Prof. Amisha Shah
Dr. Amisha Shah, an assistant professor in Environmental and Ecological Engineering as well as Civil Engineering, has strived over her research career to evaluate how chemical reactions in water affect natural and engineered systems. Such work is considered to have important implications for water quality as well as to human and ecosystem health.
Dr. Shah received her B.S. in Chemical Engineering from Washington University in St. Louis and her Ph.D. in Environmental Engineering from Georgia Institute of Technology. She also worked as a post-doctoral associate at Yale University as well as a research associate at the Swiss Federal Institute of Aquatic Science and Technology (EAWAG), prior to joining Purdue.
In her recent efforts, she has placed an important focus towards evaluating how chemical interactions in aqueous systems can be strongly influenced by their surrounding water matrix. This work has been targeted in an ongoing NSF-funded research project that has evaluated how the presence of halides can control the degradation kinetics of membrane surfaces that are commonly used for desalination and water reuse. Similarly, other research efforts have found that different water quality parameters can significantly influence disinfection by-product formation from cross-linked polyethylene (PEX) pipes that are routinely used in premise plumbing systems.
Moreover, a broader outlook for her research has also been achieved by addressing environmental issues such as climate change. Her research in this area has found that different water types ranging from freshwater to open ocean waters can strongly influence how organic sulfur compounds photochemically produce volatile sulfur compounds, which can trigger climate cooling.
