How to Lead a Technical Reading Group

Paper Review

Introduction

A technical reading group is a collaborative learning format where engineers, researchers, or students regularly meet to read and discuss academic papers, research publications, and technical literature. These groups bridge the gap between theoretical research and practical application, helping participants stay current with cutting-edge developments in their field while building deeper understanding through collective discussion.

When I started a technical paper reading group at Brex, I wanted to make sure I was facilitating it effectively. That's when I discovered this excellent guide by Cathy Wu from MIT, written in 2012. The paper provides practical strategies for leading productive discussions and creating an environment where everyone can learn together.

Below are my notes and highlights from the paper, organized to help anyone who wants to start or improve their own technical reading group.

The Core Mission

The primary goal of a technical reading group is simple but powerful: dive deep into technical topics, learn together, have spirited discussions about what you're reading, and connect with others who share your interests. It's not about passive consumption—it's about active engagement and community building.

Your Role as a Leader

As the leader or facilitator of a reading group, you have three main responsibilities:

  1. Curate reading material: Find papers, articles, and resources that are appropriate for your group's interests and skill level
  2. Facilitate productive discussions: Guide conversations to keep them focused and inclusive
  3. Maintain consistency: Ensure meetings happen regularly and participants stay engaged

Finding the Right Reading Material

Where do you find good technical papers to read? Here are several reliable sources:

  • Seek expert recommendations: In academic settings, professors and graduate students are excellent resources. For workplace reading groups, reach out to senior engineers or technical leads who can suggest influential papers in your field.
  • Start with canonical papers: Look for foundational papers that everyone in your field should know, or tutorial papers that provide comprehensive overviews of important topics.
  • Explore various formats: Don't limit yourself to just research papers. Important patents, thesis excerpts, and chapters from technical books can all make excellent reading material.
  • Use literature surveys: Survey papers that review and synthesize existing research are great for understanding the broader landscape of a topic.
  • Tap into personal libraries: Ask group members what papers they've found valuable in the past.

Guidelines for Selecting Papers

When choosing what to read, keep these principles in mind:

  • Match the skill level: Select readings that align with the prerequisites and background knowledge you've established for the group. Papers shouldn't be so advanced that they're impenetrable, nor so basic that they're boring.
  • Consider length and meeting time: For a 1.5 hour meeting, aim for papers between 8 and 40 pages. Shorter meetings require shorter papers—for a 30-minute session, you might focus on specific sections or shorter articles. (At Brex, we treated our reading group as an accountability mechanism as much as a learning tool, keeping meetings brief.)
  • Prioritize breadth over depth: Select papers that provide good overall coverage of your subject area. It's better to understand the landscape of a field than to become experts in one narrow corner of it.
  • Look for significant contributions: Most readings should either discuss particularly important results in your field, or be survey/review papers that provide broad overviews of topics.
  • Value clear methodology: Choose papers that thoroughly explain their methods. Papers that are too cryptic about their approach will frustrate readers and stifle discussion.
  • Solicit feedback: Regularly ask your group for input on paper selections and invite suggestions for future readings. This keeps everyone invested and ensures diverse perspectives.

Facilitating Productive Discussions

Running an effective discussion is both an art and a science. Here are practical strategies to make your meetings engaging and valuable:

Understanding Participation Dynamics

First, set realistic expectations: in any reading group, roughly 50% of participants will be actively engaged, 20% will contribute occasionally, and 30% may rarely speak up. This is normal, and your facilitation techniques can help improve these ratios over time.

The Secret Weapon: The Question Board

Here's the most powerful technique for successful reading groups: At the start of each meeting, have every participant write down 2 questions about the paper on a whiteboard (or shared document for virtual meetings).

Why does this work so well?

  • It gives everyone a stake in the discussion—they want their questions answered
  • It normalizes not understanding everything (which everyone experiences but few admit)
  • It ensures participants read carefully enough to formulate questions
  • It provides a ready-made agenda for your discussion

This simple practice transforms passive readers into active participants and is, according to Cathy Wu, the secret to making reading groups work.

Discussion Flow and Structure

  • Start with the big picture: Begin by discussing what the paper is about overall and what problem it's trying to solve. This ensures everyone has the same foundation before diving into details.
  • Follow the paper's structure: Generally move from the beginning to the end of the reading. This "lexical order" helps everyone stay oriented and ensures you don't skip important context.
  • Manage the pace: Keep an eye out for discussions that wander off-topic or aren't making progress. It's okay to redirect the conversation or move to the next question.
  • Respect time boundaries: Try to cover the entire reading within your scheduled time, and respect that people have other commitments when time is up. However, if there's strong interest in continuing, allow for extended discussion.

Creating an Inclusive Environment

  • Encourage broad participation: Actively invite quieter members to share their thoughts. Sometimes a simple "What do you think about this, [name]?" can draw someone into the conversation.
  • Prevent domination: Make sure no single person (including yourself as the facilitator) monopolizes the discussion. Politely redirect if needed: "That's a great point—let's hear from others too."
  • Promote thoughtful questions: Celebrate questions that lead to deeper insights and further discussion. These are the moments when real learning happens.
  • Use silence strategically: An awkward silence? That's your signal to move on to the next question on the board.

Practical Tips

  • Keep reference materials handy: Have a laptop available to look up unfamiliar concepts, related papers, or background information the group needs.
  • Bring in experts when helpful: If a particular topic would benefit from expert insight, consider inviting someone with specialized knowledge to join that session.
  • Close with reflection: End each meeting by asking what people thought of the paper. This generates useful feedback and helps with future paper selection.

Common Challenges and Solutions

Even well-run reading groups encounter obstacles. Here's how to address the most common ones:

Lack of Direction

Problem: The group feels aimless, and discussions meander without clear purpose.

Solution: For each paper, identify a specific goal or learning objective for the discussion. Participants don't need to fully achieve this goal during the meeting, but having a target gives the discussion focus and direction. For example: "By the end of this session, we should understand the core trade-offs in this algorithm" or "Let's see if we can identify how this approach might apply to our own work."

Low Participation

Problem: Many participants remain silent, making discussions feel one-sided.

Solution: Start with slightly easier (less technical) papers to build confidence and get everyone talking. As people become more comfortable participating, you can gradually increase the difficulty level. Also, provide supplementary readings and resources to help members get up to speed with foundational concepts they might be missing.

Setting Up for Long-Term Success

To build a sustainable and thriving reading group:

  • Find a co-leader: Sharing facilitation responsibilities prevents burnout and brings diverse facilitation styles to the group.
  • Connect with a mentor: Having a professional mentor for the group (perhaps a senior engineer or professor) provides guidance and lends credibility to the endeavor.
  • Incorporate lightning talks: Have group members give short presentations on topics related to your readings. This deepens engagement and helps develop presentation skills.
