About me
I am a Senior Machine Learning Engineer at Google Research mainly working on multimodal LLMs including Gemini and PaLM models, also developed a number of NLP products for Google Cloud. I received a Ph.D. in Computer Science from Georgetown University. I was fortunate to work with my advisor, Prof. Lisa Singh. My research focused on NLP, Language Models, Data Science, and Social Media Mining.
During my PhD student’s life, most of my projects were collaborations with CNN, Washington Post, UMich and MDI on leveraging AI/ML methods for data-centric social concerns such as sentiment analysis, stance detection, force-migration, gun policy, MeToo movement, spam, misinformation and fake news. During summers, I spent some time working at 
Twitter and 
Google.
