- Porsgrunn Norway
I did my undergraduate studies in electronics and my MSc in Mathematics. My PhD was in Chemical engineering with focus on granular materials. My education along with years of industrial R&D have given me an expertise base which spans over many different fields of science and engineering. Through my career I have applied my skills in subjects which span from fluid mechanics to real-time measurement systems and as diverse as people management and foundation of science. My broad experience has given me the flexibility to work in many different environments, from academia to factory floor. I consider myself an interdisciplinary scientist who enjoys working with experts from different fields of science and engineering. I know what it takes to create new knowledge, transfer the knowledge to other people and materialize it in form of new technology.
In the past years I have been working on mathematical statistics. Before that my study was focused on symmetry, differential geometry, Lie theory and their application to theory of ordinary differential equations.
I am presently interested on probabilistic models for internal turbulent flow. I have also worked on modelling of motion of particles in viscous fluids and flow through porous media. In my PhD, I developed a mathematical theory for mixing of granular materials.
I have worked on design and implementation of measurement systems. My strength is in design of model-based measurement systems. At present I am working on characterization of Photoluminescence images of multi-crystalline Silicon wafers. My recent work was on development of THz imaging of Si3N4 coating. In recent years I have also contributed in development of two major technologies; fast NIR based in-line crack detection for multi-crystalline Silicon wafers and in-line mass flow measurement for gas-particle systems.
Samples of some of my contributions, which are presently in use in industry.
I am working on topics in probability theory and pattern recognition. I am also teaching part time in several subjects. As a lecturer I am teaching topics in classical physics, physical chemistry and statistics.
My main objective was to publish several years of my research in different fields. My work is organized under categories of mathematical sciences and engineering (for more details check my HiT page). During this period I also work as substitute lecturer in undergraduate physics courses at the college.
My activities during my employment can be divided into following categories (my roles):
During my employment I worked on many research projects related to handling of granular materials. Some of the most important projects were:
During my studies at University of Surrey I was employed at HiT as research fellow where I received a scholarship from the Norwegian research council for 3 years.
Applied research with focus on handling of particulate materials.
My work can be divided into two parts:
Thesis title: A Mathematical Theory for Mixing of Particulate Materials
Supervisors: Ugur Tüzün, Sunil de Silva, Gisle Enstad
The objective of my PhD work was to develop a new theoretical framework, founded on the probability theory, for characterization of particulate materials with application to process of mixing.
Thesis title: On Classification of String- and Space-like Homogeneous Submanifolds in Bianchi Cosmological Models.
In this work I gave a complete classification of certain Lie subgroups important in String theory.
