What I'm up to...

September 2018:
After enjoing the reversibility week in Leicester I visited Ivan Lanese in Bologna where we worked on interesting stuff related to reversibility and open choreographis with Franco Barbanera.
July/August 2018:
BehingAPI in Leicester together with Hernan Melgratti, Carlos Pombo, and Agustin Sune from UBA ...but having fun at Discotec 2018 in Madrid
June 2018:
End of my study leave :(
...but having fun at Discotec 2018 in Madrid
February 27 - March 4 2018:
Heading to Malta to visit Adrian Francalanza and kick off BehAPI.
February 20 - 23 2018:
Working at IMt with Claudio Mezzina and Adrian Francalanza on reversibility and monitoring in Erlang.

This is just because I don't like facebook...


Research

Brief CV

I graduated (1998) and got my PhD degree in Computer Science (2003) at the department of Computer Science, University of Pisa. In October 2005, I joined the University of Leicester as a Lecturer of the Department of Computer Science. Before joining Leicester, I have been a research associate (2003-2005) at the Dipartimento di Informatica (University of Pisa).

Interests

My main research interests are in theoretical and applied aspects of distributed and mobile systems. Recently I've been working on automata- and type-based models of distributed choreographies, contract- and graph-based models of distributed interactions, and on nominal automata.

Publications

  • My papers can be found on DBLP
  • A new semantics of global view of choreographies (with R. Guanciale; the published version is here): We recently propose two abstract semantics of global view of choreographies given in terms of partial orders. The first semantics is formalised as pomsets of communication events while the second one is based on hypergraphs of events. These semantics can accommodate different levels of abstractions, is more general than many of the existing proposals, and it can be easily twicked to capture different types of communication (e.g., out-of-order output). We discuss the adequacy of our models by considering their relation with communicating machines, that we use to formalise the local view.
  • Unpublished manuscripts:
    • Choreographies for Automatic Recovery (with C. A. Mezzina): We propose a choreographic model of reversible computations based on a conservative extension of global graphs and communicating finite-state machines. The main advantage of our approach is that does not require to instrument models in order to control reversibility but for a minor decoration of branches. We show that our models are conservative extensions of existing ones and that the reversible semantics guarantees causal consistency.

Projects

I'm currently collaborating in the following projects:

  • BehAPI (EU RISE Action, co-PI + site and WP4 leader) due to start in March 2018; I am WP and UoL site leader
  • RCADE (EU MSCA Fellowship, co-PI) Claudio Mezzina will join in September 2018 our department as MSCA fellow collaborating with Irek Ulidowski and me on causal consistency reversible debuggers
  • Reversible Computation (EU Cost Action)

I have contributed several the Leverhulme project Tracing Networks, several EU-funded projects (PROFUNDIS, AGILE, and DEGAS) as well as some Italian projects (COMETA, SP4 and NAPI).

Past grants and collaborations to research projects

  • BETTY EU COST Action (RTD Framework Programme).
  • Sensoria (IST project funded by the EU as Integrated Project in the 6th Framework Programme (FP6) as part of the Global Computing Initiative (GC))
  • HiDe4SOC (Nuffield Foundation ref. NAL 32612, PI)
  • Tracing Networks (Levehulme Trust, co-PI Jobs available: check-out the project webpage)
  • PAIS (Process Algebras for Interaction and Spatiality) British-Italian Partnership Programme for Young Researchers (British Council and CRUI, co-PI)

Hacking my email address

Nominal calculi
	      My email may be hacked in
	      pi-calculus as on the right.

	      I'm pretty sure that you can understand my
	      email address above even though you ignore
	      process  algebras.
	    
	      (new uid, dom) (
	      uid(x).dom(y).mail![x@y]
	      | (uid![et52] + uid![emilio])
	      | dom![le.ac.uk]
	      )
	    
Synchronised Hyperedge Replacement
	      Here is my SHRish address.

	      As a simple exercise, you can find what should
	      be written for '???' in  the last transition.

	      Another exercise is to add a rule to make the
	      SHR representation of my alias 'emilio' ad done
	      for the pi-calculus version of my email.
	    
History-Dependent Automata
	      Well it might look complicated from the picture...
	      but, believe it or not, the HD-automata correspondes
	      to the pi-calculus representation.

	      Notice that the red arrow represents a transposition
	      of 'et52' and 'emilio'.
