I have taught undergraduates in Oxford in Mathematics and Physics for 5 years. An integral part of the Oxford system is the tutorial system in which students meet their instructors several times a week in pairs for tuition on particular subjects. This normally involves the examination of problem sets or the exposition of the more difficult aspects of the courses. College Lectureships carry pastoral duties and responsibility for undergraduate admission interviews. Notably, Stipendiary Lectureship are senior positions in the associated College and are generally held by postdoctoral scholars. 

Teaching posts I have held at Oxford are listed below:

Stipendiary Lecturer, New College (2012)

Stipendiary Lecturer, St. John's College (2011)

Retained Lecturer, Pembroke College (2008-10)

Non-Stipendiary Lecturer, Hertford College (2008/09)
