Position(s) available
  • Positions at the International Centre for Clean Water (ICCW)

  • International Centre for Clean Water (ICCW) is our new initiative. See the link below for more details. The objective of this interdisciplinary centre is to build clean water technologies right from the work bench and translate them to products, creating companies in the process. It will also implement technologies. Any individual, institution or company is welcome to participate and co-create in the area. It will be a place for all to innovate around water. We are looking for certain key people in the areas of materials, biology, membranes, computational materials science, product design, and analysis around this theme. PhD/MTech/MSc/MBA level scientists/engineers/managers are welcome. They should have a flair for innovation.​ Compensation will be comparable to the best in this domain. Contact the CEO, Mr. E. Nandakumar at enandu@hotmail.com.​
