Sheila Christopher

Sheila Christopher

Sheila Christopher is a Research Assistant Professor working with Dr. Jennifer Tank on the Land use and Water Quality program at ECI.  Her research interests are in Watershed Hydrology and Biogeochemistry.  Her research is driven by a need to understand the effect of land use change, global climate change, and other disturbance on biogeochemical cycling and water and solute transport through watersheds.  She has worked in natural, agricultural, and mixed land use systems and has used both field measurements and models to answer research questions.  At ECI, she will use hydrologic models and watershed monitoring to understand how water resources are affected by best management practices (BMPs) at the watershed scale.  Sheila received her BS from Allegheny College and her PhD from State University of New York, College of Environmental Science and Forestry.   

 

Thanuka Wickramarathne

Thanuka Wickramarathne

Thanuka Wickramarathne is a Research Assistant Professor with the Department of Electrical Engineering. His research falls under the umbrella of multi-sensor data fusion---a broad interdisciplinary field of research that overlaps many diverse areas, such as signal processing, estimation and detection, information theory, artificial intelligence, and probability theory. At ND-ECI (under a project funded by NSF Coasta lSEES, 2014--2019), Thanuka works with Prof. David M. Lodge on developing a risk assessment system for biological invasions via global shipping network, where he investigates the complex fusion problem of integrating heterogeneous and extremely sparse global shipping network, climate and environmental condition data. In addition, his current research interests are in the general areas of sustainability of transportation, intelligent transportation systems, signal processing for big-data, estimation & detection in highly uncertain environments, and consensus formation & convergence properties in adaptive multi-agent systems. Thanuka received his B.Sc. in Electronics and Telecommunication Engineering in 2006 from University of Moratuwa, Sri Lanka. He received his MS and PhD in Electrical and Computer Engineering from University of Miami, Coral Gables, FL in 2008 and 2012, respectively.
