Reasoning Opens up New Retrieval Frontiers

Orion is a 5th year PhD student at Johns Hopkins University affiliated with the Center for Speech and Language Processing and advised by Benjamin Van Durme and Dawn Lawrie. His work primarily focuses on measuring and improving the capabilities of information retrieval models and retrieval-augmented generation with language models. His work is supported by grants from the National Science Foundation and has won paper awards at the Conference on Language Models (CoLM) and the European Conference on Information Retrieval (ECIR).

Hamel is a machine learning engineer with over 20 years of experience. He has worked with innovative companies such as Airbnb and GitHub, which included early LLM research used by OpenAI, for code understanding. He has also led and contributed to numerous popular open-source machine-learning tools. Hamel is currently an independent consultant helping companies build AI products.

Shreya is an experienced ML Engineer who is currently a PhD candidate in computer science at UC Berkeley, where she builds systems that help people use AI to work with data effectively. Her research focuses on developing practical tools and frameworks for building reliable ML systems, with recent groundbreaking work on LLM evaluation and data quality. She has published influential papers on evaluating and aligning LLM systems, including "Who Validates the Validators?" which explores how to systematically align LLM evaluations with human preferences.

Prior to her PhD, Shreya worked as an ML engineer in industry and completed her BS and MS in computer science at Stanford. Her work appears in top data management and HCI venues including SIGMOD, VLDB, and UIST. She is currently supported by the
