I am a theorist interested in macroeconomic theory and macroeconomic dynamics in their relations to mathematics, probability theory and mathematical statistics. My goal as a theorist is to improve the standard of living for all human beings through a better understanding of macroeconomics that consists of infinitely many various heterogeneous agents as its micro-foundation. My research encompasses mathematical economics, probability theory, mathematical statistics in their relations to macroeconomics of sticky prices, monetary policy, asset pricing, economic growth, business cycles, investment, income and wealth inequality, and any distributional dynamics. Overall, both my current and future research agenda revolve around my goal as a theorist to benefit humanity through a better understanding of macroeconomics and its micro-foundation in their relations to mathematics, laws of the universe, and eventually, the truth.
