I am a Senior Manager of AI and a Principal Data Scientist at LexisNexis (a legal AI leader). My team works in the areas of Natural Language Processing (NLP) and Generative AI with Large Language Models (LLMs). Select products: Lexis+ AI (the most powerful personalized AI Assistant for legal professionals; now in its third generation as Protege), Lexis Connect (AI for corporate legal; press release), Lexis Search Advantage (AI for law firms). To power these products, we train, finetune, and deploy several transformer-based small and large language models in production; both closed and open source.


Before Lexis, as a Manager and Lead Principal Scientist, I led the Artificial Intelligence Group for the Carol Data and AI platform at TOTVS Labs USA (a “startup” lab focusing on Computer Vision, NLP, and ERP/Tabular Analytics). My team was responsible for the innovation as well as the implementation of features for products such as Carol ClockIn (facial recognition for employee clockin), Carol Assistant (AI for conversational experience), and Deep Audit (insurance claims management with neural attention models). These products have a market leading presence in the Latin Americas. 


Prior to TOTVS, I was a Machine Learning Tech Lead and Lead Principal Scientist at ABB (AI for power, robotics, and automation sectors). My innovations, projects, and technical leadership significantly contributed to and influenced the formation of ABB Ability


My areas of work and interest in AI include NLP, Large Language Models (LLMs), Reinforcement Learning, and Computer Vision
