I entered the MSU physics graduate program in the Fall of 2011 and
am pursuing a PhD with research in solar physics. I received my
B.S. in physics in 2003 from the University of Minnesota, Twin Cities
followed by seven years of software development work for the Compact
Muon Solenoid project at CERN. I left CERN in 2010 and worked briefly
at the Observatório Nacional in Rio de Janeiro before coming to
Montana to resume my studies.

At the time of this writing I have not selected a thesis topic or
begun any program of research, but here are some of the things that
interest me as possibilities at MSU and from previous experience.
Large-scale scientific computing. Every sub-field of
science is transitioning into a new era where increases in data volume
necessitate new approaches to data analysis, as well as opening up new
possibilities for discovery. At MSU, I am interested in finding ways
to use expansive datasets such as from the SDO mission to do
large-scale statistical studies that were not possible in previous
Acceleration of particles by the sun. The sun has the
largest and most active magnetic field in the solar system and is the
best place for us to study natural particle acceleration processes in
detail. The same events which are responsible for impressive solar
flares and coronal mass ejections are responsible for accelerating
particles anywhere from 1 MeV up to the GeV scale. These mechanisms
are likely analogous to those which accelerate ultra-high-energy
cosmic rays, where kinetic energies exceeding 10^20 eV have been
Coronal mass ejections, solar wind, and the space environment.
Coronal mass ejections are solar events whose effects may be felt here
on Earth. The acceleration of asteroid-sized amounts of material into
space and the subsequent impact with the Earth's magnetic field is
responsible for the auroras as well as for radio and satellite
disturbances which have an impact on our modern way of life.
Structure of the heliosphere. The interaction between the
heliosphere and the interstellar medium is only recently being made
available to direct observation. Measurements from the still-going
Voyager probes and energetic neutral particle measurements from the
IBIX spacecraft have brought forth new questions about the size, shape
and structure of the outer edge of our Sun's influence.
The solar cycle. The roughly 11-year solar cycle modulates
many solar phenomenon including the number of sunspots, the solar
irradiance, as well as the frequency of flares and CMEs. What is
responsible for this cycle, and for the subtle variations of it? What
has its impact been on the history of the Earth and the Solar System?
Exoplanet remote sensing. Kepler and other exoplanet
efforts are expanding the catalog of known worlds. Some planets with
wide orbits have already been imaged, and the atmospheres of eclipsing
planets can be investigated via spectral analysis of the host star.
We are just beginning to understand what variety of worlds are
possible in our galaxy.
When I'm not working on physics or writing some
computer program I like to...
Play guitar. I play mostly classical guitar, though I
dabble in blues, jazz, rock, folk and country as well as Brazilian
styles bossa nova and choro. I also like to experiment with a lot of
different sounds, and for this I have a Brian Moore MIDI guitar and
tons of software instruments like those from the Native Instruments
Komplete 8 package.
Go outside. Montana is great for this. I like biking,
hiking, and canoeing, though I suspect Minnesota was better for
Travel. I've lived in Switzerland and Brazil and seen a
lot of nice places along with my wonderful wife, Patricia. I suspect
we'll see a lot more interesting places as time goes on.
Take photos. When I'm outside or traveling I like to take
pictures. Sometimes I even take good ones. When I do, I put them on
my flickr photostream. A few random pictures are shown below.
