## Summary  
Clarisse De Souza is a Brazilian computer scientist and writer best known for developing the theory of semiotic engineering. She specializes in human-computer interaction and human-centered computing, with a career spanning decades at the Pontifical Catholic University of Rio de Janeiro. Her work bridges computational design and semiotics, influencing how systems communicate with users.

## Biography  
- **Born**: 1957 (location not specified)  
- **Nationality**: Brazilian  
- **Education**: Pontifical Catholic University of Rio de Janeiro  
- **Known for**: Developing semiotic engineering theory  
- **Employer(s)**: Pontifical Catholic University of Rio de Janeiro (professor since 1988)  
- **Field(s)**: Computer science, human-computer interaction, semiotic engineering  

## Contributions  
Clarisse De Souza pioneered semiotic engineering, a framework that applies semiotics—the study of signs and symbols—to human-computer interaction (HCI). Her theory treats software interfaces as communicative artifacts, emphasizing how designers "speak" to users through systems. She has authored influential publications, including *The Semiotic Engineering of Human-Computer Interaction* (2005), which formalized the approach. Her work has shaped HCI research, particularly in Brazil, where she mentored generations of scholars. De Souza’s contributions are recognized by her 2013 induction into the CHI Academy, honoring her impact on the field.  

## FAQs  
### Q: What is semiotic engineering?  
A: Semiotic engineering is Clarisse De Souza’s theory that frames HCI as a communication process between designers and users, using interfaces as "messages" conveying design intent.  

### Q: Where does Clarisse De Souza work?  
A: She has been a professor at the Pontifical Catholic University of Rio de Janeiro since 1988, contributing to its computer science and HCI research.  

### Q: What awards has she received?  
A: In 2013, she was inducted into the CHI Academy, a prestigious honor recognizing her contributions to human-computer interaction.  

## Why They Matter  
Clarisse De Souza’s semiotic engineering theory redefined how researchers analyze and design interactive systems, emphasizing metacommunication in technology. Her work provided tools to critique and improve user experiences, influencing academic and industry practices. By integrating semiotics into HCI, she expanded the discipline’s theoretical foundations, particularly in Latin America. Without her contributions, the field might lack critical frameworks for understanding designer-user dialogue.  

## Notable For  
- Developing semiotic engineering, a foundational HCI theory.  
- Induction into the CHI Academy (2013).  
- Decades of mentorship at Pontifical Catholic University of Rio de Janeiro.  
- Authoring *The Semiotic Engineering of Human-Computer Interaction* (2005).  

## Body  
### Academic Background  
- Educated at Pontifical Catholic University of Rio de Janeiro.  

### Career
