I am Kshitij Ambilduke, a second-year master’s student at the MVA program, ENS Paris-Saclay. My research interests broadly surround Natural Language Processing (NLP) and I am particularly excited about extensions of NLP towards other modalities like speech and vision. I recently worked on investigating gains from using complementary multimodal data over unimodal counterparts in the context of a video-game corpus under the supervision of **Dr. Djamé Seddah** at the ALMAnaCH team, INRIA-Paris.
Before my master's, I worked on extending LLMs to speech as a Research Assistant under the guidance of **Prof. André F. T. Martins** and **Prof. Bruno Martins** at the SARDINE lab, Lisbon.
I completed my bachelor’s in Electronics and Communication from Visvesvaraya National Institute of Technology (VNIT), India. I did my bachelor's thesis with Dr. Anamika Singh where I worked on image captioning. During my pre-final year summer, I worked on interpretable Visual Question Answering under the supervision of Prof. André F. T. Martins and Prof. Bruno Martins.
I was also fortunate to be a part of IvLabs, the AI and Robotics lab of VNIT, where I developed most of my research interests thanks to the oversight of **Prof. Shital Chiddarwar**
