The theoretical study of realistic systems of interest in l
ife sciences or nanotechnology is possible only if the contrasting goals o
f high accuracy and low computational costs are met. Despite its success a
nd increased popularity\, DFT fails at times in the ultimate goal of being
a predictive tool. For this reason\, development of alternative electron
correlation methods is still a very active area of research in Quantum Che
mistry. This talk starts with an overview on some of the computational tec
hniques developed around the paradigm of multiconfigurational WFT. Several
key elements are discussed. First\, how such methods can be useful for th
e study of strong correlation in molecules. Second\, the way we can build
robust multiscale approaches on top of WFT in order to dissect electron co
rrelation effects into components of different characteristic length-scale
. The talk will end with a presentation of some ideas aimed at the design
of a new class of DFT functionals with the help of information from WFT.**\n\nAbout the speaker — Francesco Aquil
ante holds a PhD in theoretical chemistry from Lund University with a thes
is on the development of the so-called ab initio Density Fittin
g from Cholesky Decomposition approximation.After a postdoctoral stay at G
eneva University\, he became an independent researcher at Uppsala Universi
ty and then obtained a grant from the Italian Research Ministry to carry o
n his work at the University of Bologna. He is now completing a second res

AS quantum chemistry software\, his expertise spans from multiscale techni
ques for excited state calculations to the treatment of strong correlation
in molecules through electron correlation methods and novel density funct
