"Research Assistant" 和"Research Associate" 的区别
推荐回答（2个）
Research Assistant 就是助研，一般是研究生或是访问学者在做，而Research Associate 级别属于 Faculty，只比 Professor 低一级，所以比Research Assistant 要高。
名称无所谓，不同国家，甚至同一个国家的不同机构称谓都会不同。关键是看，其所做工作的份量及承担的责任。
比如说有家研究所：
几年前，research associate 就是博后的样子；research fellow 是博后满三年（大概）留所后相对固定的职位。
现在，research associate 依旧，research fellow名称改 research scientist了，而以前的本科或硕士毕业叫research officer的，却改叫research fellow了，呵呵
research scientist 常常比 assistant professor的位置要低。senior research scientist 大概可以到学校拿个assistant professor的位置， 但不确定，因为后者对背景的要求很高，而且是走faculty路线的。
但是，也有很多research scientist 到某些学校拿个ajunct assistant professor 啥的（senior 就拿ajunct associate professor， 呵呵），不过感觉比较水，ajunct就以为着文章成果大家分，何乐而不为呢？要真做assistant professor 了，就会动真格了
另外的研究所，
post-doctor fellow, research fellow, research engineer 都是博后的叫法。不过，research engineer 有点区分不清：本科，硕士，甚至博后留所后也有继续叫research engineer 的。
research associate/scientist, senior research scientist都可以带博士生的，但都是替老板(有faculty身份的）带。
