Former CENR Researchers

Kamal Kadel, PhD

Dr. Kamal Kadel is currently a postdoctoral fellow in Professor Lead’s group at the CENR. He earned his Ph.D. in Physics from Florida International University, Miami, FL. During his Ph.D., he gained the expertise in synthesis and characterization of various inorganic nanomaterials, which find applications in various fields such as clean energy production and environmental remediation. His current research in CENR focuses on the large scale synthesis and characterization of polymer coated iron oxide nanomaterials and their application to the environmental remediation.

Ruth Merrifield, PhD

Dr. Ruth Merrifield is a Research Assistant Professor within the CENR. She earned her PhD in nanoscale physics at the University of Birmingham (UK) followed by a postdoctoral position in nanoecotoxocology at the same university, combining her interest in the environment with her love of physics. Her research interests are based around the effect of environmental and toxicological media on the state of nanoparticles (particularly oxidation states, surface interactions and dissolution rates) and how this affects the transport, uptake and toxicity of nanoparticles. Current projects include; The synthesis of core-shell structured metal nanoparticles and their transformations; Algal and daphnid uptake and toxicity of ceria nanoparticles; The effect on ceria nanoparticle chemistry due to ecotoxicological and environmental conditions; The fate and behaviour silver nanoparticles in waste water treatment plants and surface waters.

Soubantika Palchoudhury, PhD, MS

Dr. Soubantika Palchoudhury was a postdoctoral fellow at the CENR. Her research investigated novel, surface-engineered nanostructures for environmental remediation techniques. She is highly skilled in the synthesis and surface modification of anisotropic nanoparticles, DNA-nanoparticle interaction, and characterization techniques such as transmission electron microscopy. Prior to her research at USC, she was a postdoctoral researcher at Yale University. She completed her Ph.D. and M.S. in Chemical Engineering from the University of Alabama on the synthesis and characterization of Pt decorated iron oxide nanoparticles for biomedical applications. She has published over 10 articles in nanoscience journals such as Nano Letters, Langmuir, and ChemComm. She has authored a book chapter and has reviewed for APL, JAP, Nanotechnology, and Nanomater, Nanotechnol.

Daniel Ross, PhD

Dr. Daniel Ross was a research assistant professor in the Department of Environmental Health Sciences in the Arnold School of Public Health at the University of South Carolina.  His research interests involved bioenergy, the use of microorganisms for the production of biofuels, and the interaction of bacteria with solid surfaces (e.g. minerals in the environment, electrodes in electrochemical systems, and nanoparticles/nanomaterials in the environment).   Dr. Ross examined the effects of nanomaterials on microbial populations and their metabolisms to elucidate microbial mechanisms involved in the fate and transport of nanomaterials in the environment. 

Caixia Yan

Caixia Yan was a Ph.D. candidate studying at East China Normal University (ECNU) in Shanghai, China. She visited the University of South Carolina for one year. Her research was primarily related to the occurrence, distribution and fate of emerging organic contaminants (EOCs) in the aquatic environment, especially their sorption behavior to naturally occurring carbonaceous geosorbents and nanoparticles (NPs). The aim of her work with the CENR was to characterize aquatic colloids and NPs in different size fractions in order to better understand the formation and transport of the NP-EOC complexes. In addition, she aimed to help to unravel the underlying mechanisms of NP-controlled EOCs behavior in estuarine aquatic system.

Amal Zaidan

Amal Zaidan is a PhD student at the CENR, and started her research under the supervision of Jamie Lead in October 2014. She earned her Master’s degree in Public Health from Rollins School of Public Health at Emory University, Atlanta, GA in 2014. Her current research interest is in the synthesis and characterization of polymer coated iron oxide nanomaterials, and their effectiveness in removing food oil derivatives from biological media. Specifically, she is researching their possible applications on weight gain in vivo.
