The 2019 Minghui Yu Memorial Conference, organized by doctoral students in the Statistics Department of Columbia
University, will take place on
Saturday, April 27th at the
Faculty House. Minghui Yu was a doctoral student at the statistics
department, who passed away in a tragic accident in the spring of 2008. Since then, doctoral students
in the statistics department have been organizing a conference each year to honor his memory; this year will mark the 10th anniversary since the inaugural conference.
The conference will feature talks by doctoral students at the Statistics Department, ranging from those just beginning a research program to those who are about to defend dissertations. In addition to being an occasion to remember our friend and colleague, this event will be an opportunity to learn about exciting new research areas emerging from our department. We would like to thank the Department of Statistics for their continuous support.
Minghui was born in Shandong, China in 1983. In 2002, he entered the Special Class for the Gifted Young at the University of Science and Technology of China (USTC), one of the most prestigious universities in China. Minghui possessed the rare quality of being not only smart, but also diligent, versatile, modest and easy-going. He was the type of friend who would stand by you no matter the situation. Minghui breezed through the challenging undergraduate program at USTC, ranking at the top of his class. Minghui was well liked by his fellows students having served as the class president from his sophomore year. Although under enormous academic pressure, he still found time to organize a series of student activities, such as hiking, art performances, and athletic contests for his fellow students.
After graduating summa cum laude in 2006 from USTC, Minghui entered the PhD program at the Physics Department of Columbia University. After one year, he transferred to the doctorate program in statistics. During his time at Columbia, Minghui served as the public relations head of the Columbia University's Chinese Students and Scholars Association (2007-2008), and was a member of the Columbia Chinese Basketball Association and the Columbia Graduate Student Consulting Club. His biography on the CUCSSA website mentioned his love of ''movies, photography and delicacies''. Minghui described himself in his blog as ''a boy who wants to combine art and science together''.
On April 4, 2008, after attending a student-organized conference, Minghui escorted his girlfriend home on the west side of campus. On his return, he was accosted as he was crossing 122nd and Broadway and in his attempt to flee, he was struck by an automobile on Broadway. Minghui was taken to St. Luke's Hospital where he passed away a short time later.
We are excited to have two former graduates from the doctoral program in Statistics at Columbia University - Johannes Ruf and Tyler McCormick - as our keynote speakers this year. As students, both were part of the organizing committee for the inaugural Minghui conference, both received the Howard Levene Teaching Award from the department, and both held various service roles within the department.
Johannes is currently an Associate Professor in the Department of Mathematics at the London School of Economics, with his research focusing on stochastic analysis and its applications to mathematical finance. He began his education at the University of Ulm and Texas A&M University, later earning his PhD in Statistics under the supervision of Ioannis Karatzas, before becoming a Senior Research Fellow at the University of Oxford. He has also been a lecturer and a reader at University College London.
Tyler is currently an Associate Professor of Statistics and Sociology at the University of Washington, with some of his research interests being in the analysis of social networks and the estimation of demographic indicators with sparsely sampled data. He started his education as an undergraduate at Duke University, completing a masters degree at the University of Connecticut before obtaining his PhD in Statistics under the supervision of Tian Zheng, and has held various positions at the University of Washington since. He is currently the editor of the Journal of Computational Statistics and Graphics.
