My research agenda concerns the areas of optimal and experimental design and survival analysis. In optimal design one determines where or when measurements should be taken in order to make the "best" inference possible from the data that will be collected. For the purpose of illustration, consider a clinical trial where 50 people are administered a blood pressure lowering treatment. Can we develop designs that will allow us to "best" estimate: (i) the proportion of people affected by the treatment, (ii) the timing of the treatment effect and/or, (iii) the before- and after-change average blood pressures. An interesting application of experimental design is in genomics. In the last 20 years many new technologies have been developed for studying our DNA and variations in our DNA that might suggest predisposition to diseases such as cancer. These experiments are often very costly hence their design is a key issue in ensuring that the best quality data possible can be collected.

我的研究议程涉及最佳和实验设计和生存分析领域。在最优设计中，人们确定在何处或何时进行测量，以便从将要收集的数据中做出“最佳”推断。为了说明的目的，考虑一项临床试验，其中50人接受降压治疗。我们是否可以开发设计，使我们能够“最佳”估计：（i）受治疗影响的人群比例，（ii）治疗效果的时间和/或（iii）改变前后的平均血压。实验设计的一个有趣的应用是在基因组学中。在过去的20年里，许多新技术已经开发出来，用于研究我们的DNA和我们DNA中的变异，这些变异可能表明我们易患癌症等疾病。这些实验通常非常昂贵，因此它们的设计是确保可以收集最佳质量数据的关键问题。
