1 Effective poster and oral presentations AJ Frew University of Southampton, UK

2 Purpose of poster To show work and excite comment To generate advice for future work To obtain feedback for writing up To make a mark and solicit collaboration

3 Horses for courses Different layout and content needed for –Fully attended poster –Poster discussion symposium –Unsupported poster Consider providing paper copies Have the organisers arranged for electronic/CD collection of posters?

4 Key components Abstract Title Context/ Introduction Figures Summary Discussion points

5 Abstract Advertisement of work Basis of selection for display Attracts viewers May be citable and attract interest after meeting

6 Title Also attracts viewers Must be legible from distance Clear message

7 Context/Introduction Explains why study was done Limited amount of background Include hypothesis being tested Avoid excessive amounts of text

8 Methods Use photographs where possible Essential detail only (unless purpose of poster is to show a new method) Use large font Use space

9 Local Allergen Challenge baseline 10 minutes

10 Results Just key results Figures preferable to tables Supply full legends Logical sequence of experiments/data Consider summary with linking lines Logical layout, using board space to best effect

11 Title Authors Institution Abstract Intro/ Context Method Results 1 Summary Disc’n Points Legend Results 2 Legend Results 3 Legend Results 4 Legend Funding

12 Title Authors Institution Abstract Intro/ Context Method Results 1 Summary Disc’n Points Legend Results 2 Legend Results 3 Legend Results 4 Legend Funding

13 Summary Cogent summary Fair & accurate conclusions Discussion points –to excite comments and interest –to help with further experiments –to help with writing up paper

14 Role of presenter To engage with passers-by To answer queries To receive feedback Aim is to use time for discussion, not to explain methods repeatedly!

15 What makes a good poster? Clarity of purpose Appropriate use of figures and legends Small amount of legible text Enthusiastic presenter

16 Purpose of oral presentation To show work and obtain feedback for writing up To make a mark OPs are less useful than posters for: –getting comments and feedback –getting advice for future work –getting future collaborations Few questions, and usually simple ones

17 Before starting How long have I got? How much time is allocated for discussion? Who is the audience? What are the main results/points? –(one sentence summary)

18 How many slides? Aim for one slide per minute –More is possible but may appear rushed –Two per minute will always be too many Audience need time to orient themselves You will usually remember some extra things that you want to say Allow time for changeover and thanks to organisers etc

19 Key components of an oral presentation Context/ Introduction Method Results Summary Discussion points

20 Context/Introduction One slide to explain why study was done Include hypothesis being tested Avoid excessive amounts of text Avoid long explanation of “iconic” cartoon Consider highlighting the area of interest

21 cell cytoplasm membrane NF-  B IL-8 MAPK DEP TGF  heparin-binding-EGF amphiregulin MMP EGFR pro-ligand eg TGF  Autocrine ligand EGFR Mucins P P nucleus

22 Methods How much do you really need to show? Use photographs if appropriate Essential detail only (unless primary purpose of presentation is to show a new method)

23 Which works better?

24 Methods Diesel exhaust was generated from an idling Volvo engine (built 1993), diluted with filtered ambient air and pumped into an exposure chamber in the next room. On control days the engine was left running but only filtered air was supplied to the chamber Particulate and gas concentrations were measured on a continuous basis

26 Diesel engine testbed (National Inst of Working Life, Umeå)

27 Diesel exposure chamber (National Inst of Working Life, Umeå)

28 Results Identify key results and stick to them Avoid data tables Avoid figures from papers Prepare figures to show key points

29 Results -common faults This is a very busy slide, but if you look over here in the corner you can see….. As you can clearly see….. I’m sorry. I made this slide for another meeting, but if you ignore this part of the graph…… Some of you at the back may not be able to read this

30 Laser Pointers/Highlights Use laser pointer sparingly Support your wrist Don’t “hosepipe” Consider using powerpoint features to draw audience to your key points: e.g. –ring highlights –building up graphs

41 For complex built-up figures, make whole figure, then make copies and delete parts

42 Summary Bullet points only Discussion points –to acknowledge weaknesses –to compare with previous knowledge –to excite comments and interest –to help with writing up paper

43 Acknowledgements Can take a long time Often excessive Often uses up a large proportion of discussion time –especially if your presentation or the whole session is running late Consider giving acknowledgements at beginning (as part of title slide)

44 Oral presentation Plan to use your time wisely Leave time for discussion Prepare clear figures to show results Use powerpoint features, –but don’t overdo it Speak slowly - “Less is more” Give audience some ideas for discussion Rehearse with an honest friend
