Sagnik Bhattacharjee, MSc., graduated with a Masters in City and Urban environment with a specialization in Atmosphere, Water and Urban Environment from Ecole Centrale Nantes, France in 2018. He is passionate about urban resilience to climate change impacts, environmental impact in urban ecosystem, and the use of nature-based solutions to mitigate the impact of climate change in cities. In 2018, he co-founded ECOTEN Urban Comfort s.r.o., an urban environmental consultancy focused on the climate adaptation of cities and is currently working there as the CTO. He conceptualized the measurement of urban heat vulnerability index (UHVI) which was mentioned in the European Handbook for SDG Voluntary Local Reviews 2020 published by the Joint Research Centre of the European Commission as an exemplary indicator for European cities willing to take action on SDG goals through voluntary local review.  He manages the urban heat vulnerability assessment services with GIS and remote sensing technology for measuring the UHVI for city planners and urban developers and the urban microclimate simulation assessment services with the urban environmental software suite SOLENE-microclimat for urban development stakeholders. He is also managing the commercial development of the SOLENE-microclimat and the development of API services for urban heat vulnerability assessment with funding from ESA BIC Czech Republic. He is responsible for the integration of new methods, frameworks and technologies to optimize the assessment of climate change vulnerability and develop NBS based urban design for urban resiliency for cities. As of 2023, he is the author or co-author of 3 scientific papers and is also leading the participation of ECOTEN urban comfort s.r.o. for Horizon Europe project “Re-Valuing Urban Quality & Climate Neutrality in European Waterfront Cities” co-funded by the European Union.
