Yi Lu is the Jay and Ann Schenck Professor of Chemistry at the University of Illinois
at Urbana-Champaign. He received his BS. degree from Peking University in 1986, and
PhD. degree from University of California at Los Angeles in 1992 under Professor Joan S.
Valentine. After two years of postdoctoral research in Professor Harry B. Gray‘s group at the
> ., - . California Institute of Technology, Dr. Lu started his own independent career in the Depart—
‘T‘MT'T'T'W 3‘ T“: ' ment of Chemistry at the University of Illinois at Urbana—Champaign in 1994. He is now the
.» ._ ‘X Jay and Ann Schenck Endowed Professor of Chemistry and HHMI Professor in the Depart—
ments of Chemistry, Biochemistry, Bioengineering and Materials Science and Engineering.
a He is also a member of the Center for Biophysics and Computational Biology and the Beck-
1 ‘ man Institute for Advanced Science and Technology. His research interests lie at the inter-
, ‘ face between chemistry and biology. His group is developing new chemical approaches to
' I provide deeper insight into biological systems. At the same time, they take advantage of
,_ ‘=. recently developed biological tools to advance many areas in chemistry. Specific areas of
current interests include a) design and engineering of functional metalloproteins as environ-
* mentally benign catalysts in renewable energy generation and pharmaceuticals; b) Funda—
mental understanding of DNAzymes and their applications in environmental monitoring, medical diagnostics, and target—
ed drug delivery; and c) Employing principles from biology for directed assembly of nanomaterials and its applications in
photonics and sensing. Dr. Lu has received numerous research and teaching awards, including the Fellow of the Ameri—
can Association for the Advancement of Science (2007), Early Career Award, Society of Biological Inorganic Chemistry
(2007), Howard Hughes Medical Institute Professor Award (2002), Camile Dreyfus Teacher-Scholar Award (1999), AI—
fred P. Sloan Research Fellowship (1998), Research Corporation Cottrell Scholars Award (1997), and the Beckman
Young Investigators Award (1996).
. E. " ., . Harry Gray is the Arnold O. Beckman Professor of Chemistry and the Founding Direc-
‘ 1’» ~. 3;. ’ . ,“ tor of the Beckman Institute at the California Institute of Technology. He received his
.‘3 EM V- _. _‘ )3 BS. degree from Western Kentucky University in 1957. After graduate work at Northwest-
5 rh- _;_( Ligfifga ern University and postdoctoral research at the University of Copenhagen, he joined the
. é 4* Xi ‘11. chemistry faculty at Columbia University, where in the early 1960s he developed ligand field
., gr. ' theory to interpret the electronic structures and substitution reactions of metal complexes.
’1 After moving to Caltech in 1966, he began work in biological inorganic chemistry and solar
J photochemistry, including the development of inorganic systems for energy storage. Work-
' ' “"“"“"“ "“’ " “ ‘ ing With Ru-modified proteins in the early 19805, he demonstrated that electrons can tunnel
rapidly over long molecular distances through folded polypeptide structures; and, in the
years following, he and J. R. Winkler developed laser flash-quench methods that opened the
, way for experimental investigations that have led to a deeper understanding of the mecha—
' ‘ - nisms of electron flow through proteins that function in respiration and photosynthesis. Dr.
Gray has published over 800 research papers and 18 books. He has received the National Medal of Science from Pres-
ident Ronald Reagan (1986); the Pauling Medal (1986); the Linderstrom-Lang Prize (1992); the Gibbs Medal (1992);
the Harvey Prize (2000); the National Academy of Sciences Award in Chemical Sciences (2003); the Benjamin Franklin
Medal in Chemistry (2004); the Wolf Prize in Chemistry (2004); the City of Florence Prize in Molecular Sciences (2006);
the Welch Award(2009), the Priestley Medal (1991); and 16 honorary doctorates, including ones from Rochester, North-
western, Pennsylvania, Chicago, Columbia, Toulouse, Florence, Copenhagen, and Edinburgh. He is a member of the
National Academy of Sciences; the American Academy of Arts and Sciences; the American Philosophical Society; a
foreign member of the Royal Danish Academy of Sciences and Letters; the Royal Swedish Academy of Sciences; the
Royal Society of Great Britain; and the Accademia Nazionale dei Lincei. He has been a member of the Board of Direc-
tors of the Arnold and Mabel Beckman Foundation since 1994.
