The People of Data Understanding Systems
 |
Kenneth Hurst
|
Group Supervisor
Kenneth Hurst graduated in 1980 from Earlham College in Richmond,
Indiana, where he double majored in Geology and Physics. He went
on to graduate school at Lamont-Doherty Geological Observatory of
Columbia University in New York, earning a Masters in 1982, and a
Ph.D. in Geology in 1987. The title of his Ph.D. thesis was "The
Measurement of Vertical Crustal Deformation." His advisors were
Roger Bilham and Paul Richards. After a post-doc at Lamont, he
came to JPL in 1990 to work on development of Global Positioning
System (GPS) analysis methods for measuring crustal deformation.
In 1996 he received the NASA Award for Excellence, and in 2004
he was inducted into the Space Technology Hall of Fame for this
work. In 2001 he became the Group Supervisor for the Data
Understanding Systems group. In 2005 he re-entered graduate school
at the University of Southern California in pursuit of a Masters
in Systems Engineering and Systems Architecture. Ken's professional
interests span solid Earth geophysics, machine learning, and space
mission design.

Mike Turmon
|
Principal Engineer
Mike Turmon graduated in 1987 from Washington University in St.
Louis, receiving bachelor's degrees in Computer Science and in
Electrical Engineering. He went on to get a Ph.D. in Electrical
Engineering from Cornell University in 1995, with an emphasis on
probabilistic theories of learning in neural networks. He came to JPL
thereafter, joining the MLS group and later the DUS group. He
received the Presidential Early Career Award for Scientists and
Engineers (PECASE) in 2000. Michael's research interests include
pattern recognition, object tracking, maximum-likelihood estimation,
and clustering, with applications in object time series and solar
image analysis.

Jeff Jewell
|
Senior Member, Information Systems and Computer Science Staff
Jeff Jewell received his Ph.D. in Astrophysics from the University
of Chicago in 2000. He was an NRC Post-Doc at JPL from 2000-2001,
and in 2001 became a member of the Senior Level Staff in Information
Systems and Computer Science.
His research interests are in Bayesian inference for large data sets,
inverse problems, dynamical systems, and spatial random fields.

Greg Lyzenga
|
Senior Member, Information Systems and Computer Science Staff
Greg received his B.S. in Physics from Harvey Mudd College in 1975. He
earned his M.S. and Ph.D. degrees in Applied Physics from Caltech in
1977 and 1980 respectively. He became a JPL staff member in 1980,
continuing to the present. In 1990 he became a professor of Physics at
Harvey Mudd College, where in addition to teaching a wide array of
undergraduate physics courses, he carries out geophysical research
using both numerical and GPS geodetic methods.

Robert Granat
|
Senior Member, Information Systems and Computer Science Staff
Robert Granat graduated from the California Institute of Technology
in 1996 with a B.S. in Computation and Neural Systems. He received
M.S. and Ph.D. degrees in Electrical Engineering from the University
of California, Los Angeles in 1998 and 2004, respectively. His research interests include statistical pattern recognition, particularly as
applied to time series data, imaging systems, and fault-tolerant
computing.

Amy Braverman
|
Senior Member, Information Systems and Computer Science Staff
Amy Braverman holds B.A. in Economics from Swarthmore College (1982),
an M.A. in Mathematics from UCLA (1992), and a Ph.D. in Statistics
from UCLA (1999). She was a Caltech Post-doctoral Scholar at JPL for
two years before joining the Earth and Space Sciences Division as a
Scientist. She is the Level 3 Scientist for the Multi-angle Imaging
SpectroRadiometer (MISR) mission, and a member of the Level 3
Science Integration Team for the Atmospheric Infrared Sounder
mission. In June 2004 she joined the Data Understanding Systems Group
though she maintains her positions and roles in the MISR and AIRS
projects. Dr. Braverman's research interests are in applications of
data compression and information theoretic methods to the analysis
of massive data sets and streams, statistical methods for climate
model evaluation, data fusion, and visualization. She is the
President of the Interface Foundation of North America, and is a
member of the Committee on Applied and Theoretical Statistics, Board
on Mathematical Sciences, of the the National Academy of Science.

Tim Stough
|
Member, Information Systems and Computer Science Staff
Tim Stough Granat received both is B.S. and M.S. degrees in Electrical and Computer
Engineering from Purdue University in 1994 and 1997. His research interest is in
computer vision.
