Despite the benefits, researchers can face several challenges:
1. Highly Competitive: The application process is highly competitive, with many more applicants than available funds. 2. Stringent Review Process: Proposals must meet high standards of scientific rigor and feasibility. 3. Funding Limitations: Grants often come with specific restrictions on how the funds can be used. 4. Time Constraints: Preparing a high-quality research proposal can be time-consuming.
