"I have a dream: safe water for all children" professor Andrea Iris Schäfer, KIT. In this episode, Rhea and I hosted Prof. Andrea Schaefer who develops reliable drinking water systems at an affordable price for several communities in Africa and abroad. These decentralized systems combine membrane technology with renewable energy. Moreover, she is researching and developing low pressure reactive membranes to remove endocrine disrupters from wastewater. It was inspiring to learn how her academic career started and how it developed over the years. Her vision and the key insights she shared with us in this episode can be valuable for junior researchers who would like to pursue an academic career.
