Brief Vita of James Oxley

Biographical Sketch
James G. Oxley was born in Australia. Since 1986, he has been a permanent resident of the United States.
He received his undergraduate education in Australia and his Ph.D.
from the University of Oxford in 1978 under the supervision of D.J.A. Welsh.
Before joining the faculty of Louisiana State University as an Assistant
Professor in 1982, he was a Lecturing/Research Fellow at the Australian
National University for three years, and a Fulbright Postdoctoral Fellow
at the University of North Carolina for one year.
At LSU, he was promoted to Associate Professor in 1985,
to Professor in 1990, and to Alumni Professor in 1999.
He was the principal organizer of the TwentySecond, TwentySeventh, and ThirtySecond
Southeastern International Conferences on Combinatorics, Graph Theory and
Computing which were held in Baton Rouge in 1991, 1996, and 2001.
He has written over one hundred papers in matroid theory and graph theory,
given more than fifty conference talks, and written
a book on matroid theory.
In 1995, as one of the four principal speakers at the
AMS/IMS/SIAM Joint Summer Research Conference, Matroid Theory,
he spoke on Structure theory and connectivity for matroids and,
with Joseph E. Bonin and Brigitte Servatius, edited the proceedings
of that conference. In 1999, he was named LSU's Distinguished Research Master for
Engineering, Science, and Technology. In 2001, he was one of the nine principal speakers
at the Eighteenth British Combinatorial Conference, and in March, 2002, he
presented an invited onehour address to the American Mathematical Society meeting
in Atlanta. From April until July, 2005, he was a Visiting Research Fellow at Merton College, Oxford. He is the matroid theory editor for
Combinatorics, Probability and Computing and is on the editorial boards for the
Journal of Combinatorial Theory Series B and for the SIAM Journal on Discrete
Mathematics. He directed the building of the current LSU combinatorics group, Guoli Ding, Bogdan Oporowski, and Dirk Vertigan. The four members of this group have received eighteen individual federal research grants since 1994. In particular, Oxley has had continuous support since then from the National Security Agency. Twelve students have completed Ph.D.'s under Oxley's direction and he is currently advising two other students. Oxley's research collaborators, Geoff Whittle, Manoel Lemos, and Charles Semple, have made frequent extended research trips to LSU and, since 2000, each of Luis Goddyn and Criel Merino has visited the combinatorics group for at least a semester.
