FINDING A GOOD RESEARCH IDEA

Prof. He's Recommended Reading

The foundational reference is Uri Alon's "How to Choose a Good Scientific Problem" (Cell, 2009):

• Navigate the space between easy/unimportant and hard/important problems
• Look for the "fertile middle ground"

Idea Evaluation Framework

Avoid:

• Overly trendy topics (too competitive, may be transient fads)
• Overly niche topics (unsustainable, limited community interest)

Seek:

• Balanced topics with longevity (will still be relevant in 3-5 years)
• Topics that align with your passions (you'll need to persevere through setbacks)
• Topics with practical applications (strengthen motivation sections of papers)
• Topics where you can make a unique contribution (your specific skills + the problem)

The Iteration Process

• Expect 10+ iterations to refine a research idea from initial concept to viable project
• This is normal, not a sign of failure
• Each iteration should sharpen: the problem definition, the proposed approach, and the evaluation plan

Research Roadmap Planning

Plan with concrete paper milestones:

• Paper 1: Foundational contribution (establish your approach)
• Paper 2: Extensions and deeper analysis (strengthen the foundation)
• Paper 3: Scalability, broader application, or system-level contribution

Develop your own visionary roadmap -- where is this line of work going in 5 years?

DECIDING WHETHER TO PURSUE A PhD (raintreebook Ch. 1.1)

Core Philosophy

"Research is less about chasing the 'optimal' strategy and more about avoiding the worst mistakes."

Common Misconceptions to Avoid

1. Doing a PhD because you cannot find a job (PhD requires inner drive, not desperation)
2. Pursuing a PhD because your family expects it (parents' expectations cannot sustain you through hardship)
3. Brilliant students choosing a PhD without clear purpose (try research first before committing)

Four Aspects of Mental Preparation

1. Clarify your dream -- Why do you specifically need a PhD for your goal?
2. Prepare for setbacks -- Can you accept 3-4 paper rejections and keep revising?
3. Embrace change -- Technologies, paradigms, and economic environments shift over 4-5 years
4. Dare to dream of excellence -- Promise yourself to contribute something meaningful

The "Don'ts" List for Undergraduates

1. Don't treat a PhD as an escape from unemployment
2. Don't rely on your parents' dreams instead of your own
3. Don't overload yourself with too many shallow projects (one deep project > ten shallow ones)
4. Don't underestimate foundations (algorithms, OS, databases, math, statistics last a career)
5. Don't chase low-quality publications to pad your CV
6. Don't neglect open-source or hands-on contributions
7. Don't ignore mentorship opportunities
8. Don't underestimate how competitive PhD admissions are
9. Don't expect quick results (one year minimum for meaningful undergrad research)
10. Don't forget to ask yourself the hard question: Why a PhD?

Four Highlights for Strong PhD Applications

1. Strong academic record -- ~4.5/5.0 GPA, strong in core courses
2. Research impact -- Quality publications at top-tier venues (CCF-A), not quantity
3. Open-source contributions -- A system with real users, GitHub stars, or top contributor status
4. Strong recommendation letters -- Detailed, from well-known independent scientists

Four-Year Undergraduate Study Plan

• Year 1: Explore, recap, reflect. Build foundations. Don't rush into the PhD decision.
• Year 2: Take core courses (algorithms, OS, databases, ML). Start projects and join a lab carefully.
• Year 3: Deepen and specialize. Commit to a lab. Start leading independent work. Critical summer for PhD application preparation.
• Year 4: Consolidate and apply. Finalize research record, prepare application materials. Limit applications to ~10 programs per letter writer.

PhD YEAR 1: THE 10 ESSENTIAL ACTIVITIES

Prof. He's structured first-year checklist for building good research habits:

1. Attend at Least 10 Seminars

• Priority: Invited seminars (potential faculty from top universities), visiting professor talks, faculty seminars
• Action: Ask at least 5 questions across the year
• Start small: Ask privately after the talk if you're shy, then build up to public questions
• Seminars teach you how experts think, present, and respond to questions
• KPI: Deliver 1 internal summary presentation synthesizing insights from all 10 talks

2. Read at Least 2 Top-Tier Papers Per Week

• Focus on leading conferences and journals in your field
• This builds both knowledge currency and analytical skills
• After reading, write a 3-sentence summary: (1) problem, (2) approach, (3) key result
• Track papers in a reading list (use GitHub or Notion)
• KPI: Write one 1-page mini-survey monthly summarizing best 8 papers with identified gaps

3. Find a Senior Lab Mate as Mentor

• Ideally someone 2-3 years ahead of you in their PhD
• Benefits: research idea guidance, navigating challenges, practical advice on tools and processes
• This supplements (does NOT replace) regular supervisor meetings
• Ask them about their mistakes -- learn from their experience
• KPI: Record 6+ mentor meetings per year with 3 concrete changes implemented

4. Read at Least 10 Papers from Your Own Group

• Start with recent papers from your lab
• Pay attention to the stage of the first author:
  • Year 2-3 students write more independently (less heavily edited by supervisor)
  • This helps you calibrate your own writing expectations
• Discuss these papers with peers and your advisor
• KPI: Present one internal slide deck connecting 3+ group papers to your research

5. Do a Side Project with a Senior Labmate

• Even if you have a primary research project
• Goal: hands-on experience in the FULL research cycle:
  • Idea generation
  • Experimental design
  • Algorithm development
  • Manuscript drafting
• This is about learning the process, not just co-authorship
• KPI: Produce one concrete outcome (GitHub repo, internal report, poster) within 8 weeks

6. Maintain a Reading List

• Use GitHub, Notion, or a shared platform
• Share with your supervisor so they can see your reading patterns
• Organize by topic, not just chronologically
• Include brief annotations (not just titles)
• KPI: 100+ papers tagged by topic and status by year-end

7. Keep Effective Collaboration (Be "Reliable")

The Chinese concept of "靠谱" (kào pǔ) -- being dependable:

• Always CC supervisor on external emails
• Inform collaborators 2 weeks before major deadlines
• Share final submissions with ALL co-authors
• Maintain records of contributions
• Ensure all co-authors declare correct COI
• KPI: Track achieved/missed deadlines, ensure 100% co-author acknowledgment

8. Utilize External PhD Survival Guides

Recommended reading:

• "How to Fail a PhD" by Matt Might (illustrated guide)
• Rob Hyndman's PhD failure guide
• "How to Build an Economic Model in Your Spare Time" (strongly recommended by Prof. He)
• KPI: Implement 3+ actionable practices in a personal "PhD playbook"

9. Sharpen System Development and Engineering Skills

• Learn profiling tools:
  • CPUs: VTune, Perf
  • GPUs: Nsight
• Study source code from related research papers
• Use GitHub as your "arsenal" of useful libraries
• Backup strategy: Maintain data/code/documents in at least 3 copies:
  1. Local disk
  2. Mobile/external disk
  3. Cloud storage (Google Drive, Dropbox, etc.)
• KPI: Contribute 1+ open-source system demonstrating profiling/optimization skills

10. Stay Updated with Latest Research

• Follow researchers on Google Scholar (enable email alerts)
• Subscribe to conference newsletters and proceedings
• Set up Google Alerts for your research keywords
• Join professional networks (Slack channels, Discord servers, mailing lists)
• Know conference deadlines: Put yearly recurring reminders on your calendar
• Track the submission cycle for your target venues
• KPI: Write a quarterly "state-of-the-field" memo (2 pages)

PAPER READING STRATEGIES

Deep Reading Method (for QE-level understanding)

For the ~50 papers you study deeply:

1. Before reading: Try to envision YOUR approach to the problem from just the title/abstract
2. During reading: Compare their approach to yours
3. After reading: Evaluate:
   • What was their unique contribution?
   • What are the limitations?
   • How could this be extended?
   • How does it connect to other papers you've read?

Trajectory Tracing

• Follow a single author's publication trajectory over 5-10 years
• Understand how their research evolved
• Identify patterns: what made their ideas successful?

Community Mapping

• Map collaborative networks in your field
• Identify who works with whom
• Understand which problems different groups focus on
• This helps with conference networking (see /openbs-conference)

BUILDING GOOD RESEARCH HABITS

Daily Habits

• Read at least 1 paper abstract; deep-read 2+ per week
• Write something every day (even just notes or summaries)
• Back up your work (3-copy rule)

Weekly Habits

• Update your reading list
• Prepare for group meeting with progress slides
• Review your research roadmap

Monthly Habits

• Assess progress against milestones
• Identify what's blocking you and propose solutions
• Meet with your mentor (senior labmate) for perspective

Yearly Habits

• Attend 10+ seminars
• Update your conference deadline calendar
• Reflect on your research trajectory
• Read Prof. He's Year 1 guide again (the advice evolves as you grow)

NUS-SPECIFIC AWARDS TO AIM FOR

• RAA (Research Achievement Award): 1-2 top papers in the past year gives high chance
• DGA (Dean's Graduate Award): 3-4 top papers plus strong systems/impacts -- highest distinction for PhD students at SoC, awarded only once per PhD
• Recommended trajectory: First aim for an RAA, then build toward a DGA
