Development and the system-level packaging of chemical analysis systems and components. Moorman has lead the system and sensor design portions of DARPA (Defense Advanced Research Projects Agency), DTRA (Defense Threat Reduction Agency), and Sandia-funded chemical analysis programs. His recent work has focused on detecting and characterizing the volatile organic compounds (VOC) produced by bacteria, plants, and algae.
Bachelor’s Degree: Physics, Kalamazoo College (1994-1998)
Master’s Degree: Mechanical Engineering, Georgia Institute of Technology (1999-2001)
Moorman’s undergraduate field of study was in physics with a focus on engineering as he moved to graduate studies. His Master’s thesis work focused on the development of a microfabricated Kelvin probe for surface studies.
Modeling and Fabrication of Micro-Hotplates and Other Miniaturized MEMS Thermal Structures
Moorman has developed a variety of MEMS thermal structures for purposes as diverse as chemical preconcentration, catalytic decomposition, on-demand material evaporation, sensing, and valve actuation for microfluidic and miniaturized sampling systems. These thermal structures are modeled using finite element modeling code such as ANSYS and are then produced using microfabrication or meso-scale manufacturing techniques. He has experience developing and using novel oxides and metal formulations to allow structures to survive elevated temperatures for extended time periods, including some designs that can reach over 1000 ºC
Microfluidic Systems for Biological Analysis
Moorman has created PDMS, plastic laminate, and silicon-based microfluidic structures for many different biology applications including single cell capture and isolation, bio-sensors, and pneumatic cell-sorters. He has also created structures with optimized optical interfaces for hyperspectral imaging and microscopy of single cells and proteins. To support further miniaturization efforts, he has also created several novel valve structures that can be easily integrated into these microfluidic systems to enable fluid control at the chip level.
Design and Fabrication of Chemical Sensors and Chemical Analysis Systems
Continued development of Sandia’s MicroChemlab system and its associated technologies has been another technical focus area for Moorman’s research. He has helped design and mature several key technologies such as high-aspect ratio gas chromatography columns (GC), tortuous path preconcentrators, and novel UV-plasma detector technologies. Moorman designs and develops fabrication process flows for these components as well as strategies for system-level integration and packaging. Recent work has focused on developing wafer-level coating and packaging processes to alleviate the labor-intensive steps required in prior-generation fabrication processes, as well as developing new system-level approaches to microGC separations of complex mixtures.
