Neuroscience Ph.D. Student
Post-lab Position:
Post-doctoral Fellow
Stanford University
Current Position:

Adam joined the lab in August of 2018 as a neuroscience PhD student, and quickly became an absoltuely essential member of the team. His first paper in the lab examined the utility of multi-shell diffusion models (Pines et al., Developmental Cognitive Neuroscience 2020). Pivoting from dMRI to fMRI, he next charachterized how coupling between person-specific, multi-scale functional networks re-organize in development (Pines et al., Nature Communications 2022). Finally, his last major project mapped how functional propagations align with the cortical heirarchy and evolve in youth (Pines et al., bioRxiv 2022).

Hamsi Radhakrishnan
2022-2023

Postdoctoral Fellow
Post-lab Position:
Senior Scientist
Penn ADRD & FTD Centers
Current Position:
Same
Hamsi grew up in Columbus, Ohio, and later in Bangalore, India, where she got her bachelor's degree in biotechnology engineering.

So she moved to Irvine, California, to get her PhD under the guidance of Dr. Craig Stark. In grad school, her thesis focused on using diffusion MRI to study aging and disease-related microstructural changes in gray matter. In her post-doc at Penn LINC, Hamsi focused on the development of advanced compressed-sensing diffusion spectrum imaging (Radhakrishnan et al., bioRxiv 2023).

M.D.-Ph.D. Student
Post-lab Position:
Associate
McKinsey & Company
Current Position:
Biotech Investor
Deep Track Capital
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.

Graham Baum
2015-2019

Neuroscience Ph.D. Student
Post-lab Position:
Post-doctoral fellow
Harvard University
Current Position:
Data Scientist
Neumora Therapeutics
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.
