Urbanism & Neighborhoods

CPRC scholars in our Urbanism and Neighborhoods primary research area group examine neighborhood change, including impacts on population health, producing original research as well as datasets that are a vital a resource for CPRC affiliates and others doing NIH-supported work on spatial approaches to health. Longitudinal analysis of health and well-being is a focus of several affiliates, who collaborate on two panel studies of representative samples of NYC residents with a focus on poverty, disadvantage, health, and well-being. Creating new data on neighborhood characteristics is another focus; affiliates created a web application – the “Computer Aided Neighborhood Visual Assessment System” (CANVAS) which implements neighborhood audit studies via Google Street View. In addition, affiliates have created two datasets, available to collaborators at CPRC, which provide fine-grained details on how urban form has changed over the past 30+ years.

  • Vegard Skirbekk is a Norwegian population economist and social scientist specializing in demographic analysis and cohort studies. He is currently senior researcher at Norwegian Institute of Public Health  and also Professor of Population and Family Health at Columbia Aging Center at Columbia University.

    He is working at the Columbia Aging Center at Columbia University.  He was awarded the ERC “Starting Grant” which allowed him to set up his own research team. As project leader of the Age and Cohort Change Project, he has worked on extending the understanding of global variation in skills and values along age, period and cohort-lines. His group has already produced the first worldwide estimates of faith and beliefs (covering 199 countries) in a partnership with the Pew Research Center.

    Skirbekk has focused on studying health, productivity, and associated determinants from a multidisciplinary perspective with an emphasis on the role of changing labor market demands, technological and cultural changes as well as variation in the attitudes, beliefs, and competences of new cohorts.  From considering productivity as an output variable (e.g., measured as value-added, salary levels), a key contribution of his research has been to highlight the integral role of productivity determinants (such as skills, health, and abilities). This research has helped change the focus of age-variation in productivity from something fixed to an entity that is to a greater extent modifiable. While earlier work typically used chronological age distributions to describe trends over time and variation between countries in how "old" they are, Skirbekk's research as shown that how old a population effectively is should be based on objective measures such as cognitive and physical functioning levels rather than chronological age. Accordingly, countries can be functionally younger even if they are demographically old based on objective measures rather than chronological age structures. Skirbekk's research has been published in a variety of academic journals (including PNAS, Lancet, Science).  and has been presented popular science outlets New Scientist). His work has been discussed in media around the world, including The New York Times, the TV news channel CNN, and The Economist

  • Seth J. Prins, PhD MPH, is Assistant Professor of Epidemiology and Sociomedical Sciences at Columbia University's Mailman School of Public Health. He completed his doctoral training in the Department of Epidemiology, and his postdoctoral training in the Department of Sociomedical Sciences and the School of Social Work, at Columbia University. Dr. Prins's two programs of research concern the collateral consequences of mass incarceration for public health, and the effects of the social division and structure of labor on mental illness. Two questions have motivated his work to date: First, what are the theoretical and methodological assumptions underlying the growing use of psychiatric categories, such as antisocial personality, to explain and assess the risk of exposure to the criminal justice system, particularly in the context of mass incarceration? Second, what can we learn about the distribution and determinants of mental illness by examining social class as a dynamic relational process, rather than an individual attribute? Dr. Prins is also working on a project to study the role of adolescent substance use as determinant and consequence of the school-to- prison pipeline, disentangling individual risk, social determinants, and group disparities. Dr. Prins explores these questions at the intersections of epidemiology, sociology, and criminology, combining theory-driven analysis with advanced quantitative methods. He is a social and psychiatric epidemiologist interested in pushing the boundaries of the discipline to encompass rich social theory.

  • Mario L. Small, Ph.D., is a Quetelet Professor of Social Science in the Department of Sociology at Columbia University. He has made numerous contributions to research on urban neighborhoods, personal networks, qualitative and mixed methods, and many other topics.  He has shown that poor neighborhoods in commonly-studied cities such as Chicago are not representative of ghettos everywhere, that how people conceive of their neighborhood shapes how its conditions affect them, and that local organizations in poor neighborhoods often broker connections to both people and organizations.  Small has demonstrated that people's social capital—including how many people they know and how much they trust others—depends on the organizations in which they are embedded.  His work on methods has shown that many practices used to make qualitative research more scientific are ineffective.  Small's most recent book examines why people are consistently willing to confide their deepest worries to people they are not close to.

  • Past Research: Professor Edlund’s research focuses on the economics of gender and family, interests that have also led her to evolutionary biology and life-history analysis. Edlund’s past research has analyzed the impact of marriage and partner market conditions on sex allocation, with a particular focus on the status of females. She has studied son preference and sex selective abortion, dowry determination, why cities in the industrialized world are more female, and sex allocation at the individual level. She has also been interested in the importance of female inheritance for the gender wealth distribution. Another strand of her research has explored the legal framework governing formal marriages across cultures, an interest that has led to studies of markets for sex and children, consent regimes (parental or individual consent), and the alignment of political preferences along gender lines in the wake of the sexual revolution ushered in by the Pill.

    Present Research: Edlund’s current research focuses on maternal conditions and child outcomes. One paper looks at male vulnerability in early life. While it is well known that males suffer higher mortality than females at all ages, particularly up until age one, it is less well known that males suffer more from poor maternal conditions; Edlund and colleagues document this phenomenon, studying perinatal and infant mortality in the United States. A second paper examines maternal malnutrition and long-term (adult) outcomes of offspring using the Chinese Great Leap Forward famine as a natural experiment. Maternal malnutrition remains a problem in many developing countries where pregnant and lactating women are high-risk groups for nutritional inadequacy. A third paper looks at cognitive effects of fetal low-level ionizing irradiation. Sweden received substantial radioactive fallout following the Chernobyl nuclear accident that took place in Ukraine in 1986. We find that Swedish children in utero at the time performed worse in their final year of compulsory school (at age 16) than their peers who were not exposed, and the damage was more severe for children born in areas that received more fallout. Doses to the Swedish population were such that the results are relevant for policy formulation relating to, e.g., radon exposure, medical procedures, radiation workers, and recommendations in the case of a terrorist attack involving a so-called dirty bomb.

    Future Research: Future work will investigate whether there were earlier health manifestations presaging the observed effects for Swedish children (perinatal outcomes, in-patient records), as well as track this cohort as it ages and as additional outcomes (fertility, mortality, labor market) become available. We will also explore the role of parental socioeconomic status in buffering the health and labor market impact of negative shocks to cognitive ability. Other work will investigate the effects of paternal absence on teenage girls, and the relationship between height and mortality.

  • Kartik Chandran is a global leader in sustainable wastewater treatment and engineered resource recovery.  Chandran’s work is enabled through understanding and harnessing the biochemical potential and metabolism of microbial communities and developing appropriate technologies towards addressing global environmental and societal needs.  

    His fundamental work has focused on elucidating the molecular mechanisms and pathways of the microbial nitrogen cycle and its links to the global carbon, water and energy cycles. His applied work ranges from large-scale centralized wastewater treatment systems to community scale decentralized resource recovery systems and technologies across the globe. 

    The key insight of Chandran’s research and applications thereof is that certain combinations of mixed microbial communities, similar to those that occur naturally, can be used to mitigate the harmful environmental impacts of wastewater and to extract useful products. This approach also involves reduced chemical and energy inputs relative to traditional treatments and has the added benefit of preventing algal blooms downstream by maximizing nitrogen removal. More recently, using ammonia-oxidizing bacteria, Chandran has enabled the transformation of bio-generated methane gas into methanol, a chemical that is both easily transported and widely useful in industry (including in the wastewater industry).

    Chandran imaginatively tailors his solutions to be locally appropriate. In rural Ghana, in conjunction with his Engineers without Borders students, he has re-engineered source-separation toilets to both provide sanitation and recover nutrients for use in agriculture. In Kumasi, Ghana, he has tested the large-scale conversion of sludge into biofuel while also providing new training opportunities for local engineers and managers. Through his groundbreaking research and its practical applications, Chandran is demonstrating the hidden value of wastewater, conserving vital resources, and protecting public health.

    Chandran received his B.E. in Chemical Engineering from the Indian Institute of Technology, Roorkee (formerly the University of Roorkee) in 1995 and his Ph.D. in Environmental Engineering from the University of Connecticut in 1999.  He received a MacArthur Foundation Fellowship in 2015 and was named a Fellow of the Water Environment Federation in 2013.

  • Dr. Ford is a sociologist who conducts research at the junction of social science and public health, with particular emphasis on how expectations and inequalities around gender and sexuality shape sexual violence, health, and pleasure. Dr. Ford’s work brings a fresh perspective to sexual and reproductive health by deploying insights from the sociology of culture and studies of gender inequality. What facilitates a healthy sexual interaction? Why do people have unwanted sex and when does an experience shift over into sexual assault? These questions remain topics of ongoing public debate. While much research has focused on disentangling the individual-level factors (e.g. drinking, past victimization), and sometimes even more structural factors (rape myths; campus environments), less is known about the social production of sexual outcomes at the interactional-level. What Dr. Ford brings to the study of sexual health is rigorous engagement with the importance of social interactions with particular attention to how gender inequality is reproduced in sexul interactions. Dr. Ford received her Master’s Degree in Public Health from the London School of Hygiene and Tropical Medicine and her Doctorate in Sociology from New York University. In her current postdoctoral position at Columbia University’s Department of Sociomedical Sciences, Dr. Ford works under Dr. Mark Hatzenbuehler (on the CPRC Steering Committee) to implement an NIH R01 grant researching the effect of structural stigma on the sexual health of gay and bisexual men in the United States.

  • Ami Zota is a population health scientist with expertise in environmental health, environmental justice, and maternal and reproductive health. Her research focuses on understanding social and structural determinants of environmental exposures and their consequent impacts to women's health outcomes across the life course. Her long-term goal is to help secure environmental justice and health equity among systematically marginalized populations by advancing scientific inquiry, training next generation leaders, increasing public engagement with science, and supporting community-led solutions for structural change. Dr. Zota was among the first to frame the disproportionate burden of toxic chemical exposures from beauty and personal care products among women of color as an environmental justice concern. She co-developed an intersectional framework called "the environmental injustice of beauty", which links systems of power and oppression, such as racism, sexism, and classism, to Eurocentric beauty norms, racialized beauty practices, and adverse environmental health outcomes. She currently works with community-based research collaboratives in New York City and Los Angeles to reduce risks from unregulated chemicals in consumer products among Black, Latinx, and Asian women and femme-identifying individuals. Another key area of Dr. Zota's research is understanding how state and federal policies can impact environmental health risks. She is a PI of a study whose goal is to examine whether federal housing assistance programs reduce exposures to lead, second-hand smoke, and other environmental chemicals among low-income households. Lastly, Dr. Zota also has expertise in evaluating social, environmental, and molecular determinants of women's health across the life course, including pregnancy outcomes, gynecologic outcomes, cardiometabolic outcomes, and cancer. For example, Dr. Zota is PI of the FORGE study, which leverages the intersectionality exposome to identify modifiable drivers of racial inequities in uterine fibroids. Her research is funded by the National Institutes of Health, US Department of Housing and Urban Development, California Breast Cancer Research Program, and private foundations. Dr. Zota is the founding director of the Agents of Change in Environmental Justice program which seeks to foster more diverse, equitable and inclusive leaders in environmental and climate justice. Agents of Change in Environmental Justice trains early career scientists from systematically marginalized backgrounds in science communication, storytelling, community engagement, and policy translation.

  • Dr. Abigail (Abba) Greenleaf is a public health demographer whose research focuses on collecting data in low- and middle-income countries where using cell phones to survey populations is an increasingly viable methodology. In the United States, phone-based surveys have been common since the 1980s. In areas such as Africa, until recently there was not sufficient cell phone ownership to create valid phone-based health estimates, and researchers like Dr. Greenleaf have been assessing the reliability of this increasingly popular approach to data collection.

    Dr. Greenleaf currently works with ICAP's Population-Based HIV Impact Assessment (PHIA) project. Carried out under the leadership of national ministries of health, PHIA data benchmark a country's progress towards controlling the HIV epidemic. Dr. Greenleaf enjoys this rigorous research because it is efficient, cost-effective and produces high-quality data that can inform targeted policies and programs. As COVID-19 epidemic restraints slowed progress with the PHIA project in several countries, Dr. Greenleaf became part of a team that quickly catalyzed PHIA data and participants in Lesotho to begin a phone-based surveillance system for coronavirus-like symptoms. This real-time data creates weekly estimates infection levels for the national ministry of health.

    After a public health class in college introduced her to the field, Dr. Greenleaf joined the Peace Corps to understand public health in a global context, and she spent two years in Cameroon. She then pursued an MPH at Columbia and after she worked for Centers for Disease Control as an Allan Rosenfield Global Health Fellow in Ethiopia and Cameroon. She earned her PhD in the Population, Family and Reproductive Health Department at Johns Hopkins Bloomberg School of Public Health before coming back to Columbia. In addition to her research, Dr. Greenleaf spends a portion of her time teaching.
