- Three chemistry majors are among four Duke students to win prestigious
Goldwater Scholarships.
Duke's newest Goldwater Scholars are Joseph
Babcock, Brandon Levin and Felicia Walton, all
juniors, and Jonathan Russell, a sophomore.
Sixty-two Duke students have received Goldwater
Scholarships since the program was initiated in 1988.
Joseph Babcock, a junior from North Haven,
Connecticut, is majoring in biology and chemistry
and anticipates a career as a biochemist. His
current research in the Department of Biochemistry
with Dr. Arno Greenleaf focuses on the regulation
of gene expression in simple organisms. Joseph
plans to dedicate his science career to the study
of how biochemical pathways regulate the
development of parasites responsible for tropical
diseases such as malaria. In addition to his
research, Joseph serves in editor positions with
Vertices, Duke's journal of science and
technology, and The Blind Spot, Duke's sci-fi
literary magazine.
Brandon Levin, a junior majoring in mathematics,
is from Toledo, Ohio. He plans to pursue a career
in research in pure mathematics and is especially
interested in number theory. "While chemists or
physicists look at a molecule or an electron and
try to determine its fundamental structure, number
theorists want to understand the structure of the
integers," said Brandon who was a 2005 PRUV Fellow
in the Department of Mathematics with Dr. Les
Saper. Brandon has been a counselor and lecturer
at PROMYS, Program in Mathematics for Young
Scientists, in Boston and serves as an ESL teacher
in the Durham community.
Jonathan Russell, a sophomore from Iowa, is
majoring in biology and chemistry. Following
graduation from Duke, he expects to earn a dual
M.D./Ph.D. degree followed by a career as a
molecular geneticist in an academic medical
center. In Dr. Alejandro Abally's laboratory in
the Department of Molecular Genetics and
Microbiology, Jonathan is studying the mechanism
of action and synthesis of antimicrobial peptides
in simple animal systems. Jonathan is a
co-founder and president of Students for Organ
Donation and is a member of the First Year
Advisory Council.
Felicia Walton, a junior from Asheville, North
Carolina, has been engaged in research since her
first year at Duke. Majoring in biology and
chemistry, she has been exploring the genetics of
pathogenic fungi, the subject of two published
papers she recently co-authored with her mentors,
Dr. Joseph Heitman and Dr. Alexander Idnurm in the
Department of Molecular Genetics and Microbiology.
Felicia is the current President of the Biology
Majors Union and a volunteer biology tutor with
the Duke-Durham Partners for Youth.
According to the Goldwater Foundation, "Goldwater
Scholars have very impressive academic
qualifications that have garnered the attention of
prestigious post-graduate fellowship programs.
Each of Duke's 2006 Rhodes Scholars were also
Goldwater Scholars. The Foundation's announcement
and list of Scholars can be found at
. - We are pleased to welcome Prof.
Dewey McCafferty who is joining the Department
of Chemistry as a Full Professor. Dr. McCafferty's
research interests are broadly based in chemical
biology and molecular medicine. His group
utilizes techniques in organic synthesis,
mechanistic enzymology, molecular biology, and
rational protein design to produce novel small
molecule and peptide-based ligands which they use
to characterize, modulate, and inhibit enzymic
processes which have an immediate and direct
therapeutic relationship to human disease.
- Julianne Yost and Guoqiang Zhou of the Coltart
group have recently reported a novel method for conducting the
direct aldol reaction, one of the most important
carbon–carbon bond- forming reactions known. Their
process relies on the use of simple thioesters –
substrates that Nature routinely uses for
carbon–carbon bond formation – and is advantageous
in its mildness, simplicity, economy and low
environmental impact.
- Senli Guo and Boris Akhremitchev have observed, using atomic force microscopy, structural heterogeneity in amyloid fibrils. Their work has direct implications for the structural study of fibril-forming proteins, implicated in a wide range of human neurological diseases.
- Graduate student Farrell Kersey and co-workers from the Craig group have observed bimolecular reactions occurring
one at a time using single molecule force
spectroscopy. When the bond being broken is
mechanically "spring loaded", the rate of the
reaction (which involves another bond being
formed) increases. The researchers observe that
two different but related reactions respond to
force in pretty much the same way--that is, the
mechanism of the reactions is reflected in the
mechanics of the single molecules.
- Summer research opportunities for Duke undergraduates are now available.
Interested students should submit an application
by March 10.
- An exciting breakthrough in computational theory has just been published by Xiangqian
Hu, Prof.
David Beratan, and Prof.
Weitao Yang. Using linear combinations of
atomic potentials, the group demonstrates how
molecular structure within a staggering and vast
universe of possible molecules can be rapidly
optimized to a particular function. The new
method was applied to molecular
hyperpolarizability, but it could one day be
extended to problems ranging from drug design to
electronic devices.
- Xiaoqing Han and Ross Widenhoefer have recently reported an important step in the
development of catalytic
hydroamination. Their Au(I)-catalyzed protocol
allows the intramolecular hydroamination of
unactivated olefins under milder conditions and
with broader substrate scope than was previously
realized with late transition- metal catalyst systems.
- The Fitzgerald Group's recent findings about the conserved thermodynamics
of hydrogen bonds in protein folding reactions
were reported last week in PNAS
and highlighed in a recent Duke
News Release.
- New research conducted in labs from several departments at
Duke, including that of Thom
LaBean in Chemistry, has led to the
hierarchical assembly of finite, fully-
addressable nanoscale lattices.
- An interdisciplinary cross-department and cross-school team of Duke chemists,
biochemists, mathematicians, and computer
scientists has
solved a key protein-protein docking problem. The
project is
highlighted in a recent issue of Duke
Dialogue.
- Professor Charles Lochmüller will be receiving the Distinguished Service Award
from the Center
for Biomolecular and Tissue Engineering at
this year’s CBTE Awards Dinner on the evening of
April 19th, 2006 at the CIEMAS Atrium.
Professor Lochmüller is retiring from Duke after
almost 37 years of service. When he served as
Chair of the Chemistry Department, he was part of
the small group lead by Professor Clark that
created what became the Center for Biochemical
Engineering [now the Center for Biomolecular and
Tissue Engineering], was Professor of Biochemical
