Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

Scientist
A scientist in a broad sense is one engaging in a systematic activity to acquire knowledge. In a more restricted sense, a scientist is an individual who uses the scientific method. The person may be an expert in one or more areas of science. This article focuses on the more restricted use of the word...

Research and patents

His research focuses on the reaction dynamics of small molecules and how they influence the composition of the interstellar medium. He recreates the conditions of outer space in the laboratory using special devices called ion 'traps' or 'storage rings'. In these devices, he is able to briefly store and measure the properties of small amounts of material, as little as a few hundred atoms or molecules-worth, under the extreme conditions of interstellar space (especially very low temperatures and low densities). Some of his research has focused on the puzzle of how complex molecules are formed in outer space.
