Dr. Casabianca received a B. S. degree in chemistry from Rice University in 2002 where she did undergraduate research with Prof. Seiichi P.T. Matsuda.  She completed her Ph. D. in the lab of Prof. Angel C. de Dios at Georgetown University in 2008.  Her thesis work involved using solution-state NMR and chemical shift calculations to understand the mechanism of action of anti-malarial drugs.  She then did a postdoctoral fellowship (2008-2010) with Prof. Yoshitaka Ishii at the University of Illinois at Chicago working on structural characterization of graphite oxide.  Her second postdoctoral fellowship was in the group of Prof. Lucio Frydman at the Weizmann Institute (2010-2013) where she worked on dynamic nuclear polarization of diamond samples.  She joined the faculty at Clemson University in 2014.

Research Interests

Research in the Casabianca group focuses on using Nuclear Magnetic Resonance (NMR) to study the interactions between nanomaterials and biological molecules.  As nanotechnology becomes more prevalent in our everyday lives, it is important to understand how nano-scale systems interact with proteins, lipids, and other biological ligands.  Studies involving interactions between nanomaterials and biological molecules have traditionally used low-resolution techniques such as Raman spectroscopy, electron microscopy, and circular dichroism spectroscopy.  NMR, on the other hand, is a local technique capable of providing atomic-level information about the electronic environment surrounding each atom.  In our lab we will use solution and solid-state NMR experiments, as well as theoretical chemical shift calculations and molecular dynamics simulations in order to shed light on the structure and dynamics of nanomaterial-ligand binding.  This multidisciplinary work has applications in the areas of biomedical devices, materials science, and nanoparticle toxicity.
