What is my role within CATALPA?

As a computer scientist in NLP, I work on analysing robustness and explanations of multimodal systems having language as one of the modality.

Why CATALPA?

In CATALPA, I can propose my research to a diverse and interdisciplinary area of expertise which would be helpful for me to provide visionary suggestions and a global perspective of the problem I am trying to solve. Multimodal solutions to NLP is need lots of expertise and visionary road maps that i am confident to get it from CATALPA.
