Rajesh Singh

Postdoctoral Researcher

Indian Institute of Technology (IIT) Gandhinagar

"I am a hydrologist with expertise in hydrological and climate modeling, examining the impacts of climate change and human activities on global water resources. My current research focuses on monitoring and predicting meteorological and hydrological extremes through advanced hydrological models.
I have completed my Ph.D. in Civil Engineering from IIT Gandhinagar. Throughout my doctoral studies, I focused on studying the drivers of hydrological flash droughts in India. Prior to my current position, I contributed to a UNICEF project that aimed to develop a Real-time Hydro-Meteorological Monitoring and Forecast for Karnataka state."
