Organization and Goals
The Course lectures will be open to the general public and Grant Proposal discussions will be made by student with pre-assigned papers/themes. Those are open to all CNC-PhD students, not only BEB students. Who wish to attend/be evaluated (please contact the course coordinators).
Students will have access to papers that will be made available (in BEB’s page) previous to the course. Presentations should be prepared and given together.

Presentation should be prepared together and given together—one presentation, essentially. Three specific Aims is often a good number though anywhere from 2-5 can be quite reasonable. These aims should be listed in bullet point form underneath the title of the proposal. You may also employ sub-aims if you prefer (Aim 1A, Aim 1B, etc). Take care that the proposal has a sensible structure: the title should outline the major and general aim, which should be accomplished via several more specific aims, which themselves will be achieved by means of specific experiments.
The proposal should not entirely hinge on one experiment that may or may not work. The proposal should not be narrow but should address a significant issue in a deep manner, leading to a new level of understanding of that problem. A clearly defined hypothesis will help in developing your proposal. Normally grants work within the framework of a specific number of man-years to perform, anything from 3-6 man-years is most reasonable, but it is really up to you. Shorter is better, all things being equal, so that you can do justice to individual experiments. The subject matter should be related in some way to the paper assigned to the group, but does not have to be direct follow up work. Direct follow-up is OK too but make sure there are new ideas there. Do not hesitate to discuss whether a general proposal idea is appropriate with course faculty, but faculty input should be only general, they should not “fashion” the proposal actively in advance. If you wish to work on this in advance of the course meeting, you can contact them by email. Feasibility and creativity are both important in evaluating the proposal, but creativity more so. Try not to only propose familiar experiments. Consider multiple approaches for testing your hypothesis (for example, combining genetic and biochemical approaches). Prepare a powerpoint presentation outlining the proposal and diagramming some of the central experiments you propose. Consider in this powerpoint version necessary controls and pitfalls, and the significance of the project you propose. Non-presenters should discuss the merits of the proposed experiments—whether the problem is a good one, whether the experiments effectively address the problem and will give interpretable results, whether they could actually be done in practice, whether necessary controls have been provided, whether still other experiments should be considered, and, assuming that everything goes to plan, whether the information gained would deliver a significant advance in our understanding of the subject matter.
