Presenters are expected to print and post their own posters. Posters will not be printed by CLEO, a printed version will need to be supplied by the presenter. They are also encouraged to upload the PDF of their poster as supplemental material, which will be posted along with their published paper. 

Presenters MUST present on-site in order to be published.    

Poster Preparation 

Posters should be readable by viewers five feet away and must display the paper title, authors, and affiliations. The message should be clear and understandable without oral explanation. Below are general guidelines to enhance the effectiveness of your poster. 

• Initial Sketch. Experiment with different styles of data presentation to achieve clarity and simplicity. 

• Rough Layout. Enlarge your best initial sketch, maintaining the proportions of the final poster. The rough layout should be full size. Print the title and headlines, indicate text with horizontal lines, and draw rough graphs and tables. This will help you gauge proportions and balance. If working with an artist, show the layout to colleagues for feedback. This is still an experimental stage. 

• Balance. Figures and tables should cover slightly more than 50% of the poster area. If you have only a few illustrations, make them large. Keep the text brief but do not omit it. The poster should be understandable without oral explanation. 

• Simplicity. Avoid overloading the poster. More material can lead to less effective communication. Prepare a 6-inch high headline strip running the full width of the poster, including the title, authors, and affiliations in letters at least 1 inch high. Post a large typed copy of your abstract. 

Poster Template 

There is no official poster template for CLEO. However, there are several companies that offer free templates to assist you in creating your Poster PDF. The A0 poster size formatted vertically is the most popular based on the physical dimensions of boards provided on site.

Presenters should display paper titles, lists of authors and author affiliations on their posters. Posters will not be printed by CLEO, a printed version will need to be supplied by the presenter. 

On-site Presentation 

Please note that poster papers are not supplied with electricity or audiovisual equipment. For 2026, an eight-foot-high x four-foot-wide (approximately 244 cm x 122 cm) board will be supplied.  You will also be provided with a sign indicating your paper number and pushpins. 

All poster presenters are to post their presentations on their assigned boards during the setup time above. Presenters must be standing adjacent to their boards during their assigned poster session. 

Important Information for CLEO 2025 Oral Presenters
All presenters must arrive 15 minutes prior to the start of their session—not their individual presentation time. For example, if your session begins at 1:00 PM, but your talk is scheduled for 1:45 PM, you are still required to arrive by 12:45 PM.
You are responsible for bringing your presentation on a USB thumb drive. During the 15-minute pre-session window, you will:
• Meet with the session presider to confirm the pronunciation of your name.
• Upload your presentation to the session room computer.
Presenters are not permitted to use their own laptops. All presentations must be run from the session room computer. Uploading your file in advance ensures a smooth transition between talks and avoids technical delays.
If you encounter any technical issues prior to your session, please visit the Technical Session Support Desk. Staff will be available to assist with troubleshooting and ensure your presentation is ready.

PRESENTATION GUIDELINES: 

All presentations will be held in Microsoft PowerPoint on a PC running Windows. Presentations in Acrobat PDF format, Word format, Keynote will not be accepted.    

Presentations should be formatted 16:9.  

Videos should be sent as separate files. Please do not embed them into your presentation.  

Avoid using anything smaller than 24 pt for body text, 36pt for headings 

Use a sans-serif typeface such as Helvetica, Calibri, Verdana, or Arial.  

Limit each slide to 6-7 lines of text maximum 

Use mixed case, not ALL CAPS (which is harder to read) 

Please do not use timer-controlled transitions.  

 Each session will include a presider responsible for transitioning between presenters and ensuring adherence to time restrictions. 

PRESENTATION TIPS: 

• Bold text for emphasis rather than italics or underlining 
• Maintain consistent formatting throughout the presentation 
• Left-align text for easier reading (avoid justified text) 
• Ensure adequate spacing between lines (1.5x recommended) 
• Follow the “Rule of Thirds” for visual composition 
• Include only one main idea per slide 
• Create a clear visual hierarchy through sizing and placement 
• Include slide numbers for reference 
• Leave sufficient white space around content 

All presiders are expected to be at the conference in person. We ask all presiders to check-in at least 15 minutes before your session begins to ensure each session has a designated presider, and confer with the speakers and room monitor to understand how each presentation will be delivered.  

Presiders are invited to attend our Presider Briefings, being held on Monday 5 May at 7:00am in Room 102A and Wednesday 7 May at 7:00am in Room 102A. 

At Least 3 Days Before the Conference 

Perform these steps to ensure you are prepared for your session responsibilities. 

1. Read the entirety of these instructions to familiarize yourself with the Session Presider instructions. 
2. Review your session before the meeting via the Session Host tool in ScholarOne. 
3. In the upper right-hand corner, click on Messages (New). 
4. Click on Invitations (New).
5. Under ACTION on the left, click on Select and select View & Respond.
6. Click the + next to Session Information.
7. The session details will display the final order of presentation and total amount of time allotted for each presentation. You can also use the Online Schedule or the conference app for general session information.  However, the email addresses for the speakers in your session are only available through the session host tool.  
8. Contacting presenters in advance is encouraged so that you can obtain seed questions from them and encourage live participation. Follow step #3 above to obtain the presenter emails, or contact CLEO Management staff if needed.  

At Least 15 Minutes Before the Session Begins 

Presiders will be focused on conducting the session, introducing the speakers and moderating Q&A.  

1. Arrive in your session room at least 15 minutes before the start of your session. 
2. Have the speaker order and time readily available, as it will assist you in running an effective session. You can access it through the Online Schedule, the conference app, or with the physical schedule we will have provided you in the room. 
3. Check in with the IT Help Desk and session speakers to ensure that you understand how the presentations will be delivered and/or whether there will be a live Q&A segment. 
4. If you have a question about pronouncing the names of any of the live presenters, the title of the talk or the name of their institutional affiliation, ask prior to the start of the session. It can be quite embarrassing for both you and the speaker if you pronounce something wrong. 
5. Alert the on-site speakers that questions will be asked by the audience in the room.  
6. Alert the speakers that you would like them to remain for the entire session as you may go back to them, if time allows between talks, to ask questions that may not have been addressed earlier due to lack of time. 

Starting the Session and Introducing Speakers 

1. Start the session with a few remarks. Introduce yourself and provide your affiliation. Mention the session theme. 
2. Introduce the first speaker and provide basic information about their talk.  The presenter will come to the podium to present. 
3. Manage the Q&A segment from your designated table outfitted with a computer and microphone. On-site attendees should make their way to the aisle microphone in order for the full question to be heard by all participants.  
4. For each presentation, announce the speaker’s name, affiliation and their talk title. 
5. If a speaker does not show up for the session, either allow a continuation of the discussion of any of the previous presentations or announce an intermission until the next scheduled presentation. Please do not start presentations earlier than scheduled. Attendees may be moving between sessions and planning on attending a particular talk scheduled for a specific time. 

IT Help Desk functions include: 

1. Test sharing functionality and audio-visual quality. 
2. Offer assistance to you and all speakers and answer any questions.
