Overview
I research the political origins of military power. Building a powerful military is often thought of as an optimization problem: given finite resources, states invest in the tools that maximize their chance of winning and preventing war. But states regularly make seemingly suboptimal spending decisions ill-suited to their security needs. For example, the United States omitted minesweepers from its 600 ship navy in the 1980’s despite their low cost and historical utility, and Albania in the mid-2000’s produced a fleet of coastal patrol vessels that can travel the 1,500 miles to Portugal despite it having a coastline of just over 100 miles. Why do states build militaries that are seemingly suboptimal given the threats a state faces? These decisions are crucial for understanding states’ interaction, both in war and peace. I argue that these choices are not a function of miscalculation or domestic log rolling. Rather, they follow from a strategic logic of specialization with trusted partners.
My research on military capabilities concerns two themes. First,what capabilities do states arm themselves with and why? Second, what consequences does the distribution of military capabilities have for states’ conduct in international affairs? While heterogeneity in states’ force structures is generally recognized, scholars still think about defense capabilities using aggregate measures like military spending because of limited data availability. Scholars also find it analytically convenient to treat military power as fungible. While political science has only recently started to identify and theorize differences in how states arm themselves, practitioners agonize over military allocation decisions during endless debates about how well particular capabilities meet their national security needs. States without sizable naval fleets are limited in their ability to project power while those with competent land forces are better equipped to seize and hold territory.

Use Their Force: Interstate Security Alignments and the Distribution of Military Capabilities
Why do capable states sometimes possess seemingly inefficient militaries that leave them vulnerable to security threats? Practitioners have long maintained that a full spectrum combined-arms military is the best defense in an unpredictable and anarchic international environment. Yet capable states often either forgo some vital defense capabilities, like the US omitting minesweepers from its planned 600 ship navy in the 1980s, or overproduce some defense capabilities, like Albania developing coastal patrol vessels with a range of 1,750 miles despite having a coastline that is roughly one tenth that size. Are states with seemingly inefficient militaries simply making mistakes? I argue that vulnerable force structures are not just the result of poor planning or resource constraints; rather, these observed “inefficiencies” are often a strategically motivated decision to specialize one’s force structure. While there are certainly advantages to a diversified military portfolio, states can engage in strategically motivated functional differentiation by specializing their militaries when they engage in cooperative security alignments. When a collection of states facing a similar threat environment are able to minimize the risk of defection and ensure effective coordination, they can engage in a division of labor where each state individually specializes in different military capabilities that, when brought together, still comprise a full spectrum military force. I substantiate these arguments with evidence from a new dataset on the distribution of military capabilities from 1970-2020 and find that 1) states in cooperative security alignments have more specialized militaries, and 2) cooperative security alignments with more closely aligned interests and higher vertical integration have a higher division of labor.

One, if by land and two, if by sea: Cross-domain contests and the escalation of international crises
- Forthcoming, International Studies Quarterly
Abstract
Technological advances have added cyber and space to the more traditional domains of human interaction (land, sea, air). These new domains arguably increase opportunities for conflict across, as well as within, domains. Cross-domain conflict is thus seen by many as an emerging source of international instability. Yet, existing systematic empirical research has little to say about how domains interact. This study introduces a new dataset of the domains in which nations took military action during 412 international crises between 1918 and 2015. Analysis of these data yields several surprises. Far from being rare, cross-domain interactions are the modal form of conflict in crises during this period. Nor is cross-domain conflict "new:" crises that play out in more than one domain were about as frequent (proportionately) in decades past as they are today. Cross-domain crises are also less violent and of no greater duration than crises between belligerents using similar means.

The Shadow of Deterrence: Why capable actors engage in contests short of war
- Revise & Resubmit, Journal of Conflict Resolution
- co-authored with Erik Gartzke, Jon R. Lindsay, and Peter Schram
Abstract
Recent trends increasingly place conflict in a ``gray zone'' between peace and war. Observers interpret gray zone conflicts as deterrence failures. New technologies or tactics---from cyber operations to ``little green men''---reduce the costs or increase the effectiveness of low-intensity aggression. But gray zone conflict could also reflect deterrence success. Credible prospects of retaliation encourage challengers to adopt less effective means of aggression. These dueling ``push-pull'' logics suggest contrasting conflict dynamics impacting stability. We develop a formal model that synthesizes both perspectives by analyzing deterrence success as variable, rather than dichotomous. In the model, the intensity of a challenger's provocation varies inversely with the credibility of the defender's deterrent threat. We empirically analyze Russian gray zone activity since the 1990s. Russia is more restrained, and less effective, against nations in or closer to NATO. The model suggests inherent trade-offs between stability and military potency in limiting the risk of escalation.

Planes, Trains, and Armored Mobiles: Introducing a Dataset of the Global Distribution of Military Ca
- Under review
This article introduces the Distribution of Military Capabilities (rDMC) dataset. It begins by explaining the value of collecting data on disaggregated national military capabilities, its scope, and the data collection process. I then identify some initial trends about changes in the distribution of military capabilities across states from 1970 – 2014. I conclude by identifying future research use of the data as both a dependent and independent variable.

Introducing the International Crisis Behavior Event (ICBe) Dataset
- co-authored with Shannon Carcelli, Rex Douglass, Erik Gartzke, Jon R. Lindsay, and Thomas Leo Scherer
Abstract
How do international crises evolve? There are significant data and measurement challenges in seeking answers to this critical question. We conceive of international affairs as a strategic chess game between adversaries, which demands a way to systematically measure pieces,moves, and gambits accurately and consistently over different contexts and periods. We develop such a measurement strategy with a crisis-specific ontology of actions and interactions and apply it to the corpus of 470 crisis narratives developed by the International Crisis Behavior (ICB) Project. Our ontology has high coverage, capturing thoughts, speech, actions, and interactions by actors. These data exhibit high accuracy with multiple human codings per sentence of each narrative. We then evaluate the resulting ICBe dataset by comparing it to prominent state-of-the-art datasets using existing strategies for measuring conflict processes. We find that ICBe captures the process of a crisis with greater accuracy and granularity than events or crisis datasets.
Cruisin’ for a Bruisin’: Domestic Political Constraints, Suboptimal Military Strategies
- co-authored with Kerry Chavez
Abstract
Democracies are thought to be superior war-fighters because of their rational publics, accountable leaders, and stringent self-selection into wars. This finding does not seem to hold in unconventional contexts, specifically in civil conflict interventions dubbed ‘wars of choice’ as the epitome of wars of self-selection. Existing literature cites military myopia, a cultural argument, and capital-rich force structures, an economic hypothesis. Both assume a flawed elite actor and fail to explain the variation in selection and prosecution of wars of choice. We introduce a theory that brackets both actors and stages, modeling rational incentives and constraints of political and military actors to explain the conditions under which they select suboptimal strategies. Using a formal model and original data on all militarized interventions since 1989, we demonstrate that domestic political constraints constrict democratic intervenors to risk-mitigating strategies through high technology. High-tech approaches are usually poor counter-strategies in unconventional conflicts, resulting in not only reduced progress but retrogression of political objectives. This contributes to the literature by examining the strategic interaction of democratic intervenors and their civil adversaries, providing a more comprehensive explanation for democracies’ inferior strategy choices and their consequences.

Churning Butter into Guns: Identifying Latent Military Capacity
- co-authored with Rex Douglass
Abstract
Military capacity is considered central to national power, yet its measures remain aggregated and generalized. This paper aims to produce a better understanding of military capacity through a nuanced analysis of military technology. The acumen of these technological bundles determine the military systems available to a given country and thus shape military strategy, structure, and success. This paper introduces new data using the DoD's Militarily Critical Technologies List (MCTL) to shed light on the composition of technological bundles as well as empirically identifying military domains based on technological portfolios. This new way of thinking about military technology through empirical validation rather than non-military proxy will shed light on nations' system integration skills, the complementarity and substitutability of military technologies, and the role that alliances, trade ties, and domestic factor endowments play in shaping a military's technological portfolio.
