Department Of Biological And Agricultural Engineering, Manhattan, Kansas

- Conducted research into commingling of insect infested grain and adult insects in elevator equipment- Modeled the commingling using the discrete element method (DEM)- Conducted laboratory experiments to measure physical properties of insect-infested and sound grain kernels- Coordinated and networked with grain professionals, grain elevator managers, and farmers to invite collaborators for the stored grain pack factor project- Coordinated with seed producers and vendors in purchasing wheat seeds for compressibility lab analysis- Initiated the creation of website for the stored grain pack factor project- Gathered and analyzed data on grain bin load and headspace height for stored grain packing factor - Prepared reports and publications- Presented research results in local and international conferences - Supervised undergraduate students in their research work- Prepared research proposal for grant funding

Department Of Biological And Agricultural Engineering, Manhattan, Kansas

- Conducted experiments on dust sampling based on EPA method from repeated elevator handling of feed pellets, shelled corn, and wheat.- Analyzed the size distribution of particulate matter collected from bucket elevator handling and from cattle feedlot operation using laser diffraction method.- Characterized the durability of feed pellets and shelled corn after repeated mechanical stresses in bucket elevator handling.- Researched material properties (e.g., dimensions, density, and Poisson’s ratio) and interaction properties (e.g., coefficients of restitution and static friction) of grains and oilseeds for Discrete Element Method (DEM) modeling.- Used SolidWorks and DesignCAD-3D software to model detailed geometries of bucket elevator boots as inputs to DEM.- Created DEM simulation modeling of single- and multi-sphere soybean particle motion and compared models to experiments. - Extended best correlated DEM modeling techniques to grain commingling in bucket elevator boot.
