Dr. Leon Iasemidis
Specialty: Brain Dynamics
Research Lab: The Brain Dynamics Laboratory

Research in the Brain Dynamics Lab focuses on the design and implement novel methodology and advanced signal processing techniques to monitor, process and model the electrical and magnetic activity recorded from the brain for the purpose of diagnosis, differential diagnosis, evaluation of treatment, timely warning and intervention to avert catastrophic state transitions like epileptic seizures. The secondary goal is to interface the developed products with existing devices in biomedical industry used for monitoring and real-time treatment of the respective disorders, diseases and emergencies, for example, vagus nerve stimulators (VNS), deep brain stimulators (DBS), transcranial magnetic stimulators (TMS) and/or other neuromodulation devices based on timely in situ cooling of the brain or in situ administration of medication.

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 pre-set 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 (EPSCORE). 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.
