Scammers posing as conference organisers have previously contacted our speakers offering hotel and travel bookings, and requesting credit card details. We do not organise hotels or travel for participants, and we will never ask for payment details by email or phone. The only official ways to pay are via our Registration page or by bank transfer against an official invoice issued from [email protected], payable to “STEMM Global Scientific Society” — CRISTMas is organised by the STEMM Global Scientific Society, a not-for-profit organisation registered in the UK. All official correspondence comes from [email protected]. If you receive a suspicious email, do not reply or click any links — please forward it to [email protected] so we can warn others, and block the sender.
Each contributed talk is allocated 15 minutes, including questions. We recommend preparing a presentation of around 12 minutes, leaving 3 minutes for discussion. Session chairs will keep strictly to schedule out of fairness to all speakers. Invited and keynote speakers will be informed of their allocated time individually.
Presenting your slides. You may either bring your presentation on a USB drive and use the computer provided in the session room, or connect your own laptop. If using the on-site computer, please bring your slides as PowerPoint (.pptx) or PDF. If your presentation includes videos or non-standard fonts, please embed them in the file or bring your own laptop. If connecting your own laptop, please bring any display adapter your machine requires.
Before your session. Please arrive at least 10 minutes before the start of your session to upload your presentation or test your laptop connection, and to introduce yourself to the session chair.
Your session, room and presentation day will be confirmed in the final programme. If you have a strong preference regarding your presentation day, please let us know when you register.
