 My research interests in the area of Psychometrics are centered around three broad topics: 
  • Dimensionality Assessment -- statistical assessment of assumptions underlying psychometric models. 
  • Differential Item Functioning -- study of item/test bias in educational and psychological tests. 
  • Item and Ability Parameter estimation and effect of dimensionality on estimation.
