In Step With Xinfei Guo
Feeling at Home With the IEEE Solid-State Circuits Society
W
Whether you're a young professional
or have been an IEEE Solid-State
Circuits Society (SSCS) member for
decades, you've probably attended
an SSCS Young Professionals webinar,
participated in a mentoring event,
or joined the online mentoring platform.
Xinfei Guo is one of the young
and vibrant forces behind the SSCS
Young Professionals.
Xinfei is an assistant professor at
the University of Michigan-Shanghai
Jiao Tong University Joint Institute,
Shanghai Jian Tong University, China.
His research interests include the
areas of electronic design automation,
reliable and low-power system design,
and hardware acceleration techniques.
Before returning to academia, Xinfei
spent almost 11 years studying and
working in the United States, employed
a senior engineer at Nvidia. Xinfei's
dissertation work was to resolve chip
aging issues, a topic that has been
gaining increased attention in recent
years. His focus was to look at solutions
that can fully recover the chip
from aging.
" Before this project, I viewed
myself more like a circuit designer.
I wasn't exposed to much in device
physics, computer architecture, or
software, " Xinfei said. " After working
on this project, I was able to expand
my research scope into a much wider
field, in which I looked at cross-layer
design solutions that work together to
cope with aging issues. "

category. I view the interdisciplinary
approach a catalyst for pushing
the boundary of any research. "
Xinfei looks forward to educating
the next generation of circuit designers
and researchers. " The moment my
students get recognized and accomplish
their dreams will be my next
biggest achievement, " he said.
The SSCS has greatly impacted Xinfei's
life in many aspects beyond just
his work and career. It was the first
IEEE Society he joined and the only
Society he has stayed with throughXinfei
gives a talk at a conference.
Xinfei was conducting the measurement
of aging with real silicon, and
he observed unique recovery behaviors
that were not discovered before.
He commented that it felt like he was
revealing unknowns that, potentially,
could truly impact the field.
This is the moment
that Xinfei
credits with triggering his interest in
the field. It pushed him to take a deep
dive into detailed physics and leverage
his circuit design experience
to come up with a whole set of onchip
design solutions, which he later
expanded to higher levels of abstractions,
including the architecture and
system levels. Xinfei and his advisor,
Prof. Mircea Stan, wrote a full book
on this topic.
" This experience opened a new
door for me to look at my research
from multiple perspectives, " Xinfei
said. " Even in my current research,
I never limit myself into one single

out the years.
" The Society is truly like a family
where you make long-lasting friendships, "
Xinfei said. " Our Society cares
about its members, and our members
give back to this family as they grow. "
As a new person in the field, Xinfei
had the opportunity to meet many luminaries
in the Society, including textbook
authors, famous professors, and
well-known researchers-all through
involvement with various SSCS activities.
The Society provided Xinfei with
a channel to reach out to colleagues
from all around the world.
" I have learned so many things from
SSCS webinars, talks given at conferences,
and casual conversations, " Xinfei
said. " Being an SSCS member is the
best way for me to learn about cuttingedge
research and technology in the
solid-state circuits field and beyond. "
SSCS membership has helped him
shape his research direction and gain
awareness of the field.
A few years ago, Xinfei received a
small token that congratulated him for
