I am a physicist with a wide range of interests.
My original training was in theoretical particle physics, but some of
my research has overlapped with cosmology, solid state physics
(mainly superconductivity) and even the behavior of DNA molecules.
Although I started out as a theorist, I believe strongly in the
primacy of experiment over theory.
I have been fortunate enough to have worked on
several major physics experiments, including
the DØ experiment at
the ATLAS experiment at CERN,
and most recently, LIGO, the
Laser Interferometer Gravitational-wave Observatory.
I have taught physics, mathematics, and computer programming at
the undergraduate level and also occasionally taught or tutored these
subjects to younger students.
SUNY New Paltz
I'm currently the "lab guy" for the Department of Physics and
Astronomy at the State University of New York at New Paltz.
I also teach one section of the introductory mechanics lab (PHY211)
on Monday evenings.
I previously was a
Visiting Assistant Professor (2012-13) and Lecturer (2013-14)
in the same department.
In addition to teaching introductory calculus-based physics and
physics labs I developed a new course on the Physics of Sound and
Music, and I taught advanced courses in particle physics and optics.
I also taught introductory physics labs at New Paltz in 2005-2006.
I taught physics at the United States Military Academy at West
Point for two years (2015-17), as an
Assistant Professor in the Department of Physics and
In my first year I taught four sections (including labs) of Physics
201/202 in the Core Physics Program.
I was trained and used the Academy's traditional Thayer Method of
instruction (somewhat like a "flipped" classroom), which emphasizes
self-study and personal responsibility for learning, along with small
class sizes, in-class practice, and personal interaction with
The following year I taught mechanics to physics majors in the
Advanced Physics program.
Specifically, PH381, Intermediate Classical Mechanics, and PH482,
Advanced Classical Mechanics.
I also served as a faculty advisor to the Astronomy Club.
From 2005 to 2009 I worked on a science education project called
Interactions in Understanding the Universe,
which lets high school teachers and their students
access LIGO environmental data (from
seismometers, magnetometers and weather stations)
data for inquiry-based investigations called "e-Labs".
This is part of a larger collaboration between physics labs and
experimental collbarorations which use Grid computing, with the
overall goal of making Grid tools and resources available for
education and outreach, in addition to their use for research.
I worked at Vassar College twice,
first as a Visiting Assistant Professor (1993-95)
and then later as an Assistant Professor of Physics (2002-2005).
While at Vassar
I created an accessible course in General Relativity for
undergraduates, revamped the Modern Physics Laboratory,
and started the Vassar Journal of Modern Physics.
My research efforts were focused on LIGO and developing
the Einstein@Home project.
University of Michigan
As a research physicist at the University of
Michigan (2000-2002) I worked on several projects.
I helped test the use of "QoS" packet prioritization
for the transfer of data from the ATLAS experiment at CERN,
and I worked on the Web Lecture Archive Project, which recorded
physics lectures and technical training courses for distribution via
From 1995 to 2000 I was a Lecturer and later a Visiting Assistant
Professor (same job, different title) in the UM Physics department,
where I was a full-time instructor for introductory physics classes,
and in some case I was the Lecturer for introductory classes of 400 to
Model Solar System
While teaching an astronomy class at Marist College,
I learned about the
100 yard model of the solar system.
This is a scale model of the solar system which shows, at the same
time and on a linear scale, both the sizes of the planets and the distances
At this scale the Sun is about the size of a soccer
ball, the Earth is about the size of a peppercorn, and Pluto is a
grain of salt a little over 1000 yards from the Sun.
I've taken to calling it the "Peppercorn Model"
and I've constructed portable stations (with solar lights)
which can be put out at the appropriate distances.
One of the best places to experience this model
is on the
Walkway Over the Hudson.

From August 2009 until the spring of 2012 I was a stay-at-home
dad, taking care of our daughter Amanda, who was born 14 weeks
In addition to regular baby things, we had lots of doctor appointments
and therapy sessions through the Early Intervention program.
The good news is that everything is fine and she's now just a regular
nine year old who has a Deputy Black Belt in Tang Soo Do karate.
She says that when she grows up she wants to be a police officer.
And she loves sharks.
Halloween 2015, with my daughter.
I would go nuts staying at home without some kind of technical project
to keep me busy, even if I can only work on it during nap time.
So I taught myself how to create Apps for my iPhone and my wife's
My first app, called
is a simple fingerpainting app I made for my daughter, with a twist --
by connecting the iPad to a TV with a cable she can draw on the TV.
That was followed by
Please Take My Picture,
which help you ask someone to take your picture in any of more than 15
I have several more apps in preparation, and ideas for more to follow.
I do not have a blog, but sometimes I post notes for my friends to
Facebook, and these are generally readable by anybody (who has a
Facebook account, not just my "friends").
Here are a few that might be interesting:
is free planetarium software for your computer (Windows,
Mac, and Linux),
which can show you a realistic sky in
3D, just like what you see with the naked eye, binoculars or a
It is also used in real planetariums (including the
one at SUNY New Paltz).
I have created several
custom landscapes for Stellarium, which include the Walkway Over
The Hudson in Poughkeepsie (shown below),
and the beach in Ocean City, Maryland.
In 2004-2005, as a member of the LIGO Scientific Collaboration,
I was part of the team which set up a distributed
computing system called
which uses spare computing cycles on your home or office computer
to search through LIGO data for evidence of gravitational waves
from periodic sources, all while displaying a nifty screensaver.
I hope you will install the BOINC software that makes this
possible and contribute your own spare computer time to the project.
It's very easy, and worthwhile.
While LIGO recently detected gravitational waves, these were from
colliding black holes, not from continuous wave (CW) sources.
Einstein@Home has not yet made a detection of gravitational waves,
but they have also been searching through radio data from the Arecibo
which has resulted in the "re-discovery " of over 100 known radio
the discovery of over 50 new radio pulsars never before detected.
I was not involved with this part of the project, but I'm proud of the
progress it's made since I helped get the whole thing started.
As a part of my work on creating Einstein@Home I set up a test project
using the same BOINC software, called
After serving admirably as a test platform, the project was shut down
at the end of June 2005.
It was later brought back when it was deemed
useful for further testing and software development for I2U2.
Right now the project is running silent again, but I'm hoping to put
it to good use for a new mission in the near future.
I have taught physics -- and sometimes math and computing -- at the US
Military Academy at West Point, Yale, Vassar College, the University
of Michigan, the State University of New York at New Paltz,
St. Louis University, and Marist College.
Some of the teaching materials I've prepared over the years which
others might find useful include:
about waves on an Oregon beach.
