Congratulations, Armin! So happy for you.

5/ I’m so grateful for everyone who contributed to this amazing project (the incredible @bogglerapture.bsky.social and team) and am so excited to see it out in the world.

4/ Our newly published methods offer new insights into X- and Y-chromosome dosage effects on behavior, and our shared code (github.com/bellalarsen1...) can now be applied to other clinical groups of interest.

3/ Our methods capture coordinated group differences in the pairwise coupling between measures of psychopathology: XXY/KS shows greater coherence among externalizing, internalizing, and autism-related features, while XYY shows greater coherence in dissociality & early neurodevelopmental impairment.

2/ Comparing nodal degree of 53 psychopathology scales (A) and fingerprints of connectivity (B), we find that social problems and externalizing symptoms are most differentially coupled to other aspects of psychopathology in XXY/KS versus XYY.

1/ Excited to share our paper, published in Psychological Medicine, addressing this question in two neurogenetic conditions involving carriage of an extra X- (XXY/Klinefelter Syndrome) vs. Y-chromosome (XYY Syndrome). doi.org/10.1017/s003...

Network analysis offers new insights into psychiatric symptoms. How can we use these tools to compare symptom patterns across groups?

Armin Raznahan @bogglerapture.bsky.social fantastic talk tracing neurogenomic disorders across human phenotypes–Studying groups not based on diagnosis but on them carrying genetic variants

I’m beyond excited to share that I’ll be starting my PhD in Cognitive Psychology at Yale this fall with support from the NSF GRFP! I feel deeply grateful to be joining this community and to work with @robbrutledge.bsky.social and the Rutledge lab!
