My research interests include mathematics teacher learning and student mathematical thinking. I earned my Ph. D and Master’s degree in mathematics education from Western Michigan University. I hold another Master’s degree in Social Statistics from the University of Nairobi and Bachelor of Science degree in education from Kenyatta University.

**Bellringers as a tool for addressing pedagogy and mathematical content with pre-service teachers: **Using data collected in a mathematics methods class where we developed a rubric that guided preservice teachers in preparing and implementing bellringers, I explored how the bellringers support preservice teachers’ development of mathematics content and pedagogical knowledge. 2014- 2018

**Elementary Preservice teacher’s perceptions of a number concepts course:** I developed an interview protocol and interviewed elementary preservice teachers taking the Math 1500: *Number Concepts for Elementary/Middle School Teachers* course. I analyzed the data to identify themes in these students’ perceptions of their experiences in the course. Findings of the study could be used to improve the course for future preservice teachers. Presented a poster on the findings at PME-NA 2016. 2014-2016

**Teachers goals, orientation and resources related to use of student thinking:** I was involved in the development of scenarios used to interview teachers to elicit their responses to student mathematical thinking and was part of the team that coded and analyzed the interviews. 2014-2018

**Mathematical Point:** I was involved in designing activities that could be used to support pre-service teachers in identifying the mathematical ideas underlying student thinking. The card sort and matching activity developed in 2014 have been used in a secondary methods course and in professional development for practicing teachers. The card sort was further refined and used with the 2015 secondary mathematics methods class. 2014-2015

**Teachers’ Perceptions of “use” of student thinking: **I was involved in interviewing teachers using a card sort technique about their perceptions of use of student thinking. We later analysed the videos using a framework on productive use of student thinking, to identify where teachers were at in relation to how they view productive use of student thinking. 2014-2015

**Attributes of student mathematical thinking that is worth building on:** I was involved in developing codes and writing the code book used to code attributes of instances of student thinking that are worth building on. I was part of the team that coded and analysed attributes of student mathematical thinking in eleven classroom videos.
