Water and Irrigation Researchers
Dr. Jonathan Aguilar is an extension water resource engineer for K-State, based at the Garden City area office. A native of the Philippines, Dr. Aguilar is an expert on water research issues, and his special focus is how these issues pertain to irrigated agriculture in central and western Kansas. His work for KCARE includes projects on new irrigation technologies such as Mobile Drip Irrigation (MDI), soil and plant water status sensors, and a new multi-year crop water allocation tool. He is also a part of on-farm research and demonstrations of new technologies to improve irrigation efficiency and reduce water consumption and researches the impact of poor water quality plant growth, development, and yield in central and western Kansas.
Dr. Aguilar received both his bachelor’s and master’s degrees in agricultural engineering from the University of the Philippines-Los Baños (UPLB). While there, his studies focused on land and water resources as it pertain to irrigated agriculture and environmental stewardship. After graduating, he continued to work at the university as a researcher as well as taking on several water resource-related projects with the UPLB Foundation, the Philippine Department of Agriculture, and the UN Food and Agriculture Organization. Dr. Aguilar came to K-State to pursue his doctoral degree in biological and agricultural engineering and graduated in 2009. He joined the faculty in 2012.

Dr. Trisha Moore is an assistant professor in K-State’s Department of Biological and Agricultural Engineering. Her research focuses on understanding and improving water quality, especially the processes by which natural-based engineered systems contribute to the production of ecosystem services (the benefits people obtain from those ecosystems). Dr. Moore’s studies examine the function of these systems at a variety of scales, from site-scale mechanisms to the watershed scale, and her research group explores questions regarding potential tradeoffs and synergies in the spatial and temporal delivery of ecosystem services under various watershed management approaches. Although the context for her research has been in urban or urbanizing watersheds, Dr. Moore’s research team also works in rural watersheds – like the Smoky Hill River watershed in Saline County – to study streambank erosion and discover new methods for streambank restoration. In addition to this work, Dr. Moore applied her research experience to the recent development of an integrated water quality program between the City of Wichita and upstream agricultural producers in the Little Arkansas River Watershed.
Dr. Moore graduated from K-State with B.S. and master’s degrees in biological and agricultural engineering. She attended North Carolina State University for her Ph.D. in biological and agricultural engineering, but returned to K-State in 2013 to join the faculty here.
