Historically, mathematics has been used extensively in the
sciences to describe, explain, and ultimately predict the behaviour of complex
systems. Starting from the seventies, models have been used widely also to
study complex biological systems and to understand the fundamental biological
mechanisms. Mathematical, computational, theoretical modelling approaches
have been used for example to represent hypotheses (i.e., circulation in physiology),
to test theories, to make predictions (i.e., pharmacological response to a
drug), to design outcomes (i.e., intake determination for optimal growth),
and to analyse data. Independently from the specific application and from
the specific modelling/computational techniques, the common denominator of
this area is the use (and the integration) of methodologies/tools coming from
the statistics, the mathematics and the artificial intelligence to derive
qualitative information about the main variables of the biological system
or to make quantitative prediction of the phenomena under
investigation. The research in this field requires the integration of different
competences ranging from the dynamic system theory to the stochastic processes,
from the numerical analysis to the statistics, from the medicine to the biology.
In this context, our research activities are mainly focused on the ordinary
differential equations and on the compartmental models, on the nonparametric
modelling of temporal profiles and surfaces, and, more recently, on the gene
regulatory networks.
A particular attention is devoted to the use of stochastic models and to the
Bayesian approaches and Markov Chain Monte Carlo methods for the quantitative
estimation of the parameter of a model into a framework characterised by different
sources of uncertainty. Classical problems related to the identification of
parametric models, as the a-posteriori identifiability, are tackled in different
contexts. Some of the developed applications have required the definition
of pharmacokinetic and pharmacodynamic models. Other ones have required the
development of in vitro/in vivo models for an early evaluation of the potency
of an antitumor agent during the development process of the drug. Moreover,
the analysis of data coming from a population of subjects and the consequent
modelization of the inter-individual variability is one of the most interesting
topics of our research. The estimation of non measurable biological signal
by using deconvolution stochastic techniques is a further topic on which we
are working.
