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.

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

Research Lab: Multiscale Energy Transport and Materials Laboratory
Specialty: Multiscale Energy and MaterialsThe work of the Multiscale Energy Transport and Materials Laboratory focuses on studying and engineering how thermal energy moves through materials and devices at the macro-, micro-, and nanoscale. We’re particularly interested in nanomaterials, thin films, 2D ultrathin materials, and composite or scalable materials that incorporate these types of structures. Applications include energy scavenging, energy production, sustainable alternative materials, advanced manufacturing, chemical and environmental sensing, and advanced thermal management materials and techniques for everything from electronic devices to large industrial processes. This work encompasses experimental studies as well as numerical modeling efforts, often working in tandem to provide the most complete picture possible of the processes at work within the system or material under study. It is our goal that our research results in the design, development, and implementation of highly effective energy solutions across a variety of applications, the realization of improved models and design tools for multiscale energy systems and materials, and a deeper understanding of energy transport in general.

Fundamental Forces and Components of Nature & High Energy Particle Interactions

Dr. Sawyer’s work is focused on understanding the most fundamental forces and components of nature through the study of high-energy particle interactions. This research is currently centered on the ATLAS experiment at the Large Hadron Collider, or LHC, located at the CERN international particle physics laboratory near Geneva, Switzerland. As a member of the ATLAS experiment, Sawyer was among the scientists who discovered the Higgs boson in 2012. Using data from the ATLAS experiment, Sawyer and his colleagues have made measurements of the strong coupling constant, a fundamental constant of nature that describes the strength of the interactions between quarks and gluons. He has also searched for new particles and interactions beyond the Standard Model of particle physics. In addition to these physics analyses, Sawyer has developed software for the ATLAS experiment. He also works on detector development activities for future experiments. Dr. Sawyer is currently funded by the National Science Foundation.

Micro and Nanotechnologies

Headshot of Dr. Yuri LvovDr. Yuri Lvov
Specialty: Layer-by-Layer NanoassemblyA 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.
