Title: A distribution-free mixed-integer optimization approach to hierarchical modelling of clustered and longitudinal data
Abstract: We create a mixed-integer optimization (MIO) approach for doing cluster-aware regression, i.e. linear regression that takes into account the inherent clustered structure of the data. We compare to the linear mixed effects regression (LMEM) which is the most used current method, and design simulation experiments to show superior performance to LMEM in terms of both predictive and inferential metrics in silico. Furthermore, we show how our method is formulated in a very interpretable way; LMEM cannot generalize and make cluster-informed predictions when the cluster of new data points is unknown, but we solve this problem by training an interpretable classification tree that can help decide cluster effects for new data points, and demonstrate the power of this generalizability on a real protein expression dataset.

Title: Navigating Research Internships in Big Tech
Abstract: In this seminar, we will walk through the process of securing and succeeding in research internships at Big Tech companies. Together, we’ll delve into effective approaches for finding opportunities, navigating the application process, and maximizing the internship experience. Concluding with an insightful discussion on bridging the academia-industry divide, we’ll explore ways to capitalize on these internships to propel future career prospects.

What is the Biostatistics PhD/Master’s Student Seminar Series?
The series is a casual and relaxing place for Biostatistics students to informally gather roughly every other week to share research, connect with other students, give practice talks, and see what everyone else is working on over lunch, provided by the department. Some seminars are directly related to research students are doing for their degrees, but others are more generally about graduate school and the practice of statistics.
Please note that the seminars are open only to PhD students, Master’s students and postdocs in biostatistics.
