Choonho JUNG, Ph.D. - 2006
Thesis: Selection of faceted bicrystalline silicon primary growth morphologies
in near-eutectic Al-Si alloys under low velocity directional growth conditions.
Choonho came to Iowa State from Pusan National
Universtiy in Korea, where he earned BS (1998) and MS (2000) degrees in Metallurgical Engineering. Choonho's work
involved experimental investgation of primary silicon growth morphologies in Al-Si alloys under directional
solidification conditions. In March of 2007, Dr. Jung took a position as a Postdoctoral Research Associate
at Rensselaer Polytechnic Institute.

Halim MECO, Ph.D. - 2004
Thesis: Morpholgical selection at extreme rates
Halim Meco came to Iowa State in Fall 2000 from Middle East Technical University (METU) in
Ankara, Turkey, where he received BS and MS degrees in Metallurgical and Materials Engineering. His
work included a theoretical and experimental analysis of melt-pool behavior during melt spinning, where
both upper and lower limits for melt-pool stbility were identified. Other work included investigating
the twin boundary core structure in primary silicon dendrities in Al-Si alloys, thermodynamic analysis
of the Fe-B system, and phase selection during melt spinning of Al-Sm and Ag-Sm alloys. Halim was awarded
the MSE Excellent in Research Award for his Ph.D. research. After graduation, he accepted a post-doc position
with Prof. Krishna Rajan in the MSE Department at Iowa State.

Bryce RUSTWICK, MS - 2005
Bryce entered the graduate program in Materials Science and Engineering after completeing a BS in Engineering Science at Iowa State University. He studied crystal-melt interface energy anisotropy and performed grain boundary groove measurements in succinonitrile and pivalic acid, two transparent metal analog materials. After completing his MS degree in 2005, Bryce accepted a position with Boston Scientific. |

Luke ENGLAND, MS - 2004
Thesis: High-rate growth mode transitions in aluminum-silicon eutectics
Luke began his graduate work in Fall
2002, after receiveing a BS degree in Materials Engineering from Iowa State University.
His research was primarily focused on understanding the flake to fiber (i.e. quench modification)
transition in Al-Si alloys. Specifically, he used phase fraction and aspect ratio measurements to identify a
critical dimension defining the phase spacing in the irregular eutectic structure. After receiving his MS degree
in 2004, Luke took an engineering position at Micron Inc. in Boise, Idaho.

Melissa VER MEER, MS - 2002
Thesis: Morphological Selection During Alloy Solidification
Melissa came to Iowa State after earning a BS in Chemical Engineering from
the University of Nebraska. Supported by a NASA Research Fellowship, she
investigated initial transient effects on morphological instability and
selection under directional solidification conditions. Since January 2003,
Melissa has been working at Schlumberger in Lawrence, Kansas, where she is
the Polymer Laboratory Manager.
