|Following her freshman year of high school in 1994, Holly attended our month-long, NSF-funded "Young Scholars" program here in the Department of Physics & Astronomy at LSU. She helped me develop a simple, but meaningful, mechanical model to illustrate how protostellar disks might fragment to form a binary star system. Holly currently is in her senior year at St. Joseph's Academy, Baton Rouge.|
In the summer of 1992, following her junior year of high school at
Archbishop Blenk High School in Gretna, LA, Mandy attended our
month-long, NSF-funded "Young Scholars in Astronomy and Space Sciences"
program here at LSU. During that time, she constructed a simple,
but meaningful computer model of warped galaxy disks, comparing the
velocity maps of the modeled galaxies to published velocity maps of
real galaxies. According to
her resume, in May, 1997, Mandy
graduated from Tulane University's School of Engineering
with a B.S. in Biomedical Engineering.
In the summer of 1993, James attended our month-long, NSF-funded
"Young Scholars" program here at LSU. Working with me during that time, he
located optical photographs of all the major spiral galaxies for
which good HI (radio frequency) velocity maps exist and carefully
measured quantitatively the structure (e.g., pitch-angle) of each
optically visible spiral arm in each galaxy. This data has since
been used to examine to what extent the twists in tilted-ring models
of warped spiral galaxy disks match the optically visible spiral structure.
In the fall of 1994, James enrolled in LSU's Honors College and immediately became involved in the research activities of the department's experimental gravity wave group. During his tenure at LSU he also worked with the low temperature, condensed matter group and participated in two NSF-sponsored summer research (REU) programs: one at Pennsylvania State University and another at UC, San Diego. In May, 1998, James expects to graduate with a 4.0 grade point average, having earned a dual degree: B.S. in Physics and a B.S. in Mathematics.
Through the NSF's Division of Graduate Education, James has been awarded an NSF Graduate Research Fellowship in physics (out of 35 such awards nationwide; see the complete list of 1998 awards) and, in the fall, 1998, plans to join the experimental condensed matter physics Ph.D. program at Pennsylvania State University.
During her freshman year of high school (1999-2000) at St. Joseph's
Academy in Baton Rouge, LA, Meagan asked whether I would help her choose
and then develop a science fair project on some astronomy topic.
She decided to write a computer program in Liberty Basic to show what
a Doppler (radial velocity) map of Saturn's rings will look like when
the Cassini spacecraft flys over the pole of Saturn in 2003. After coupling
the results of this program with a great deal of background reading, she
prepared a spectacular science fair presentation. Her presentation not only
won her assigned division, but at the regional competition she won best overall.
Here is an excerpt from the e-mail message that she sent to me on 3/1/00,
following this regional competition:
During her sophomore year at St. Joseph's Academy (2000-2001), Meagan worked on an observational astronomy project with Mark Slovak and, based on the results of this project, also competed very successfully in science fair competitions. On March 7, she placed 2nd in her division at the regional competition and, as a result, received an invitation once again to attend the year's International Science Fair. (Meagan's poster at this March 7 regional competition was featured on the cover page of the 16 March edition of LSU's weekly publication entitled "LSU Today.")
|Undergraduates at LSU|
|Jeffrey E. Anderson|
|During his tenure as an undergraduate student at LSU (1985-89), Jeff Anderson worked with me for over three years, contributing quite significantly to my group's ongoing research activities. As an integral part of our efforts to analyze the results that came from large-scale numerical simulations of evolving astrophysical systems, Jeff took complete control of the computer programs that we had developed to construct and display three-dimensional images of protostellar gas clouds. (Our computer-imaging programs at the time executed on a VAX/750 and were derived from programs that had originally been developed under the direction of Gabor T. Herman in the Department of Radiology at the University of Pennsylvania Hospital to image medical CT-scan data.) Jeff constructed, catalogued, and stored on videotape literally thousands of images, producing some of our earliest animated sequences of time-evolving astrophysical models. During his first few years at LSU, Jeff pursued a double major in physics (astronomy option) and history. Ultimately, he decided to focus his efforts on history. He received his B.S. in History from LSU in 1989, and was accepted into the graduate History program at the University of Michigan. His graduate research has involved extended periods of study at the University of Oxford, England.|
While pursuing his B.S. degree in physics at LSU, Donovan
worked with me and members of my research group for a couple of
years. He helped me think through the design of a 3D volume
rendering algorithm designed to execute on a massively parallel,
distributed memory computer architecture and helped investigate
possible connections between the twisted-disk structure of
extended neutral hydrogen disks and optical spiral arms in
spiral galaxies. Before leaving LSU, Donovan also generated some
simple holographic images from purely numerical data to demonstrate
how computer-generated holography might be useful in the analysis
of time-evolving, complex 3D data sets.
When he graduated from LSU, Donovan entered the Astronomy Ph.D. program within the Department of Physics & Astronomy at the University of Alabama. While there, he worked with Bill Keel and Gene Byrd, focusing on an infrared analysis of galaxies (see, for example, 2000, ApJ, 545, 171) and he attended the Les Houches 1998 Summer School on "Infrared Space Astronomy, Today and Tomorrow."
While pursuing his B.S. degree in kinesiology at LSU, Pete
worked with me extensively on the development of my online,
graduate-level textbook entitled, "The Structure, Stability, and
Dynamics of Self-Gravitating Systems." In particular, Pete helped
me design the entire layout of the book, and he was reponsible for
putting in, and keeping up-to-date, all the numerous hyperlinks
within the book. Pete's work on this Hyper_Textbook has been formally
acknowledged in the July/August issue of "Computers in Physics",
where the book was featured in the "Internet Goldmine" section of
Pete completed his B.S. degree in December, 1999, and was admitted into medical school at the LSU Health Science Center in New Orleans, LA.
Over the two-year period 1996-1998, Dave Sherfesee worked with me on a variety of
technical programming tasks associated with my development of a
graduate-level, on-line hypertext book entitled,
"The Structure, Stability, and
Dynamics of Self-Gravitating Systems." I am particularly grateful
for the versatile, yet user-friendly interface that he developed between
some of the book's hypertext pages and various Mathematica® tools.
Check out, for example, his Mathematica Applications that permit the user to
Laplacian of virtually any analytically expressible
functions in spherical coordinates.
In December, 1997, Dave received his B.S. in Physics from LSU, having
completed the degree in three and a half years with a 4.0 grade point average.
Through the NSF's Division of Graduate Education, Dave has been awarded an NSF Graduate Research Fellowship in astronomy (out of 13 such awards nationwide; see the complete list of 1998 awards) and, in the fall, 1998, plans to join the astronomy Ph.D. program at UC, Berkeley.
|Undergraduates at Other Universities|
|The summer between his freshman and sophomore years at Duke University, Jim attended an intensive 2-week, high-performance computing workshop at LSU that was organized by a handful of faculty associated with our Concurrent Computing Laboratory for Materials Simulation (CCLMS). In collaboration with another student (Gabe Rivera) attending the workshop, Jim designed from scratch an algorithm by which 3D data sets can be successfully imaged on a massively parallel, SIMD-architecture computer. Currently, Jim is pursuing his bachelor's degree in physics at Duke.|

|Papers coauthored with Tohline: [See references #61, C21, C23 ]|
In 2001, Patrick received his Ph.D. in Physics from LSU, having completed
his dissertation entitled,
"Numerical Simulations of Dynamical Mass
Transfer in Binaries."
This research work was conducted under the guidance
of both Juhan Frank and me.
In addition to the contribution to astrophysics that he has made
through the completion of his dissertation research, Patrick has made two
very significant contributions to our program here at LSU.
First, he was extremely instrumental in helping us build and bring to
full functionality the computer-controlled telescope that resides at
Highland Road Park Observatory,
which is jointly maintained and operated by LSU, the Park and Recreation
Commission of East Baton Rouge Parish (BREC), and the Baton Rouge Astronomical
Society (BRAS). Second, he completely rewrote my group's gravitational
CFD code in a form that includes explicit calls to mpi and therefore permits
it to be run efficiently on a variety of parallel computing platforms.
This code has been or is being used now to study a variety of interesting
astrophysical systems. Thanks, Patrick!!
Upon completing his dissertation research, Patrick moved to the University of Missouri, accepting a postdoctoral position to work with Jack Burns on some cosmological problems. He has since moved -- following Burns -- to CASA in Boulder, CO.
