Work History
Graduate Research Assistant Virginia Tech Chemistry Department 12/2012 to Present
I synthesized Poly(lactic acid-co-ethylene oxide) for potential drug delivery applications. Using a multi-inlet vortex mixer,
I was able to make micelle-like polymeric clusters to of uniform size to encapsulate guest molecules such as doxorubicin
and magnetite nanoparticles, to create theranostic agents. The polymer clusters were characterized by dynamic light
scattering, nanoparticle tracking analysis, transmission electron spectroscopy, and T1-weighted magnetic resonance
imaging.
I have gained significant polymer characterization experience by characterizing the thermal, mechanical, and conductivity
properties of many projects within the Riffle group. With each system, I work with my colleagues to understand the data
and determine the best way to convey the information to others.
Utilizing weak base, nucleophilic aromatic substitution, I synthesized poly(arylene ether ketone) for gas separation
applications and poly(arylene ether sulfone) copolymers for polyelectrolyte applications. Through this work, I contributed to
a patent for UV-crosslinkable polymeric gas separation membranes.
Undergraduate Research Assistant Southern Miss Polymer Department 10/2010 to 7/2012
In Dr. Kenneth Mauritz’s lab, I synthesized random and multi-block polysulfone systems using polycondensation methods
for polyelectrolyte applications. The copolymers were characterized by various thermal, mechanical, spectroscopic
techniques.
In Dr. Dan Savin’s lab, I synthesized block copolymers of polypropylene oxide and l-lysine using N-carboxyanhydride
ring-opening chemistry for potential drug delivery applications. Extensive characterization of the polypeptide copolymers
was done using both dynamic and static light scattering.
Ongoing Projects
There is a need for reduced fuel permeability in proton exchange membranes for water electrolysis applications; I am
synthesizing a crosslinkable hydrophobic block to be polymerized with a disulfonated hydrophilic block. I then solvent cast
the material via NMP or DMAc and further treat for optimal performance. I then characterize the material’s thermal,
mechanical, and conductive properties.
The state of the art process for creating carbon fibers from polyacrylonitrile is to spin the fibers from organic solvent,
however solvent based processing can be very expensive and environmentally unfriendly. Consequently, there is
significant interest in melt-processable polyacrylonitrile fibers, but the melting temperature overlaps with the onset
temperature of degradation by cross-linking. My work is to achieve melt processability of the carbon fiber precursor by
looking new polyacrylonitrile copolymers and their compatibility with a series of plasticizers. I then perform thermal and
rheological characterization to identify the difference among the potential plasticizers. This project is a collaboration
between Virginia Tech’s chemistry and chemical engineering departments as well as Oak Ridge National Laboratory.
