Recommended for: First-year graduate student of G30 program who belongs to the Division of Biological Science, Graduate School of Science.

close Course Overview

Course Overview

Nowadays, many life science researches are conducted by using biochemical and biophysical methods, which has been developed and improved a lot in these days. In this course, first I will introduce basic ideas and principles of such methods, and then show examples how to apply these methods to solve important questions in modern life science.

Key Features

Since this course covers the students who have a broad range of different background, I take a lecture style with emphasis on communication between me and students. It means that I will not just give a lecture in the room, but I expect interactions between us. This course just started last year with quite number of students, I favor to stop may talk if students do not understand the contents, and ask questions to clarify what they feel difficult. So sometimes one topic takes long time to explain, even use all one session. I also give a quiz to help them understand the topic. At the latter half of the course, I show examples of how to apply the biochemical and biophysical methods to clarify the important life science questions. By using actual analysis published on the international journal, I hope students can get a hint to overcome their daily research problem, and apply these methods to their own projects.

Course Aims

Important subjects in current modern life science have been investigated by using the biochemical and biophysical methods. The aim of this course is to introduce fundamental principals of such methods, and insights into functions of gene products in vivo and in vitro, obtained by these analyses. Lecture will begin with explanation of principals, and will be followed by introducing actual analysis.
