Spring 2023 Colloquium Series

Informal talks given by faculty and guests, both in person and via Zoom
Noon-1 p.m. on select Thursdays

Thursday, May 4

Tara Dhakal, associate professor of electrical and computer engineering and director of the Center for Autonomous Solar Power (CASP) at Binghamton University, will speak on "Recent Progress in Thin Film Perovskite Solar Cells" at noon Thursday, May 4, in AA-340 and via Zoom at

Perovskites are being extensively explored for both solar cells and lighting applications. To say that perovskites are wonder materials for the optoelectronic industry is an understatement. Generally, perovskites have a three-dimensional ABX3 structure (A: organic or inorganic cation, B: metal cation, X: halogen) in which self-organized two-dimensional (2D) planes of organic layers (AX) are sandwiched between 2D planes of inorganic halides (BX2). Organic-metal halide perovskites have shown remarkable improvement in recent years, with efficiencies increasing from 3.8% in 2009 to 25% in 2023, which is close to long-commercialized silicon solar cells. This presentation will cover a general overview of various solar cell technologies and a discussion on the recent progress in perovskite thin film solar cells. In addition, our group’s work on the effect of buffer layers on both reliability and performance of the perovskite solar cells will be presented.

Thursday, Nov. 17

Pam Mischen, associate professor of public administration at Binghamton University, will speak on "Community Types through the Lens of Sustainability: Understanding the Past and Present to Impact the Future" at noon Thursday, Nov. 17, in AA-340 (lunch will be provided) and via Zoom at 

Everyone wants to live in an environmentally healthy, economically vibrant, and socially equitable community—but how many Americans do? Are there any communities in the US that we can call sustainable? This study examines 886 metropolitan and micropolitan statistical areas in the continental US and clusters them into 11 community types based on 17 sustainability outcomes. Drawing on the literature on sustainability transitions, we now seek to explain how these clusters came to be by identifying unique combinations of historical variables that predict inclusion into each cluster. By understanding the physical, demographic, cultural, policy, and economic factors that have resulted in these community clusters, we can better guide communities to a more sustainable future.

Thursday, Nov. 3

Kyle Gowen, PhD student in anthropology at Binghamton University, will speak on "Anthropological observations on the successes and challenges of the Broome County Food Council (BCFC)" at noon Thursday, Nov. 3, in AA-340 (lunch will be provided) and via Zoom at 

Revitalized by the devastating effects of the COVID-19 pandemic, the Broome County Food Council (BCFC) has brought together organizations and diverse stakeholders to collaborate on increasing food security throughout the region. Over the past several months, as part of a project for the Food Justice Working Group of the Sustainable Communities TAE, I have attended and participated in discussions on how the BCFC can better serve those who are food insecure. My presentation synthesizes these observations into three themes focused on the strengths and challenges of the BCFC. I conclude with insights into how the BCFC will continue to grow and change as it begins building a food plan for Broome County.

Thursday, Sept. 22

Neha Patankar, assistant professor of systems science and industrial engineering at Binghamton University, will speak on "Exploring uncertainties and tradeoffs on the way to net-zero energy systems" at noon Thursday, Sept. 22, in in AA-340 and via Zoom at 

Transitioning to zero-carbon energy infrastructure entails collaborative decision-making between utilities, policymakers, and stakeholders with conflicting objectives. In the real world, these conflicting objectives need to be resolved locally at a much higher spatial resolution than what mathematical models can handle. In this talk, I develop a framework that can make it easier for communities to create clean-energy plans that incorporate their community values and identify preferred least-regret spatial patterns of clean energy infrastructure deployment. I will present two case studies that use linear programming based spatially, temporally, and operationally resolved power system model to evaluate resource tradeoffs in the United States. In the first case study, I will demonstrate the modeling framework's utility for assessing the impact of the Inflation Reduction Act (IRA). In the second case study, I will examine land-use portfolios based on several non-cost related metrics representing technological, social, and ecological objectives. Lastly, I will discuss my future research plans to develop a generalizable tool. It will allow decision-makers to explore technology and resource tradeoffs in real-time to facilitate collaborative decision-making.

Thursday, Sept. 8

Len Fisher, senior research fellow at the School of Physics at the University of Bristol, UK, will speak on "Communicating Complexity: The World’s Most Important Problem" at noon Thursday, Sept. 8, in AA-340 and via Zoom at 

The multiple threats that the world now faces are complex in themselves, and are also interlinked in an overarching complex network. For effective governance, the consequences of these inter-linkages need to be understood and acted upon by the world’s decision makers [1]. Unfortunately, the record of those decision makers in this regard is not hopeful. In this talk I will examine avenues for communicating the importance of complexity to decision-makers, and ask how we can better promote it as a fundamental platform for the governance of global catastrophic risks. [1] Fisher, L., & Sandberg, A. (2022). A safe governance space for humanity: Necessary conditions for the governance of global catastrophic risks. Global Policy.

Australian scientist Fisher obtained his PhD in physics at the University of New South Wales, Australia. He is internationally renowned for his unique research on everyday real-world topics involving physics, chemistry and complex systems, and for his highly accessible and engaging scientific communication to the public. His recent research covers social and global issues, including global policy and adaptive governance for human sustainability. He is the recipient of the Ig Nobel Prize in Physics (1999) and the Medal of the Order of Australia (2019) for his contribution to science.

Spring 2022 Colloquium Series

Noon-1 p.m. on select Thursdays

Thursday, April 28

Binghamton University's Christopher Zosh, Jeremy Blackburn, Barrett Brenton, Robert Dinapoli, Carl Lipo, Pamela Mischen, Hiroki Sayama and Andreas Pape as well as William Rand from NC State and Brooke Foucault Welles from Northeastern University will speak on "An Agent-Based Model of the Collective Action Dynamics of Goal-Driven Groups" at noon, Thursday, April 28, in AA-340. The talk, which is open to everyone, will also be conducted via Zoom

We present an agent-based model of collective action dynamics in which individuals voluntarily associate with goal-driven groups to induce social change. The model assumes a multidimensional outcome space, where each dimension represents a different factor, such as policies on tax rate or education funding, or non-policy outcomes like maintenance of a community’s outdoor environment. In the outcome space is the world state, i.e. the currently enacted policy or status of non-policy outcomes. Individuals and groups have goal preferences in the outcome space. Individuals decide which groups to join based on groups’ goal preferences, and groups organize events to influence the world state. The role of on- versus off-line activity is reflected in the costs and effectiveness of individual effort. The model examines the membership of the groups, the actions the groups’ members undertake, and the movement of the world state (i.e., how and which goals are achieved). One key parameter of this model is the democratic responsiveness of groups, i.e. how quickly the goals of the group comes to match the goals of the membership. We find that democratic responsiveness of groups is only sometimes helpful in achieving positive social outcomes: in particular, democratic responsiveness can harm social outcomes if some groups can be captured early by a cabal of individuals. 

We discuss future extensions, including bringing this to social media data.
