Biography
Ashish is a Professor of Civil and Environmental Engineering at the University of New South Wales, Sydney, Australia. He is an engineering hydrologist interested in problems involving hydrological uncertainty. Much of his research has focussed on the impact of climate change and variability on hydrological practice, along with applications related to remote sensing, formulating stochastic approaches, developing hydrological models, and the two big hydrology bread-and-butter problems – design flood estimation + water resources management.
