### Broad strokes
Generally, my research interests falls into two areas:
- How can we do inference in the presence of interdependent observations
- Estimating and utilizing an underlying "social space" from an observed network
### Inference
#### standard dyadic design
Much of international relations data consists of:
- a set of units or nodes
- a set of measurements, $y_{ij}$
### Inference
#### the problem
GLM: $y_{ij} \sim \beta^{T} X_{ij} + e_{ij}$
Networks typically show evidence against independence of {$e_{ij} : i \neq j$}
Not accounting for dependence can lead to:
- biased effects estimation
- uncalibrated confidence intervals
- poor predictive performance
- inaccurate description of network phenomena
### Inference
#### evaluation of solutions
### Inference
#### Measuring effect of boko haram
with Cassy Dorff & Max Gallop (forthcoming in Journal of Politics)
### Measuring Social Space
- Many political theories often refer to constructs that can not be observed directly
- As a result, political scientists have come up with latent indicators of everything from:
- ideological disposition of survey respondents
- legislators
- judges
### Social space
#### asymmetric relations from a symmetric network
with Arturas Rozenas & John Ahlquist (Political Analysis [2019])
### Social space
#### strategic determinants of foreign aid
with Cindy Cheng (forthcoming in British Journal of Political Science)
### Social space
#### ccp advancement
with Narisong Huhe & Max Gallop
### Social space
#### predicting subnational intrastate conflict
with Cassy Dorff & Max Gallop (Forthcoming International Studies Quarterly)
### multilayer nets
- Networks that evolve over time or sets of networks that may evolve together over time provide interesting modeling opportunities
### Multilayer networks
#### evolution of cooperation and conflict
with Peter Hoff & Michael Ward (Journal of Peace Research [2016])
### Multilayer networks
#### Measuring state preference
with Max Gallop
### Multilayer networks
#### Measuring Influence
with Peter Hoff & Michael Ward
### What's next
- Mostly, continuing along the lines of what I've discussed
- Also playing with agent based models a bit to derive some empirically testable insights
