Biography

PhD (2008) in photosynthesis research from Devi Ahilya University, Indore, India; Postdoctoral Researcher (2007 to 2009, and 2012) in Department of Biophysics, Palacky University Olomouc, Czech Republic; From 2009 to 2011 worked as a metabolomics research Scientist in a Bionutrition and Pharma industry: From 2013 onwards Postdoctoral Research in Plant Molecular Biology, University of Turku, Finland .

Research

Dr. Arjun Tiwari is currently working on bioenergetics of photosynthetic regulation through possible redox communication between chloroplast and mitochondria. He is studying location of reactive oxygen formation in photosynthetic electron transfer chain and their role in photosynthetic controls.
