How to design a prize-winning scientific poster: 10 simple steps

A scientific poster and a scientific paper are two completely different beasts. A poster should be a figure-based presentation: eye-catching and quick to scan. In contrast, the research article is a more detailed, text-based presentation of your work. Now you know what you’re trying to design, here’s how…

  1. Check the conference specification

Should the poster be A1 or A0? Portrait or landscape? Too often people check these details after they’ve designed their poster and have to totally redesign, try a quick fix, or just turn up with the wrong thing. The conference spec should be your starting point! Go on the conference website or track down the poster confirmation email.

  1. Know your deadline: contact the printer

Find out what your deadline is early on, before you design your poster. Some printers can turn around a poster in an hour, but others may take 24 hours, particularly if they are busy. Find out who can print it for you and confirm the little details. Can they print the size you need? Do you pay with a grant code or with cash? Are there different printing options? Do they need a PDF? If in any doubt, just ask. Make sure you have your poster in your hand at least the day before you travel to avoid last minute stress.

  1. Gather together all the relevant data

Put all the figures into a Powerpoint presentation or similar. Include everything that you might want on your poster, old data that helps to set the scene and the data you got last week! Don’t be afraid to include preliminary data, or surprising results. A conference is a great place to get feedback on your work, and the more data you give people, the more useful the feedback.

  1. Talk to your supervisor

Now that you have all your data gathered, show your supervisor what you want to include in your poster. They might want you to exclude certain “top secret” results, or ask you to add in extra data. Some supervisors are very particular about the formatting of posters produced in their lab, so just check if they have any requirements before you design the poster.

And, while you’re chatting, make sure to find out about costs. Will the grant cover an A0, encapsulated poster?

  1. Design the template

A picture is worth a thousand words. Don’t ignore the old adage! Design your template around the figures. And make life as easy as possible for the viewer. They should never be unsure of what to read next, so if you have a lot of data use numbers and/or arrows to help guide them. Overall, left to right progression (rather than top to bottom) is good as it means several people can read at once, shuffling sideways when they get to the next section.

Here is an example of an A0 poster layout where you have a lot of small pieces of data that you want to present. Figures (blue) dominate, but are complemented by explanatory text (green).

Here is an example of an A1 poster layout where you only have a few key pieces of data. Again figures (blue) dominate. It’s a nice touch to add an image, for example of the species you study, attracting fellow researchers to the poster! And add the crest/name of your institution beside your title!

Of course, these are just examples, there are thousands of winning combinations, but they illustrate how you can achieve clarity and a figure-dominated poster.

  1. Design the colour scheme

Create a two/three-tone background colour scheme to make the poster aesthetically pleasing. Make sure that your text is clear on whatever background you choose, so avoid text directly on a patterned background, and use very dark background with white text, or a very light background with black. Here are some examples:

For graphs, use the same colour/pattern for the same conditions throughout. Clarity is king here.

Also, remember that 1 in 12 men, and 1 in 200 women are colour-blind, so avoid red/green charts and red/green fluorescent images. Here are some good tips on designing with colour blindness in mind. Magenta/green is a much clearer alternative for fluorescent images!

  1. Insert the figures and data

Here is when your poster suddenly comes together! Try to keep your figures clutter-free. Make sure everything is labelled so that the viewer knows what they are looking at, but remember that this is not a paper. Keep labels simple and clear. I also highly recommend using a figure to illustrate an interesting method.

  1. Add essential text

Your data should be prominent, accompanied only by necessary text. Keep text large, minimum font size 24, but larger for subheadings, so that it can be read from a reasonable distance.

For more information on text formatting, check out this website. Bear in mind some of their example posters have a bit too much text for a scientific poster.

  1. Proofread and print!

It is always difficult to proofread your own work. You tend to read what you intended to write, not what is actually there. Sometimes it helps if you proofread a printed version (only a small A4 required). Do ask your supervisor, post docs or fellow PhD students in the lab to read through it, then send it to the printers!

If you do spot a mistake, don’t despair. You can always correct it with a permanent marker or print out the correction and stick it over the mistake.

  1. At the conference, engage and discuss!

This is the most important point of all. Engage with everyone who looks at your poster, “Hello, would you like me to take you through it?”. Some will be happier to read it themselves, but many people like the author to guide them. If you have designed a poster dominated by figures then it is quite natural to take someone through the poster, explaining what each figure shows. Remember it is a discussion! Find out what the viewer works on themselves, and this will let you know how much detail to go into. Conferences can be brilliant experiences! Experts in your field will be spending time looking at your work, and they can be so helpful! Bring a notebook with you, as you might want to quickly jot down any comments/suggestions as you get them, or take an email address!

Now that you know how to design your poster, best of luck! Share your finished poster with me on Twitter @labcoatlucy.

How to prepare for your PhD viva: 10 top tips

Thesis.A few weeks ago I was searching the internet for advice on how to prepare for my viva. I knew I should be doing something, but wasn’t quite sure what! After asking friends and colleagues for advice and reading a lot of websites, I figured it out. Now, I want to save you all that hassle.

Here are my top tips on how to prepare for a (science) viva voce, while it’s still fresh…

  1. Read over your thesis thoroughly!

At least a couple of weeks before the viva, read through your thesis slowly, cover to cover. Don’t be afraid to add post-it notes, and highlight to your heart’s desire. (Make sure that your copy is exactly the same as the one you gave your examiners!)

  1. Make notes in the margin

While you are rereading your thesis, if you find any areas where you feel that your understanding is a little superficial, then do some quick reading on it and make notes in the margin. It is particularly important that you know your materials and methods inside out. You should be able to explain why you did everything that you did.

  1. Prepare a list of errors.

You will undoubtedly spot a few typos, and maybe worse, when you reread your thesis. Don’t be embarrassed, just make a list and bring it with you to the viva. It shows that you’ve prepared, and your examiners will be grateful that they don’t have to waste time on boring editing. (Note: even if you find typos, don’t start editing until after your viva!)

  1. Prepare answers to your 10 nightmare questions.

This is my favourite tip! Writing down answers to the questions you don’t want to come up forces you to prepare proper, well-researched responses. The viva suddenly seems a lot less intimidating once you’ve “faced your fears”! And, if any of the questions do come up, now you have great answers. In the end I had almost 20 nightmare questions on the list. Just keep adding as you think of them!

  1. Research your examiners

Chances are that you are familiar with the research of your examiners. Make sure you reread their most relevant papers and look out for any new material. Consider how your work is relevant to their research. You are an expert in your field, so your examiners are probably genuinely interested in hearing your thoughts on how your results or methods might affect their work.

  1. Make a list of your top 20 papers.

Go through each of your chapters and list the papers that were most important to the research (standing on the shoulders of giants and all that). You might have 20-30 at the end. If you have time, write a paragraph on each, focusing on the methods and results. But remember, this viva is about your work. You are not expected to know every paper you’ve referenced inside and out. In the end, I probably didn’t need to do all of this extra work, but “the literature” is one of the things that PhD students often feel nervous about, I certainly did! Having done this preparation I felt confident that I could hold my own, and so it was definitely worth the effort. (It may vary depending on your institution, but I was allowed to bring these notes into my viva. I didn’t refer to them once, but it was a confidence booster and it meant I didn’t have that feeling of having to cram for an exam).

  1. Practice summarising your thesis aloud.

“Summarise your main findings” is a common start to the viva. It is thought to help a student settle by starting them off with something that’s easy. So make sure that you find it easy to talk about. Don’t rote learn a perfect summary, but get used to talking about your research aloud. Put on a timer to 5 or 10 minutes then try it, but don’t allow yourself to restart. Or you could practice talking about your work with friends or family. Make sure that this “easy question” is just that, and does settle you rather than startle you. (In some countries, you need to prepare a presentation for your viva. In that case, make sure you are well rehearsed. You should have given the presentation at least three times, aloud, without any breaks.)

  1. Prepare the little things.

How are you getting there? Do you need to arrange to stay with someone? What are you wearing? Organise these things a good while in advance. Google maps now lets you enter the day and time you want to arrive at a destination so you can get an idea of the traffic. This was lucky for me, as a two-hour journey took three and a half hours in the morning rush hour, but I was able to plan for it! Clothes-wise: wear something fairly smart to show respect to your examiners, but make sure that you are comfortable!

  1. Be honest.

I attended a viva preparation session run by Cambridge University for its grad students. Many of the students were worried that in a viva “we didn’t have the time” or “we didn’t have the money” were not acceptable answers, even though they were true. Your examiners are active researchers, they sometimes can’t do experiments they would like to do because of limited resources! That being said, you want to show them that you have become scientist, so don’t leave it at “we didn’t have the time”, continue on and say, “but if I had had more time, this is what I would have done…”, and if you didn’t have the money, explain that you used a cheaper method etc.

  1. Be confident.

The examiner’s job is to challenge your thesis. A good examiner will make you feel relaxed, but by their very nature vivas can feel quite confrontational. Do not take criticism personally and do not take it as a sign that the viva is going badly. All experiments have some weaknesses. If the examiner points them out, it is ok to agree but highlight how you have tried to compensate, perhaps by using other methods to show the same result. Your examiner may play the devil’s advocate or misunderstand something about your research, so if you don’t agree with them about something, explain why! This is your work, you know it best!

If you are at the point of having your viva voce, then you have already done all the hard work. The examiners just want to check that it was you who did the work presented in the thesis, that you understand what you were doing, and that you have earned your new title. Remember that you are the expert in the room. I passed my viva (last week), and you can too.
