Biography

Ian 2014-present: Bell Labs Access Research Engineer, Access Hardware Platforms group, Fixed Networks, Bell-Labs Alcatel-Lucent
     •    Research in the direction of hardware accelerators

Aug. 2010 – Dec. 2013: Postdoctoral researcher, Semiconductor Physics Laboratory, Physics Department, KU Leuven
     •    Investigation of defects at the atomic level using the electron spin resonance technique.
     •    My research relevant for fields as solar cells, flash memories, CMOS technology, photonics, nanosensors, geological sediments dating, etc.
     •    Studied structures include single-crystal arrays of Si nanowires, Si or Ag nanoparticles either freestanding or embedded in different amorphous oxides, magnetic polymers, interfaces of crystalline semiconductors with oxides, GeSn, SiO2 nanosprings etc.
     •    The effect of irradiation (VUV, UV, gamma-rays, X-rays, etc.), thermal, and chemical treatments on the various structures is studied using the paramagnetic defects as atomic probes.
     •    Results dissemination through different channels to a diverse international audience, actively attending prestigious international conferences (as an invited speaker, oral, and posters presentations) and coordinating meetings with international collaborators.
     •    Knowledge transfer; guiding Ph.D, master, and undergraduate students.
     •    Help colleagues to solve technical problems; equipment troubleshooting.
     •    Organize measurements in the research group during meetings with the head of the laboratory.

Aug. 2010 – Dec. 2013: Researcher in the IWT project SiLaSol, focused on novel concepts based on all-Si multi-gap solar cells and reducing the Si use by kerf- loss-free wafering technology. During this time I worked closely with members of the solar cell group in imec and universities in Flanders investigating properties of the proposed structures and recommending improvements.

Nov. 2005 – July 2010: PhD student, Semiconductor Physics Laboratory, Physics Department, KU Leuven
     •    Research was focused on the interfaces of Si nanoparticles with the embedding oxide fabricated by different techniques, fundamental investigation of E'd defect in amorphous SiO2, photoresist layers, low-k oxides etc., as studied by electron spin resonance techniques.
     •    Guided undergraduate and master students with individual laboratory projects.
     •    Instructed 1st year students for the experimental physics laboratory.
     •    Took care of the library of our research group.

Jan. 2005 – Nov. 2005: Researcher at National Institute for Research and Development of Isotopic and Molecular Technologies, Cluj-Napoca, Romania
     •    Literature research on isotopes.

Feb. 2005 – Aug. 2005: Erasmus mobility program in Leuven
     •    Research the colossal magnetoresistance behavior of perovskite nanowires

    Apr. 2003 – Ian. 2005: Technician at the Civil Protection Inspectorate Cluj-Napoca, Romania

Honors and Awards

•    Best poster award at the Advanced Spectroscopies on Biomedical and Nanostructured Systems, Cluj-Napoca, Romania, 3-6 September, 2006
•    Multiple prizes at the Romanian National Olympiad in the period 1993-1999.
