Danilo S. Carvalho, Ph.D. Assistant Professor - Computer Programming / AI / NLP

Vision & Research Focus

My research work deals with understanding and filling the gap between the realm of human though, and in particular human language and the realm of computer machinery, which is the key component the next generation of intelligent systems that will be able to automatically understand and process the meaning of information at scale.
I have been involved with Artificial Intelligence (AI) and Natural Language Processing work for almost a decade, in which this field has seen several big advancements in technology and practical applications, from the generation and organization of massive textual corpora to Neural-based Machine Translation. Now, the application of AI in many areas hangs in the ability to explain the answers it provides, with both the analysis of healthcare information and of the propagation of misinformation on online social media posing as challenging, but necessary testing grounds for the design of explainable AI, wherein lies my current efforts.
