His research interests in the field of Solar Energy Applications are solar distillation, water/air heating system, greenhouse technology for agriculture and aquaculture, earth-to-air heat exchangers, passive building design, hybrid photovoltaic thermal (HPVT) systems, climate change, energy security, etc. He has guided about 75 PhD students and published over 550 research papers in journals of repute. He has authored twenty books associated with reputed publishers.He is a co-recipient of the 'Hariom Ashram Prerit S.S. Bhatnagar' Award in 1982. He had been to the University of Papua, New Guinea in 1987-1989 as an Energy and Environment Expert. He was also named European Fellow in 1997, and has been nominated for the IDEA award. He is responsible for development of "Solar Energy Park" at IIT Delhi and Energy Laboratory at University of Papua, New Guinea, Port Moresby. Dr. Tiwari has successfully coordinated various research projects funded by the Government of India. Dr. Tiwari was Editor of International Journal of Agricultural Engineering for the duration of three years (2006-2008). He is Associate Editor for Solar Energy Journal (SEJ) in the area of Solar Distillation and editor of the International Journal of Energy Research since 2007. He is also the Chief-Editor of Fundamental of Renewable Energy Applications and servers as a reviewer for many international journals. He was conferred the title of “Vigyan Ratna” by the State of Uttar Pradesh, India on March 26, 2008. He is also founder president of the Bag Energy Research Society that is responsible for energy education in rural India. Dr. Arvind Tiwari holds a Bachelor's degree in Physics, a Master of Science in Material Science from Jamia Millia Islamia, and a Master of Technology in Microelectronics from Punjab University (2002). He completed his PhD in 2006 from IIT DElhi(Hybrid Photovoltaic Thermal System). He is a post-doctoral fellow from University of Twente, Netherland. Besides, several other teaching engagements throughout his career, Dr Tiwari has worked as an Indian Expert in the capacity of senior lecturer in Manmohan Memorial Polytechnic, Morang, Nepal on deputation by the Government of India from January 2010 to January 2012. At present, he is working as Professor in Qassim University, Kingdom of Saudi Arabia. To his credit he has more than 20 research papers in international journals of repute.
