About
I'm a Principal AI Research Scientist at Autodesk AI Lab, where I focus on developing large foundation models for the 3D world, particularly in the architecture, engineering, and construction (AEC) domain. Previously, I was an Applied Scientist at AWS AI Labs working on Amazon Q Developer (formerly CodeWhisperer) and Bedrock large language modeling services.
I received my Ph.D. in Computer Science from the University of Minnesota, where I worked on deep generative models, approximate inference, and probabilistic models with applications to text and image data.

Selected Publications
Multi-task pretraining with structured knowledge for text-to-SQL generation
R. Giaquinto, et al. | ACL 2023

We generate SQL code from natural language by using and encoder-decoder trained on a large pretraining dataset with multitask learning strategy. Our method leads to state-of-the-art performance with significant improvements on the Spider and CoSQL benchmarks.
Multi-lingual evaluation of code generation models
B. Athiwaratkun, et al. | ICLR 2023

We introduce MBXP, Multilingual HumanEval, and MathQA-X: new benchmarks for evaluating code generation models across over 10 programming languages. Our study reveals surprising capabilities in language models, including out-of-domain language generalization and zero-shot translation abilities, while demonstrating the advantages of multi-lingual models over mono-lingual approaches.
Gradient boosted normalizing flows
R. Giaquinto and A. Banerjee | NeurIPS 2020

We introduce Gradient Boosted Normalizing Flows (GBNF) to improve normalizing flows through gradient boosting rather than deeper architectures. GBNFs create a mixture model that grows in flexibility as components are added, offering better performance than traditional flows while maintaining simpler transformations.
