Matthew A. Hammer
As of Fall 2015, I am an assistant professor in the Department of Computer Science at University of Colorado Boulder.
I am a co-director of the CU Programming Languages and Verification group (CUPLV).
Research Interests(Also see my drafts and publications page).
Research on programming languages provides invaluable lenses that connect human understanding with computational phenomena.
In particular, I'm interested in designing PL-based abstractions for settings in which humans and computers cooperate to create and process information.
Incremental computationsattempt to exploit input similarities over time, reusing work that is unaffected by input changes.
Adapton offers a unified model for eager and lazy incremental computation, including a general-purpose demand-driven change propagation algorithm.
To maximize this reuse in a general-purpose programming setting, programmers need a mechanism to identify dynamic allocations (of data and subcomputations) that correspond over time. Nominal Adapton (OOPSLA 2015) offers a notion of names which is formal and general. The Fungi language offers an associated type and effects system for programs that deterministically generate and use unique names.
Interactive computationsreside in an open world, where future states are explored collaboratively with an external user. Common examples include spreadsheets, development environments, video games and media processing (graphics and sound).
Secure multi-party computationconsists of computation performed by mutually-distrusting agents; together, they cooperatively compute functions over their private data, while only ever learning certain prearranged results and while remaining otherwise oblivious to the computational steps necessary to produce them.
Funding AcknowledgmentsMy research has been funded through various sources, both past and present:

Short biographyBefore joining CU, I was a postdoc researcher working with Michael Hicks, Jeff Foster, David Van Horn and the PLUM group at the University of Maryland. As a PhD student, I was advised by Umut Acar at the University of Chicago as well as a visiting student at the Max Planck Institute for Software Systems in Kaiserslautern, Germany.
As a student intern, I spent summers at IBM Research in Almaden and Intel Research in Santa Clara. I received my B.S. in 2005 from the University of Wisconsin with a major and honors in computer science.
