Research presentation

Poster

• I was invited to present our work, "QATCH: Benchmarking SQL-Centric Tasks with Table Representation Learning Models on Your Data," at the Gray Systems Lab at Microsoft. This work was published at NeurIPS, a CORE A*-ranked conference recognized as one of the most prestigious venues in machine learning. (2023)
• I had the opportunity to spend three months as a Research Scientist Intern at Megagon Labs in California, where I developed a framework for automatically evaluating retrieval-augmented generation (RAG) systems across different input modalities. This work culminated in a paper published at a CORE A*-ranked conference, "CypherBench: Towards Precise Retrieval over Full-Scale Modern Knowledge Graphs in the LLM Era." (2024)
• I was honored to be selected as one of only 36 participants for the invite-only workshop "LLMs Meet Data Processing" at the University of California, Berkeley. The workshop brought together researchers from leading institutions, including Berkeley and Stanford, as well as representatives from prominent companies such as Google and Databricks. (2025)
• I was selected to participate in the SAP Business AI Research Retreat, an invitation-only event that brings together leading researchers to discuss SAP's Business AI agenda. My invitation reflects external recognition of the quality and impact of my research, as well as its strategic relevance for collaboration with SAP. (2025)
• This award is comparable to a best paper award at a conference and grants the authors the opportunity to present their work at an A*-ranked conference (NeurIPS, ICLR, or ICML) through the journal-to-conference track. The paper "Think2SQL: Blueprinting Reward Density and Advantage Scaling for Effective Text-to-SQL Reasoning" was accepted for presentation at NeurIPS 2026. (2026)
