Chairman and Head of Research

In 1981 Aleksander obtained his PhD in seismology from the Silesian University of Technology (Poland), where he worked as an Assistant Professor. In 1985 he took up the position of Head of the Seismology at Anglo American plc in South Africa. In 1991 he was appointed the Managing Director and Head of Research at ISS International Limited (ISSI) and, in 1994, also the Managing Director of ISS Pacific (ISSP). In 2010 he founded the Institute of Mine Seismology in South Africa and Australia. IMS acquired both ISSI and ISSP and Aleksander became its Chairman and Head of Research.

His main areas of expertise are monitoring seismic rock mass response to mining, quantification of seismic sources and near-source ground motion, deterministic and probabilistic seismic hazard assessment in mines, and the application of quantitative seismology to rock mass stability. He is the main author and editor of Seismic Monitoring in Mines, (Chapman and Hall, London, 1997).


Managing Director and Head of Computational Seismology – IMS Australia

Ernest has a PhD in Mathematics from University of Stellenbosch (South Africa), focusing on the study of towers of algebraic function fields. In 2006 he joined ISSI, starting on location problems, using ray-tracing to perform cave-front tracking. He since took over the development of the seismological processing software, developed it as an extensible platform for providing seismological services, and worked on seismic source characterisation.

As part of the Research and Development Programme, he has written kinematic modelling software, worked on seismic source directivity characterisation, and enjoys developing massively parallel codes to solve computationally hard problems.

Since moving to Australia in 2012, Ernest has been working on next-generation seismological processing and visualisation software, and envisages extracting more useful information from seismic data in a routine manner than the classical models allow for, in particular with respect to exploiting continuous data and directivity effects. He is currently looking at short-term hazards and ground-motion hazards.


Director and Head of Applied Seismology – IMS Australia

Dmitriy has a PhD in Physics and Mathematical Science from the Institute of Physics of the Earth (Moscow, Russia). From 2000 until 2009 he worked at the Mining Institute (Perm, Russia) and was involved in regional seismic monitoring, local seismic observations in potash mines and karst caves, and engineering seismology projects. In 2009 he joined ISSI (South Africa), which later became the Institute of Mine Seismology (South Africa, Australia and Canada). He is responsible for seismological services for mines (processing and interpretation of seismicity, investigation of large or damaging seismic events) and is involved in research projects in mine seismology.

Dmitriy is interested in inferring information about seismic sources from seismic signals, the integration of seismic monitoring data with stress modelling, and the assessment of seismic and ground motion hazards associated with planned mining.

Frans has an NDIP in Electrical Engineering (Light Current) from the Central University of Technology (South Africa). In 1999 he started working for ISSI, taking responsibility for installations and maintenance of the seismic systems installed in South Africa. In 2002 he was deployed as Manager of ISSP (Australia). He served in that position until the end of 2007. Upon relocating back to South Africa, he managed the Technical Services departments for both ISSI and ISSP.
In 2011 he moved back to Australia, managing both our Technical Services department and IMS’s local Production Facility from our Huntingfield office.


Director and Head of System Development – IMS Australia

Gareth obtained his MSc in Electronic Engineering from the University of Cape Town (South Africa). He has a background in mixed-signal electronics; instrumentation and control; signal processing; and intelligent systems.
In 2006 he started working at ISSI as System Engineer, Developer before progressing to Manager. His core focus areas in this position were: analogue and digital hardware design; embedded systems and industrial communications; and telemetry. Gareth has led the development of the IMS seismic monitoring system since its inception in 2010.

In 2016 Gareth started his PhD candidature at the University of Tasmania. His research focuses on signal processing techniques, specifically relating to active seismic monitoring.


Director and Head of Finance – IMS Africa

Kobus has a B.Com Hon in Economics from the University of the Orange Free State (South Africa). He has been with ISSI since 1990, first heading the Finance and Administration Department. Since 1994 he has also been responsible for Finance and Administration of ISSP. He fulfils the same role in the Institute of Mine Seismology. His responsibilities include the Finance, HR and Legal aspects of the business.


Business Development Manager – IMS Africa

In 1990 Olaf obtained his MSc in Geophysics from the University of Witwatersrand (South Africa). He then joined the Chamber of Mines Research Organisation (COMRO). During his 16-year career at COMRO (and later CSIR Miningtek) he became involved in a number of geophysics, mining and rock mechanics-related research projects. His primary interest was seismology, developing his expertise in mine seismic monitoring.
Olaf honed his commercial skills during his five years at Snowden Mining Industry Consultants in Johannesburg. In 2011 he joined IMS as the Business Development Manager. His responsibilities include developing IMS’s client base in Africa and providing routine seismological services to customers in Africa.


Director and Head of Seismological Services – IMS Africa

Jacques has an MSc in Applied Physics from the Nelson Mandela Metropolitan University (South Africa). Since joining IMS in 2012, he has been involved in various research projects focusing on assimilation of seismic data with numerical rock-mass modelling. He currently manages Seismological Services in South Africa and is involved in providing routine seismological services to the gold industry.


Director and Head of Seismic Data Processing – IMS Africa
