Xu
Wins NIH Grant
Dr. Xiaoming Xu, director
of biomaterials research,
has achieved a major
milestone in his research
career with the award of a
R01 grant from the
National Institutes of
Health (NIH) in the amount
of $1.77 million over four
years. He has been with
the LSU School of
Dentistry since 1995 and
is currently associate
professor in the
Department of
Comprehensive Dentistry
& Biomaterials.
The purpose of this
research project is to
develop dental materials
with fluoride-releasing
and antibacterial
properties. "The
development of these
materials has the
potential to make a huge
impact on oral health care
and oral health quality of
life," he said. "This is
especially true for
vulnerable populations
like children, the
elderly, those who suffer
from dry mouth and those
who are mentally or
physically challenged."
To appreciate the
significance of this
award, it's important to
note that the NIH
currently funds only 18
out of every 100
applications, according to
Dr. Paul Fidel, director
of the Center of
Excellence in Oral and
Craniofacial Biology.
"Competition for these
grants is fierce," he
said. "Some of most
accomplished scientists in
America carefully review
each application. Dr. Xu
had to compellingly prove
that his work is
significant and
innovative. Also, that he
has a supportive
environment and a track
record for getting his
work done."
Dr. Xu was a junior
principal investigator
under the NIH-COBRE
mentoring grant of Dr.
Paul Fidel. The objective
of that grant has been
fulfilled as he evolved to
the status of independent
researcher, as evidenced
by the awarding of the R01
grant.
Dr. Xu's track record
since Hurricane Katrina
speaks volumes about
facing the setbacks of
life. Shortly after the
storm, he persuaded the
Joe W. and Dorothy Dorsett
Brown Foundation of
Metairie to award him
$300,000 as seed money for
equipment replacement
while negotiations with
FEMA took place. This
grant helped in the
rebuilding of the
biomaterials laboratory,
which suffered major
damage from Katrina.
In 2007, Dr. Xu obtained
another grant from the
Brown Foundation for
$492,192 over three years.
The objective of this
project is to develop new
technology for producing
novel functional polymer
nanofibers for biomedical
applications.
His fourth major grant
since Katrina was an
earlier R21 grant, also
from the NIH. The grant
was for $525,000 over
three years. Last year,
the NIH funded only 16% of
all R21 applicants. The
purpose of this project is
to develop zirconia
ceramic nanofibers and
nanofiber-reinforced
dental composites, which
will be much stronger and
tougher than current
materials.
Dr. Xu started his
research career at LSUSD
in 1995 as research
associate and joined the
faculty in 2001. Over the
past 14 years, he has
mentored 60 students,
residents and postdoctoral
research associates who
conducted research in the
biomaterials laboratory.
He has authored or
co-authored 120
publications, including
journal articles, book
chapters, meeting
proceedings and abstracts.
He has received two U.S.
patents and has four
patent applications
pending.
