Welcome to my website! This site primarily serves to document and present the major projects that I have been privileged to work on as an engineer. By publishing my designs and methodologies on the web I aim to both spur dialogue and share knowledge with other engineers and students. Please feel free to e-mail me about anything you find interesting on this site at moc.l1563378140iamg@1563378140renne1563378140uda1563378140.
Passive Wafer AlignmentI designed, fabricated, and evaluated this device to passively align 100mm wafers on a metrology stage. Three pins constrain the wafer and a flexure applies a nesting force. The design focused on optimizing pin locations for optimum positioning repeatability.
2015 ASPE Student Competition2015 ASPE Student Design Competitio. Congratulations, team on winning first place!
AFM Z-Axis Auto ApproachA mechanical system consisting of a voice coil actuator fixed to a flexural bearing provides sub-micron positioning resolution over a 1-mm range and allows automated approach for an AFM metrology system.
