Herbert Chang ’18 is lead author of study published in PNAS Nexus

Former Byrne Scholar Herbert Chang ’18, Mathematics professors Feng Fu and Dan Rockmore, and Sociology professor Brooke Harrington have co-authored a new paper applying network science to the connections between wealth managers and their affluent clients. Published in the journal PNAS Nexus, their paper titled Complex systems of secrecy: the offshore networks of oligarchs explores “a new approach to targeting economic sanctions — a vital non-military tool in disputes among nations.” Chang, who has previously co-authored several papers with Professor Fu, carried out the study’s calculations and data visualizations. He is currently a PhD candidate at the University of Southern California with his primary research areas being polarization on social media, misinformation dynamics, and how algorithms reshape human behavior. We are pleased to welcome him back to Dartmouth in Fall 2023 as an Assistant Professor of Quantitative Social Science! “I’m excited to teach QSS 20: Modern Statistical Computing,” says Chang. “My principal goals are to help students develop a strong foundation in data science (suitable for further graduate study and industry) and discover a personal, social scientific core.” Read more about their study in Dartmouth News, and please join us in welcoming our alumnus back to Dartmouth this fall.

Outreach

Math Department to host Sonia Kovalevsky Day, Saturday April 22, 2023

We are happy to host our 10th annual Sonia Kovalevsky Day on Saturday, April 22, 2023. SK Day is a fun-filled day of mathematics with hands-on workshops and talks for middle and high school female students and their teachers. Originally started and funded by the Association for Women in Mathematics, the purpose of the day is to encourage young women to continue their study of mathematics and to assist the teachers of female mathematics students. The Dartmouth Math Department hosts this event annually with the goal of inspiring young students to pursue degrees in the mathematical sciences and to honor female mathematicians such as Sonia Kovalevsky, who paved the way with her groundbreaking work and was a strong proponent of higher education for women. We are delighted to hold this empowering event in person once again. Join us for a day of networking, mentoring, and fun!

Graduate Students

Interning in autonomous sensing at the ATR Center

This past summer graduate student Dylan Green interned in the Autonomy Technology Research Center Summer Program at Wright State University, a 14-week program focusing on Air Force topics related to autonomous sensing. “My summer internship at the ATR Center provided me with the opportunity to collaborate with Air Force Research Laboratory researchers as well as other students from across the country on important problems facing the military today,” says Green. “It was an invaluable experience that helped me expand my research interests and develop new skills that I will use throughout my career.” Green, a fourth year PhD student working with Professor Anne Gelb, is interested in the overlap between imaging sciences and uncertainty quantification, with his recent work focusing on 2D and 3D SAR image reconstruction techniques. He is a member of Professor Gelb’s Sea Ice Modeling and Data Assimilation (SIMDA) group, a DoD Office of Naval Research MURI program, and has been a graduate student mentor in our department’s Directed Reading Program, guiding students on the topic of mathematical foundation for synthetic aperture radar.
