Cercetare

"If you get a letter of recommendation that counts number of publications, rather than commenting substantively on a candidate's contributions, ignore it."

David Lorge Parnas: "Stop the Numbers Game. Counting papers slows the rate of scientific progress" , Communication of the ACM , November 2007.

Următoarele subiecte tehnice și științifice au fost în centrul preocupărilor mele în ultimele decenii:

• Real Complexity
• Integral Parallel Computation
• Parallel I/O System
• The Supra-Linear Condition for Parallel Computation
• The Algorithmic Complexity & Digital Circuits
• 0-State Universal Turing Machine
• The Connex Project
• Lisp Machine
• Functional Information
• Loops & Recursive Functions
• Loops & Formal languages
• Loop Based Taxonomy for Digital Systems
• Virtual Multi-Processor

În același timp, conștient și de problemele non-tehnice, am scris următoarele texte:

• Ethos - Pathos - Logos.
• Limite care deschid. Eseuri despre o lume avida de intelesuri si coplesita de complexitate (Opening Limits. Essays about a world hungry of meanings and oppressed by complexity), a collection of texts published in the last few decades (in Romanian).
• Structural-Phenomenoligical Modeling papers in Noesis
• "Profunzimile Existentei" in filosofia secolului XX un text ce poate explica in mare masura de ce aceasta sub-sectiune a paginii web exista.
• "Integral Humanism" in Intercultural Humanism Challenges, Experiences, Visions, Strategies, Oxford, 9-12 September 2010.

Învățământ

• Electronică Funcțională
• Circuite Integrate Digitale
• Sisteme cu Auto-organizare (în Universitatea Politehnica din București)
• Sisteme Digitale Avansate (Master Infineon în Universitatea Politehnica din București)
• Arhitecturi de Calcul (în Universitatea Politehnica din București, Universitatea TRANSILVANIA din Brașov, St. Mary's College of Maryland)
• Teoria Computației (St. Mary's College of Maryland)
• VeriLab

Politică

Următoarea problemă politică m-a hărțuit în scurta mea implicare politică ca membru în Guvernul Petre Roman 2:

• Reforma Educației: lupta mea fără de succes cu reforma conservativă a societății românești în anii 1990 - 1991

Implicare civică

Implicarea mea civică este o urmare a scurtei mele aventuri politice. Au rezultat niște acțiuni și opinii sporadice referitoare la (prea) veșnicele probleme românești:

• Proiectul iDemocracy
• How to make the most appropriate distinction between instruction, training and education in the Romanian educational policy. See an uneducated opinion in: "Invatamantul la orizontul 2020" published in Romania 2020, Ed. Compres, 1998.
• Do we expect the professional ethos to trigger improvement in our society? A preliminary answer in the short inaugural statement drafted as board member of IPID (Institutul de Proiecte pentru Inovatie si Dezvoltare): "Dezvoltare Integrativa & Ethos Profesional"
• In order to increase the chance of the young inventors to promote their ideas I co-initiated and I'm supporting I-CUBE as member in the advisory board.
