After having PhD from the River Engineering Laboratory of Kyoto University in 1998, I started working as an Assistant Professor at Institute of Water and Flood Management (IWFM), Bangladesh University of Engineering and Technology (BUET) and became professor in 2008. As a fellow of Japan Society of Promotion of Science at the Disaster Prevention Research Institute (DPRI), Kyoto University during the period of 2002-2004, we explored indigenous techniques for sediment management which is being practiced in Bangladesh as nature-based solution for river management.
Since 2010, as a Principal Investigator of a number of large transdisciplinary research projects funded by different international agencies such as DFID/UKAID, JICA, IDRC, UNDP along with the Government of Bangladesh, I had the opportunity to lead big trans-disciplinary team to explore the consequences of climate change on disaster management, ecosystems services and migration and adaptation in the GBM and other deltas. The techniques and system level models (such as Cyclone Classifier Model, Dynamic Flood Risk Model, Dynamic Adaptation Model) developed through these initiatives are being utilized in the mainstream decision-making processes in relevant sectors of Bangladesh for planning, development, warning and adaptations. I worked as a focal point to guide the formulation team of Bangladesh Delta Plan 2100 through sharing the above scientific results for the policy-planning.
