About Pujari Keerthika

I'm Keerthika (Pujari Keerthika), originally from Andhra Pradesh, pursuing a B.Tech in Computer Science at SRM University and a BS in Data Science and Applications at IIT Madras. I've worked as a research intern at IITM. My research spans intent-based networking, computational chemistry, 3D scene reconstruction using NeRF and transformers, and EMG-based gesture recognition.

I'm planning to pursue a PhD in computer vision, NLP, or ML for scientific applications. I speak five languages and am currently learning French.
