Vinícius Ferraz
Data and A.I. Products Specialist
Researcher in Machine Learning applied to economics and business problems
I am a researcher specializing in computational and experimental economics, working at the intersection between economics and computer science. My academic contributions primarily focus on developing and applying computational models to address complex business and economic challenges.
Parallel to my academic pursuits, I hold the position of Chief Data and AI Officer at ILI.DIGITAL AG, leading the Data and AI products team. My professional path has been marked by roles in data science, digital strategy, and product development, with former positions at Ernst & Young (EY), Trivago, and Deutsche Telekom.
This website is designed to collect my scholarly work and public engagements, including scientific papers, code repositories, articles, and more.
Research Interests
My research interests are focused on the computational modeling of economics and business problems. This includes studies of decision behavior, economic experiments, game theory, agent-based simulation models, machine learning, and Generative AI.

Work in Progress
Here you can find an overview of project I am currently working on
A Large Scale Prediction of Behavior in Completely Mixed Games: A Machine-Learning-based approach
with R. Nagel
Description: This project involves a machine learning analysis of 2x2 game frameworks, using data from multiple experimental studies. The approach employs a feature-engineered dataset to glean insights into the anatomy of these game scenarios, as reported in existing literature. The objective is to uncover the factors that significantly impact observed behavior.
Exploring Gender Differences in Interpreting Feedback Through LLM-Driven Simulations in Professional Settings
Description: This research project analyzes gender differences in the interpretation of feedback and confidence levels within a business environment. We use large language models (LLMs) as simulated agents to mimic interactions in a company setting, aiming to understand how gender influences feedback reception and self-assurance in professional contexts.
