EMBL Course

Fundamentals of widefield and confocal microscopy and imaging

Overview

Course overview

Light microscopy is the most widely used form of microscopy for life science research. The correct handling of the microscope and optimising image quality (e.g. contrast, resolution) as well as experimental design according to different applications are crucial to obtain the best results.

This course will provide the participants with an overview of the basics of microscopy (light and optics, contrast techniques and imaging). The confocal part will include multicolour, 3D and time-lapse imaging as well as spectral imaging, photobleaching (FRAP, FLIP, FLAP) and photoactivation techniques. Basic image analysis tools including measurement functions, colocalisation and spectral unmixing as well as 3D/4D image processing will be covered, both in theory and practice. The course will combine lectures with intense daily hands-on practices followed by discussions.

Audience

This course is directed towards PhD students and faculty searching for instruction on light microscopy and basic image processing.

Modules/resources

  • Basics of optics and microscopy
  • Contrast methods
  • Basics of digital imaging
  • Fluorescence microscopy
  • Hands-on sessions

Financial assistance

Financial assistance

Limited financial assistance is provided by the EMBL Advanced Training Centre Corporate Partnership Programme and EMBO in the form of both registration fee waivers and travel grants. Availability is limited to participants attending on-site EMBL Courses and virtual or on-site EMBO Practical Courses in Heidelberg, and will be indicated during the motivation letter submission process.

Your place in the course is only confirmed by paying the registration fee, which is mandatory even when receiving a fee waiver.

Registration fee waiver

The fee waiver will cover the registration sum that you have paid to attend the course.

Travel grant

The travel grant will cover the cost of travel (airfare, train, bus, taxi, accommodation, visa, and/or registration fees*) and is provided up to specified caps which are normally as follows:

– up to €400 for participants travelling to an EMBL Course within Europe.

– up to €1000 for participants travelling to an EMBL Course from outside Europe.

– up to €500 for any participant travelling to an EMBO Practical Course.

– up to €1000 for any participant working in Chile, India, Singapore or Taiwan travelling to an EMBO Practical Course.

– up to €700 for any participant working in Croatia, Czech Republic, Estonia, Greece, Hungary, Italy, Lithuania, Luxembourg, Poland, Slovenia, and Turkey travelling to an EMBO Practical Course.

*Registration fees are only covered for EMBO Practical Courses

The organisers may reduce the grant cap to accommodate more participants. Recipients will be notified of their travel cap amount when they are informed of the outcome of their application. Original receipts must be provided with your signature for all costs incurred within two months of completion of travel. Scanned copies cannot be accepted.

Boehringer Ingelheim Fonds travel grant

Applies to selected courses only. Availability will be indicated during the motivation letter submission process.

This grant covers costs related to your attendance at the course (registration, travel and accommodation costs). The grant is restricted to PhD students and postdocs who conduct basic biomedical research.

Whether you are eligible to apply for a travel grant, depends on when you received your university entrance qualification (e.g. Abitur, A-Levels, High School Diploma, Final State Examination):

– for PhD and MD students, as well as graduates, the university entrance qualification must not have been obtained more than 11 years ago at the time of the envisaged course

– for postdocs, the university entrance qualification must not have been obtained more than 13 years ago at the time of the envisaged course

Application

You may apply for financial assistance when submitting your motivation letter for courses. In your application, you will be asked to answer questions regarding why your lab cannot fund your attendance and how your attendance will make a difference to your career. Application for financial support will not affect the outcome of your registration application.

For the Boehringer Ingelheim Fonds Travel Grant, there is a pre-application question during the motivation letter submission process, and if selected you will be requested to complete a standard form and documentation consisting of your travel expense estimation.

Selection

The scientific organisers will select the recipients of all financial assistance during the motivation letter selection process. Results will be announced approximately 6-8 weeks before the event start date, however for some events this may be delayed. Selection results do not impact your admission to the course. Selection is based on scientific merit, your current work or study location, the reasons for needing financial support, and the impact this event will have on your career.

Reimbursement

Costs will be reimbursed after the meeting only once a reimbursement form and original receipts (from travel costs) have been received.

Warning

EMBL wishes to warn sponsors of EMBL conferences and courses of fraudulent schemes purporting to offer sponsorship opportunities on behalf of EMBL or affiliated with EMBL officials. One current scam campaign of which we are aware is conducted using the name ‘Judy Eastman’ (judy@gopcontact.a2hosted.com) and entails approaches to sponsors offering sponsorship opportunities on EMBL’s behalf. Please be kindly advised that all relevant communication regarding sponsorship of EMBL conferences, symposia and courses is handled by EMBL directly and is sent from an official EMBL account. EMBL does not work with any external providers on sponsorship acquisition.

Please also note that:

  • EMBL never provides attendee lists for purchase. Any offers of such are fraudulent.
  • EMBL will never call or email you to ask for your credit card details or to request a payment.
  • All payments are on invoice.

Suspicious communications purportedly from, for or on behalf of EMBL should be reported to EMBL at the following email address sponsorship@embl.de.
