Shrideep Pallickara is a Professor of Computer Science at Colorado State University. Pallickara’s research encompasses methodological and algorithmic innovations in three broad areas: (1) spatiotemporal data management and analytics, (2) file systems, and (3) stream processing for Internet-of-Things and Cyber Physical Systems settings. Systems software resulting from these research efforts have been deployed in domains such as brain computer interfaces, epidemiology, earthquake science, environmental and ecological monitoring, health care systems, high energy physics, defense applications, geosciences, GIS, and commercial internet conferencing systems. Pallickara is a recipient of the Monfort Professorship and the National Science Foundation’s CAREER award.

 Mazdak Arabi is a Borland Chair and Professor in the Department of Civil and Environmental Engineering at Colorado State University. Arabi’s research is primarily focused on development of decision support systems for management of water resources at the watershed scale. To make informed decisions, policy makers should have the tools necessary to identify areas that are most vulnerable to erosion and contaminant transport, and subsequently assess tradeoffs between environmental and economic impacts of management actions. Arabi has developed and demonstrated optimization-based approaches to facilitate development of watershed management plans that achieve water quality goals at significantly lower costs. He has published analytical and computational methods to support both deterministic and probabilistic evaluation of watershed-scale benefits of best management practices

Jay Breidt is a Professor and Chair in the Department of Statistics. His research focuses on statistical inference in finite population sampling and natural resources monitoring; his specific emphasis is on survey sampling, time series and uncertainty quantification. Breidt is the associate editor for the Journal of Forecasting, Environmental and Ecological Statistics. In 2004 he was recognized with the American Statistical Association Distinguished Achievement Award. Breidt is a member of the Federal Economic Statistics Advisory Committee. He serves on the US Bureau of the Census Scientific Advisory Committee and has served on six review committees for the National Academy of Sciences. Breidt is a Fellow of the American Statistical Association and a member of the International Statistical Institute.

Sudipto Ghosh is a Professor of Computer Science at Colorado State University. He received the Ph.D. degree in Computer Science from Purdue University in 2000. His research interests are in the areas of modeling and testing software in the object-oriented, aspect-oriented, and component-based paradigms. Specific topics include data warehouse testing, fault localization, model-based software development, mutation testing and higher order mutation, and regression test selection. Ghosh is on the editorial boards of IEEE Transactions on Reliability, Software Quality Journal, and Information and Software Technology

Sangmi Pallickara is a Cochran Family Professor and an Associate Professor in the Computer Science Department at Colorado State University. Pallickara’s research interests are in the area of Big Data for the sciences with an emphasis on issues related to predictive analytics, storage, retrievals, and metadata management. She is the Associate Editor of the IEEE Transactions on Parallel and Distributed Systems and serves on the editorial board of the Journal of Big Data, Springer. She is a recipient of the IEEE TCSC Award for Excellence in Scalable Computing (Mid-Career) and the National Science Foundation’s CAREER award.

Mikhail Chester is an Associate Professor of Civil, Environmental, & Sustainable Engineering at the Arizona State University. Chester’s research focuses on the increasingly complex challenges for infrastructure in the Anthropocene. A key goal in Chester’s research is to provide insights into how we can transition the management and design of infrastructure in the face of increasing complexity characterized by accelerating and increasingly uncertain conditions such as emerging and disruptive technologies (including artificial intelligence), climate change, financing, and cybersecurity/warfare. This work has led to recommendations for transitioning how we govern, educate for, and build infrastructure for the future.

Amir AghaKouchak is a Professor of Civil and Environmental at the University of California, Irvine. His research aims to bridge between the disciplines of hydrology, climatology, and remote sensing to address critical global water resource issues. AghaKouchak is particularly interested in combining remote sensing techniques and physically-based and statistical approaches in order to develop more reliable models of large-scale hydrologic systems. The long-term research objective is to utilize continuously growing satellite data along with ground-based observations to develop/improve integrated drought, flood and landslide modeling, prediction and decision support systems.

Claire Welty is a Professor of Environmental Engineering and the Director, Center for Urban Environmental Research and Education at the University of Maryland Baltimore County. Welty’s interests are in developing an end-to-end system of field-deployed sensors and fully coupled groundwater-surface water mathematical models to quantify and predict the urban hydrologic cycle and coupled biogeochemical cycles from neighborhood to regional scales. A key goal is to be able to assimilate sensor data into hydrologic and water quality models in near-real time for predicting flow paths, fluxes and stores of water and chemicals on land surfaces and in the subsurface. Welty works in collaboration with the NSF Baltimore Ecosystem Study Long-Term Ecological Research Site and the USGS MD-DE-DC Water Science Center. While methods are being developed using place-based research in Baltimore area, the methods are widely applicable to other urban areas.
