00:00:29
Hello, welcome to this Group Discussion on
Research.
00:00:33
This is the first class, an introductory class
on this course which we have on Introduction
00:00:38
to Research.
00:00:39
I am Prathap, I am a professor in the Department
of Metallurgical and Materials Engineering
00:00:42
at IIT Madras, and these are our panelist.
00:00:46
Hi, I am Arun Tangirala, I am a professor
in the Department of Chemical Engineering
00:00:50
at IIT Madras.
00:00:51
Hi, I am Phanikumar Gandham; professor in
Department of Metallurgical and Materials
00:00:56
engineering.
00:00:57
Hi, I am Abhijit Deshpande, I am a faculty
member in Department of Chemical Engineering.
00:01:02
Hello, I am Andrew Thangaraj, I am a faculty
in the Electrical Engineering Department,
00:01:07
IIT Madras.
00:01:08
Right.
00:01:09
So, when we discuss about Research I think
the aspects that we need to look at are that
00:01:15
many students aspire to get degrees in which
are basically research based degrees.
00:01:23
And often based on our background a particular
person may not be completely aware of what
00:01:29
is involved in getting such a degree and how
is it perhaps different from other degrees.
00:01:34
So the first thing, first topic that we will
discuss today is, what does a research degree
00:01:40
such as MPhil, MS or PhD imply or represent.
00:01:46
I think what I would say is that it is really
different from the under graduate degree that
00:01:52
normally one pursue you say B.Tech or a B.Sc
and so on.
00:01:56
Because, normally in such under graduate degrees
you do a lot of courses, whereas in research
00:02:02
degrees what we normally think of is doing
something new, contributing, first of all
00:02:10
knowing what is there out in that area, picking
out favorite area and most importantly contributing
00:02:18
something.
00:02:19
It may be a small contribution but drops make
an ocean.
00:02:22
So, that really involves a lot of effort from
our side; whereas in a course based program
00:02:30
like B.Tech and so on we take courses we learn.
00:02:34
There is only a small part of discovering
something; it is more of learning.
00:02:40
Whereas, in research based degrees you are
trying to really discover something, think
00:02:48
and then postulate, validate, perform certain
experiments and so.
00:02:52
So, there is lot of self-contribution in this
research based degrees.
00:02:58
Yeah adding on to that, so that is the difference
as Arun pointed out that there are various
00:03:04
things which depend on oneself during a research
degree.
00:03:07
So, a course based degrees is where you know
the exams, the assignments everything is sort
00:03:13
of catered and everything is well designed.
00:03:15
But when a research degree lot of it depends
on the researcher himself or herself.
00:03:21
And those are the aspects we will be discussing
further on as to how what is meant by these
00:03:25
aspects of research.
00:03:27
So, one crude way of comparing these two things
is, if you conduct a final exam for a course
00:03:34
at the end of a subject of a class you write
a final exam, everybody is supposed to turn
00:03:40
in a very similar kind of answer script right.
00:03:42
So that is the key and you write similar answers
and you all get good marks.
00:03:46
In fact, at the end of MS or PhD, you cannot
submit a thesis which is similar to anybody
00:03:51
elseâs thesis.
00:03:52
Suppose to produce something which is unique
and different and only you have done the work.
00:03:57
So, that kind of represents the big shift
between a normal degree course and PhD.
00:04:03
Yes.
00:04:04
So, have that and mind, it is not just one
more degree after your MPhil, but or after
00:04:08
your Masters it is a really a different sort
of a degree when you pursue a PhD.
00:04:12
Yes, so that brings to the point about the
qualitative difference in PhD with other degrees.
00:04:19
One may have a misconception that the amount
of work, the quantitative work at a bachelorâs
00:04:24
degree, you do little bit more may be then
you can get a Masterâs degree.
00:04:28
But then you do twice of that, that does not
mean that you can get a PhD degree.
00:04:32
PhD is a qualitatively a very different degree
where you are training yourselves to become
00:04:37
a researcher and it is one different in also
a sense of the ability of a PhD.
00:04:44
Once you have finished the degree you are
also expected to be at a level that you could
00:04:49
guide another person to do a PhD, it is very
different that from other disciplines.
00:04:54
So, qualitatively there is a big difference.
00:04:57
Yeah and so, I would also like to add that
you know when you do an undergraduate degree
00:05:00
the boundaries are well defined.
00:05:02
There is a start point and you can tell exactly
when you are half way through the degree and
00:05:07
when you have completed the degree.
00:05:09
You can tell on the day you joined which is
your graduation day, which is the day you
00:05:13
pick up your degree all those things are well
defined.
00:05:15
In a research based degree, it is open ended.
00:05:18
So, there is a lot of discovery in the process;
you have to figure out when you have a learnt
00:05:23
enough and you are able to contribute enough
and you have become a master or somebody who
00:05:28
is well known in that field who has contributed
a lot in to that field, and therefore you
00:05:33
are in a position to pick up a PhD degree.
00:05:35
So, thatâs very different from typical undergraduate
degree.
00:05:37
So, we will now look at this question; What
is research?
00:05:41
So, I will may be start with Andrew and he
can tell you something.
00:05:48
Ok.
00:05:49
So, I keep coming back to this contrast between
a course and research.
00:05:54
So, let us take again very concrete differences.
00:05:59
You have a text book and a research paper,
I think these are the two things you can compare.
00:06:05
Text book is accumulated knowledge over several
years.
00:06:08
Somebody has understood and formalized that
knowledge in his head and he is putting it
00:06:12
out in a sequence of subject so that somebody
else can learn, that is a text book and that
00:06:16
is why you learn and that is what you to do.
00:06:18
When you do research, it is completely unclear
what will happen to that work after that.
00:06:23
You know you are going to the real cutting
edge of current day development round of the
00:06:28
subject and you trying to push the boundaries
in a direction in which nobody has thought
00:06:33
of before.
00:06:34
So, and nobody can be sure what will happen
to that work after that, maybe it is very
00:06:38
interesting, maybe it is not very exciting
later on, you cannot predict anything.
00:06:43
And when you do it will never be organized
in a very clean systematic way like a text
00:06:47
book is.
00:06:48
You will have to organize in your head and
take time over it.
00:06:51
So to me the text book versus research paper
difference of, may be a cutting as research
00:06:55
paper differences what comes to mind when
I answer the question what is research.
00:06:59
Yes, in often when students ask, is there
an any text book I can refer to so that I
00:07:05
could do my research.
00:07:06
May be if there were a text book them may
be it is too late to do research in that.
00:07:10
Yes, Exactly
I would also like to add that, in fact reiterate
00:07:16
what Andrew just said that the beginnings
of research are quite hazy.
00:07:20
In fact, it is so foggy and hazy that you
may think that is nothing or nothing is clear
00:07:26
to you in the beginning.
00:07:27
It is only the passion that drives you.
00:07:29
So, what is research?
00:07:30
Big integral part of research is learning;
that is a very important part in fact you
00:07:36
see the term search in research so you have
to search and discover.
00:07:40
So the searching is for both learning and
for discovering.
00:07:44
And that of course we will expand shortly
on that as to what you do to carry out this
00:07:49
searching part in research.
00:07:50
But I think the important part is the beginnings
are hazy, but there is a joy to the discovery;
00:07:58
provided you actually persistently pursue
what you want to really find out and so on.
00:08:04
In fact, it is like going into a city where
you do not know what the destination is, you
00:08:08
know that this city is good you heard, it
is your favorite city, it is like choosing
00:08:12
your favorite field of research but you do
not know which monument you want to visit
00:08:16
where you want to spend most of your time.
00:08:18
Yes.
00:08:19
And then in the beginning you take, that is
where you do a literature survey, find out
00:08:23
what are all interesting monuments or sightseeing
places in the city; and then you pick your
00:08:28
favorite monument and or your sightseeing
place and spend more time trying to know what
00:08:34
is there and may be contribute to that place
and so on.
00:08:39
It is, yeah, there is a lot of trial and error
in research and you have to be prepared for
00:08:43
it.
00:08:44
Yes, I think that is a very great analogy
that Arun just gave you and in fact we would
00:08:48
like to just share this quote from Albert
Einstein, which basically highlights this
00:08:53
fact that the research that we do involves
you know exploring unknown territory, so to
00:09:00
speak in, in a particular area.
00:09:01
He said, if we knew what we were doing, it
would not be called research, would it?
00:09:07
So, that pretty much highlights the point
that you know there something new, it is not
00:09:11
something that you can just go look up and
then say now I have done the research.
00:09:14
There is something new and you are going to
be the person who searches for this new stuff,
00:09:19
finds it and then shares it with all the people
around you.
00:09:23
Yes.
00:09:24
The other aspect of research even though we
are trying to give you in one hour some sort
00:09:29
of gist of what might be research is, from
so far discussion it is already clear that
00:09:35
it is very, very open ended.
00:09:37
Yes, in fact you need to research to find
out what is research also.
00:09:41
Your answer will be different from our answer.
00:09:43
There is another point about that there are
some prefixes used for research for example,
00:09:49
incremental research and path breaking research.
00:09:52
Generally, people donât start of saying
that I am going to now do path breaking research
00:09:55
that is not how we go about.
00:09:57
We do have a structured way of going about
performing our routine activities for research
00:10:03
and then we are trying to incrementally add
knowledge to what is already there and in
00:10:07
the process by serendipity or because our
mind is prepared, we are looking for clues
00:10:13
and then path breaking research happens.
00:10:16
It usually happens rather than you go out
starting to do that.
00:10:21
And I just want to add that, in research you
are the one who questions and you are also
00:10:25
the one who finds the answers.
00:10:26
Right.
00:10:27
When compared to text book thing where the
questions are then and you have to answer.
00:10:31
everyone knows the answer.
00:10:32
Right.
00:10:33
Just wants you to write it down.
00:10:34
But in research you ask questions and you
find answers.
00:10:37
The only thing that is important to keep in
mind is you ask relevant questions.
00:10:41
Yes.
00:10:42
Not absolute questions.
00:10:43
And you give answers that make a difference.
00:10:45
Yes this is true.
00:10:46
Through this discussion some of the points
that we are going to look at are you know
00:10:50
philosophical points like, what we have been
looking at discussing so far which are you
00:10:55
know the grand scheme of things within which
we you know do carry out a research or we
00:11:00
look at a research and so on.
00:11:02
There are also lot of mundane activities that
happen in that actually result in the process
00:11:08
through which we do a research in universities
and so on.
00:11:12
We will also touch up on those because those
are the day to day things that we get involved
00:11:15
in as we try to carry out a research.
00:11:18
So, one of those things is selection of a
research area and selection of your guide
00:11:24
or advisor.
00:11:25
So, these are the first things that you would
do when you try formally get into research.
00:11:29
Of course, you could do research on your own
as an independent person but most of us are
00:11:34
not doing that you know in our own lab hidden
away from everybody, we do it as a part of
00:11:41
a community, a scientific community which
you often you know is thriving in university
00:11:44
setting also in research labs and in industry,
R and D setting and so on.
00:11:48
So at least in the university setting, one
of the key things is you have to find the
00:11:51
area that you would like to work on and the
guide that you would like to work with.
00:11:56
And there is no, I mean like in many of these
things there is no single way in which you
00:12:02
do it, but the area you are interested in
is something that you have to understand on
00:12:07
your own.
00:12:08
I mean this could be due to a lot of general
reading you have done in over the years as
00:12:12
a student at various levels and you have found
some particular area that appeals to you,
00:12:17
that interests you in terms of kinds of details
that they are looking at, the manner in which
00:12:22
the area is being explored and so on.
00:12:24
And so, that is one way in which you can get
a sense of you know this is an area that you
00:12:29
would interested in.
00:12:30
You also have through your general reading
you will also have a sense of how much impact
00:12:35
that area has to the neighborhood you are
in or to the scientific community or the vault
00:12:41
over all.
00:12:42
So, that may also influence your interest
in a particular research area.
00:12:46
So, there is multiple factors that influence
what you may get interested in and you should
00:12:51
take all of those into account.
00:12:52
But it is I would say fundamentally it is
very important that you should be interested
00:12:56
in that area.
00:12:57
If you end up trying to do research, if you
just say that I want a degree and I want a
00:13:01
PhD degree and you just go join a university
and you just pick up whichever advisor is
00:13:05
willing to pick you up.
00:13:07
The biggest problem that will come is, the
day to day; you know the exploration that
00:13:12
you do which is part of your research will
not appeal to you.
00:13:15
And if it does not appeal to you it is difficult
for you to do good work in that area.
00:13:19
So, you have to look at it in the inverse
manner.
00:13:21
First of all, it should appeal to you; only
then you should be getting into it.
00:13:24
So, that is something that I wanted to share
with you.
00:13:27
One important aspect of this selection of
both research areas and guide and advisor,
00:13:32
is the central element in your thought should
not be worry.
00:13:37
In the sense, we always worry about you know;
Will I get a job afterwards?
00:13:41
Is this area really relevant?
00:13:43
So, there are lot of things associated with
worry.
00:13:46
Actually, one should look at it as a challenge.
00:13:49
And so, if you look at it from that point
of view because we emphasize enough that it
00:13:54
will be you who is the focus of this.
00:13:57
In general, one can say that in most research
areas and with many guides and advisor, if
00:14:02
you drive you will be able to actually make
a very good thesis and in the end actually
00:14:10
use that for to furthering your overall career
goals.
00:14:13
So, central element should not be worry but
central element should be challenge and interest.
00:14:18
And that is how you should try to make this
decision.
00:14:21
So maybe I should touch up on the more mundane
aspect of selecting area and advisor.
00:14:26
So typically, I mean this is what happened
to me I think for most people this is what
00:14:29
happened.
00:14:30
May be in your undergraduate or postgraduate
studies there was a course that you picked
00:14:33
up and there was something you did which really
appeal to you maybe it was thought to you
00:14:36
in a very well, very nice fashion and that
instructor also appeal to you.
00:14:41
So, this is typically how it happens.
00:14:44
So, it can even happen in the undergraduate
stage.
00:14:47
You do a substitute really like it, then may
be as a post graduate student entering university
00:14:51
you take a course with someone you really
like how the course went, how the person handled
00:14:55
the class, the subject matter and also how
they interacted with you.
00:14:59
So, all these things together can appeal to
you and then you might want to think, ok;
00:15:02
I can do a PhD in this area, I like this area
and do it.
00:15:05
This is the more mundane way in which it happens,
but I have seen many students do this.
00:15:10
I think this is something it shows that the
student is not very prepared I think.
00:15:14
They would take an undergraduate core area.
00:15:17
Like in Electrical engineering there is an
area called signals and systems they would
00:15:19
take that area and they will say I want to
do research in signals and systems.
00:15:23
It is fine, but except that you know all research
in Electrical engineering is in signals and
00:15:29
systems.
00:15:30
So that is the difficulty you know.
00:15:32
So, while you like a subject you should also
know that you know just because you learnt
00:15:37
it in undergraduate you cannot do research
directly in that area, it is very highly specialized
00:15:42
beyond that.
00:15:43
The area will get more and more and more specialized
as you go deeper and deeper into it and you
00:15:47
have to kind of anticipate that, but like
everybody said the guiding principles are
00:15:51
yes you should be interested in the area.
00:15:53
And also, say will be motivated by your advisor
both as a technically capable person and also
00:15:59
as a person.
00:16:00
All these things go into having a good fit
between you and your advisor.
00:16:05
So, I would like to add that among all the
degrees that student normally under goes,
00:16:11
PhD perhaps is the longest duration on a single
aspect with a single person.
00:16:15
With a single person.
00:16:16
It draws for about 4, 5 years, sometimes may
be even 6 or 7 in some sciences.
00:16:21
It is very important to pick the right advisor
who has both the energy to drive you to take
00:16:31
up the challenging aspects of the work and
also the experience to guide you when you
00:16:35
are into the difficulties coming over some
of these topics.
00:16:38
So, I think choosing an advisor is very important.
00:16:40
Yes, there is also a style of your own and
the advisorâs.
00:16:47
And I think there is good bit of thought that
you can give to that also.
00:16:51
Because sometimes those can also influence
because as we have said it is day to day interaction
00:16:55
over such a long period.
00:16:56
I think it is a very important point as you
must have probably now guessed, there is no
00:17:02
definitive formula that we can give to choose
an advisor or an area.
00:17:07
I think as for as choosing an advisor is concerned
as Abhijit just mentioned also mental compatibility.
00:17:13
I think the style of thinking whether it matches,
some students are really inclined towards
00:17:19
doing carrying out theoretical work.
00:17:21
While some students are made for experimental
work.
00:17:24
So, I think it goes back again to the same
point that we have mentioned earlier you need
00:17:29
to introspect a bit in and then figure out
what suits you, what you are interested in;
00:17:35
whether a theoretical work or an experimental
work or a mixed work and so on or you want
00:17:39
to do really the cutting-edge stuff and so
on.
00:17:41
So then of course, today there is no dearth
of information you can really go to website,
00:17:47
find out the profiles, check out the publication
record even probably read a couple of publications
00:17:53
and so on.
00:17:54
To figure out whether the work really excites
you, and remember in all of these there is
00:17:58
no correct answer.
00:17:59
There is always a discovery process, there
are cases in which students have switched
00:18:04
advisors, of course that is a very small proportion.
00:18:06
But even if that happens you should not be
really getting a depressed about that.
00:18:11
Ok.
00:18:12
So, what is important is upfront to be very
frank and honest with your advisor, express
00:18:18
what your interests are and also listen to
what your potential advisor has got to say,
00:18:23
and do your own little bit of research about
the advisor.
00:18:27
And the same goes with the area as well you
have to really introspect as Andrew said there
00:18:32
are subjects that interest you, but that is
just a beginning it is just giving you an
00:18:37
idea of what to get into and you have to really
probe a bit more into a broad field to figure
00:18:43
out where you are.
00:18:44
And I think the guide is a very appropriate
term going by the previous analogy we said;
00:18:48
research is about going into an unknown territory
or visiting an unknown city and you are visiting
00:18:53
monuments remember you have guides telling
you giving to the history about it.
00:18:56
So, here also the guides will tell you, when
you pick a certain area and when you are talking
00:19:01
to a potential advisor you can find out from
the potential advisor, whether it is worth
00:19:07
carrying out research?
00:19:08
How crowded this area is?
00:19:09
How crowded this bus that you are going to
get in to is?

It is also discovery process.
00:19:25
And I would like to stress also, perhaps per

00:19:51
So, that groundwork is very essential.
