Message from foreign students in the lab

smileyTanzima Nuhat Sharna, PhD student from Bangladesh
University of Tsukuba, located in southern Ibaraki Prefecture, provides us the opportunity to explore Japanese culture, build our language skill, experience multidisciplinary research environment. Being a part of world-leading innovative university, the department of hematology promotes globalization of researchers by diversified intellectual members. During my work in this laboratory, I came to know about the impressive medical system in Japan. I have received incommensurable support from my supervisor and other lab members to pursue my research. They always encouraged me and motivated to build confidence. Furthermore, I got opportunity to gather high standard theoretical knowledge and practical experience of research in a well-equipped laboratory. We work here with numerous other international students. In addition, we can attend classes and discussions conducted in English which makes an international atmosphere. When I was preparing to apply in the Graduate school of comprehensive human science my supervisor guided me to prepare my applications. Besides, I attended an oral examination for screening process which was conducted in English over the internet. This procedure eliminates my fear of language barrier.  Research in Biomedical science is not very developed in Bangladesh. Therefore, when I shall go back to Bangladesh, I would like to introduce my knowledge from Japan for the betterment of my country.  

smileyCao Sy Luan, PhD student from Vietnam
I am an international student belong the Department of Hematology in University of Tsukuba. First, the reason why I chose this place for studying, because I want to learn about Japanese culture, one of the worthy cultures to learn, study and research about hematological field in professional and modern environment. After more than 3 years studying here, I have been learned a lot of thing, including good characteristics from Japanese, the way of scientific and logical thinking, how to manage experiments and scientific writing skills, the new knowledge not only in hematological but also in clinical, and biomedical filed, and so on. In the Department of Hematology, I have a chance to study and discuss with great and conscientious teachers as well as work together with friendly and kindly lab members. I also got opportunity to attend and represent my study in many conferences in Japan and other countries. I will try to apply as much as possible what I learned from here to contribute to develop my country when I go back. Finally, I greatly appreciate the teaching, helping and encouraging from professor Chiba and all members in the Department of Hematology.

smileyNguyen Thi Minh Yen, PhD student from Vietnam
I feel very proud to be a member of the lab. The friendly environment, the enthusiastic help and the devotion of the teachers made me more motivated to continue my research career. In hematology lab, I have learned a lot of new techniques, new knowledge in biomedical field, pathology, especially the way of thinking scientifically to solve research problems. Along with a great deal of hematological pathology, I believe this is a fascinating field to explore new biological mechanisms and, from that point of view, solves the problem of unique therapeutic drugs for treatment cancer diseases, particularly hematological neoplasm.
Actually, the number of hematologic cancer patients are rising in anxiety in our country. As a student from Vietnam, I think here is a worthy place to contribute and learn to hope that new opportunities for hematologic cancer patients will come true.

smileyRaksha Shrestha, PhD student from Nepal
Enrolling in the Doctoral program in Clinical Hematology at University of Tsukuba was one of the best decisions I have made in my life. Being one of the most highly research-intensive and respected universities in Japan, University of Tsukuba upholds its reputation for excellence with outstanding graduate programs like ours, in the department of hematology. Creative thinking, active discussions and strong mentor-student relationships are some among many positive attributes of the program. I have thoroughly enjoyed learning new techniques in the lab, reading broadly around my areas of interest and hearing about current research from local and visiting academics. A unique blend of interpersonal dynamics, strong work ethic and great camaraderie among the team creates a supportive and an amicable atmosphere in the lab. I believe that the knowledge and experience I acquire here will help me become an independent and competent clinician scientist in future. I feel immensely proud and equally grateful to be a part of this wonderful team at University of Tsukuba. Thank you for making it ‘my home away from home’.
