Research Lab: Caldorera-Moore Lab – Therapeutic Micro- and Nanotechnology Biomaterials
Research in the Caldorera-Moore lab combines micro- and nanoscale technologies with intelligent biomaterials to create new and improved biomimetic platforms for studying the influence chemistry, surface topography, and material properties play on directing cell fate or the ability to respond and release therapeutics. The broader impacts of this work are for the development of innovative systems for targeted, cell-specific responsive drug delivery and regenerative medicine applications.

Micro and Nanotechnologies

Dr. Yuri Lvov
Specialty: Layer-by-Layer Nanoassembly

A layer-by-layer (LbL) assembly of alternating layers of oppositely charged polyelectrolytes and nanoparticles provides the formation of 5 – 500 nm thick films with monolayers of various substances growing in a preset sequence on any substrates at a growth step of about 1 nm. This technique was called “molecular beaker epitaxy” meaning by this that with simple instruments (exploiting the materials self-assembly tendency) one can get molecularly organized films similar to the ones obtained with highly sophisticated and expensive molecular beam epitaxy technology for metals and semiconductors. LbL films can coat solid supports, slides, silicon wafers, plastics and fiber optics (2D nanoassembly). Besides, LbL films can be assembled on micro- and nanotemplates, such as 100-500 nm diameter latex, drug microcrystals, biological cells and even viruses, provided by this method for 3D nanoassembly. Polymeric nanoshells also can be prepared with LbL assembly.

Research Lab: Energy Harvesting and Microsystems Lab
Specialty: Energy Harvesting

The Energy Harvesting and Microsystems Lab research encompasses experimental studies as well as numerical modeling efforts. The main goal of our research is to apply fundamental engineering concepts to design and develop technologies. As a result, our research process goes through a cycle of design, modeling, fabrication, testing and characterization, analysis, optimization, and prototyping. Our research is funded through few agencies including The National Aeronautics and Space Administration (NASA), Louisiana Board of Regents (La BoR), the Louisiana Space Consortium (LaSPACE), and the NASA Experimental Program to Stimulate Competitive Research program (EPSCOR). We also partner with NASA Stennis Space Center and Radiance Technologies. Current Research themes and projects include:

  • Nonlinear dynamic vibration systems in micro and macro environments,
  • Design, modeling, and characterization of vibration energy harvesting,
  • Design, modeling, and characterization of Vibration isolation systems, and
  • Exploring vibration systems subject to combined stiffness and damping nonlinearities.

Transportation and Infrastructure

Specialty: Underground Infrastructure
Research Center: Trenchless Technology Center

Dr. Matthews’s research at the TTC focuses on various topics impacting underground infrastructure assessment, rehabilitation, and replacement, including predictive risk modeling for buried assets; development and validation of innovative materials for pipeline, liner, and other structural civil applications; and evaluation of environmental impacts and benefits of trenchless technology methods. The impacts of this work help to improve the asset management strategies of engineering practitioners trying to maximize the return on investment for buried infrastructure funding.

Dr. Rakitha Beminiwattha
Specialty: Particle Physics

Dr. Beminiwattha’s research is focused on weak mixing angle measurements primarily at low energies for precision tests of the Standard Model of Particle Physics (SMPP) utilizing parity-violating electron scattering (PVES), MOLLER and Qweak experiments at the Jefferson Lab in Virginia, and the P2 experiment at the MESA facility in Germany. Major funded projects are to design and develop charge particle detection systems for the MOLLER experiment, to design an electron detector for a polarimeter, to design radiation shielding measures for MOLLER, and the theoretical interpretation of the Qweak auxiliary data. Dr. Beminiwattha is currently funded by the Research Competitiveness Subprogram of the Louisiana Board of Regents and National Science Foundation.
