Future Leaders in CEE: Towards Network-driven Human-centered Infrastructure Resilience & Sustainability
Speaker: Arif Mohaimin Sadri, PhD, EIT, Assistant Professor, Moss School of Construction, Infrastructure & Sustainability Florida International University Dr. Arif Sadri is an Assistant Professor in the Moss School of Construction, Infrastructure & Sustainability (MSCIS) at the Florida International University (FIU). Previously he was a Visiting Assistant Professor in the Department of Civil & Environmental Engineering at the Rose-Hulman Institute of Technology and an Adjunct Professor in the Civil Engineering Dept. at the Valparaiso University. Dr. Sadri received his doctoral training from the Lyles School of Civil Engineering at Purdue University with a solid background in Civil Engineering (Transportation), Network Science, and Social Science. Dr. Sadri specializes in resilience engineering, evacuation modeling, shared mobility, social influence modeling, machine learning, agent-based modeling, and network modeling. Dr. Sadri's research focuses on the critical interdependence between social and infrastructure networks and integrates human proactive decision-making components into the civil infrastructure management challenges. Dr. Sadri develops human-centered and network-driven techniques that complement to the science of infrastructure resilience and sustainability. Dr. Sadri's research is currently funded by National Science Foundation (NSF), United States Department of Transportation (USDOT), Florida Department of Transportation (FDOT) and United States Agency for International Development (USAID). Dr. Sadri’s previous research was funded by the National Science Foundation (NSF), Indiana Department of Transportation (INDOT), Indiana Local Technical Assistance Program (LTAP) and Andrew W. Mellon Foundation. The complex topology of real networks allows network agents to change their functional behavior. Conceptual and methodological developments in network analysis have furthered our understanding of the effects of interpersonal environment on normative social influence and social engagement. Social influence occurs when network agents change behavior being influenced by others in the social network and this takes place in a multitude of varying disciplines. The overarching goal of this talk is to provide a holistic understanding and present novel techniques to explore how individuals are socially influenced, both on-line and off-line, while making shared- trips, interacting in respective communities, and communicating risk during extreme weather. The notion of influence is captured by quantifying the network effects on such decision-making and characterizing how information is exchanged between network agents. The methodologies and findings provide key insights into the implementation of targeted strategies for various user groups in day-to-day as well as crisis events based on their social network characteristics, properties, activities, and interactions. As part of fostering system sustainability and resilience to external shocks, the purpose of identifying influential network agents in co-dependent socio-physical systems will also be discussed. Based on real stories, the talk will conclude how diversity and inclusion activities can be leveraged through social networks and peer influence.

Future Leaders in CEE: Mobility and epidemics in urban typologies
Speaker: Dr. Jimi B. Oke, Assistant Professor, Department of Civil and Environmental Engineering, University of Massachusetts Amherst As our cities and communities continue to grow in complexity, smart solutions are required to promote accessibility, resilience and sustainability, particularly in mobility and energy networks. In this talk, I describe a novel study of over 300 cities which employs unsupervised learning to determine the driving factors of mobility and sustainability in today’s urban areas. From several of these typologies, we develop prototype cities to analyse how future automated mobility-on-demand outcomes vary by city type. The dynamics of an epidemic can also be investigated across typologies. I discuss an agent- and activity-based fully-mechanistic epidemiological model which simulates the propagation of COVID-19 in US typologies. In this ongoing study, we analyse the activity-specific scaling properties of the highly spatio-temporally resolved contact networks of city populations. Our findings provide insights for understanding urban epidemic propagation and effective mitigation strategies in cities. Finally, I will discuss my academic journey and share insights in navigating the tenure-track faculty application. Dr. Jimi B. Oke is an Assistant Professor in the Department of Civil and Environmental Engineering at University of Massachusetts Amherst, where he directs the Networks for Accessibility, Sustainability and Resilience Laboratory. From 2016 to 2019, he was a Postdoctoral Associate at the Intelligent Transportation Systems Lab working on the MIT Energy Initiative’s Future Mobility Study. Dr. Oke received his MSE and PhD in Civil Engineering from the Johns Hopkins University, where he studied from 2012 to 2016. Prior to graduate school, Dr. Oke taught mathematics at The Pennington School after graduating from Williams College with majors in Physics and Music in 2010. His current research interests lie in advancing big data, machine learning and network science for energy-efficient, smart and resilient communities.

Future Leaders in CEE: On the Subject of Needs: Indebted Gestures and Other Acts of Inclusion
Speaker: Misty De Berry, Postdoctoral Fellow, Department of Literature; & Program in Women’s and Gender Studies Weaving together her experiences as an artist and scholar in the academy—where she literally grew up on her mother’s lap, Dr. De Berry explores the paradox of diversity. Although acts of diversity are worth celebrating, she asserts, we ought to return our attention continually to what such acts may also obscure. In the second part of the conversation, through gentle movement exercises and guided writing prompts, Dr. De Berry shares insights from her current project which takes up the relationship between structures of debt and the use of everyday aesthetics in the lives of Black women. She argues that institutional apparatuses like diversity or debt are embodied everyday performances. Taken by how such routine behavior can harm the lives of Black women, she asks how might we engage everyday behavior—from individual breath, movement, and perception, to collective care and the sharing of space—in order to re-imagine alternative modes of collectivity, inclusion, and social redress?

Future Leaders in CEE: From subsonic to supersonic: a site-specific study of single microparticle impact bonding
Speaker: Alade Ahmed Tiamiyu, MSc, PhD, EIT, Postdoctoral Research Fellow, DMSE, MIT From a humble background, the journey from the city of Lagos, Nigeria to Canada, and then, USA, will be discussed. I will highlight the unique challenges faced in the process leading to my current position and how I overcome them. The talk will be capped up by addressing Diversity and Inclusion from a small-scale family-model point of view. Cold spray is a fast-growing solid-state coating process with a high deposition rate that has been attracting industrial interest in the last decade. It involves the acceleration of solid powder particles at supersonic speed to impact and adhere to a substrate or previously deposited particles, forming coats. This unique technique is used to mitigate corrosion by depositing more noble materials of superior corrosion resistance on metallic substrates. It can also be used for in situ repairs of cracks, restoration/remanufacturing of unserviceable engineering/aeronautical components or corroded parts that are in service; making them reusable and in turn, save the cost of buying new products. For bonding to occur during cold spray, the impact velocity of the particle, must reach and exceed a critical velocity, and an intimate metal-metal clean contact must be achieved between the metal lattices. To expand the wide-spread application of cold spray to unconventional areas, the underlying mechanism of metal-metal bonding must be unearthed. Till date, the mechanism of bonding is under debate due to the difficulty in experimental observation of microparticle impacts that only span nanoseconds. In this talk, the major advances made in unravelling events that lead to bonding by studying single particle impacts from subsonic to supersonic regimes will be highlighted. Microstructural evolution at the particle-substrate interface will also be discussed.

Future Leaders in CEE: Transit User Mode Choice Behavior in Response to Rapid Transit Service Disruption
The Department of Civil and Environmental (CEE) Engineering at MIT has initiated a monthly seminar series to foster diversity and inclusion. Speakers from diverse backgrounds who are highly successful in their careers will give a talk about their journey to achieve success and their research. The goal of this initiative is to address the relative lack of representation of certain minority groups and to present examples of those who were able to overcome unique challenges. The format is that each speaker will present a two-part seminar - one part of the seminar will be an overview of their research, and another part of the seminar will be how they navigated through various challenges associated with diversity, equity, and inclusion in their careers. Speaker: Teddy Lin, MASc, EIT Transportation Planner at IBI Group Disruption of transit service is a common occurrence in many cities around the world, and these incidents may have serious impacts on the transit user’s journey. The purpose of this study is to investigate transit user commuting mode choice in response to rapid transit service disruption in the City of Toronto. A joint Revealed Preference and Stated Preference survey is designed to gather information on the respondent’s actual response to the most recent service disruption and also responses under a set of hypothetical service disruption scenarios. A transit trip planner tool is developed to generate alternative transit options to avoid the disrupted segment. Econometric models are presented, including a joint RP-SP model, showing that the following factors, in addition to travel time and cost, are significant at 95% confidence: frequency of subway trip, trip purpose, subway delay, shuttle bus delay, weather, age, and income. Policy implications are also discussed. Diversity, equity, and inclusion are important to leverage the full range of talent and skills and to realize the full potential of collective research advancement and education. Canada is a welcoming place that fully embraces diversity, equity, and inclusion. In this talk, the speaker will discuss how he has overcome challenges throughout his journey and how diversity, equity, and inclusion has shaped his life.
