Michael Foley

Michael's broad research interests lie in the overlap between complex systems and the social sciences. In particular, he is interested in how rational local decisions and interactions can produce unintended and emergent system behavior. Michael has a B.S. and M.S. in Mathematics from the University of Vermont, where he did research in computational finance and agent based modeling. Currently, he is working with Chris Riedl to research the effect of different communication networks on a group's ability to solve problems.

Devin Gaffney

Devin was previously a lead developer at a startup leveraging social network data in Portland Oregon. He holds a MSc in Social Science of the Internet from Oxford University's Internet Institute, and attended Bennington College for undergrad. His primary interests orbit around the information that people leave behind on the Internet, what that information can provide in explaining human behavior, and by what methods can this data be interrogated.

Syed received his Bachelors in Business Administration from University of Dhaka (Bangladesh) in 2013, and his MS in Computer Science from United International University (Bangladesh) in 2015. Syed has served as a research assistant to Prof. Md. Kamrul Hassan, University of Dhaka, participating in studies “Network analysis of NGOs in Bangladesh” and “Network Analysis of the Mediation Driven Attachment (MDA) Model”.

Brennan Klein

Brennan received his BA in Cognitive Science and Psychology from Swarthmore College in 2014, focusing on the relationship between perception, action, and cognition. Currently, in his work with Professor Chris Riedl, he is researching human decision making, complex problem solving, and group behavior. This primarily involves running online experiments with human participants, as well as simulations of human behavior through agent-based modeling.

third year

Carolina Mattsson

Carolina is studying how network science and digital traces can be applied to study political science and, more specifically, international development. She comes from a background in both Physics and International Relations. Currently, she is working as a research assistant for Professor David Lazer on various projects.

first year

Stefan McCabe

Stefan received a BA in Government and International Politics and an MA in Computational Social Science from George Mason University. His prior research includes work on agent-based economics and optimizing agent-based models in high-performance computing environments. His research interests include political communication, the intersection of network science and agent-based modeling, and natural language processing.

first year

Ronald Robertson

Ronald is a 2016 Forbes Under 30 Scholar, a Research Associate at the American Institute for Behavioral Research and Technology (AIBRT), and volunteers as IT Director at 180 Degrees Consulting. After graduating cum laude from the University of California San Diego Ronald helped build AIBRT and published a variety of psychological research, including the discovery of the search engine manipulation effect. His primary research interests revolve around the subtle ways in which modern technologies and personal data can be leveraged to influence attitudes, beliefs, and behaviors.

first year

Rezvan Sherkati

Sarah Shugars

Sarah received her BA in Physics from Clark University, where she graduated Cum Laude in 2004. She received her MA in Integrated Marketing Communications from  Emerson College in 2009, and participated in Tisch College's Summer Institute of Civic Studies in 2013. An active member of the Somerville, MA community, Sarah serves as clerk of The Welcome Project board and on the board of the OPENAIR Circus. Sarah is interested in applying network science to questions of civil society and political deliberation.

second year

Matt Simonson

Matt's research interests center around using networks to study ethnic conflict and political violence.  His fieldwork has most recently taken him to Uganda, where he mapped friendship and economic networks among slum dwellers to measure self-segregation by religion and tribe.  Matt received a BA at Williams College in Math and International Studies and graduated cum laude in 2008. Prior to joining the PhD program, Matt worked with two peace-building organizations, Seeds of Peace and Search for Common Ground, and taught high school math at Milton Academy.  He is recipient of National Defense Science and Engineering Graduate Fellowship and was previously awarded an Innovation Fund grant to develop a course on Math, Politics, and Society, focusing on game theory and social choice.

first year

Leonardo Torres

Leo is interested in the intersection of Network Science, Complexity Science, and Neuroscience. By using different approaches from Computer Science, like graph mining and machine learning, he is trying to uncover the underlying principles governing the interplay between structure and function of dynamical networks. Leo has a B.S in Mathematics from a top-rated Peruvian Mathematics department, and is a self-taught programmer, having attended the Recurse Center, a programmers retreat in NYC, to focus on algorithm design and high-quality code writing standards.

Xindi Wang

Xindi received her Bachelor of Engineering from University of Electronic Science & Technology of China (UESTC) in 2015. Xindi served as a research assistant to Prof. Tao Zhou, UESTC, studying the Chengdu transportation network by analyzing real traffic data. Xindi participated in the MITACS Globalink program at Ryerson University, Canada, studying under Prof. Anthony Bonato and Dr. Deepak Bal.

first year

Chia-Hung Yang

Chia-Hung received his BA in Physics from National Tsing Hua University(NTHU) in Taiwan. His prior research with Prof. Kuo-An Wu, NTHU, studies pattern formation of interacting prey-predator systems.

Amar Dhand

As an Assistant Professor at BWH/HMS, Amar is a network scientist with expertise in examining the impact of social network structures on stroke recovery. In collaboration with Dr. Laszlo Barabasi and the Network Science Institute, Dr. Amar Dhand will work in the area of network medicine, including a project on social networks and stroke recovery in which he is examining the evolution of network structure after strokes, the association of networks with recovery outcomes, and underpinning mechanisms. He is also working with hospital networks derived from health administrative data to ask questions of the effect of networks on inpatient mortality, network motifs of acute and chronic diseases, and the dynamics of networks after policy changes. Overall, his goal is to understand patient networks and translate this understanding into network interventions to improve health outcomes.
