EDUCATION:
University of Michigan, Ann Arbor, MI

Ph.D. Electrical Engineering – MEMS – May 2019

 
University of Louisville, Louisville, KY

MEng Electrical Engineering – May 2014                          

 

BS Electrical Engineering – August 2013

 
EXPERIENCE:
Fall 2015                             

Ph.D. Research, Lurie Nanofabrication Facility (LNF), University of Michigan

Harsh Environment Wireless Pressure Sensor

Refined a microfabrication process flow to be used as a prototyping platform for lower-cost creation of MEMS devices.  Research focused on creating a robust, high-yield process flow allowing for multiple devices to be simultaneously fabricated.  Example devices fabricated include self-sealed pressure sensors for harsh environments, device-level packaged RF switches, geolocation hydrophone arrays, and a wireless device for short range communication with inductive coupling. 

 

Summer 2013                      

Research Assistant, Micro-Nano Technology Center, Speed School of Engineering, ECE Department

Germanium on Silicon Integrated Photodiode

Developed processes in a cleanroom environment to study the variation of electrical properties and viable etchants on electron beam (e-beam) and physical vapor deposition (PVD) deposited germanium (Ge) thin films on silicon substrates. Successfully developed methods for processing and etching these thin films. These findings were published in the SPIE (International Society for Optics and Photonics) Proceedings in October 2014. This data was then used to develop and fabricate a Ge-based photo-diode on a silicon substrate for complete integrated circuit integration with communication technology.

Spring 2013                         

MEMS Bistable Temperature Sensor

Lead a team of two electrical engineering students to design and develop a miniaturized commercial bistable temperature sensor by using MEMS technology. Fabrication duties included photolithographic process development, deposition of thin films, and polymer bonding. Project was successful and resulted in a follow-on contract from the customer (Raytheon).  Project documentation included creation of System Requirements and Spec Documents for customer.

Spring 2013                         

Analog Integrated Circuit Design and Testing

Studied design processes and layout techniques of analog integrated circuits, culminating in the design of a temperature-independent bandgap voltage reference and regulator.  After the voltage regulator was designed and tested in SPICE, it was laid out in L-Edit, where all components were created from scratch.  The design was fabricated by MOSIS and found to be successful when tested.

Fall 2012                             

Piezoresistive Pressure-Sensor Process Development

Studied microfabrication techniques and design software for creating MEMS devices. A piezoresistive pressure sensor was fabricated in the Louisville MNTC Cleanroom. The device was then diced, packaged and successfully tested.

 
OTHER EXPERIENCE:

Fall 2010 - Fall 2013                             

DoE Solar Decathlon House

Lead a team of five junior and senior level electrical engineers to design all electrical requirements of a low-cost, solar-powered disaster relief housing option.  Competed against international teams in the DoE Solar competition in Irvine, CA in fall of 2013.
