　　怎么申请杜克大学生物统计系博士?

　　杜克大学生物统计系提供五年博士学位，期间所修读的课程包括核心和选修课程，前间核心课程详细介绍了流行病学研究的原理。贯穿整个课程的是生物统计学家面临的利益冲突情况的例子，以及可重复研究的原则和实施策略。一般招收生物学相关或者具备高定量课程基础的硕士和本科学位。

　　第一步：首先，具备相关的先修课程基础和专业背景：定量课程、微积分和分析类课程背景

　　来自杜克大学生物统计学博士官网说明：

　　Some of the traits associated with success in our program are problem definition, problem solving, quantitative thinking, critical thinking, communication, intellectual curiosity, and dedication. Regarding training, a mathematical background is particularly important.

　　Students will need proficiency in both single-variate and multi-variate calculus and linear algebra. Specifically, incoming students should have a working knowledge of:

　　Optimization of functions

　　Inverse functions

　　Sequences, series and convergence, Taylor series

　　Convergence of sequences of functions (pointwise, uniform, in measure)

　　Differentiation and integration of single- and multi-variate functions

　　Fubini's theorem

　　Fundamental theorem of calculus

　　Matrix algebra and vectors

　　Vector spaces, metric spaces, Hilbert spaces

　　Linear operators

　　Spectral theorem and diagonalization of matrices

　　Inner products, quadratic forms and projections

　　A course in real analysis is strongly recommended. As curricula can vary, please note that a suitable course would cover the following (in addition to the usual topics in derivatives and integrals):

　　Real and complex number systems

　　Basic point-set topology (compactness, continuity, connectedness)

　　Metric spaces

　　Numerical sequences, convergence, Cauchy sequences

　　Sequences and series of functions

　　For an example text, please see Rudin's “Principles of Mathematical Analysis” (known as 'Baby Rudin').

　　第二步：再次基础上，满足以下几项入学要求

　　在线申请表A completed on-line Graduate School application

　　本科成绩Transcripts from all undergraduate and graduate institutions where you earned (or will earn) a degree, studied for one semester or more, or took classes that relate to your current application for graduate study

　　3封推荐信Three letters of recommendation

　　目的陈述Statement of purpose

　　入学考试成绩Graduate Record Examination (GRE) scores are not required for students applying to the PhD in Biostatistics Program for Fall 2023 matriculation. Additional information about the Duke University Graduate School application may be found at the Graduate School application website.

　　语言成绩Test of English as a Foreign Language (TOEFL) score (If applicable) or International English Language Testing System (IELTS) score (If applicable) or the Duolingo English Test score

　　第三：注意啦!最好在截止日期前递交所有材料

　　一般开启申请渠道的是9月1日，仅限秋季学生，截止日期在12月1日。
