I am an Applied Scientist at Amazon.com, based in Seattle, WA (US). My general research interest is in applied mathematics, machine learning and statistics. During my PhD and Post-doc, I combined neural models and data analysis to help understand the neural basis chemical sensing. I also had a chance to be a Collaboratory fellow at UCLA, where I had the chance to a Unix workshop and create the Machine Learning with Python. I started on Amazon in 2018 after my postdoc, working in Natural Language Processing in Alexa. Today I am part of Econ Technology, working on various problems involving economics, machine learning and reinforcement learning.
