 As usual, the professor is not the one doing the real work. Please read on for more details on our research. It has received international recognition by the fact that Wolfgang has won the [[ http://www.aito.org/Dahl-Nygaard/2008.html | Dahl-Nygaard Award]] in 2008.

+My PhD research focused on investigating programming language support to deal with the effects engendered by partial failures in mobile ad hoc networks (MANETs). In MANETs many partial failures are the result of temporary network partitions due to the intermittent connectivity of mobile devices. Some of these failures will be permanent and require application-level failure handling. However, it is impossible to distinguish a permanent from a transient failure. Leasing provides a solution to this problem based on the temporal restriction of resources.

+This research identified a number of criteria for a leasing model specially designed for MANETs and proposes the //leased object references// model which exhibits such criteria. Leased object references combine leasing with asynchronous communication into one coherent language abstraction that deals with both transient and permanent disconnections. We explored a language approach where dedicated language support is provided such that low-level leasing management concerns (e.g. lease renewal) can be abstracted away, and enables both lease holders (clients) and lease grantors (services) to deal with permanent failures.

 This poses a problem when we look at the new generation of disposable processing hardware, such as RFID tags. Ubiquitous applications will not only consist of peer-to-peer interactions, but will have to deal with clouds of volatile information disseminated in the network by omnipresent devices such as RFID tags or sensors.
-I am currently looking into programming abstractions that allow to specify which events to capture by distributed application components in a mobile ad hoc network. Furthermore, I am trying to come up with mechanisms that allow reacting to these events without relying on event handlers or other callback mechanisms. Finally, low level events should be processed (e.g. by combining them) such that they are on the semantic level of the application.

 My research intends to provide abstractions that bind a number of services residing on different mobile devices into coherent entities. Programmers can then use these abstractions to communicate with groups of services as easily as with single services.

-The goal of my research is the development of elegant programming models which allow applications to respond to dynamic changes in their environment. As a means to detect such changes, we explore the [[crime:factspaces|Fact Space Model]], which provides a means to reason about one's current context.
-My ongoing research investigates which abstractions can be used to handle the events produced by an implementation of the fact space model. An interesting path that I am currently exploring is the use of [[research:recap|reactive context-aware programming]].
+My research focuses on investigating programming language support to deal with the massive amount of concurrent events generated by various input devices. By providing adequate software abstractions for correlating multiple input devices we try to encourage multimodal gestural interaction and ease their implementations.
+The relation of my research and AmOP is the //spontaneous collaborative manipulation of digital information//. One scenario is that multiple people can interact using their laptop or mobile device with a shared virtual smart-board over a wireless network. Another scenario is the peer-to-peer data exchange where one users 'throws' (gesture 1) data and another users 'catches' (gesture 2) it. This type of interaction is both distributed in the //actions// they perform (correlate the 'throw' and 'catch' from different devices) and in the //data// that is exchanged.

 The use of weak data replication in a mobile environment ensures that there is no need to stop an ongoing application when certain data cannot be synchronized.

- In an Ambient Intelligent setting, various kinds of hardware are involved, each with its own characteristics. To allow abstraction over the different devices, a standard virtual machine approach is not feasible because it is not possible to abstract over all the devices at the same time. Instead, each device will require an individually adapted virtual machine.
-This reseach proposes a new way to develop virtual machines for Ambient Intelligence. Instead of manually modifying the virtual machine for of a particular device, the virtual machine can be generated by composing reusable modules. The first step is to determine the set of modules that can be used to build a virtual machine. The next step is to find implementation and composition techniques that guarantee the correctness and efficiency of the generated virtual machine.

+In the past, I have contributed to the formulation of the ambient-oriented programming paradigm and have co-designed the current incarnation of AmbientTalk.  Currently, my research focus is the study of elegant mechanisms to allow applications to respond to dynamic changes in their environment.
+A first element of the solution I propose is the use of pattern matching rules to succinctly describe which changes to the environment are relevant.  Applying such rules over a [[crime:factspaces|federated fact space]] -- which transparently combines the information provided by all reachable devices -- proves to be a declarative means to coordinate and contextualize the behavior of distributed applications.
+The second element of the proposed solution is the use of [[research:rp|reactive programming]]: a programming model centered on the use of time-varying //reactive values//. Their unique //contagion// semantics allow building event-driven software without any event handlers, thus avoiding the problems engendered by inversion of control.
+The approach that combines and integrates these elements is the  [[research:recap|reactive context-aware programming]] paradigm, an extension of the ambient-oriented programming paradigm which is tailored for the Internet of Things.
