About me

I am an Applied ML Scientist at Amazon Alexa, working on NLP and Question Answering. Prior to that in my PhD I worked on ML for rendering and analysis of scientific data. I focused on self-supervised methods and had occasional encounters with generative image models, style transfer and reinforcement learning. Additionally, I have solid software development skills and 3+ years of industry experience.
