I am a Ph.D. Candidate at the Fletcher School and a Senior Ph.D. Research Fellow at the Center for Strategic Studies at Tufts University. My research focuses on civil-military relations, intrastate conflict, democratic governance, and international security with a regional interest in Russia, Ukraine, and Israel.

I rely on a quantitative and qualitative methodology. Being proficient in Russian, Ukrainian, Hebrew, and English allows me to collect data through fieldwork, archival research, and the analysis of original sources. My work was published by Perspectives on Terrorism, War on the Rocks, and the World Peace Foundation


I was selected as a 2019 - 2020 US Institute of Peace - Minerva Peace Scholar Fellow and World Politics and Statecraft Fellow at Smith Richardson Foundation. My research is also supported by the World Peace Foundation and Bradley Foundation.

Before coming to Fletcher, I studied Diplomacy, Conflict Resolution, and Counterterrorism at IDC Herzliya (Israel). I also worked as a professional educator in Kyiv, Ukraine, and Tel Aviv, Israel.


In my free time, I enjoy birdwatching, hiking, practicing yoga and Krav Maga.




Dissertation Project

Explaining Erosion of Civilian Control: A Policy-focused Theory

How do the government's policies affect the role of the military in politics? My dissertation offers a theory explaining under what conditions the government's policies about the use of force can weaken civilian control of the military. I develop a comprehensive analytical framework that allows capturing erosion of civilian control beyond coups. Methodologically, I combine process tracing with cross-case comparisons to test the explanatory power of the new theory in the context of the intrastate use of the armed forces. My research relies on extensive fieldwork in Russia, Ukraine, and Israel. The findings will offer useful insights into the role of the civilian side of civil-military relations in expanding the role of the military in politics.

Peer-reviewed Publication

(w/Assaf Moghadam and Ronit Berger)

Say Terrorist, Think Insurgent: Labeling and Analyzing Contemporary Terrorist Actors

Terrorist groups are commonly understood to be groups that carry out acts of terrorism, and their actions viewed as terrorist campaigns. This article offers empirical evidence in support of our argument that most major contemporary terrorist groups also employ other, non-terrorist, modes of warfare, notably guerrilla tactics. The main policy recommendation is for governments to separate the official labeling of these groups from the analysis of their origins, conduct, and threat potential.

Analytical Report

(with Sam Perlo-Freeman)

Corruption in the Russian Defense Sector

Today, Russia is the world’s fourth largest military spender and second largest arms exporter. Nevertheless, corruption still constitutes a significant problem facing the Russian arms industry. This report discusses publicly available information on corruption in the Russian defense sector, especially the arms industry, identifying key cases of corruption that have become visible in recent years.

Working Paper

Erosion of Civilian Control in Democracies: A Comprehensive Framework

Civilian control of the military is a fundamental attribute of democracy. However, existing empirical studies that treat civilian control as a dependent variable mostly focus on one form of erosion (e.g., coups, mutinies, defections) overlooking the others. The lack of a comprehensive analytical framework impedes scholarly efforts in the systematic analysis of civilian control, especially across regimes. This paper offers a new typology of erosion sensitive to the nuanced fluctuations in power balance between civilian governments and the military.


Topics in Russian National Security (Fall 2019)

Instructor of Record, Tufts University

What does the security landscape look like from the Kremlin’s window? This discussion-based undergraduate seminar covers 12 topics in Russia’s national security that help to answer this question. These include: how geography affects Russia’s security, relations with the West, Russia’s sphere of influence, the war in Ukraine, internal security threats, corruption, Russia’s security toolkit, “hybrid” warfare, information security, and nuclear strategy. The goal of this seminar is to familiarize participants with how officials in Moscow view threat environment, identify security priorities, and decide which means to employ for their achievement. The collection of class materials relies heavily on sources published after 2014. Original government documents and leadership statements translated into English provide a first-hand perspective on Russia’s security thinking.


Introduction to International Relations (Fall 2018)

Teaching Assistant, Prof. Jeffrey Taliaferro, Tufts University

At the core of my teaching approach is connecting the class knowledge to current events in international politics. For the discussion sections in International Relations, I encouraged students to analyze current news reports by using the theories discussed in class. In teaching evaluations, students noted that they found applying their knowledge to real life events useful and stimulating. 

I employ various discussion technics to engage students with different learning preferences.
