Anyone can learn anything.


Hello! I am Issac Lee who is a PhD candidate of Statistics & Actuarial Science at the University of Iowa. My beloved academic supervisor is N.D. Shyamalkumar .

I am generally interested in many machine learning techniques which can be applied in actuarial science field. More specifically, here are some lists of topics which graped my attention thesedays:


  • Pay-How-You-Drive insurance telematics data
  • Replacing nested monte carlo simulation in insurance product valuation process.
  • Making compression portfoilo of insurance products


  • MS in Actuarial Science

    Sungkyunkwan University, 2014

  • BS in Statistics & Industrial Engineering

    Sungkyunkwan University, 2012
