Chris Gaffney is Head of Archaeological & Forensic Sciences at the University of Bradford. His doctoral research was conducted under Arnold Aspinall at Bradford on the Schlumberger resistance array, investigating its suitability for archaeological surveys. On leaving academia he worked in the commercial sector, including 18 years at GSB Prospection (in Bradford), which he led together with John Gater. And yes, he did appear in Time Team!

Chrys Harris


since 15 Sep 2017 , re-elected 31 Aug 2019

Chrys is currently a Director of Magnitude Surveys Ltd, a social enterprise and specialist archaeological geophysics contractor to the community, public outreach and commercial sectors. Her passion for archaeological geophysics developed during her BA degree (Anthropology – emphasis in Archaeology) at Minnesota State University Moorhead in the United States. This lead her to pursue the specialised MSc in Archaeological Prospection at the University of Bradford in the United Kingdom.

Armin Schmidt

Honorary Secretary

since 15 Sep 2017 , re-elected 31 Aug 2019

Although my earliest aspirations were to become an 'inventor' (a suitably broad job description), my fascination was always with history and ancient civilisations. However, in the end the natural sciences got the better of me and in 1982 I began to study Physics at the University of Technology Munich (Technische Universität München). One of the key events for me during that time was a seminar given by Helmut Becker in which he described his wonderful results from archaeological prospection using Caesium magnetometers. I was hooked.

Christophe Benech

Conference Secretary

since 31 Aug 2019

Conference Vice-Secretary

since 31 Aug 2017

James is an archaeological geophysicist working in the academic sector, with specialisms in the use of legacy data; 4D time-lapse assessments; the application of electromagnetic induction for the assessment of archaeological sites within challenging environments and variable geological backgrounds; induced polarisation, upland archaeology; conflict archaeology and archaeological deposits threatened by coastal erosion.

Kayt Armstrong

Natalie Pickartz

Ordinary Member

since 13 Oct 2019

Natalie Pickartz is currently finishing her PhD in the working group 'Applied Geophysics' at the Institute of Geosciences at Kiel University, Germany. She developed her passion for archaeology already as a child. In 2008 she began to assist in archaeological and geophysical fieldwork before starting her studies. She executed her Bachelor and Master thesis at the University of Cologne (Germany) on geophysical measurements at archaeological sites. With her Bachelor thesis she focused on electrical resistivity tomography of a roman villa rustica.

Michal Pisz

Ordinary Member

since 13 Oct 2019

I am currently a PhD Student at the Departament of Applied Hydrogeology and Geophysics at Faculty of Geology, University of Warsaw. My adventure with archaeological prospection and archaeo-geophysics has begun back in 2009, during my BA degree (Archaeology). Since then my research activity was always related to archaeological prospection, mostly on Roman sites. This passion helped me to conduct my first big research project in the hinterland of Tibiscum Roman fort in Western Romania.

Joanna Szarkowska

Ordinary Member

since 13 Oct 2019

Joanna is a geoarchaeologist based in Warsaw, Poland. She graduated with BA in Roman Archaeology in 2011 and MA in Baltic Archaeology in 2014 from the University of Warsaw. During her time at the University she became interested in the application of Earth Sciences in Archaeology.

Rob Vernon


since 13 Sep 2003 , re-elected 31 Aug 2019

Rob Vernon was born in Liverpool in 1945. He graduated in 1969 with a BSc (Hons) in geology from London University. Between 1969 and 1993 he held a variety of senior posts as a geologist in the British coal industry (deep mines), where he became familiar with downhole geophysical logging and seismic surveying. After leaving the coal industry, Rob gained an MSc in Archaeological Prospection in 1995, from the Department of Archaeological Sciences, University of Bradford where he continued to conduct part-time research on the geophysical responses produced by British smelting sites.
