Welcome to my website.

I am a political scientist working on political parties, social policy and democratic decline, primarily in the Middle East and North Africa. I received my PhD in political science from Harvard University Government Department (July 2021). During the 2021-2022 academic year, I am a Post-Doctoral Fellow at Stanford University’s Center on Democracy, Development and the Rule of Law (CDDRL). Beginning from August 2022, I will be an Assistant Professor of Political Science at Bryn Mawr College.

My dissertation/book project explores the reasons behind the weak electoral appeal of secular parties in the Middle East after the popular uprisings of 2011-2013 and why they could not form a robust electoral alternative to Islamist parties. I undertake a close case analysis of two large secular parties in the region, Cumhuriyet Halk Partisi (Republican People’s Party) in Turkey and Nidaa Tounes (Call of Tunisia), and exploit the subnational variation to test various hypotheses. I find that, unlike many conventional expectations, valence deficit and inability of secular parties to signal good governance credentials are among the main causes of secular disadvantage. The valence deficit stems from negative political selection and problems in organizational cohesion, i.e. inability of social networks within the party organization to cooperate effectively.

The data for this project comes from interviews with party elites and candidates, novel and large-scale candidate surveys, and contemporaneous household surveys in both countries. Data collection was supported by Democracy International, Belfer Center for Science and International Affairs, Weatherhead Center for International Affairs, Institute for Quantitative Social Science and Center for Middle Eastern Studies at Harvard University.

My other current projects explore how parties and charities engage in and affect the quality of primary healthcare in Lebanon, the role of international organizations in social policies for refugees, and citizens’ responses to autocrats’ assaults on democratic institutions.

How Voters Respond to Presidential Assaults on Checks and Balances: Evidence from a Survey Experiment in Turkey
(with Alper Yagci and Daniel Ziblatt)
Comparative Political Studies, 2022

Why do voters support executive aggrandizement? One possible answer is that they do so because they think this will ease their preferred leader’s hand in putting their partisan vision into action, provided that the leader will continue winning elections. We study this phenomenon through a survey experiment in Turkey, by manipulating voters’ perceptions about the potential results of the first presidential election after a constitutional referendum of executive aggrandizement. We find that voters from both sides display what we call “elastic support” for executive aggrandizement; that is, they change previously revealed constitutional preferences in response to varying winning chances. This elasticity increases not only when citizens feel greater social distance to perceived political “others” (i.e., affective polarization) but also when voters are concerned about economic management in a potential post-incumbent era. Our findings contribute to the literature on how polarization and economic anxiety contribute to executive aggrandizement and democratic backsliding.

Book Project


This project brings a new perspective to a long-standing question in political science and Middle East studies: Why have secular parties remained weak in the aftermath of uprisings, despite their historical and organizational advantages? Predominant political science literature on the Middle East focuses almost exclusively on Islamist parties, and the few explanations derived from extant literature attribute the decline of secular parties to weak ideological support for secularism among the Middle Eastern public, the absence of institutional venues for secular actors to interact with the larger public, or elitism of leaders and activists in secular parties. Yet, by and large, these accounts have not been tested rigorously. Moreover, they do not explain how secular parties remain strong at some historical times and in some subnational areas but not in others.

I argue that the weakness of secular parties in the Middle East is largely the result of a “valence” problem, rather than an ideological mismatch or absence of mobilizing structures. Secular parties suffer from electoral underperformance when and where they lack trust of voters in their capability to solve problems and deliver socio-economic development. The valence deficit of secular parties has two main sources: First, these parties are characterized by intra-party competition and lack of organizational cohesion, i.e. a deficit in the capacity and willingness of party activists and candidates to collaborate and remain unified. Secondly, they cannot recruit and select competent candidates, who could have built good governance credentials for the party. Voters who witness in-party fighting and a cadre of politicians who seem incapable of solving socio-economic problems turn to alternative parties, mostly Islamists.

I demonstrate the effect of organizational cohesion on electoral strength with subnational analyses for two important secular parties in the region, Nidaa Tounes and Republican People’s Party, in the most recent local elections in Tunisia and Turkey. In both countries, I conducted extensive interviews with central and local political elite, original and representative candidate surveys, and contemporaneous household surveys. Borrowing from organizational psychology and building on earlier studies of organizational strength in political science, I measured the organizational cohesion of parties at the municipal level and show that it is significantly associated with election results. I substantiate my argument with data from post-election interviews and original household survey data on the potential causal linkages between these variables.

This graph shows the relationship between organizational cohesion and secular-Islamist vote difference in the 2018 local elections in Tunisia. Each dot represents a city in which I was able to measure the organizational cohesion of both secular party’s and Islamist party’s local branch just before the elections. The fitted line comes from an OLS regression with various controls. In the cities in the red font, I conducted post-election interviews to better understand how and in which circumstances organizational cohesion was likely to lead to electoral strength.

A second source of valence deficit of the old secular-modernist parties in the region is candidate quality: Secular parties cannot attract the most competent segments of their core constituency, urban professional middle classes, neither as party activists nor as candidates. To substantiate this argument, I provide a detailed a descriptive account of political selection pipeline of secular parties, bringing together household surveys, candidate surveys and candidate selection experiments with party officials. I then compare them to the political selection pipeline of Islamist parties, and demonstrate that secular parties end up with less qualified, less competent and less cooperation-spirited candidates.

This graph shows the share of people with higher education (a proxy for competence) among the Islamist and secular voter bases, eligible aspirants and candidates of the two main parties in Tunisia’s 2018 local elections. The data comes from an original candidate survey and a contemporaneous household survey.

Considering the characteristics of the voter base and core constituency of secular-modernist parties, the difficulties secular parties face to construct cohesive organizations and find competent candidates are puzzling. To explain this, I turn to macro-sociological processes: First, more competent segments of the core constituency of secular-modernist parties, which are derived from the urban professional middle classes, have been in a decades-long process of disengagement from party politics, in part because globalizing economic reforms have changed their life strategies and increased their exit options. Members of this social stratum have the professional skills and resources that could have built both organizational cohesion and governance credentials for secular political parties. Instead, they opted to seize opportunities within the private sector, employment in multi-national corporations, and emigration. Second, as state-builders, secular parties have historically nurtured distinct patronage distribution networks, which are in constant competition with each other on the basis of hometown, sect, or occasionally personal animosity between leaders. While these patronage networks ensure the survival of the party by incorporating an extensive network of local branches into the center, they give rise to constant intra-party struggles and push members of the urban professional middle classes further away from involvement. Thus, secular parties cannot build functional and reliable organizations that would have brought them electoral advantage.

social services in the context of ethnic and organizational diversity

How do ordinary people navigate social welfare regimes characterized by diversity of (non-state) provider organizations? Are non-state organizations more likely to discriminate in favor of their co-ethnics? Which type of organizations (religious charities, or secular NGOs) are more likely to provide higher quality services, and why? Which organizations provide equal or superior quality for most vulnerable groups, such as refugees?

We explore these questions with original data from Lebanese primary health care network. In collaboration with 13 local research assistants, we collected data from ~70 centers, 200 doctors and 1200 patients, with patient exit interviews, surveys and tests with doctors and chief medical officers, and direct observations of doctor-patient interactions.

Political organizations in the Middle East and North Africa

How are political parties built and organized in the MENA region? Who becomes a politician and why? How do the party elites and novice politicians react to institutional rules, citizens’ requests and social movements around them?

The extensive dataset we collected from the local election candidates in Tunisia’s first democratic local elections in 2018 allows us to answer a number of theoretically interesting questions.
