<br />Personal Statement<br />When I was middle and high school student, I spend much time with computer. At that time, I was lost in computer languages such as C and C++. The more I learn the computer language, the more I have interest in this field. Thus, I always tell other people to be a computer engineer and I decided to go on to university by majoring in computer engineering. In the university, I was studied in earnest on engineering from the beginning. When I was junior in university, I had a chance to study in university of Hawaii as training program. In university of Hawaii, I learned a professional English and computer engineering and this experience makes me to decide to go on to graduate school. However, I was in trouble because I have no idea that what kind of filed is necessary for engineering background. Accidentally, supervisor of my bachelor&rsquo;s degree thesis said that &ldquo;biomedical engineering is emerging field and your engineering skills are quite suitable for research of human body signal&rdquo;. Likewise, I think that applying my engineering techniques to the human brain is a very fascinating, absorbing and rewarding endeavour with many potential benefits for health care.<br />From master&rsquo;s student to until now, I have worked on biomedical engineering which utilizes the human body signal as well as I have studied on neuroscience. One of the research topics is brain-computer interface (BCI) which is the most fascinating field for patient or healthy subject to improve the quality of life. My work was helping to healthy people who use the BCI systems more easily and reliable. To do this, I made a sensory stimulator to stimulate on fingers and found this stimulation can help to imagined hand-movement easily by using machine learning and advanced signal processing techniques. The reason why I have focused on imagined hand-movement is the key feature of patients having a serious disability. Thus, neurorehabilitation is the candidate solution for these kinds of patients I think this is the purpose of making the BCI system. I hope my biomedical backgrounds and skills will be helpful to rehabilitate for patients as well as healthy people. I would like to attempt it to rehabilitate motor function in people with traumatic brain injuries as a postdoctoral scholar.<br />I am extremely interested in obtaining a postdoctoral position at your laboratory where I can contribute to its focus on neurorehabilitation for patients with brain injury. Because I have studied on biomedical engineering so far, my machine learning and signal processing skills can establish a successful neurorehabilitation system with BCI technology. Furthermore, I have a strong knowledge about hardware such as system design, development and maintenance. Understanding both hardware and software is my strong strength and this makes me can easily to design an entire system by myself.<br />Thank you for taking the time to consider this application and feel free to ask if you have questions.<br />Sincerely,<br />Sangtae Ahn.
