🚀 Exciting News (March 2025): I'm co-teaching a course on 📊 LLM Evaluations in May! This hands-on course for AI practitioners will feature interactive lectures and real homework assignments to help you consistently improve any AI application.

About Me

I'm Shreya Shankar, a fourth-year PhD student at UC Berkeley in the EECS department. I'm advised by Dr. Aditya Parameswaran and supported by the NDSEG Fellowship. Go Bears! 🐻

Prior to my PhD, I worked as an ML engineer in industry. I completed my BS and MS in computer science at Stanford. Go Trees! 🌲

🔬 Research Interests

I build agentic systems to help people work with data. I am also interested in no-code and low-code data tools, enabling people of all technical backgrounds to use AI for complex tasks. I am fortunate that several of my research projects have been deployed in production at major tech companies and startups.

📊 LLM-Powered Data Processing

Building reliable systems and interfaces for LLM applications. Recent work: DocETL for document processing, declarative prompt engineering, and reactive LLM pipelines.

👥 Human-AI Interaction

Creating intuitive interfaces for AI systems. Recent work on aligning LLM evaluators with human preferences and studying how humans interact with AI systems.

🛡️ Data Quality & Validation

Developing tools for reliable AI pipelines. Latest work: SPADE for LLM data quality, automatic data validation for ML, and SCIPE for debugging LLM chains.

MLOps & Monitoring

Designing systems for machine learning in production. Key papers on operationalizing ML and ML observability.

📝 Bio (for speaking engagements, etc.)

Shreya Shankar is a PhD student in computer science at UC Berkeley, working on data management for machine learning and AI. Her research creates practical tools and frameworks that help people build reliable ML systems, with recent work on declarative interfaces and optimization for complex unstructured data analysis.

Shreya is advised by Dr. Aditya Parameswaran. Her work appears in top data management and HCI venues like SIGMOD, VLDB, CIDR, CSCW and UIST, and she co-organizes the DEEM workshop at SIGMOD. She is supported by the NDSEG Fellowship. Prior to Berkeley, she worked as an ML engineer after completing her B.S. in computer science at Stanford University. In her free time, she enjoys roasting coffee and is actively trying to reduce her Twitter usage.

👨‍🏫 Mentorship

I am fortunate to work with many talented students at UC Berkeley. Below is a list of students I am currently mentoring or have mentored for a year or more.

Current Students

Reya Vir (UC Berkeley undergraduate) - Built on a benchmark for synthesizing data quality constraints for LLM applications. (Long) Paper to appear at NAACL 2025! 🎉
Quentin Romero Lauro (University of Pittsburgh undergraduate, REU at UC Berkeley) - Developing interfaces for iterating on retrieval-augmented generation (RAG) architectures for LLM applications. Paper in progress.
Ankush Garg (UC Berkeley master's student) - Building SCIPE, a debugging tool for complex chains and graphs of LLM calls. Deployed SCIPE with LangChain! 🎉
Rachel Lin (UC Berkeley master's student) - Developing interfaces for iterative dataset search with LLMs; co-mentored with Madelon Hulsebos (former postdoc at UC Berkeley, now faculty at CWI).

Past Students

Parth Asawa (former UC Berkeley undergraduate) - Worked on data quality constraints for LLM applications and declarative LLM workflows. Now pursuing a PhD at UC Berkeley.
