Teaching

Han teaches corporate valuation on the School’s MBA, EMBA, MSc in Financial Economics and executive education programmes.

Central to the corporate valuation courses is a focus on how to make good investment decisions. While the courses primarily deal with the underlying mechanics of corporate valuation, they also teach students how to create (and how not to destroy) corporate value.

Han describes his teaching style as ‘encouraging the participants to roll up their sleeves and dive into the numbers and financial reports for critical and creative evaluation and analysis.’ Conducting valuation analysis is necessary but not sufficient in Han’s classes: all students are expected to be able to justify and defend their analysis. He regularly brings insights and experience from the corporate world into the classroom with presentations from visiting expert practitioners.

Han teaches valuation on the following programmes:

  • MBA
  • MSc in Financial Economics
  • EMBA
  • Diploma in Financial Strategy
