About

I am an associate professor at the Department of Economics, University of California San Diego. I was born in Montréal (paternal side is Japanese and maternal side is French Canadian) and speak English, French, and Japanese.

My research

I am a mathematical economist with strong interests in applications. My research ranges from general equilibrium with incomplete markets to power law, finance, macro, numerical analysis, and (recently) epidemiology by topics, and from theoretical to numerical and empirical by methods. I have published papers in journals such as Journal of Political Economy, Journal of Economic Theory, Review of Financial Studies, Journal of Financial Economics, Journal of Monetary Economics, Quantitative Economics, American Mathematical Monthly, SIAM Journal on Numerical Analysis, and Physical Review E, among others. I am also a medical doctor (anesthesiologist) and an associate editor at Economic Theory and Journal of Mathematical Economics. Please see my research page for more details.

My philosophy

I find it beautiful when regularity and complexity come together. Some corollaries of this statement are:

  • I like mathematics,
  • I like power law behavior,
  • My favorite composer is J. S. Bach,
  • My favorite artist is M. C. Escher,
  • I like short, simple papers that are to the point.

I also like programming, chess, and tennis, although I am not particularly good at those.
