Ms. Khanijo is an environmental modeler specializing in chemical fate and transport modeling including having experience in regulatory and higher-tier water quality exposure assessments of plant protection chemicals and veterinary pharmaceuticals in surface water and groundwater. She is also experience in watershed/national scale water quality modeling, probabilistic modeling, model calibrations and validation, inverse modeling, risk mitigation assessments using best management practices. She has applied her environmental engineering background and environmental modeling skills in the field of chemical regulatory science for over 10 years.

Ms. Khanijo skills include having expertise in various environmental and fate and transport model including ARCGIS, PEARL, MACRO, PELMO, PRZM, SWASH, SWAN, TOXSWA, KINGUI, CAKE, GENEEC, FIRST, SCIGROW, PRZM-3, PRZM-GW, EXAMS-II, LEACHM, and AgDRIFT, SWAT, APEX, RIVWQ, VFSMOD, MODFLOW, PEARLNEQ, CalEnviroScreen, AERMOD. She enjoys learning new models and applying her environmental modeling skills for problem solving and tackling unique/challenging environmental issues. Ms. Khanijo is also experienced in degradation kinetics for estimating modeling inputs.

Ms. Khanijo also has experience conducting field studies and collecting samples. Her M.S. research project involved conducting extensive field studies for evaluating performance of vegetated treatment systems used for biological treatment and control of wastewater from feedlots under the NPDES permits. During her research and working as a research assistant, she gained experience in construction and installing of flow monitoring devices and hydraulic structures such as ISCO samplers and analysis of flow data, hydrological data and water quality data (based on nutrients reduction) and use of statistical methods to evaluate environmental data.

She also has experience managing and leading projects and act as personnel manager and mentor to junior staff while working with the previous employer.
