervised baseline; contamination checks and component ablations isolated the allocation effect from the benefit of simply spending more compute.
• Within an assigned study reviewed by a senior colleague, built high-performance implementations of deep learning algorithms in PyTorch, profiling activation memory and throughput before changing batching and checkpointing; reduced a fixed evaluation run from 11.4 to 8.1 GPU-hours while preserving the same prompts, seeds, and quality checks.
• Within an assigned study reviewed by a senior colleague, collaborated with peers in evaluation and infrastructure to test generalizable ideas at large scale; ran the same baseline across three model sizes and rejected an apparent gain that disappeared on the held-out domain, preventing an unsupported full-scale run.
• Within an assigned study reviewed by a senior colleague, wrote the first-author project report for a verifier-budget study, testing new ideas for allocating extra reasoning steps to uncertain answers; ablations showed that selecting harder examples mattered more than simply generating longer answers, and independent reviewers reproduced the comparison from the run manifest.
• Within an assigned study reviewed by a senior colleague, assessed impacts of AI technology by testing confident errors and abstention in unfamiliar domains; reviewers approved a failure-case appendix and release limitation after benchmark accuracy failed to reduce unsupported answers reliably.
• Within the assigned scope, reproduced a baseline using pinned dependencies and held-out tasks, reported confidence intervals across seeds, and included failed ablations rather than only the strongest run.
• Within the assigned scope, owned a machine-learning ablation using fixed seeds and peer-reviewed assumptions, resolved a confounded baseline and completed a reproducible report of negative results.
• Within the assigned scope, built a high-performance implementation using profiled kernels, reduced evaluation runtime by 28% at equal accuracy and published limitations relevant to the research agenda.

• Reproduced instruction-tuning experiments in a university machine learning lab, preserving dataset splits and three random seeds; found duplicate examples and corrected the comparison before the supervisor approved the report.
• Presented a graduate-lab reproduction with per-domain error tables and uncertainty intervals; a lab mate reran the notebook from a clean environment, exposing a tokenizer mismatch that was corrected before the dissertation comparison was finalized.
• Within the assigned scope, investigated a discrepancy between a published metric and its source records, traced the transformation that changed the population, and corrected the calculation with a reproducible query.
• Within the assigned scope, compared the last successful data refresh with a failed run, separated missing source data from transformation errors, and reran only the affected interval. Kept the original query and corrected result together for review.

• Created a reproducible research project comparing reasoning accuracy and abstention on 1,200 synthetic multi-step tasks; published an internal project report with dataset-generation code, baselines, negative results, and a statement that synthetic-task gains do not establish real-world safety.
• Logged accuracy, generated tokens, and GPU time at three inference budgets on the same held-out tasks; extra compute helped harder reasoning tasks but did not fix confidently wrong answers, supporting a bounded adaptive budget with an explicit abstention rule.
• Generated synthetic source records with duplicates, late arrivals and corrected values; wrote assertions for row counts and key uniqueness, and recorded the expected effect of each case on the reported metric.
• Compared the analytical output with a manually calculated reference table, traced differences to a transformation step, and retained a data dictionary and rerun instructions alongside the corrected query.
• Owned the synthetic-data validation using a manually calculated reference, resolved duplicate-key inflation and completed a notebook that reproduces the corrected totals.

• Published an independent methods note using reproducible queries, explaining the data grain, excluded records and sensitivity of the result to a changed denominator.
