Research Interests

Dr David Dowling is the Head of Faculty of Science at the Institute of Technology Carlow and is research active in the area of Environmental microbiology/biotechnology.

I was employed as a research scientist at the Max Planck Institute in Cologne, Germany, the University of Geneva Switzerland and the Federal Institute of Biotechnology, Germany, before moving to University College Cork in 1990 as a senior research scientist. I joined IT Carlow in 1996 as a lecturer in biotechnology. My research has been funded by EU, National and Industrial sources and in the last 10 years I have raised almost 2 million euro in research funding at IT Carlow. I was a member of the EU Cost programme management committee (Cost FA849 and FA1103) on Phytotechnolgies and I have experience of co-coordinating EU projects.  My research interests are in plant-microbe interactions and their applications for bioremediation of pollutants and sustainable agriculture. My current focus is on endophytic bacteria and their function as part of the plant and soil microbiota. In addition, I have an interest in the application of digital technologies relating to undergraduate science laboratory practical teaching/assessment. (see TEAM)

Publications

I have 25 years of experience in the area of biodegradation as well as plant-microbe interactions with over 70 publications in refereed international scientific publications and over 160 conference papers, three patents and I have edited a number of books in the area of environmental biotechnology.
