I am a researcher/academician with an academic background in plant biology (specialization in greenhouse technology). Over 10 years’ experience in research and development projects. I have strong scientific background and experiences in project design, organization and implementation in plant eco-physiology, modelling climate effects in closed cultivation, biodiversity, biogas process and biogas-farm integrated system. A dynamic, team-spirited, and bottom-line-oriented research professional dedicated to result oriented research outputs through continuous improvement.
