Dr. Essink specializes in structural dynamics with a focus in mechanical vibration. She has extensive experience in vibration testing and analysis using both experimental and theoretical frameworks to solve engineering problems. Her experience includes analytical, finite element analysis (FEA), and experimental validation and verification. She has performed modal analysis using shaker tables and impact hammers. She has also developed custom instrumentation systems for diverse structural dynamics problems. Dr. Essink also has broad experience with mechanical characterization of material properties, including their vibration mitigation properties. Her mechanical characterization tests have relied on servo-hydraulic load frames for moderate loading rates and Split-Hopkinson Pressure Bar (SHPB) systems for high loading rates. She has conducted additional material characterization using X-ray powder diffraction (XRD) and thermal chamber testing.

At the University of Michigan, Dr. Essink studied vibration mitigation using mechanical metamaterials, or metastructures, capable of vibration attenuation under multi-axial excitation. She additionally studied compact piezoelectric energy harvesting modules using zigzag shaped structures with magnetically-induced nonlinearity. At Purdue University, Dr. Essink studied the blast-mitigation properties of geological materials. Her internships at JPL focused on the Soil Moisture Active Passive (SMAP) satellite. She verified SMAP’s software for its response to simulated faults and verified design calculations for SMAP’s reaction wheels. She also verified solenoids for use on the solar arrays by exposing them to thermal chamber environments. At Florida Institute of Technology, Dr. Essink’s research included wiring and coding the electronics on a lunar lander robot for both operation and communication. She additionally worked on liquid slosh in fuel tanks culminating in a ride on NASA’s zero gravity “Vomit Comet” flight to further understand the dynamics of liquid rocket fuel in microgravity environments.
