Cedric Huchuan Xia
McKinsey & Company
After undergraduate work at Washington University in St. Louis, Cedric embarked on the joint M.D.-Ph.D. program at Penn with the Neuroscience Graduate Group. His thesis work, co-advised by Dani Bassett, broadly focused on understanding heterogeneity of psychiatric disorders and brain connectivity by marrying big data in neuroimaging (Xia et al., 2018, Nature Communications) with machine learning tools (Xia et al., 2020, Human Brain Mapping). Most recently, his third first-author paper with the lab ventured into delineating individual differences using smartphone based digital phenotyping (Xia et al., 2021, under review). With a passion for breaking down complex stories with data visualization, Cedric closely collaborated on more than fifteen other projects in the lab as a co-author and contributed art work to the covers of Biological Psychiatry twice. His work was recognized by the Blavatnik Fellowship as well as multiple merit travel awards, including those from the American College of Neuropsychopharmacology, Society of Biological Psychiatry, and Organization on Human Brain Mapping. During his time at the lab, he also furthered international collaborations with exchanges at academic institutions in France and Germany (and met his future husband while at it.) Earning an M.D. and a Ph.D. in 2021, Dr. Xia is pressing ahead with his career adventure combining medicine, tech, and business. He is currently an associate at McKinsey & Company in Los Angeles, California.
After undergraduate work at Cornell and a two year stint as an NIMH IRTA, Graham completed his PhD through the Neuroscience Graduate Group. Co-mentored by Dani Bassett, Graham's work sought to use techniques from network science to understand the developing brain. He was phenomenally successful. While in the lab, he wrote three first author papers. He demonstrated that during development structural brain networks become increasingly segregated (Baum et al., Current Biology 2017). Furthermore, in a methodological paper, he showed that motion artifact can systematically bias estimates of structural brain network connectivity (Baum et al., Neuoimage 2018). Finally, he delineated that coupling between structural and functional brain networks remodels in a hierarchy-dependent manner throughout adolescence (Baum et al., PNAS 2019). In addition to these important papers, he contributed to 12 other papers in the lab, and received an NIMH F31 award. He is now a post-doctoral fellow at Harvard University in the lab of Leah Somerville.
Ted's was very lucky that his first clinical research coordinator was Lillie Vandekar. She helped him get his lab started, and ran an imaging study examining reward system deficits across psychiatric disorders. She contributed and was a co-author on three papers during her three years in the lab. She is now finishing her doctoral training to be a clinical psychologist.

Ph.D. Student in Bioengineering
Rastko Ciric was a data analyst in the lab for three years, where he was one the primary people responsible for processing the multi-modal imaging data of the Philadelphia Neurodevelopmental Cohort. To accomplish this huge task, Rastko designed and built a new image processing pipeline system – the eXtensible Connectivity Pipelines. Rastko used this system to conduct a rigorous benchmarking analysis of 14 different denoising strategies to mitigate motion artifact in studies of functional connectivity; this paper was one of the top 3 most-cited papers in Neuroimage in 2017. Subsequently, he provided further details for these procedures in a dedicated protocol paper (Ciric et al., Nature Protocols 2018). In addition to these major projects which he lead, Rastko supported (and was co-author) on an additional 13 papers. He is now a Ph.D. candidate in Bioengineering at Stanford University.
