Teaching experience

Current research interests

I am primarily interested in understanding the development and cognitive mechanisms of word reading fluency, focusing on topics such as:

  • rapid serial naming tasks as models of fluency
  • implicit orthographic learning and visual word recognition
  • cognitive skills specifically underlying fluent reading
  • simultaneous cascaded processing of multiple elements in reading words and lists
  • the eye-voice span and other eye-tracking measures as indexes of fluency
  • lexical, sublexical, and practice effects on visual word recognition and lexical access
  • relationships of word reading fluency with decoding and text comprehension

I am also interested in methodological issues including experimental design in behavioral, neuroimaging, and eye-tracking studies, statistical modeling and data analysis, measurement, and psychoeducational assessment, including psychometrics and computerized testing.
