Department of Biostatistics Welcomes 3 New Faculty


The Johns Hopkins Department of Biostatistics is excited to welcome three new faculty members this summer and fall. 

These outstanding scholars have a wealth of knowledge and experience they are bringing to the Department, along with diverse research and teaching interests. “Each of these individuals will greatly enrich our community and I look forward to welcoming them,” says Biostatistics Chair Elizabeth Stuart, PhD.

Yiqun Chen, PhD, is currently a Data Science Postdoctoral Fellow at Stanford University, working with Professor James Zou on applying advanced AI techniques to biomedical data. He received his PhD in Biostatistics from the University of Washington, advised by Professor Daniela Witten. His research interests include applying generative AI methods to biomedical data analysis and quantifying the resulting uncertainty. He has led projects in different fields of data science from dermatology, social networks and epidemiology to human-computer interaction and microbiome science. Chen will be starting January 1 as an Assistant Professor.

Daniel Obeng, ScM ’11, is returning to the Department from Flatiron Health where he worked as Director in the Research Sciences department. He has previously taught in Johns Hopkins University’s undergraduate public health studies program and for the Graduate Summer Institute of Epidemiology and Biostatistics, where he has received wonderful student feedback. "Professor Obeng is amazing! He clearly explains the material, ensures students understand the content and makes the learning experience fun," a student from 2022 wrote. Obeng will start in July as an Associate Scientist. In addition to teaching, he will be working with the Johns Hopkins Biostatistics Center.

Jessie Tong, PhD, recently completed her PhD in Biostatistics at the Perelman School of Medicine at the University of Pennsylvania. She has expertise in evidence synthesis and clinical evidence generation, particularly federated learning. Her research interests span clinical evidence generation using data from distributed research networks, surrogate-assisted semi-supervised learning, and systematic reviews and meta-analyses. Tong will start in August as an Assistant Professor.
