Research
My research focuses on performance modeling: developing mathematical solutions that predict system performance and inform system design. While my work is largely theoretical, I draw my research topics from the problems that arise in practice in computer systems. One common performance metric is latencythe time from when a job arrives to the system until it completes serviceand providing low latency is a key goal of most systems. To do this, we need to answer questions such as "how many servers does our system need?", "how should we dispatch jobs to servers?", and "in what order should we schedule jobs to run?" My work involves designing dispatching and scheduling policies and mathematically analyzing these policies to predict their performance. One of my particular interests is in developing theoretical models of computer systems that accurately capture important features of real systems without sacrificing analytical tractability.
