PhD Candidate Eredzhep Menumerov - "Novel Nanomaterial Fabrication Techniques for Catalysis, Sensing, and Electronics"
Materials with nanoscale dimensions allow for the exploitation of a set of unique and often extraordinary properties originating from finite size effects. The devices that are built using these nanomaterials are, therefore, capable of deriving new or enhanced functionalities based on the remarkable optical, chemical, thermal, magnetic, and transport properties accessible. Nanomaterial fabrication involves various methods and strategies for synthesizing, manufacturing, and assembling nanostructured surfaces and nanostructures.

PhD Candidate Samantha K. Ratley - "The Hemodynamic Theory of Bicuspid Aortic Valve Disease"
The bicuspid aortic valve (BAV) is the most common congenital cardiovascular defect affecting 1-2% of the population. A normal aortic valve consists of three leaflets and is often referred to as the tricuspid aortic valve (TAV). The BAV exists in several different morphogenic phenotypes, resulting in two aortic valve leaflets instead of three and is known as the type-I BAV.

PhD Candidate Piyush Ranade - "Turbulence Amplitude Modulation in an Externally Forced Turbulent Boundary Layer"
The research presented in this dissertation describes an experimental investigation of an externally forced, high-Mach-number, subsonic turbulent boundary layer. The experimental study was motivated by the results of a previous experiment using wavefront data obtained by passing a laser through a high-Mach-number, regularized shear layer. While the results clearly showed that the wavefronts due to the shear layer were regularly repeated, there appeared to be synchronized turbulent “bursts” in the high-speed turbulent boundary layer on the wall of the shear-layer facility.

PhD Candidate Jesse M. Coffman - "Wake Orientation And Its Influence On The Performance Of Diffusers With Inlet Distortion"
Distortion at the inlet to diffusers is very common in internal flow applications. Inlet velocity distortion influences the pressure recovery and flow regimes of diffusers. This work introduced a centerline wake at the square inlet of a plane wall diffuser in two orthogonal orientations to investigate its influence on the diffuser performance. Two different wakes were generated.

PhD Candidate Travis L. Brown - "Reaction Wheel Actuation for Stabilization and Efficiency Improvement in Planar Bipeds"
As robotic technology moves out of factories and into broader segments of society, it promises to support a revolutionary improvement in the general standard of living. One of the largest hurdles to this increased use of robotic technology, however, is the inability of current mobile robots to negotiate difficult and delicate terrain in ways that are fast, efficient, and safe.

BioPhD Candidate Lisa E. Cole - "Bisphosphonate-Functionalized Gold Nanoparticles as a Targeted X-Ray Contrast Agent for Breast Microcalcifications"
Breast cancer is the most common cancer and the second leading cause of cancer- related deaths among women. Early detection is considered the best option for reducing morbidity and mammography is the current gold standard for early detection of breast cancer. Microcalcifications are the most common abnormality observed on a mammogram and are early markers for breast cancer.

PhD Candidate Peter Sutcliffe - "Neural Network Feedforward Control of a Closed-Circuit Wind Tunnel"
Accurate control of wind-tunnel test conditions can be dramatically enhanced using feedforward control architectures which allow operating conditions to be maintained at a desired setpoint through the use of mathematical models as the primary source of prediction. However, as the desired accuracy of the feedforward prediction increases, the model complexity also increases, so that an ever increasing computational load is incurred.

PhD Candidate Andrew P. Baumann - "The Relative Influence of Material and Architectural Properties on the Mechanical Behavior of Bone Tissue"
Bone tissue exhibits a unique multiscale hierarchical composite structure. The material, or extracellular matrix, constituent phases of water, collagen, and apatite bone mineral are organized and preferentially oriented over several length scales to optimally bear and distribute mechanical loads in the skeleton. At larger length scales, the architecture of bone is continually remodeled through the creation of pore space and deposition of new tissue.

PhD Candidate W. Robert Burns - "Statistical Learning Methods for Aero-Optic Wavefront Prediction and Adaptive-Optic Latency Compensation"
Since the early 1970’s research in airborne laser systems has been the subject of continued interest. Notable airborne laser demonstration programs include the Airborne Laser Laboratory, ALL, the Airborne Tactical Laser, ATL, and the Airborne Laser, ABL. In the mid-1990’s researchers also began studying airborne free-space communication systems. Both of these applications depend on being able to propagate a near diffraction- limited laser beam from an airborne platform, but the realization that the airflow over the beam directors can destroy the quality of the laser beam is relatively recent.
