Negotiations and Labor Relations are my specializations, which I introduced and taught at the Athens University of Economics and Business (OPA). During this time, and afterwards, I participated as a trainer and as a consultant in many companies, such as: the National Bank, IKEA, Hellenic Petroleum, Hellenic Aviation Industry, Public Power Corporations, Hellenic Defense General Staff. At the same time, I handled 200 cases of labor disputes during my 20-year activities as Mediator and Arbitrator at the National Organization for Mediation and Arbitration (OMED). In addition, I have taught in seven graduate programs at OPA for at least two decades and still teach in four of them. Besides these, I offer two training programs at the OPA's KEDIVIM:

(a) the Certificate In Negotiations (CIN: www.cin.aueb.gr, since 2012) and

(b) The Tailor-Made Negotiations (TMN: www.tmn.aueb.gr, from 2020)

Since 2020 I offer the Negotiations GPS (www.negotiationsgps.com), an electronic consulting possibility, through the OPA's Utilization Company.

My studies took place at ASOEE, Tubingen and West Berlin, from which I received my Ph.D. During my 35-year tenure at OPA, I have served three times as President of the Department of Organization and Business Administration and twice as Vice-President.
