Tzu-Yu (Joyce) Liu is currently a Simons Postdoctoral Fellow in the Departments of Mathematics and Biology at the University of Pennsylvania and affiliated with the Electrical Engineering and Computer Sciences (EECS) department at the University of California, Berkeley, working with Professor Yun S. Song. Prior to her current position, Tzu-Yu received her B.S. from the National Taiwan University (2007) and her Ph.D. from the University of Michigan, Ann Arbor (2013), both in Electrical Engineering. Her Ph.D. research was in the area of statistical signal processing, under the supervision of her advisor Professor Alfred O. Hero III, and was co-advised by Professor Clayton D. Scott.

She is a researcher in machine learning and computational biology. Her research includes statistical learning from highdimensional and small sample size problems, optimization, structured variable selection, density estimation, functional data analysis, convolutional neural network and their applications to biomedical data. These research experiences involved analysis of large datasets, e.g., genomic sequencing data, 3D/4D microscopy images, 3D human faces, and time series of electrocardiograms.
