Narrative
I started my professional career as a graduate student in the
Department of Astronomy at Boston University where I worked with
Professors Theodore Fritz and Harlan Spence on magnetospheric physics,
instrumentation, and data analysis problems. I was involved in the
testing and commissioning of instruments for the NASA Polar spacecraft
as well as for the ESA Cluster spacecraft, in Boston (flight detector
testing), at Goddard Space Flight Center (pre-launch testing), at the
Polar spacecraft contractor's facility in New Jersey (thermal vacuum
testing), and at the ESA launch facility in Kourou (pre-launch
testing). Some of my early graduate school years were also spent
writing an object-oriented interactive data analysis and display
package for space physics data sets. While it was never widely used,
it was the seed that inspired the now widely used PAPCO package. My
PhD dissertation was in part based on data from the Polar spacecraft,
and presented some unique, new measurements of Energetic Neutral Atoms
(ENAs), which have since been confirmed and developed further using
data from the IMAGE satellite.
In 1998 I received my PhD and began a postdoc at Los Alamos National
Laboratory in New Mexico. I initially worked on attempting to
understand the data from a prototype ENA detector, named LENA-p,
launched on a military satellite in a high eccentricity orbit. The
data from LENA-p appeared corrupted, and I moved on to other tasks. I
did additional work on the Polar ENA data, worked on data assimilation
and data fusion, including a method for measuring magnetospheric
electric and magnetic fields from time-series correlation of drifting
energetic particle populations. In the final year of my 3-year postdoc
I began supporting LANL's role in the Sloan Digital Sky Survey (SDSS)
project. The SDSS was a ambitious project astronomical project to
digitally map a large fraction of the night sky for primarily
cosmological studies. My work there consisted of observing support at
Apache Point Observatory in southern New Mexico, calibration work, and
control system work.
Toward the end of my postdoc I also spent time building a new program
at LANL to study autonomous sensor networks. Sensor networks is a term
now used for large wireless networks of simple nodes with sensing,
computing, and two-way communication to nearby neighbors. Sensor
networks are characterized by low power consumption, robustness,
stealth, and autonomy. It therefore has many uses from espionage to
scientific data collection. I worked on sensor networks from 2000
until 2003, and authored several successful proposals.
In late 2000 I became involved with the Magdalena Ridge Observatory
(MRO) Consortium, a group of universities gathered to build a
long-baseline optical interferometer for astronomy in central New
Mexico. The interferometer is currently under construction. My work
with MRO has consisted primarily of contributing to the overall
design, and working on the design of the control system. However,
since 2006 I am working on simulating the central phase tracking loop
of the interferometer. In 2004 I initiated a program to study the
ground layer atmospheric turbulence at the MRO site. I designed and
built a battery operated instrument with wireless data acquisition
capable of operating for many months without maintenance.
Through my work with MRO I became acquainted with the optical
interferometry group at the U.S. Naval Research Laboratory. I have
been collaborating with that group since 2001 on work related to the
Navy Prototype Optical Interferometer (NPOI), in Flagstaff, AZ. My
work with the NPOI has consisted primarily of developing new methods
for performing long coherent integration by post-processing the short
exposures recorded by the instruments. In 2004 we published a paper
showing the first optical visibility phase measured with the NPOI, and
numerous other papers have followed since. In optical interferometry
atmospheric turbulence limits exposures to a few milliseconds. However,
integrations of many seconds or minutes are often needed in order to
obtain sufficient signal to noise ratio (SNR) to make the measurement
useful. Unfortunately the noise characteristics of the short exposures
is such that SNR builds only slow as the integration time is
increased. The coherent integration techniques I have developed
overcome this problem, allowing much higher SNR measurements to be
performed in a short amount of time.
In 2003 I developed an interest in space elevators, prompted by
colleagues inside and outside of LANL. A space elevator is a cable
reaching from a point near the Earth's equator through geostationary
orbit and approximately 100,000 km into space. At the moment, carbon
nanotubes (CNTs) is the only material which is strong enough to be
used as a building material for a space elevator - at least in theory;
A macroscopic material that approaches even a fraction of the measured
strength of individual CNTs has yet to be demonstrated. A space
elevator could potentially replace some rocket launches and reduce the
cost of space access. My primary interests are the study of the
magnetospheric environment in the vicinity of the space elevator
cable, and how it interacts with the cable, the cargo, and
passengers. I have demonstrated that both the radiation environment
and the electromagnetic interactions between the space elevator cable
and the time-varying magnetospheric magnetic field are serious
concerns that need further study.
In 2005 I received funding to develop methods for applying genetic
programming to time-series data analysis problems. The typical problem
is one in which we seek a non-linear relationship between a set of
"input" time series and an "output" time series. The genetic algorithm
searches a space of algorithms or function trees which can represent
possible solutions to this problem. I am using this approach not
simply to find empirical relationships (other methods, such as neural
nets, can do that), but to use the genetic algorithm to develop
human-readable functional relationship which may lend themselves to be
analyzed for physical understanding. The method is easily combined
with physical intuition and can be constrained to search for
particular classes of solutions (for example 1st order differential
equations). I have developed a software tools and applied them to
prediction problems in space physics.
During the 2006-2007 academic year I was a visiting assistant
professor at New Mexico Tech in New Mexico. In the fall 2006 semester
I taught EE 521 Instrumentation and Measurements, EE 231L Digital
Electronics Laboratory. In the spring 2007 semester I taught OPT 300
Introduction to Optics, EE 212L Signals and Systems Laboratory, EE
308L Microcontrollers Laboratory, and advised a group of 4th year
undergraduate students on a design project. I spent the summer 2007
working at Los Alamos National Laboratory. In the fall 2007 I returned
to New Mexico Tech in a tenure track assistant professor
position. During the fall 2007 semester I taught EE 521
Instrumentation and Measurements, and EE 321L Analog Electronics
Laboratory. I also sponsored a 4th year design team to build a balloon
experiment for measuring atmospheric turbulence up to an altitude of
30 km, as well as advised another team building a high-speed sampling
system for Doppler measurements of explosion fragments. In the spring
2008 semester I am teaching EE 322 Advanced Analog Electronics, and EE
322L the associated laboratory class, and will continue advising the
4th year design teams. My current research focus is on optical
interferometry with the NPOI, machine learning for data analysis, and
most recently Kalman filtering for modeling of the Earth's
plasmasphere.
