Resursa umană implicată
Grupul de cercetare condus de către Prof. dr. Simion
Aştilean cuprinde cadre didactice din catedra de Spectroscopie
Moleculară: Prof. dr. Traian Iliescu, Conf. dr. Dana
Maniu, Conf. dr. Simona Cintă, Conf. dr. Monica Baia,
cercetători post doctorat: Dr. Felicia Toderaş, Dr. Cosmin
Farcău, Dr. Rareş Ştiufiuc, Dr. Francois Guedje (Benin, bursier
AUF), studenţi doctoranzi: Drd. Monica Iosin, Drd.
Valentin Cânpean, Drd. Monica Potara, Drd. Sanda Boca,
Drd. Mircea Giloan, Drd. Milohumm Dzagli (Togo, bursier
AUF) şi studenţi de nivel master sau licenţă. Putem afirma
că prezenţa tinerilor cercetători reprezintă atuu-l esenţial al
poveştii noastre de succes. Numărul relativ mare al tinerilor
este un obiectiv îndeplinit prin câştigarea în ultimii ani a
unor proiecte de cercetare, multe dintre acestea fiind proiecte
cu CNCSIS. Grupul deţine în prezent o resursă umană de
excepţie, având competenţe în câteva domenii noi, unele
abordate aici în premieră naţională cum sunt plasmonica,
nanofabricaţia asistată de metode de nanolitografie, sinteza
si autoasamblarea nanoparticulelor, analiza suprafeţelor la
scara micro- si nano- prin combinarea microscopiei Raman
confocale cu microscopia de forţă atomică (AFM). Mai
mult, datorită caracterului interdisciplinar al cercetării,

The research group directed by Prof. dr. Simion Astilean
comprises the permanent staff from the Department of Molecular
Spectroscopy: Prof. Traian Iliescu, Assoc. Prof.
Dana Maniu, Assoc. Prof. Simona Cintă, Assoc. Prof.
Monica Baia, the post-doc researchers: Dr. Felicia Toderas,
Dr. Cosmin Farcau, Dr. Rares Stiufiuc, Dr. Francois Guedje
(from Benin, AUF scholarship), many current PhD students:
Monica Iosin, Valentin Canpean, Monica Potara, Sanda
Boca, Mircea Giloan, Milohumm Dzagli (from Togo, AUF
scholarship) as well as a number of master and undergraduate
students. The presence of young researchers in the
group represents the key of our success story. Their relative
large number was a permanent objective which has been accomplished
due to the financial support from grants and
projects, many of them with CNCSIS. The human resource
in our group offers a high level of competences in research,
some of research fields being new in Romania, like plasmonics,
nanofabrication methods assisted by nanosphere lithography,
synthesis and self-assembling of nanoparticles as
well as surface analysis at micro- and nanoscale by combining
confocal Raman microscopy and AFM.
In addition, due to the interdisciplinary of the research,
the Prof Astilean group works successfully in partnership
with many colleagues from other departments in physics as
well as in biology, chemistry, pharmacy and medicine, from
Romania and abroad.
