I for those environments. Data from the software

I would like to pursue a Ph.D. program in Electrical Engineering (EE) at Yale University,
because I am passionate about learning more concepts in EE as well as working on a research
project. As describe below, my positive research and academic experiences at Lafayette College
sparked my desire for graduate study.
I worked with Professor Jon Wallace at Lafayette College on indoor MIMO (multiple-input
multiple-output) channel characterization at 2.55GHz and 24GHz during the summer of my
sophomore year. The project aimed to test the capability of near mm-wave bands to be used for
wireless communications in the indoor scenario. My responsibility in this project was to perform
detailed ray-tracing simulations of the same environments where actual propagation
measurements were taken.
I began my research by learning to use several state-of-the-art ray-tracing tools to understand
their capabilities and limitations. After focusing on the most appropriate tool for our studies, I
captured several hallway and room environments into the tool and executed ray-tracing
simulations for those environments. Data from the software needed to be processed in MATLAB
to analyze channel characteristics such as path loss, fading, and MIMO channel capacity. One
difficulty we found was that in obstructed non-line-of-sight (NLOS) environments, the fit of
measured and simulated results was not acceptable at near mm-wave frequencies. I experimented
with changing the parameters of the simulation tool (such as number of paths simulated) and
modifying the properties of the simulated building materials (such as increasing loss). My results
led to the conclusion that ray-tracing can be used for near mm-wave, but new studies are needed
to carefully measure material properties in near mm-wave bands.
The entire summer was challenging and exciting to me. I learned several important aspects of
research during this experience, such as searching the literature and reading articles to explore a
new research area, formulating and trying different approaches to overcome setbacks, and
collaborating with other students and research groups on a project. My results were included in
an article in IEEE Transactions on Antennas and Propagation as well as a conference paper at the
2017 IEEE Antennas and Propagation Symposium. This provided me an opportunity to learn
how to integrate my research contribution into a larger project and present my results to others.
Not only was I proud of what I learned, but also I developed a strong interest in further study in
Electrical and Computer Engineering.
Besides the research on MIMO channel characterization, I had worked on several different
projects. Last summer, I worked with Professor John Nestor at Lafayette College on a
visualization of FPGA (A field-programmable gate array) PathFinder routing algorithm.
PathFinder is a router to solve circuit routing problem on FPGA. My responsibilities were to
study the algorithm and to implement a Java applet. The applet is for people to visualize cost
change of resource nodes when routing a simplified FPGA architecture with the algorithm. The
research provided me a great opportunity to combine my programming skills together with study
on routing efficiency in hardware. Currently, I am working on a thesis project to implement and  compare performance of floating point arithmetic on FPGA as well as a design project of a
simple wireless network on FPGA. They both provide me valuable practice on digital system
design and deepen my knowledge in specific topics.
As an Electrical and Computer Engineering (ECE) student, I have taken ECE courses in diverse
areas, including solid state circuits, embedded systems, and communications systems, each of
which has a significant laboratory component. I am also looking forward to taking a course in
digital signal processing offered in the Spring to prepare for graduate study. In addition to my
ECE degree, I am working on a computer science minor, providing a more in-depth treatment
and new applications on the software and algorithmic side of computing. Not only have these
undergraduate experiences encouraged me to extend my knowledge continuously, they have also
inspired me to solve problems from various perspectives.
My undergraduate experiences in ECE have guided me to my long-term career plan of working
in a research laboratory. The world of electrical engineering still holds innumerable secrets, and I
am excited at the prospect of devoting five years or more to learn advanced concepts and
exploring those unknown possibilities. Continuing EE study in the graduate school is a great
preparation to achieve my goals.
Although I have a wide range of interests in ECE, I have developed an interest in studying
wireless communications and networks after my research in mm-wave communication in my
sophomore year. I am fortunate to live in an era of wireless communication, and I want to
involve in future development of it. Besides that, my interest also lies in information theory and
its applications. Therefore, I would like to learn more concepts of communications and
networking in graduate school, and to have research experience in the area.
The reason I strongly desire to study Electrical Engineering at Yale University is not only the
high reputation of the Electrical Engineering department, but also the excellent facilities and
labs. EE department at Yale University provides outstanding graduate courses and research
opportunities in the area of Systems, which would be a good fit to my study interest. I wish that I
could have the chance to work in Professor Wenjun Hu’s group for research in networked
systems. Moreover, as an international student and a women engineer, I am attracted by the
diverse learning community and powerful networking at Yale University.
From my own perspective, the Ph.D. program in Electrical Engineering at Yale University would
provide me a best opportunity to accomplish my study in EE and to achieve my own career
goals. I believe that my previous undergraduate experience coupled with my passion in exploring
future EE has prepared me to engage in graduate study and to solve challenging new problems. I
sincerely wish that I could have this opportunity to continue EE study and contribute to your
community.
