Herbert H.C. Chang ’18

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

March 18, 2023

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.

Byrne Scholar Eliza Crocker ’23 inducted into Phi Beta Kappa

January 14, 2023

Congratulations to Byrne Scholar Eliza Crocker ’23, one of 24 students who were inducted into Dartmouth’s chapter of Phi Beta Kappa in November. Crocker is pursuing a major in Computer Science as well as a minor in Mathematics. With support from Byrne funds, she spent winter term ’21 conducting a research assistantship under the guidance of Professor John Voight, learning about data collection and analysis techniques to make observations regarding the Galois groups of various Belyi maps; this led to her writing two papers and presenting her research findings to faculty and other undergraduates. During winter ’21 she also participated in our department’s Directed Reading Program with graduate mentor Alex Wilson, and gave her final DRP presentation on the topic of representation theory. Crocker is a member of Dartmouth varsity sailing, and last fall she helped the team win the 2022 Victorian Urn Trophy for the NEISA Fall Women's Championship!

Jared Duker Lichtman explains his recent proof for Numberphile

July 07, 2022

In a wonderful and popular new Numberphile video, Jared Duker Lichtman AB, AM ’18 expounds and further discusses his recent proof of the Erdős primitive set conjecture. Lichtman talks in some depth about primes and primitive sets, describing his fascination with uncovering hidden mathematical beauty and structure within an ostensibly very chaotic class of sets. When he heard about this particular Erdős conjecture during his undergraduate years at Dartmouth, Lichtman states that he “absolutely fell in love with the problem, because it’s saying that these primes are very special in a precise way... I just found this such a beautiful statement.” In a second, follow-up Numberphile video, Lichtman provides additional context for primitive sets in general and mentions some examples of related open problems. He dedicates his proof of the Erdős primitive set conjecture to his undergraduate advisor, Professor Carl Pomerance, with whom he has written several joint papers.

Former Byrne Scholar Jared Duker Lichtman proves decades-old Erdős conjecture

June 08, 2022

In February Jared Duker Lichtman AB, AM ’18, currently a Clarendon Scholar at the University of Oxford Mathematical Institute, released A proof of the Erdős primitive set conjecture, resolving a longstanding conjecture which states that the Erdős sum of the set of prime numbers is the largest of any set of primitive numbers (sets in which no number divides any other). Lichtman began working on the primitive set conjecture with his advisor, Professor Carl Pomerance, while an undergraduate at Dartmouth. Their work led to several joint papers, including The Erdős conjecture for primitive sets and A generalization of primitive sets and a conjecture of Erdős. Quanta Magazine describes his resolution of the conjecture in some detail. You may read Lichtman’s own explanation of his fascination with this topic and watch a short video in an article by the Oxford Mathematical Institute. Noted number theorist András Sárközy, who co-authored many papers with Paul Erdös, said proof of the conjecture “seemed beyond reach”; other number theorists were of similar opinion. Please join us in congratulating our alumnus on this major achievement!

Contributing to economic immigration research with math and social sciences

May 07, 2022

Byrne Scholar Maria Castro ’23, right, took on research last winter seeking to explore the ways in which the 1965 Immigration Act changed the scope of legal immigration into the US. Working with Economics professor Elizabeth Cascio, she compared countries that were impacted far more by the Act to countries largely unaffected by the new legislation. They found that after the Act, the share of unauthorized immigration grew in countries whose restrictions had expanded. “We tried to control for factors like civil wars, natural disasters, and economic disparities as we ran regressions to explore the relationship between unauthorized immigration and countries most affected by the Hart-Celler Act,” says Maria. “My research with Professor Cascio sought to contribute to economic immigration research, which remains largely unexplored.” Maria is an Economics major and LALACS minor interested in exploring research related to labor and public economics.

Studying mammalian energy metabolism with Stockholm research lab

March 11, 2022

Byrne Scholar Jacob Fyda ’22 spent two terms last year doing remote research at Stockholm’s Wenner-Gren Institute for Molecular Biosciences, investigating cellular energy metabolisms related to the genetics of thermogenesis of eutherian mammals. Working with PhD student Michael Gaudry in Dr. Martin Jastroch’s Integrative Physiology of Mammalian Energy Metabolism research group, Jacob expanded on previous work he had done in-person at the institute in Summer 2019. “Our findings helped provide additional insight into the evolution of brown adipose tissue and associated genes, with the eventual goal of applying this functional and molecular knowledge to enhance treatment of metabolic diseases, including obesity and diabetes,” says Jacob. “I am incredibly grateful for the generosity of Jack and Dorothy Byrne which allowed me to develop this relationship with the lab.” Jacob’s work in Dr. Jastroch’s group has led to his co-authorship on two papers, the second of which was published in PNAS in January 2022.

Modeling athletic performance using mathematical data science

December 06, 2021

Byrne Scholar and Mathematical Data Science major Joe Gyorda ’22, second from left, interned this summer at HALE Sports, which seeks to optimize the health and performance of athletes through analyzing somatic and biometric data. “The first team was building a computer vision model in which athletes could receive real-time feedback on various exercises (e.g., squat, pushup) to correct their form. Machine learning and body pose estimation models were implemented to analyze body position/angles and identify correct/incorrect form,” says Joe, himself a triathlete. In his second team Joe worked with longitudinal somatic survey data collected from college athletes, with the goal being to implement clustering algorithms to track athlete variables over time and using predictive models to determine which variables (e.g., energy, mood) are impacted by changes in another (e.g., sleep). “I am very grateful for the generosity of the Byrne Fund for supporting me and my work!”

Byrne Scholar Winter 2021 software engineering internship

March 31, 2021

“The 2020-2021 school year (junior year for the Class of 2022) wasn’t exactly how anybody could have predicted when my class matriculated,” says Byrne Scholar Maria Roodnitsky ’22. However, thanks to the generous Byrne gift, Maria had the opportunity to spend an off term as a software engineering intern working on improving accessibility features in an iOS application with the mobile development team at Grove Collaborative. “I never could have imagined three years ago that I would be applying my love for data science and mathematics in the technology sector,” says Maria. “Having used funding to do both hands-on research with a renowned statistician and to go work in the industry itself, I can safely say that as a result of the Jack Byrne Scholars Program, I am one step closer to knowing what I want to do post-graduation. I look forward to seeing what else is in store!”
