JORGE A. GUZMAN

jorge.guzman@ou.edu

I am an environmental modeler using deterministic, conceptual, data-driven, and stochastic model approaches to understand complex system responses at the surface and sub-surface domains. My expertise encompasses hydrological, environmental, and feedbacks processes (physical, chemical and biological) linked to surface-subsurface water interactions.

EDUCATION    

  • Ph.D. Biosystems and Agricultural Engineering, Oklahoma State University, Stillwater, OK, USA 2010
  • Master of Science in Hydrology and Water Resources, UNESCO-IHE, Delft, The Netherlands, 2003
  • Master of Science in Computer Science, Universidad Industrial de Santander, Bucaramanga, Colombia
  • Diploma in Photogrammetry and Large scale DEMs for Civil Engineering, IGAC, Bogotá, Colombia
  • B.S. Civil Engineering, Universidad Industrial de Santander, Bucaramanga, Colombia

WORK EXPERIENCE    

Senior Engineer, Waterborne Environmental, Inc., Champaign, Illinois, October 2014 to April 2016.

Dr. Guzman actively participate in the modeling group providing scientific support and leading tasks on hydrologic, environmental, statistics, and modeling of transport phenomena within projects for clients like Syngenta and the Illinois Corn Grower Association. Also, he led the development of applications for data manipulation and model automation for the PRZM and SWAT models; distributed hydrologic modeling, joint probability for risk assessment of unusual concentrations; model evaluation and performance, and downscaling synthetic rainfall patterns.

Research Hydrologist - Postdoctoral Fellow, USDA-ARS Grazinglands Research Laboratory, El Reno, OK, June 2011 – September 2014

Dr. Guzman conducted surface-groundwater investigation in the Fort Cobb Reservoir Experimental Watershed (FCREW) in Oklahoma. In this investigation, Dr. Guzman developed a modeling framework integrating the SWAT, MODFLOW, and ET Energy Balance models. In this research two applications were implemented: 1) SPELLmap to facilitate big-data processing and analysis of geolocated data, and 2) SWATmf to support the surface-subsurface model integration framework. In the USDA-GRL he developed a methodology for conducting sensitivity and uncertainty analysis in the APEX model, support field data collection (groundwater, soil, and meteorological variables), deployment of automated water samplers in the Fort Cobb and Little Washita watersheds, and development of groundwater monitoring wells in the FCREW in cooperation with USEPA.

Graduate Research Associate, Department of Biosystems and Agricultural Engineering, Oklahoma State University, Stillwater, OK, August 2007 – December 2010

Dr. Guzman conducted research, developed reports and publications, and assisted in grant writing for future funding on soil fecal bacteria transport, primarily focusing on preferential flow mechanisms. He led a research team including Master of Science and undergraduate students on this research project
