I provide customer service and technical support for the PRISM Imaging and Analysis center, train new users and assist current users in the proper operation and technical aspects of equipment in the center.

Paul Shao, Imaging & Analysis Specialist
075 Andlinger Center, 609-258-3851

I am a soft materials (biological) and cryo-imaging specialist. I help provide customer service, training and technical support for imaging and sample preparation equipment at the PRISM Imaging and Analysis Center.

Conrad Silvestre

Conrad Silvestre, Chemical Hygiene Officer
155 Andlinger Center, 609-258-6236

I manage C402/404/406/408/422 labs, conduct maintenance and training on PRISM Clean Room Tystar, Thermco, RCA Wet Bench, and Gas Alarm System. I also assist in Clean Room management.

Deborah L. Sivco, Engineer-in-Residence
215 Bowen Hall, 609-258-1717

I am responsible for the Molecular Beam Epitaxy (MBE) growth of GaInAs/AlInAs Quantum Cascade laser structures at Princeton University. This includes maintenance of the Molecular Beam Epitaxy lab in Bowen 203, as well as optimizing growth of many layered semiconductor heterostructures. Wafers from my lab are used by collaborators across MIRTHE and PRISM.

Ken West

Ken West, Research Specialist
C432 E-Quad, 609-258-4638

I have primary responsibility for MBE growth of GaAS structures for 2-DEG systems and optical devices using our ultra high mobility MBE machine. Responsibilities include: maintenance of the MBE equipment, high vacuum systems and design innovations aimed at improving the quality of the MBE structures.
