Dr. Ryan Seifert’s research focuses on the design and analysis of advanced composite materials, particularly those with locally tailored properties. Using tools like Multifunctional Topology Optimization, Composite Damage Mechanics, and ML/AI, his work primarily involves optimization of locally tailored materials, such as those created via additive manufacturing or Tailored Fiber Placement.

In addition to gradient-based topology optimization routines, Dr. Seifert has also developed several genetic algorithms that utilize UDRI’s BSAM finite element and damage evolution software. He also created a K-NN clustering scheme for composite damage characterization via Acoustic Emission (AE) waveform analysis.
