\noindent First of all, I would like to give my great admiration and thanks to my advisor Dr. Eldad Haber. It 
is my great honor to be his student. Dr. Haber introduced a fantasy world of scientific computation to me.
Particularly, it is under his direction that I had the opportunity to get so much valuable knowledge 
and research experience in this field. Without his instruction, I would not have had so much enthusiasm and progress 
in my graduate study and research. Dr. Haber is not only a prominent research advisor but a nice guide as 
well. His advice has brought me great benefit both in research and life.
	  
Also, I am so grateful to Dr. James Nagy and Dr. Michele Benzi. They gave me very valuable advice both in class and research. 
The advice from them is very precious to my future research life. In addition, 
the delightful atmosphere in their Computational Math group made my five-year graduate study quite pleasant.
	  
I would also like to thank Dr. Ajo-Franklin, who gave me much advice during my internship in the Berkeley National Lab, 
and Dr. Luis Tenorio, who gave me much help and instruction in writing the $A$-optimal design paper.
	  
Finally, I will give my great thanks and love for my family. My parents have given me support not only in finance 
but in spirit as well. My dear husband, Dr. Colton Magnant, has given me constant support not only in our home but also 
in research by collaborating with me on the $CO_{2}$ project.
