Personal profile

Research interests

Permafrost: My main research interest is the rock slope stability in permafrost areas, such as high mountain ranges. The stability of a rock mass is mainly determined by joints in the rock. If these joints are frozen together, even vertical rock slopes can be very stable. However, as temperatures increase the ice in rock joints starts to become weaker and eventually it melts. This can lead to large rock falls that endanger infrastructure and may even cost lives. I measure the shear strength of ice filled rock joints in the lab to be able to predict the behavior of rock slopes in a warming climate.

Roman concrete: Recently I developed a research interest in re-creating Roman concrete. This type of lime-based concrete is known to have extremely high durability with buildings still standing after 2000 years. Its production has a lower carbon footprint than the production of Portland Cement, which makes it interesting as a new building material. I experiment with different types of lime and different sources of silica, such as natural volcanic ash and pulverized fuel ash, to improve the strength of the material.

Approach to teaching

I have come to civil engineering from a background in geology, which gives me a view of the subject from a different angle. I try to pass this on to the student to broaden their horizon and to prepare them for their careers where they will work with professionals from many different backgrounds.

I always think it is extremely important for students to understand the basic principles of a subject and be then able to apply these principles to problems given to them. To achieve this I give students a hands-on approach with lab classes, field days and exercises. I also use specialised software for my teaching.

During my classes I like to engage my students in discussions where they can apply the theory taught in class, explore different options and practice critical thinking.

I expect my students to engage in the subject, read the background material (relevant chapters from the reading list) each week and attempt their exercises every week. I am always open for questions from students to make sure they receive all the support they need.

I enjoy supervising final year projects, where I offer a wide range of topics, ranging from numerical analysis of tunnel and rock slope stability to recreating Roman concrete and plant fibre or bamboo reinforced concrete.

Scholarly biography

I studied Geology (5-year course) at the University of Munich from 1984-1989. After that, I continued my studies with a PhD in Geophysics from which I graduated in 1994. After working for consultancy companies, carrying out geophysical measurements, I was employed by the Geological Survey of Bavaria from 1997-1999. In 1999 I moved to Manchester, where I worked until 2000 as a research fellow with a geotechnical centrifuge. This post was followed by two more research posts at the Imperial College in London (2001) and the University of Dundee (2001-2006. In 2006 I was appointed Senior Lecturer at the University of Brighton. Here I have taught a range of subjects, such as concrete technology, mechanics of materials, soil mechanics, engineering geology and rock mechanics.
