Professor Michael Kosch

Professor

Research Interests

Background

I am an experimental space scientist with a background in electronic engineering. I was born and raised in South Africa and have subsequently worked in many countries and continents, including Antarctica, Australia, Germany, Japan, Norway, South Africa, USA and the UK.

Research

My primary research activity is in the high-altitude (above 80 km altitude) polar atmosphere and near-Earth space environment, mainly using high-power radar as well as bespoke night-vision optical systems. I study the magnetosphere-ionosphere coupling (e.g. Joule heating, current flows and neutral winds), unusual auroral phenomena (e.g. super-fast auroral waves, black aurora), mesospheric dusty plasma (e.g. polar mesospheric radar echoes), atmospheric contraction (e.g. climate change), and space weather effects (e.g. ozone destruction). In addition, I use the upper-atmosphere as a free laboratory to perform active experiments to study fundamental wave-particle interactions and resonances in space and dusty plasmas using high power radiowave facilities located in Alaska, Norway and Russia. This includes experiments which artificially generate auroras.
