Gerhard Visser

Research Scientist in Data Analysis Method Development

My current main area of research is in developing methods for combining different probabilistic estimates, primarily from various geophysics, to produce bigger picture insights and estimates to aid mineral exploration.  Other past work includes development of automated sports prediction systems for industry.  As an undergraduate, I studied computer science and mathematics.  As a postgraduate my research focused on contributing to the theoretical foundations of Bayesian methods.

Throughout my career and studies I have focused on developing the ability to quickly step into new fields and engage with experts from diverse disciplines.  Fields I have worked with include climatology, image analysis, sports science and also geophysics.  I take great interest not only in the mechanics of statistical and data science methods, but also how the are used and abused in practice.

Within Deep Earth Imaging, I am excited to bring my skills to bear on both advanced inverse methods and also to seismic imaging challenges.

Technical skills

  • Deep knowledge of probabilistic method implementation and theory
