Human feedback is noisy, heterogeneous, context dependent, and shaped by the process through which data are collected. The postdoctoral researcher will investigate questions involving identifiability, sample complexity, generalization, uncertainty quantification, reward misspecification, and the propagation of estimation error from preference models to learned policies. The work may also develop adaptive methods for collecting human feedback more efficiently. A complementary research direction concerns epistemic control: treating an LLM as a controlled reasoning system rather than as a one-shot response generator. A high-level controller may direct the model to decompose a problem, generate alternative hypotheses, retrieve information, verify evidence, check consistency, request clarification, calibrate confidence, or defer judgment. The project will formulate these choices as a hierarchical decision problem in which an epistemic controller selects reasoning actions that the LLM executes through language generation, structured reasoning, or tool use. The postdoctoral researcher will contribute to theory, algorithms, and empirical evaluation. Possible research outcomes include finite-sample guarantees for preference-based estimators, uncertainty-aware reward modeling, off-policy evaluation methods, adaptive experimental designs, and algorithms for epistemic control under partial observability. Empirical studies may use open-source LLMs and benchmark tasks in reasoning, scientific question answering, code review, tutoring, or decision support. Responsibilities The successful candidate will be expected to: * Develop theoretical and computational methods for RLHF, preference learning, and epistemic control * Establish statistical or algorithmic guarantees where appropriate * Design and implement empirical evaluations using modern machine-learning frameworks and open- source LLMs * Prepare research papers for publication in leading machine-learning, artificial-intelligence, statistics, operations research, or systems venues * Collaborate with faculty, graduate students, and other project researchers * Contribute to the intellectual development of a broader research program on reliable and human-centered AI. ## Related Videos - [Adding knowledge to open-source LLMs](https://www.wearedevelopers.com/videos/1522-adding-knowledge-to-open-source-llms) - [Are Code Reviews Worth It?
