PROFESSIONAL BIOGRAPHY
Stefano Spezia born in Erice (Italy) in 1981, he obtained a master’s degree in Electronic Engineering (Telecommunications) at the University of Palermo in 2006. At the same university in 2008, he received his diploma of specialization in secondary education for “Mathematics and Physics”. In 2012 he obtained the Ph.D. degree in Applied Physics. From 2007 to 2014 he carried out research in Physics of Complex Ecological Systems, in semiconductor Spintronics, in Nonlinear Optics and in Quantum Optics, publishing several works both in international journals and in books. Since 2014 he is a teacher of Mathematics and Physics in Italian secondary school. Since 2018 an amateur mathematician, OEIS contributor.
