CEA-CREST Research Experience for Undergraduates: Sensors for Environmental Science/Engineering

REU Goal Develop/Build/Assemble/Implement sensors to monitor the environment Four projects –Building a flow-through arsenic/phosphorus sensor –Building a tram/UAV-based mini remote-sensing platform –Implementing a field-scale sensor network to monitor wave flow over a mussel bed –Building a manifold to sample and analyze combustion effluent Work in groups of scientists and engineers – one goal but separate and definable tasks

REU (cont’d) 10 weeks: Starting today through August 18 th 2 required field experiences (UCLA and UC Merced) 1 optional field sampling trip (Hot Creek) (Note: depends on funding) Will work directly with program directors and mentors

REU (cont’d) For undergraduates (need to graduate at the end of or after Summer 2006) For citizens or permanent residents Rules: –Can take classes but by permission only –Cannot work outside REU (unless absolutely necessary and with permission) –40 hours/week –Roughly a Monday through Thursday schedule

REU (cont’d) Grounding Workshops –Biogeochemical cycles –Research design and data analysis –Transport phenomena –Hands-on sensor development Diversity presentation (joint with UCLA)

Program Directors Crist Khachikian, Ph.D. –Associate Professor, Civil Engineering –Expertise Groundwater contamination and remediation Air-water contaminant transport Darrell Guillaume, Ph.D., P.E. –Professor, Mechanical Engineering –Expertise Fluid mechanics/dynamics Mixing/combustion

Program Assistant/Office Ms. Elisa Brown Center for Environmental Analysis (CEA- CREST) –Also NSF funded –Theme: spatially structured dynamics –14 faculty from biology, chemistry, civil engineering, geography, geology, political science –New M.S. in Environmental Science (+ physics, mathematics, sociology, etc.) –UMEB Fellowship opportunity
