Overview
A conference paper and a conference talk are different objects. A typical oral slot of 12 to 20 minutes can carry one research question, the essential method, two or three results and a clear implication. Presenters who try to compress the whole paper end up rushing the result the audience came for. Defense presentations have the opposite risk: candidates try to summarize every chapter and use most of the opening before reaching their contribution.
We start from the format rules and the audience. For a conference, that means the session length, whether chairs enforce time strictly, whether you present on your own laptop or a shared machine, and whether the session is hybrid. For a defense, it means your institution's format: some expect a 20 to 45 minute public lecture, others a short summary before examiner questions, and a UK-style viva may have no presentation at all. We design to those rules, not to a generic template.
Your deliverable is a deck you can present with confidence, a timing plan and a set of backup slides mapped to likely questions. For the defense itself, this page pairs with our viva and defense preparation coaching, which focuses on mock questioning and your answers.
Who it’s for and the problems it solves
This is for you if you are…
- Doctoral and master's candidates preparing the opening presentation of a thesis defense
- Researchers with an accepted abstract for an oral session, lightning talk or symposium
- Students entering a Three Minute Thesis (3MT) style competition who need one static slide and a tight script
- Early-career researchers presenting at their first international conference in English
- Invited speakers adapting a long seminar into a keynote or panel slot
Common problems we help with
- Your draft talk is 35 slides for a 15-minute slot
- You do not know how much of the literature review and methods to include in a defense opening
- You are worried about a specific weakness in your study being raised during questions
- The conference requires a slide ratio, file format or upload deadline you have not dealt with before
- You present in English as an additional language and want slides that support you if you lose your place
What’s included — and what isn’t
Included
- Reading the call, program or defense regulations to confirm length, format, question time and technical constraints
- A talk plan: opening hook, research question, method in one or two slides, key results, contribution and take-home message
- Slide-count and timing guidance based on your speaking pace, with checkpoints (for example, 'results by minute six')
- Design or redesign of the deck with assertion-evidence headlines and legible figures
- Backup and appendix slides for anticipated questions on method, limitations, robustness and alternative explanations
- Defense-specific structure: contribution statement, chapter map, what was learned since submission, corrections already identified
- Short formats: lightning talks, poster pitches and single-slide competition formats
- Hybrid and online delivery setup: camera framing, screen sharing, slide ratio and a PDF fallback
- One recorded or live rehearsal with timed feedback on pacing, clarity and slide transitions
Not included
- Answering examiner questions for you or supplying scripted answers to memorize as if they were your own thinking
- Writing new analysis or results for the defense that are not in your thesis
- Presenting on your behalf or attending the event
- Promising a pass, a prize or a positive examiner report
What you receive
- Talk plan and timing map
- A one-page plan showing each section, its slide count and the minute by which you should reach it, adjusted after rehearsal.
- Presentation deck
- Your talk in PowerPoint, Google Slides or Beamer, with speaker notes and a PDF export for the organizers' machine.
- Question bank and backup slides
- A list of predictable questions grouped by theme, each linked to a backup slide with the figure or table you would need to answer it.
- Rehearsal feedback
- Timed notes from a rehearsal covering pace, filler, transitions, slide overruns and where the audience would lose the thread.
How it works
Rules and audience
You send the call for papers, program slot or defense regulations and your paper or thesis. We confirm time, format and what the examiners or chair expect.
Storyline
We agree the single contribution you want remembered and plan the talk backwards from it, deciding what moves to backup slides.
Deck build
We design or refine the slides and draft speaker-note prompts in your words for you to adjust.
Question preparation
We list likely questions from your methods and limitations and prepare backup slides; you draft your own answers and we give feedback.
Rehearsal
You rehearse live or by recording. We time it, give feedback and make final adjustments to the deck.
Formats and techniques
- Conference oral sessions
- Usually 10 to 20 minutes plus questions; we plan roughly one to two minutes per content slide and build a hard stop before the chair's signal.
- Lightning talks and poster pitches
- Two to five minutes with a single question, one striking result and a pointer to the poster or paper.
- Three Minute Thesis style
- One static slide, no animation and a script built for a general audience; always check the current competition rules for your university.
- Defense opening presentation
- Contribution-first structure, a brief map of chapters or papers, key findings, limitations acknowledged before examiners raise them, and future work.
- Backup slide library
- Hidden or appendix slides with numbered hyperlinks from a menu slide so you can jump to the right evidence during questions.
- Hybrid delivery
- Presenter view on one screen, slides shared from a PDF fallback, microphone checks and eye contact with the camera as well as the room.
Planning backwards from the one thing you want remembered
Ask a colleague what they remember from a talk a week later and you usually hear one sentence. We start by writing that sentence for your talk, then keep only the slides needed to make it believable: the question, enough method to trust the result, the result itself and why it matters. Everything else becomes a backup slide or a pointer to the paper.
What a defense presentation needs that a conference talk does not
Examiners have read your thesis. They do not need a chapter-by-chapter summary; they want to see that you understand your contribution, its limits and how it connects to the field. A strong opening names the contribution early, shows how the parts of the thesis fit together, acknowledges the main limitation in your own words and signals what you would do next.
Formats vary widely by country and institution. North American defenses often include a public talk, many European defenses are public ceremonies with set timings, and UK vivas are usually private discussions with no slides. We check your regulations before designing anything.
Preparing for questions without scripting answers
Most questions are predictable from your design: sample size, choice of method, alternative explanations, generalizability and what you would change. We help you list them, find the evidence in your own work and build backup slides. You draft your answers, and we give feedback on clarity and completeness so that on the day you are speaking from understanding, not memory.
- Method questions → a slide with design, sample and key decisions
- Robustness questions → a table of alternative specifications or sensitivity checks you actually ran
- Scope questions → a slide on limitations and future work
What the work can look like
Illustrative example — fictional data
Illustrative talk plan for a 15-minute conference slot
A fictional PhD candidate in environmental engineering has a 15-minute oral slot (12 minutes talk, 3 minutes questions) for a paper on membrane fouling. The draft deck has 31 slides. The plan below is invented to show how a timing map works.
Timing map
Minutes 0–1.5: problem and one photo of a fouled membrane. Minutes 1.5–3.5: research question and design in two slides. Minutes 3.5–9: three results slides, each with one chart. Minutes 9–11: implication for plant operators and one limitation. Minutes 11–12: take-home slide left on screen during questions.
What moved out
Nineteen slides became backup slides: the full literature table, calibration details, two sensitivity analyses and the cost model. A menu slide links to each so they can be found in seconds.
Rehearsal note
First run took 16 minutes 40 seconds. Cutting a second method slide and speaking to the chart instead of reading the headline brought it to 11 minutes 50 seconds.

Questions people ask before starting
How many slides should I use for a 15-minute talk?
There is no fixed number, but many speakers manage one content slide per one to two minutes, so roughly 8 to 14 slides plus title and backup slides. Dense slides take longer, and a slide you only show for a few seconds usually belongs in the backup set.
Can you tell me what the examiners will ask at my defense?
Nobody can predict examiners exactly. We can identify the questions your design, methods and limitations make likely, based on your thesis and common examiner concerns, and help you prepare evidence for them.
My defense is in French but my conference talk is in English. Can you help with both?
Yes. We can work on decks in English or French and adapt slides between languages. For a full translation of slides or a thesis summary, see our academic translation services.
Do you help with the viva if there is no presentation?
In that case the preparation is about discussion and questioning, which our viva and defense preparation coaching covers. This page focuses on the talk and the slides.
What should I send if my thesis is not finished yet?
Send the latest full draft or the chapters that contain your main findings. We can plan the structure early and update the deck once your results are final.
