Stork是我最好的科研助手(2):经费提醒

1. 我的导师是否有经费? 2. 我在寻找博后的职位;我未来的老板是否有足够的经费支持我? 3. 有多少经费拨给了我的研究领域(比如NIRS)?谁得到了这些经费?他们将用这些经费做什么? 你是否也曾考虑过这些问题?当我还是一个研究生的时候,我很少问这些关于“钱”的问题。“钱”似乎并不是一个“真正”的科学家应该在意的事。而当我得知我的导师为经费申请花着大半部分时间的时候,我更加疑惑了,他难道不应该把时间用在做实验以及撰写论文上吗? 当我开始博后研究时,我发现自己同样花费很多时间申请经费。我也逐渐意识到我的未来科研事业是否成功,很大一部分是由我是否能有足够稳定的经费支持来决定的。我见到一些同事,由于缺少经费不得不离开科研界。我想到如果能有一个工具及时提醒我当下的经费拨款情况,我的科学研究应当可以更加有的放矢。 Stork 就是这样一个工具。 我在Stork里输入如下关键字,“pearl chiu”(我之前同事的名字)以及“NIRS brain”(我的研究领域)。以下是Stork发给我的邮件: 有了Stork提供的信息,我了解了在我的研究领域,谁得到了经费以及他们打算用这笔经费做什么研究。实际上邮件里的第三个基金是拨给我的同事Manish, 用于他进行利用NIRS对静息状态下的脑回路的研究。我还看到Pearl得到了很大一笔经费,所以我给她发送了一封祝贺邮件。与Stork的另一个功能论文提醒比起来,经费提醒让我更早的对自己研究领域的趋势了如指掌。得到经费支持的研究,通常需要几年之后才有相关论文发表出来。 如果你也想变成第一个在你领域知道有哪些新经费颁发的人,快去试试Stork你一定会发现很多惊喜!
