Research Interests

Ecohydrology, solute and sediment transport at various spatial/temporal scales, development and assessment of best management practices to minimize nonpoint source pollution, spatial variability of natural processes that control hydrologic/water quality watershed response, effect of land use on sediment, nutrient and metal transport, interaction of terrestrial and aquatic processes affecting water quality and linking these processes to develop integrated watershed/water quality management technology, mathematical modeling of sediment, nutrients and metals at different spatial scales, and application of geographic information systems and remote sensing in developing decision support system for ecosystem management.

Awards/Honors Appointment/Elections

  • Outstanding Engineer Award (2006)

  • Faculty Research Award of Merit (2006)

  • ASAE Honorable Mention Paper Award

  • Best Teacher Award, 2005.  Biological Engineering Student Club, University of Arkansas.

  • Outstanding Researcher Award (2002- 2003)  Department of Biological and Agricultural Engineering.  University of Arkansas, Fayetteville.

Professional Experience

  • Chair, Arkansas Section of the ASABE.  2004-2005.

  • Chair, SW-21 (Hydrology Group).  2005-2006.

  • Member, Environmental Task Force, CAFLS and the Division of Agriculture, University of Arkansas.  2002 – 2006.  I was selected by the University of Arkansas Division of Agriculture to take a leadership role (with Dr. T.C. Daniel) in developing this computer software to prepare nutrient management plan for animal waste management in the Eucha-Spavinaw watershed.

  • Chair, Graduate Committee, Department of Biological and Agricultural Engineering,  University of Arkansas. 2005 – 2006.  As the Chair of this committee, I had taken a leadership role in developing policy for qualifying examination and candidacy examination for Ph.D. students, and criteria for deficiency courses for students admitted in the program without an engineering degree.  In addition, the graduate committee oversaw the graduate curriculum and all graduate admissions in the department.

  • Ecological Engineering Committee, Department of Biological and Agricultural Engineering, 2002 – 2006. Chair, 2000-2003.

  • Academic Matters and Curriculum Committee, Department of Biological and Agricultural Engineering, 2002 – 2006.  Worked with other faculty members to prepare ABET materials.  This involved extensive review of course materials, educational outcome assessment, and document preparation.  Worked with other faculty members to revise BENG curriculum, including review of credit hours required for degree in BSBE, review of required and elective courses, sequencing of course offerings, and revision of some of the course materials (e.g., BENG 4903: Natural Resources Engineering).
