Fresh water resources are inherently limited by their quantity, and this has drawn the world’s attention. As an independent scientist, I will focus on improving membrane-based desalination technologies, such as ED/EDR, EDI, and FO, as well as other desalination technologies, in order to reduce the energy and cost requirements of these processes without impacting their performance. Additionally, I will work on using renewable energies, especially solar energy, to provide off-grid desalination systems for rural, remote off-grid areas and provide water for people who are suffering from fresh water scarcity.

“Theoretical, Experimental, and Predictive Models for Ion Removal in Electrodialysis and Electrodialysis Reversal”
During my Ph.D. studies, I conducted experiments on pilot-scale EDR at the Brackish Groundwater National Desalination Research Facility (BGNDRF) in Alamogordo, NM. These experiments provided me with a general idea of how operating parameters affect the removal of different ions in the EDR process. Utilizing this data, I designed and built a complete laboratory-scale ED system equipped with a complete data acquisition system. The reason that the data acquisition system was designed and used in this system was to continuously and accurately monitor and record the operating conditions during the entire set of experiments. The collected data was used in developing an empirical model to predict the removal of monovalent and divalent ions in the ED/EDR process at various operating conditions. The developed dimensionless model can be widely used for full-scale electrodialysis operations for which the removal of specific ions is desired.
Prior to attending NMSU, I independently instructed a number of undergraduate courses, such as Mass and Energy Balance, Organic Laboratory, and Chemistry Laboratory. During my Ph.D. studies, in the role of Future Faculty Fellow, I independently taught 5 sessions on heat exchangers, held review sessions, and assisted in quiz and exam question development. Additionally, I individually taught a number of chapters and sessions and desiged the quizzes of an Engineering Data Analysis course. I have been assigned as the instructor of this course for spring semester of 2016. Additionally, I have served as a TA and guest lecturer for several undergraduate courses.
As a faculty member, I would like to continue my research in the water-energy nexus. Desalination process optimization, which is one of my interests, can be viewed from several perspectives. The optimization process can be conducted either by decreasing the cost of the process or by increasing the sustainability of the process. Moreover, the desalination process as a whole can be improved by the hybridization of different processes. The utilization of renewable energy resources in desalination processes, which is my second research area, can reduce the operating cost of the process.
My short- and long-term research objectives give me confidence that I will be able to obtain funding and add significant improvements in areas related to the water-energy nexus; this wide research area will provide enough opportunity for me to improve the efficiency and sustainability of desalination systems to help provide fresh, safe water for people who currently do not have access to it. Based on my experience in the area of the water-energy nexus, I will be able to establish a strong collaboration with industry and academia to make my research objectives achievable.
