Dr. Stephen J. Payne

Welcome to my web site. This site is currently under construction.

Work

I am currently employed as:

Research Assistant in the Department of Engineering Science at the University of Oxford

College Lecturer at University College, Oxford

Research

I have been working for the Medical Images And Signals (MIAS) IRC under the supervision of Professor Lionel Tarassenko since May 2001. I am working on the following projects (in approximate order of importance!):

Cerebral autoregulation

This is aimed at improving our understanding the physiological causes of autoregulation failure.

Dimensionality reduction and novelty detection

This is aimed at providing improved means of modeling complex multi-dimensional data sets in lower-dimensions.

Detection and determination of underground material (with applications primarily to landmine detection)

This is aimed at using some of the above techniques to distinguish between features found during landmine detection.

Unsteady measurement of entropy in turbomachinery

This is aimed at improving our understanding of the measurement of unsteady entropy at high frequencies.

Teaching

I have been tutoring since October 1997 and have been based at Univ since October 2000, where I teach a wide range of papers and help with pastoral and administrative duties for the 29 students. I currently teach parts of P3, P4, A3, A4 and A5 to first, second and third years at University College and Corpus Christi College.

Personal

I play the piano and the organ, holding the ARCO diploma, and working towards FRCO whilst being the organist at Jesus College. I became a Christian in 1997 and now attend St. Ebbe’s church, where I play the organ and lead Bible studies with international students. I also like reading and watching cricket.
