Biografie
Sunt absolventă a Facultății de Biologie a Universității din București (2021) și am urmat studii de master în domeniul Biologiei, în programul de master Microbiologie aplicată și Imunologie, tot la aceeași facultate (2023).
În prezent, îmi desfășor activitatea la Universitatea din București, I.C.U.B, în Secțiunea Științele Vieții, Mediului și ale Pământului, unde îndeplinesc funcția de Referent de specialitate biolog. De asemenea, sunt implicată în activități de cercetare la Institutul Național de Cercetare-Dezvoltare pentru Științe Biologice, ocupând poziția de asistent de cercetare în biologie.
Domeniile mele de cercetare includ:
- Studiul aparatului enzimatic specific fungilor și implementarea de îmbunătățiri în producția unor enzime specifice, cu scopul utilizării lor ulterioare pentru biodegradarea ambalajelor utilizate în domeniul alimentar.
- Investigarea activităților antimicrobiene, antioxidante și a hemocompatibilității matricilor colagenice funcționalizate cu uleiuri volatile, cu scopul identificării unor noi aplicații topice pentru tratarea rănilor cronice la nivelul țesutului cutanat lezat.

RezumatCapitalizing on invasive plant species and stopping their aggressive spread might be achieved by using them as a renewable source of useful products such as cellulose. The study aimed to develop new cellulose-based food packaging materials with antioxidant and antimicrobial activity. The cellulose was extracted from the invasive plant species Robinia pseudoacacia pods, crosslinked with citric acid, used as reinforcement for polyvinyl alcohol (PVA) and functionalized with ferulic acid (FA). The obtained materials were characterized by XRD, ATR-FTIR, contact angle and SEM. The materials exhibited low solubility in water and the swelling degree was proportional to the FA content. The FA release from the matrix was assessed by HPLC and the antioxidant profile by CUPRAC, FRAP, and TEAC methods. The obtained materials inhibited the growth of bacteria, yeasts and molds, being especially active on Gram-positive bacteria and yeasts. Overall, the most promising formulation for further developing new packaging materials for products with water activity less than 0.95 was the one with the highest FA content. |

RezumatInterest in the extraction of phytochemical bioactive compounds, especially polyphenols from biomass, has recently increased due to their valuable biological potential as natural sources of antioxidants, which could be used in a wide range of applications, from foods and pharmaceuticals to green polymers and bio-based materials. The present research study aimed to provide a comprehensive chemical characterization of the phytochemical composition of forest biomass (bark and needles) of softwood species (Picea abies L., H. Karst., and Abies alba Mill.) and to investigate their in vitro antioxidant and antimicrobial activities to assess their potential in treating and healing infected chronic wounds. The DPPH radical-scavenging method and P-LD were used for a mechanistic explanation of the biomolecular effects of the investigated bioactive compounds. (+)-Catechin, epicatechin, rutin, myricetin, 4 hydroxybenzoic and p-cumaric acids, kaempherol, and apigenin were the main quantified polyphenols in coniferous biomass (in quantities around 100 mu g/g). Also, numerous phenolic acids, flavonoids, stilbenes, terpenes, lignans, secoiridoids, and indanes with antioxidant, antimicrobial, anti-inflammatory, antihemolytic, and anti-carcinogenic potential were identified. The Abies alba needle extract was more toxic to microbial strains than the eukaryotic cells that provide its active wound healing principles. In this context, developing industrial upscaling strategies is imperative for the long-term success of biorefineries and incorporating them as part of a circular bio-economy. |
