Varenyam Achal is a Professor appointed by the Technion-Israel Institute of Technology. He joined GTIIT’s Environmental Engineering Program in September 2018. Prof. Achal was awarded a PhD from Thapar University, India. Prior to joining GTIIT, he was Professor at East China Normal University, Shanghai. He was Assistant Professor at Chinese Academy of Sciences (CAS) between 2010 and 2012 during which he also obtained International Young Scientist fellowship from CAS. Dr. Achal has a very board interest in environmental biotechnology and biological based building materials. He has authored more than 50 SCI papers in journals of repute along with several book chapters and one book. He is member of the Editorial Board of Socio-Ecological Practice Research and has been Guest Editor for Frontiers in Microbiology. Some of his original research has had a global impact on microbially induced calcite precipitation and attracted worldwide attention.
