The strong support of Georgia Tech administration, in particular Professor Michael Thomas, Dean Gary Schuster, and Professor Laren Tolbert, was essential in putting the laboratories together. The hard work of Dr. Li Song, the first assistant director of LDL, was instrumental in putting LDL together. We also wish to thank NSF for a cost sharing instrumentation grant. The hard work of the postdoctoral fellows, graduate students, and the secretarial staff enables us to run this laboratory as successful as it is. With thanks to all!
