Christian Abraham Arega is interested in accessible health care as well as innovative ways to make health and wellness attainable for people in developing countries. This semester, Abraham Arega will be working with Professor Robert Nerenberg in the civil & environmental engineering department. One of the projects Abraham Arega will be taking on regards energy-efficient wastewater treatment using membrane-based biofilm reactors. Her research will specifically focus on exploring the possible existence of a higher density of bacteria in the high activity zone of a counter diffusional biofilm and what its implications are for biofilm modelling.
