PUBLICATIONS
=============

In computer science it is often the case that a paper appears in a
conference with published proceedings first, usually in a reduced form,
and then the corresponding full version appears in a journal. In such
cases here we list both publications.

- paper appeared exclusively in journals: 7,

- paper appeared exclusively in conferences: 10,

- papers appeared in both: 11.

GRANTS
=======

- Principal Investigator of the research project *Uno studio organico
sull'efficienza computazionale: analisi teorica e sperimentale*.
\"Progetto Medio di Ricerca di Ateneo\", Sapienza 2017.
N. protocollo RM11715C67E8C374

- In 2015 I have been awarded one Newton International Fellowships, to
fund a two year postdoc position at the University of Edinburgh. In
the end **I did not accept** the fellowship to accept a job offer at
UPC in Barcelona.\
The fellowship is awarded on the basis of scientific record and of a
research proposal to be developed in a chosen host UK institution,
and funds two years of postdoc position at that institution. The
award scheme is run by The British Academy and the Royal Society.\
In 2014 only 40 fellowships have been awarded across all disciplines
in the physical, natural and social sciences and the humanities.

- The PostDoc position in Prague (2011) was awarded by the Eduard ech
Center for Algebraic and Geometry on the basis of my own research
proposal.
