While pursuing BSc. (Hons) Mathematics from UPES, I attended a workshop by WaterScope and VigyanShaala on ‘Sustainable Development’. The workshop focused on water quality testing led by a team of researchers from Cavendish Laboratory, University of Cambridge. I also got a chance to intern with the same. My co-intern and I reached Cambridge on August 1 last year. Dr. Nalin Patel showed us Cavendish Laboratory where we were going to work for five weeks. He explained the project and our responsibilities. We worked under Dr. Alexander Patto and Dr. Alicja Dabrowska who were extremely supportive. We collected and tested around 100 samples and learnt 3-D print and assembly of the WaterScope system. It was a great learning experience and I shall be forever grateful to UPES.
