I am a PhD student in Computer Science at UC San Diego jointly advised by Professor Julian McAuley and Professor Shlomo Dubnov. I am currently working on machine learning for audio signal processing and also exploring security aspects of neural network models. I received my undergraduate (B. Tech) degree in Computer Science from Indian Institute of Technology (IIT), Roorkee in 2017. Besides research, I co-lead the technical team at Blue Water where we work on developing voyage optimization and weather routing solutions for maritime companies.
