Hollis Whittington
Doctoral Alumnus
EDUCATION:
- BS Electrical Engineering, North
Carolina State University, 1998
- MS Electrical Engineering,
Stanford University, 2002
- PhD Electrical Engineering,
Stanford University, 2006
WORK EXPERIENCE:
- 2007-present:
Staff
member of the Applied Research group at Micro Systems Engineering, a Biotronik
company. I specialize in the development of technologies for closed-loop
control of pacing parameters in pacemakers and defibrillators. I also
work to design, develop, and test new concepts and algorithms for
cardiac rhythm management.
- 2006-2007: Post-doctoral researcher,
Stanford University, pursuing technologies for co-culture of
electrically-active cells on microelectrode arrays
- 2000-2006: Research Assistant,
Doctoral Candidate, Stanford University
- 1998-2000:
MIT Lincoln Laboratory, Analog Device Technology - Contributed to
several projects, including: circuit design of CCD-based A/D converters
for ultra low-power applications, design of single-chip CCD imager and
A/D converter, design of digital correlator in Lincoln Laboratory SOI
process, cryogenic analysis of SOI CMOS.
- 1997-1998:
Undergraduate Research Fellow in Electrical Engineering at North
Carolina State University. Research centered in fabrication facilities
on fabrication of test structures for thin gate oxides <20 Angstroms
and development of characterization procedures for thin oxides.
