Research description:

I am interested in studying the complex coacervation of conjugated polyelectrolytes through experimental and computational methods. Understanding the thermodynamic, mechanical, electronic, and ionic properties of the complex fluids and materials produced by the self-assembly of charged polymers is of fundamental interest as a new opportunity for double-network gels. Tuning pi-stacking and coacervation parameters enables a new handling on these classes of materials. I am broadly interested in natural inspired polymeric and bioelectronics materials.

Brief Bio:

Originally from Virginia Beach, I started my career in 2009 in experimental physics at the Thomas Jefferson National Accelerator Facility. I graduated from Chemical & Biomolecular Engineering at the University of Pennsylvania in 2014. At Penn, I worked with Madeleine Joullié on natural inspired organic synthesis and with Russ Composto on polymeric brush stabilization of gold nanorods. Through various REU programs, I worked on a variety of ionic liquid, polymer, and bio-functionalized materials projects under Jason Bara (Alabama), Tim Lodge (Minnesota), and Michael Rubner & Robert Cohen (MIT). After graduation, I worked on lubricant modeling with ExxonMobil Research & Engineering.
