As a scientist, he should make science and worry about his specialty and its progress; this usually means making basic science. He should also give support to public and private entities which develop their activity in sectors of his competency: hospitals, industries, laboratories, etc. He should work in a team, which implies an important effort in formation and qualification of technicians and graduates, who will finally enter in sectors where research is an important aspect. Scientific research today doesn’t have any sense if not performed in a global ambiance, and this also leads to establish and keep contacts around the world. A researcher should participate and give his opinion about the management of science, because he’s a main actor. Finally, society demands information about the scientific advancement, thus also supposes a divulgation task. In my scientific career I have tried to follow all the referred objectives that society demands to scientific researchers and, even if little is done about each one, finally represents a strong dedication.
