## Biography

Dr. Amalia Kokkinaki has been an Assistant Professor in the department of Environmental Science since 2016. She is an environmental engineer with expertise in groundwater flow, fate and transport of contaminants and biological treatment of organic pollutants. Her research is in the nexus of mathematical and statistical modeling of the physical, chemical and biological processes governing complex environmental systems. She was a postdoctoral researcher in the Department of Civil and Environmental Engineering at Stanford University from 2014-2016.

Amalia teaches undergraduate courses in the department of Environmental Science, graduate courses in the master’s program (MSEM) and in the Geospatial Analysis Lab (GsAL). Amalia is also in the curriculum committee for the new Engineering program at USF and is the faculty advisor for the Environmental Engineering and Science student club at USF.

In her research, Amalia uses statistical and mathematical modeling to simulate the behavior of pollutants in environmental systems. Her expertise is in understanding and predicting how pollutants get transported in the subsurface and how they change as they make their way through aquifers. She works with and develops computer models that simulate these processes and predict where, when and how much of the pollutant will be present in the environment. Some examples include: Modeling the fate of carcinogenic organic contaminants resulting from inappropriate waste disposal practices; Modeling of injection of supercritical CO2 (a liquid version of CO2) into deep geological formations to reduce CO2 emissions from industry; Modeling of groundwater levels near pumping wells and simulating the possibility of over-pumping and depleting groundwater resources. These models can be used to create engineering designs to clean up contaminated groundwater. Amalia combines these mathematical models with statistical models (a process called filtering) to help better determine the properties of the simulated aquifers. By combining statistics with mathematical models, we can try to quantify uncertainty and the value of information.

Amalia’s former students, ENVS alumni Letizia Tjiupek (ENVS 2018) and Matthew Hanson (ENVM 2017) are working on simulating the particular matter (PM) emissions from vehicles in Sacramento, and modeling the potential reduction of PM by urban forests. Her current research assistant, Abhinav Agrawal (ENGY 2019) is working on modeling and optimizing the electrification of developing urban areas.

Amalia is a big advocate of the value of learning how to program. Learning how to code is a skill that extends far beyond an employable skill: it is useful in developing process-oriented thinking, organizing and processing information and building a systems-level understanding of complex interrelated processes. All of these skills are critically needed in studying environmental phenomena. In Amalia’s research lab, my students learn how to use Matlab, Python or R for their various research projects. All of them have started from knowing little about programming to being able to confidently use, modify and develop code to run environmental models.
