What is a scientific presentation?

A scientific presentation is a talk or poster where you describe the findings of your research to others. An oral presentation usually involves presenting slides to an audience. You may give an oral scientific presentation at a conference, give an invited seminar at another institution, or give a talk as part of an interview. A PhD thesis defense is one type of scientific presentation.

What is the objective of a scientific presentation?

The objective of a scientific presentation is to communicate the science such that the audience:

• Learns something new;
• Leaves with a clear understanding of the key message of your research;
• Has confidence in you and your work;
• Remembers you afterward for the right reasons.

Why is giving scientific presentations necessary?

As a scientist, one of your responsibilities is disseminating your scientific knowledge by giving presentations. Communicating your research to others is an altruistic act, as it is an opportunity to teach others about your research findings, and the knowledge you have gained while researching your topic.

• Having the opportunity to share your ideas and to have insightful conversations with other scientists. For example, a thoughtful question may create a new direction for your research.
• Gaining recognition for your work and generating excitement for your research program can help you to forge new collaborations and to obtain more citations of your papers. It's your chance to impress some of the biggest names in your field, build your reputation as a scientist, and get more people interested in your work.
• Improving your future employment prospects by getting presentation experience in high-stakes settings and by having talks listed on your academic CV.

How to give a scientific presentation

You might have just 10 minutes for your talk. But those 10 minutes are your golden ticket. To make them shine, you'll need to put in some homework. You need to think about the story you want to tell, create engaging slides, and practice how you're going to deliver it.

Why all this effort? Because the rewards are potentially huge. Imagine speaking to the top names in your field, boosting your visibility, and getting more eyes on your work. It's more than just a talk; it's your chance to showcase who you are and what you do.

Here we share 5 tips for giving effective scientific presentations.

1. Prepare adequately for your talk on the days leading up to it
2. Deal with presentation nerves
3. Deliver your talk with intention
4. Be adaptable
5. Conclude your talk with confidence

Tip 1: Prepare during the days leading up to your talk

You should prepare for your talk with the seriousness it deserves and recognize the potential it holds for your career advancement. Here are our suggestions:

• Rehearse your talk multiple times to ensure smooth flow. Know the order of your slides and key transitions without memorizing every word. Practice your speech as though you are discussing with friendly and attentive listeners.
• Record your speech and listen back to yourself giving your talk while doing household chores or while going for a walk. This will help you remember the important points of your talk and feel more comfortable with the flow of it on the day.
• Anticipate potential questions that may arise during your talk, write down your responses to those questions, and practice them aloud.
• Back up your presentation in cloud storage and on a USB key. Bring your laptop with you on the day of your talk, if needed.
• Know the time and location of your talk. Familiarize yourself with the room, if you can. Introduce yourself to the moderator before the session begins.
• Giving a talk is a performance, so preparing yourself physically and mentally is essential. Prioritize good sleep and hydration, and eat healthy, nourishing food on the day of your talk. Plan your attire to be both professional and comfortable.

Tip 2: Deal with presentation nerves by practicing simple exercises

It’s natural to feel nervous before your talk, but you want to harness that energy to present your work with confidence. Here are some ways to manage your stress levels:

• Remember that your audience want to listen to you and learn from you. Believe that your audience will be kind, friendly, and interested, rather than bored and skeptical.
• Breathing slow and deep before your talk calms the mind and nervous system. Psychologist Amy Cuddy recommends practicing open, confident postures while sitting and standing to help you get into a positive frame of mind.
• Fight off impostor syndrome with positive affirmations. You’ve got this! Remember that you know more about your research than anyone else in the room and you are giving your talk to teach others about it.

Tip 3: Deliver your talk with intention

Giving your talk with confidence is crucial for your credibility as a scientist. Focusing on your delivery helps ensure that your audience remembers and believes what you say. Here are some techniques to try:

• Before beginning, remember your professional goals and the benefits of giving your presentation. Start with a smile and exhale deeply.
• Memorize a simple opening. After the moderator introduces you, pause and take a breath. Welcome the audience, thank them for coming, and introduce yourself. You don’t need to read the title of your talk. But briefly, say something like, “today I’m going to talk to you about why [topic] is important and [what I hope you will learn from this talk]” in 1-2 sentences. Preparing your opening will settle your nerves and prevent you from starting your talk on a tangential topic, ensuring you stay on time.
• Project confidence outwardly, even if you feel nervous. Stand up tall with your shoulders back and make eye contact with individuals in the audience. Move your focus around the room, so everyone in the audience feels included.
• Maintain open body language and face the audience as much as possible, not your slides.
• Project your voice as much as you can so that people at the back of the room can hear you. Enunciate your words, avoid mumbling, and don’t trail off awkwardly.
• Varying your vocal delivery and intonation will make your talk more interesting and help the audience pay attention, particularly when you want to emphasize key points or transitions.
• Pausing for dramatic effect at crucial moments can help you relax and remember your message, as well as being an effective engagement device.
• A laser pointer can be off-putting for the audience if you are prone to having a shaky hand when nervous. Use a laser pointer only to emphasize information on the slide while providing an explanation. If you design your slides thoughtfully, you won’t need to use a laser pointer.

Tip 4: Be adaptable and willing to adjust your presentation

Not all parts of your talk may go according to plan. Here are some ways to adapt to hitches during your talk:

• Handle talk disruptions gracefully. If you make a mistake, or a technical issue occurs during your talk, remember that it’s okay to skip something and move on without apologizing.
• If you forget to mention something but the audience hasn’t noticed, don’t point it out! They don’t need to know.
• As you give your talk, be time-conscious, and watch the moderator for signals that the time is about to expire. If you realize you won’t have time to discuss all your slides, skip the less important ones. Adjust your presentation on the fly to finish on time, prioritizing content as needed.
• If you run out of time completely, just stop. You don’t have to give a conclusion, but you do need to stop on time! Practicing your talk should prevent this situation.

Tip 5: Conclude your talk and manage questions confidently

The ending of your talk is important for emphasizing your key message and ensuring the audience leave with a positive impression of you and your work. Here are some pointers.

• Conclude your talk with a memorized closing statement that summarizes the key take-home message of your research. After making your closing statement, end your talk with a simple “Thank you”. Then pause and wait for the applause. You don’t need to ask if the audience has questions because the moderator will call for questions on your behalf.
• When you receive a question, pause, then repeat the question. This ensures the whole audience understands the question and gives you time to calmly consider your answer.
• In a talk on attaining confidence in your scientific presentations, Michael Alley suggests that if you don’t know the answer to the question, then emphasize what you do know. Say something like, “Although I can’t fully answer your question, I can say [this about the topic].”
• Approach the Q&A with interest rather than anxiety by reframing it as an opportunity to further share your knowledge. Being curious, instead of feeling fearful, can help you shine during what might be the most stressful part of your presentation.

Concluding thoughts

Communicating your research effectively is a key skill for early career scientists to learn. Taking ample time to prepare and practice your presentation is an investment in your scientific development.

But here's the good part: all that effort pays off. Think of your talk as not just a presentation, but as a way to show off what you and your research are all about. Giving a compelling scientific presentation will raise your professional profile as a scientist, lead to more citations of your work, and may even help you obtain a future academic job.

But most importantly of all, giving talks contributes to science, and sharing your knowledge is an act of generosity to the scientific community.
