Information for Speakers


All talks are held in English.

Seminars should be ca. 30 minutes long including 5 minutes for questions.

Lectures and Concepts Talks should be ca. 1 hour long including ca. 10 minutes for questions.

We ask that your supervisor (for Seminars) or a post-doc (for Concept Talks) introduces you to the audience.

Talks held in the lecture hall HS2, Im Neuenheimer Feld 306, Heidelberg

An IZN technician will help the speaker prepare for their talk.

The speaker should not bring a laptop but bring the presentation on a USB stick formatted for Windows (NTFS, FAT32, exFAT) or send it to

Supported presentation formats are PowerPoint and PDF.

The talk is 'hybrid', that is in front of an audience and with a ZOOM live stream.

In exceptional cases where the introducing person cannot be present, an introduction by ZOOM can be arranged, but in person is desirable.

A LOGITECH SPOTLIGHT presenter (laser pointer, slide changer) will be provided. This will show a laser spot on both the projection screen and the presentation on ZOOM.

Talks held online only

The ZOOM platform will be used. Use the Zoom software (downloadable here), not a browser.

The IZN ZOOM host will help the speakers prepare for their talks.

A brief introduction to the Zoom controls can be given beforehand.

Use a cable connection, not WiFi.

A headset (headphones with microphone) provides the best sound quality for the other participants. Macs need a headset with a USB connection. Some USB headsets do not work well with USB multi-port adapters

Have the presentation started before sharing - if it fills your screen, show your presentation in a window:

  • Microsoft 'PowerPoint':     click the Reading View icon (looks like an open book) at the bottom of the window
  • Or:    Slide Show tab    >    Set Up Slide Show    >    Browsed by an individual (window)
  • Apple 'Keynote':     Play menu   >   Play slideshow in window
  • LibreOffice 'Impress':     Slide Show menu    >    Slide Show Settings    >    Presentation Mode: In a window
  • then:    adjust the window so it fits the presentation.
  • The presentation might need a mouse-click to make it respond to the keyboard arrow keys.

If you prefer to use Presenter mode so that you can see your notes and the next slide, in Zoom go to Share Screen > Advanced > Portion of Screen and move the selection frame to fit around the area to be shared.

To share videos, the following in the Share Screen window should be activated:

  • 'Optimize for video clip' to improve the smoothness of the video BUT it lowers the quality of the presentation text, so should only be activated if needed.
  • 'Share computer sound' (if the video has sound).
