Bijay Shakya
Nepal
Dr. Shakya obtained his Ph.D. at the Department of Natural, Biotic, and Social Environmental Engineering from the University of Yamanashi, Japan in March 2020. He completed his Master’s degree with a specialization in Hydrogeology from the Department of Geology, Tribhuvan University, Nepal. With the combined support of the University of Yamanashi, Japan International Co-operation Agency (JICA), Japan Science and Technology (JST), and Kathmandu Valley Water Supply Management Board (KVWSMB) he is eager to connect the dots in identifying the groundwater system of the Kathmandu valley, Nepal. Dr. Shakya is also undertaking research on municipal tap water systems of the Kathmandu valley using isotopic approaches with the aid of the International Atomic Energy Association (IAEA). Besides that, he has gained experience in restoring the mountain springs and designing deep tube wells for deep groundwater extraction and water management practice for irrigational purposes in Nepal. He has collected various national and international working experiences on research and management of surface and subsurface water resources. He is dedicated to research activities for the sustainable watershed management practice in Nepal and is delighted to be a part of S4W-Nepal in linking the ideas of the citizen scientist and young scientist for the broader scientific research.

Steve Lyon
Steve Lyon was born and raised in Navarre, Ohio, USA. He attended Purdue University and graduated with a BSc (1997-2001) in Agricultural and Biological Engineering and a minor in Mathematics. Steve completed his MSc (2001-2003) and PhD (2003-2006) both in Biological and Environmental Engineering at Cornell University looking at how we incorporate the spatial structure of shallow water tables into hydrology. He continued with postdoctoral research (2006-2008) at the University of Arizona focusing on the evolution of land-water interaction in space and time. Steve joined the Department of Physical Geography at Stockholm University in 2008 promoting to Associate Professor (2010) and then Full Professor (2016). During this period, he also worked with The Nature Conservancy (2017-2019) as a Freshwater and Conservation Scientist.
In August 2019, Steve joined the faculty in the School of Environment and Natural Resources at Ohio State University as an Associate Professor. Working in hydrology and water resources, Dr. Lyon’s research targets characterization of land and water interactions. Unraveling feedbacks across scales has significant implications for the viability of strategies associated with the current and future sustainability of coupled terrestrial and aquatic systems – particularly those for improving water quality in working landscapes.

Martine Rutten
Martine Rutten investigates how information systems (combination of models, remote sensing, and ground data) can effectively support adaptive delta and water management in developing countries. Key elements of this research include developing systems together with local parties and providing actionable perspectives. Case studies of this work are underway in Vietnam, Myanmar, and Nepal. Work includes inclusive development paths for Red River Landscapes based on ecosystem services reservoirs management for the Day River, a Red River sub-basin reservoir management for flood control in the Sittaung-Bago River in Myanmar-Coastal squeeze in the Ayarawady delta analyzed from remote sensing.
