He is the author of about 300 research papers in nonlinear analysis and several books, including Variational and Nonvariational Methods in Nonlinear Analysis and Boundary Value Problems (Kluwer, 2003), Singular Elliptic Problems: Bifurcation and Asymptotic Analysis (Oxford University Press, 2008), Problems in Real Analysis: Advanced Calculus on the Real Axis (Springer, 2009), Variational Principles in Mathematical Physics, Geometry and Economics: Qualitative Analysis of Nonlinear Equations and Unilateral Problems (Cambridge University Press, 2010), Nonlinear PDEs: Mathematical Models in Biology, Chemistry and Population Genetics (Springer, 2012), Partial Differential Equations with Variable Exponents: Variational Methods and Qualitative Analysis (CRC Press, 2015), Variational Methods for Nonlocal Fractional Problems (Cambridge University Press, 2016). He was a Highly Cited Researcher (2014). He was elected to the Accademia Peloritana dei Pericolanti (2014) and to the Accademia delle Scienze dell’Umbria (2017).
