Motivation for PhD
•
•
•
•
VTU requirement for promotion
Cultural capital (add the Dr prefix)
Masochistic mindset (long pain period)
Enjoy discovery / writing / talking

Slide 4
Work Ethic
•
•
•
•
•
INDEPENDENT research
It is YOUR thesis, not the Advisor’s!
The advisor is not a NANNY!
CANNOT do PhD as side business
Focus on ONE problem at a time
–
2 * 0.5 << 1 * 1
• WELCOME criticism of your work

VTU PhD Workshop
Slide 5
Survival Pre-requisites [1]
• Ability to look at life in a perverse (creative) way
– (Mark Twain) Age is an issue of mind over matter.
If you don't mind, it doesn't matter !
• Patience and mental strength to negotiate the
troughs (inevitable for every PhD)
• Trust your gut feelings in spite of negative results
– Luck favors the prepared mind (Pasteur/Hamming)
• Good sense of humour – you will definitely need it!
• Ability to smile (through gritted teeth) at advisor

Slide 6
Survival Pre-requisites [2]
• Industry experience – NO!
– "Real problems" only imply short-term
applicability
– May even be counter-productive since
immediate reaction is to start programming,
rather than conceptual thinking
• PhD registration X
 Research Scholar
• PhD is “training to do research” AND
“actually doing research”

Slide 7
VTU Faculty Specifics
• Difficult to devote time due to academic
and familial responsibilities
– Make sure to set aside a fixed daily time slot
for research and make this sacrosanct
• Course students can participate in the
research work under your direction and
thereby accelerate the progress

Slide 8
Good PhD Thesis
• Relevant to society – NO!
• Relevant to industry – NO!
• Right question: “Did I have fun thinking about
the problem and did I devise elegant solutions
that I am proud to show my mother (and she
didn't find any mistakes in the proofs)?”
• Doing a PhD is hard enough without the
burden of additional expectations ...
• All good dissertations find their way into the
real-world sooner or later

ENVIRONMENTAL
ASPECTS

VTU PhD Workshop
Slide 10
BAD ADVISOR CHOICE
• Knows less about the topic than you do
(even at the beginning)
• Not visible in the research community
• Says “Yes” to a student without assessment
• Popular with students due to low
expectations, not subject mastery
• Most notable achievement in last five years
has been getting his PF transferred

Slide 11
GOOD ADVISOR CHOICE [1]
• Junior Young Turk
– Great enthusiasm and involvement
– Current with research topics
– Remembers PhD tribulations
– Expects the world from you
– Micro-management of your work
June 2010
VTU PhD Workshop
Slide 12
GOOD ADVISOR CHOICE [2]
• Senior Big Shot
– Broad perspective of research area
– Can advertise your work well
– Provides academic freedom to explore
– Perenially rushed for time
– Will not write your thesis
June 2010
VTU PhD Workshop
Slide 13
BAD CHOICE of FRIENDS
• ondu idly-vada / by-two coffee dost
– Unless your thesis topic is “Topological
sorting arrangements of circles and donuts”
• Indian philosophy buff
– Indian philosophy is an intellectual mechanism
for providing extremely sophisticated reasons
as to why work cannot be done
• Lazy genius
– Will drag you into the mud with him
June 2010
VTU PhD Workshop
Slide 14
GOOD CHOICE of FRIENDS
• Technically competent and ambitious
– a healthy spirit of both cooperation and
competition
• Willing to call “a spade a spade” and criticize
you to your face
• Brings out the best research in you
June 2010
VTU PhD Workshop
Slide 15
RESEARCH COMMUNITY
• Take every opportunity to meet with the
“movers and shakers” in the field
– attend local international conferences such as
COMAD, HiPC, FSTTCS, IndoCrypt, …
– attend summer schools (Yahoo, Microsoft, …)
– apply for six-month internships in research labs
after you are about half-way through your thesis
– send technical reports for comments outside
– for funding, approach academies (INAE/IASc
/NASc /INSA) and DST/CSIR/KSCST/VTU
June 2010

Slide 16
REAL WORLD
• Family
– starts calling you a “visiting professor”
– question your sanity with cold-blooded regularity
• Well-wishers
– take great delight in asking you
“Is the thesis done yet?”
“Can we call you Doctor now?”
“Do all PhDs take this long?”

ASPECTS

WRITING and PRESENTATION
IMPERATIVES
• It is your duty as a scientist to share your
discoveries with others
• Your work is understood only from what you
present / publish
• You are evaluated only based on what you
write in your reports, etc.

Acquiring Writing Skills [1]
• http://dsl.serc.iisc.ernet.in/~haritsa/geninfo/techwrite.ppt
(by Vikram Pudi)
• Essential for both publications and thesis
• Spelling: Automated Spellcheckers
• Style: Elements of Style by Strunk & White
– Clarity, elegance and flow
– Technical precision is paramount
• e.g. rampant misuse of “optimal” and “ideal”
– Avoid ornate language – this is not a literary exercise
• e.g. The linked list appeared like a chain of jasmine flowers

Acquiring Writing Skills [2]
• Organization
– Modular (like programming)
– Linear narrative (no “item songs” )
– Minimize redundancy
• Choose good titles/acronyms (like variable names)
– Time Will Tell: Leveraging Temporal Expressions in IR
– Real-time commit protocol called PROMPT
(Permits Reading Of Modified Prepared-data for Timeliness)
• Read and revise word-by-word!
– 10 page paper usually takes a month to write satisfactorily
June 2010
VTU PhD Workshop
Slide ‹#›
Acquiring Presentation Skills
• Slides should be in large font / visible colors
• Ideas should be conveyed through
pictures / animation as far as possible
• Focus on conveying the main idea, and not
every single detail
• Rehearse the entire talk a few times
• Memorize the inter-slide transitions
• Carry out dry-runs with your peer group
June 2010
VTU PhD Workshop
Slide ‹#›
PUBLICATIONS
• ESSENTIAL to publish at least TWO papers
before submitting thesis
– Progress milestones  confidence buildup
– Honest feedback from anonymous experts
– Early warning of potential disaster situations
– Ideas for future work
– Thesis gets written/revised at a steady pace,
not delayed to the end, when it can prove to be
an overwhelming task
– Makes the resume speak for itself

PUBLICATION FORA
• Unique feature of CS: The top conferences
and journals are viewed as equivalent fora.
– Evaluating Computer Scientists and Engineers
for Promotion and Tenure
• David Patterson (Univ. of California, Berkeley)
• Lawrence Snyder (Univ. of Washington, Seattle)
• Jeffrey Ullman (Stanford University)
“In those dimensions that count most,
conferences are superior.”
“Conference publication is both rigorous
and prestigious.”

CS Conference/Journal Quality
• Most reliable, comprehensive and recent are
the rankings by Australasian CORE
• ~1500 conferences and ~2000 journals
• Ranks them into A+, A, B, C categories
• Website: http://www.core.edu.au/
• Goal should be to publish in A+ and A
categories
• ICDE database conference (A+): ~15% accepts
