3D printing of Fiber-Reinforced Ultra-High Temperature Ceramics for Hypersonic Applications​
3D printing of ultra high temperature ceramic Zirconium Diboride (ZrB2) with polymer derived ceramic and Silicon Carbide (SiC) short fiber and continuous Carbon Fiber (CF), developing pyrolization schedule to achieve highest possible flexural strength from the 3D printed parts for hypersonic application.
Functional Graded Ultra High Temperature Ceramics for Hypersonic Applications
The purpose is to utilize the oxidation resistance Zirconium Diboride (ZrB2) offers while simultaneously reducing the waste and cost by incorporating Silicon Carbide (SiC) in a heterogenous design. This design will ensure a strong interface between the materials and could potential reduce the weight and cost of aerospace vehicles.

Fabrication of Templated Grain Growth Ceramic Composites of Barium Titanate Oxide (BaTiO3) and Sodium Niobate Oxide (NaNbO3)
This research evaluates Barium Titanate (BaTiO3) as a safer alternative to lead-based piezoelectrics, using additive manufacturing to enhance its properties by texturing with platelet-shaped particles. Findings show that tailored grain orientation significantly boosts BaTiO3's dielectric performance, offering a promising advance in non-toxic piezoelectric ceramics.

Utilizing topology optimization to create ceramic lattices with tunable Mechanical and Thermal Properties
Here, the high resolution of DLP technology is used to fabricate detailed ceramic lattices that result in unique thermal and mechanical properties. Based on previous literature, lattice type, size, and thickness are being manipulated in order to see the effect on thermal conductivity of ceramics. Mechanical properties are being enhanced by implementing gradient thickness, altering the lattice type, and introducing epoxy fillings and coatings.
