My main focus is geotechnical engineering. Over the years, developed interests in structures, sustainability, leadership and numerical methods based on my work related experiences. As a researcher, I have pursued my desire to collaborate with others in areas beyond my own. My suggestion is to remain open to all of the possibilities and maintaining your curiosity!
It is mainly by the topic which is specific. This topic itself may be embedded in a broader category. The key words should cite some associated with the specific topic and some in the broader context so that the thesis would receive wider publicity. Subsequent research may cover newer areas and if these are also covered in the subject matter of the thesis then the thesis title should reflect that.
Though a scholar's higher certificate is often used in determining his/0her specialization, I think today it is wrong to do that today. A researcher's interest that drives his or her studies most times from his/her diverse background, largely evident in their publications mostly define his or her specialization.
through the topic of his/ her thesis or dissertation and from subsequent researches, As a first step, and then the experience gained in subsequent stages, Science advances and develops
In a formal way, a researcher's area of interest (specialization)should stem from the area from the topic/title his/her research thesis or dissertation. It shows the person wants to be relevant in that area of that course of study but may still do research in other areas and also collaborate with other researchers in other field (multidisciplinary research).
Researchers frequently belong to a general speech community of specialists with identical professional and normative standards. As you have rightly observed, a researcher's dissertation topic provides us with certain clues by which we can identify his/her general and even specific areas of specialty. However, as time goes on, researchers may become inclined to focus on technical tributaries and venues which are totally different from the main area of general specialty.
The doctoral work usually forms the basis of specialisation.
If you see that a particular author is repeatedly publishing on the same topic then it can be assumed that the author is specialised in that particular field.
It is necessary to evaluate the total scientific output of the researcher to determine his general and specific research area! Thesis and/or Dissertation chapters (subject, review of literature , materials and methods, results and references) and research activity after the recent scientific degree.
It can be from his proposed research topic if the topic is a new area of research and its a new ground to explore by his supervisor but sometimes its better to be given the research area by the supervisor since the supervisor has an area of interest at a given time that he is interested in exhausting before venturing into another area of interest.
In my opinion the researcher’s specialization determines highest degree acquired on which field and on the basis the number of publications or the citation index in reputed scientific journal. Other scientific activity techniques are used for measuring the collaboration activities of researchers and community collaboration activities (e.g. co-authorship, co-partners in projects, and co-cited publications). At a regional level, publication and citation data are also patterns of research collaboration: they identify sub-fields that reflect specializations,
In other words, if someone asks me to determine the precise specialization of a researcher, I will returne to what he did and study in his thesis or to his subsequent researches or both of them?
In fact , the specialization determines the highest and the grade acquired on which major and on the basis the number of citation in reputed located journal. Moreover the scientific techniques are used for culcolating the collaboration activities of the person.
I think in general the thesis relevant topics and then area of the research interest of the scientific scholar can give a clue into his or her area of specialisations
The terms of reference are determined according to the thesis presented, and the competence to determine the precise jurisdiction is often the authority of a discussion committee
Yes, young scholars get involved in every research related to their field but began to narrow down after sometime especially after M Sc and more focus and specific after Ph D.
I would say, if I may, a mixture of previous experience, research interest and personal knowledge. We cannot exclude years of work and practice simply because of thesis. Thesis or dissertation sometimes reflects the best interest of the supervisor. We cannot blame the PhD candidate for the preference of the supervisor. I would ask the candidate, which area of specialization do you belong? And there we will get some answers and discuss them.
It is actually a build up from the undergraduate level, the person's area of interest as it grows to higher level in attaining higher degrees like MSc and core specialization in chosen field when the PhD programme is competed.
You are meant to be rooted in a specific area of your field and with persistent, rigorous researches and collaborations, the person can become a voice to reckon with.
