Research
My scientific interests are mainly related to gravitational lenses. At present,
I work on weak lensing in clusters of galaxies. From a theoretical point of
view, I have discussed in detail the methods and the noise properties of
lensing mass reconstructions (see [2, 3, 12] in the list of publications). In
particular, I have shown that the reconstruction method known as “noisefiltering” produces optimal reconstructions, i.e. mass maps with the largest
signal-to-noise ratio; I have also provided a new, very fast numerical implementation of that method based on a simple variational principle [6].
Moreover, I have outlined two new applications: determination of cosmological parameters from weak lensing observations [4] and detection of the
coupling effect of a double lens [7]. From an observational point of view, I
have detected a weak lensing signal in distant galaxy clusters observed by
VLT [8].
A second research interest involves molecular clouds. In particular, from
an observational point of view, I have produced wide field extinction maps
of cloud complexes using an optimized, multi-band technique [11]. I also
have focused on stability issues of cloud cores, generalizing a classical
results to non-symmetric cores [10].
Recently, I have also considered from a statistical point of view the interpolation of discrete data into a smooth field [9, 14, 15]. This problem,
which occurs very often in Astronomy, has been solved exactly for a large
family of interpolation techniques (linear interpolators).
I collaborate with The Astrophysical Journal Letters and Astronomy &
Astrophysics as a referee.
Teaching
In April 2002 I held a brief course (10 hours of class) on Astrophysical
applications of General Relativity at the Physics Department of the University of Milan addressed to graduate students.
Computer Skills
I have carried out scientific projects using many different languages, from
Pascal, to C/C++, Fortran, Java, LISP, Haskell. Besides, I have some notions of data bases and experience in lexical analyzers and parser generators. I also have several years of experience as system manager on Unix
machines (in particular on the Unix-like operating systems AIX, Solaris
and Linux).
Data reduction
In the last years, I have acquired familiarity with image manipulation and
data reduction tools, such as IDL, IRAF, SExtractor, and IMCAT (used for
the lensing analysis).

I love traveling and spending time in different places. I like playing piano
and violin, and listening to classical music. I practice several sports: skiing, swimming, wind-surfing, and SCUBA diving. During the summer I
practice some mountaineering and speleology.
