-the vast majority never attract even a second contributor. I am
-particularly interested in how the design of communication and
-information technologies shape social outcomes like the decision to

-online communities that make failures of collective action newly
-visible with ``big data'' research methods from software engineering
-to answer fundamental social scientific questions.

-Seeking to understand the determinants of collective action, my
-research has been driven by three overlapping themes: (1)
-population-level observational studies comparing failures to build
-communities to the rare successful attempts; (2) attention to the role
-of reputation and status in collective action; and (3) analyses of

-\section{Population-Level Observational Studies}
+I study collective action in online communities and seek to understand
+why some attempts at collaborative production -- like Wikipedia and
+Linux -- build large volunteer communities while the vast majority
+never attract even a second contributor. I am particularly interested
+in how the design of communication and information technologies shape
+fundemental social outcomes with broad theoretical and practical
+implications -- like the decision to join a community or contribute to
+a public good. My research is deeply interdisciplinary, consists
+primarily of ``big data'' quantitative analyses, and lies at the
+intersection of sociology, communication, and human-computer
+interaction.
+
+Using Internet-based peer production projects as my research settings,
+my work seeks to understand the conditions for collective action using
+observational data from real communities. This work has been shaped
+by three complentary approaches: (1) the comparison of failures to
+build communities to rare successful attempts through the use of
+projects as the unit of analysis; (2) attention to the role of
+reputation and status in the mobilization of volunteers; and (3)
+analysis of design changes as ``natural experiments'' building a
+deeper, and often causal, understanding of social processes using
+observational data. Nearly all of my work incorporates at least two of
+these approaches.

+\section{Projects As Unit of Analysis}
Although there have been many thousands of studies of online
-collective action and peer production, the vast majority of these
-studies have only considered successful projects like Wikipedia and
-GNU/Linux. The majority of research on collective action -- both
-online and off -- has only considered projects that have successfully
-mobilized contributors. In this sense, most previous analyses of
-collection action have systematically selected on their dependent
-variable. Most of my research treats projects as the unit of analysis
-and mobilization as the dependent variable, comparing successful
-examples of collective actions to failures.

\section{Reputation and Status}
Although empirical research comparing successful and unsuccessful peer
-projects has been rare, theories offering to explain the success of
-collective action online have been widespread. No theory has been more
-influential or widespread than the suggestion that, in the absence of
-pecuniary rewards, engagement in collective action in online
-communities is driven by the possibility of increased reputation and
-status conferred upon contributors to an online public good.

\section{Design-Driven Natural Experiments}
+Although nearly all of my work has important implications for the
+design of socio-technical systems, I have structured much of my work
+around the evaluation of technological design changes. In several
+papers, I treat design changes as ``natural experiments'' that
+exogenously change the ways that social structure is enacted. By doing
+so, I can both build causal understandings of social phenomena from
+field data, and can tighten the distance between theory and design.

For example, to evaluate the impact of status-based incentives and
collaboration in Scratch, I use a regression discontinuity framework
-to measure the causal effect of increased status for collaboration in
-Scratch \cite{hill_causal_2012}. In that study, which I am preparing
-for submission to a communication journal this fall, I show that the
-highlighting the work of the authors of collaborative projects on the
-Scratch web page (see the bottom of Figure \ref{fig:scratchfrontpage})
-resulted in more collaboration but also caused a decrease in the
-amount of total effort exerted by contributors. Speaking to
-fundamental sociological work in the literature on collective action,
-I present evidence that this decrease is driven by both an the influx
-of new contributors and a decrease in the effort and contributions of
-established contributors.

-In other papers, I have helped analyze sales records of hobbyists

-lead to large increases in the proportion of women contributors

My research agenda involves further exploration of the determinants of
collection action online -- especially using a series of large new
-datasets I have built in my dissertation research. I plan to both
-continue this research trajectory and to create new social and
-technical infrastructure that will allow others researchers to join me
-in the type ``big data'' observational research in active communities
-that my research involves. This section outlines some future
-directions I plan to explore.
-
-\emph{Toolkits for Experimental Social Design} -- My research has been
-possible through relationships I have with a series of organizations
-with large active online communities (e.g., the MIT Media Lab and the
-Wikimedia Foundation). These organizations, like many others, make
-design changes to the software that supports their communities to
-encourage contributions and improve aspects of their users'
-experiences. Most of the time, these organizations have very little
-idea if these changes work. I plan to build on my own experience
-evaluating natural experiments in online communities to create a
-technical framework, and a network of academic and practitioner
-collaborators, to facilitate well-designed experiments by the hosts of
-large online communities and a system for data sharing that allows for
-academic evaluation of these experiments.

+research trajectory and to create new social and technical
+infrastructure that will allow others researchers to join me in ``big
+data'' observational research with active communities. This section
+outlines some future directions I plan to explore.
\emph{Understanding the Relationship Between Collective Action and
Performance} -- My work has treated collective action and production
as ends in themselves and has largely avoided the consideration of
-issues of performance, efficiency, or quality. Using my existing
-datasets, I will compare the performance of collaborative production
-to individually produced works to understand when successful
-collection action leads to higher performance or quality. In a
-manuscript currently under review using data from Scratch, I show
-important limitations of collaboration in remixing quality,
-particularly in regards to more artistic or media-intensive projects
-\cite{hill_cost_2012}. I will further explore this direction in future
-work.
-
-\emph{Integrated Theory of Design for Collective Action} --
-My studies of status provide a detailed understanding of the dynamics
-of collection action in relation to one important independent
-variable. In future work, I plan to evaluate the effect of governance
-and different systems of authority, framing, modularity and project
-complexity. In the long term, I hope to work toward a broad set of
-principles of design for collection action and community.
-
-In graduate school, I have been fortunate to collaborate with many
-co-authors in many academic departments and I intend to continue this
-tradition going forward. In sum, my research uses design to contribute
-to social scientific theories of collective action, and using theories
-of collective action to influence design and offers implications and
-opportunities for a broad range of disciplines and fields.
