Dr. Sascha Reth

Dr. Sascha Reth studied biology at the University of Kaiserslautern. His diploma thesis “Structural estimation of a heterogeneous oak forest (Quercus petraea) with red beech (Fagus sylvatica) under stature and analysis of the chemical heterogeneity of the oak foliage" was finished in 2000. Then he intensified his knowledge of Climate Geography at the University of Cologne, before he started his graduate dissertation at the University of Bayreuth with the topic “Improved estimates of CO2 and N2O flow rates of soils of Central European ecosystems - development of conceptual innovations of soil emission models”.

Furthermore Dr. Reth was responsible for the coordination of scientific research on the lysimeter station at the Helmholtz Zentrum München - German Research Center for Environmental Health, Institute of Soil Ecology. His own research focus was the observation of trace gas emissions in the context of climate change in lysimeters.

Since 2007 Dr. Reth is member of the steering committee of the “International Lysimeter Research Group”.

In 2008, he set up the branch of the UGT GmbH in Freising, Germany. Since 2012 he is Managing Director and Partner of UGT.

Dr. Christian Heerdt is since November 2010 member of the UGT team. In research and development, he is responsible for new product developments. For national and international projects he is working as a project manager and supports the sale in all types of technical questions in measurement technology.

Before joining the UGT team, he was a research assistant at the Technical University of Munich, Germany (TUM ) at the chair of Ecophysiology of Plant and the Chair of Ecoclimatology. He was working on various research projects in the field of environment, climate and atmosphere (inter alia the special research program SFB607 ) developing measurement methods and measurement instrumentation design. Prior to that, he was a research assistant at the Chair of Bioclimatology and Immission Research (Ludwig- Maximilians-University Munich, Germany) with a focus on methods of measuring atmospheric constituents. For his PhD, he developed a method for small-scale ozone monitoring in a beech / spruce mixed stand under doubled ambient free-air ozone exposure.

Dr. Marco Reiche

Dr. Marco Reiche has joined the UGT team in April 2017 as head office manager. He studied aquaculture and limnoecology at Humboldt University Berlin and graduated as agrarian engineer and master of science. Then, he became a microbiologist in the field of aquatic geomicrobiology at the Friedrich-Schiller-University in Jena. His work was focused on the investigation of microbial mineralization processes in an acidic fen, pelagic boundary conditions in an acidic coal mining lake, and the biological formation of iron-rich particles (iron snow) induced by microbial communities.


Dr. Marco Reiche has started his business career as a director of R&D in a company dealing with cooling water treatment technologies in Düsseldorf. Afterwards, he worked as a development engineer in the context of water treatment technologies in a company located in the Black Forest. Before he switched to UGT he was a biological and technical consultant for an investment family office near Frankfurt Main.
