Faculty of Sciences, University of Novi Sad | Serbia
Mrs. Alisa P. Bećin is a committed Research Assistant at the University of Novi Sad, Faculty of Sciences in Serbia. With an academic foundation in molecular biology and a specialized focus on molecular physiology, she is actively engaged in advanced biomedical research, particularly in the area of male reproductive endocrinology. Her work bridges the domains of chronobiology, mitochondrial dynamics, and circadian rhythm regulation, contributing to the understanding of male fertility and reproductive health at the molecular and cellular levels. Alisa’s dedication to experimental rigor and interdisciplinary integration has made her a rising researcher in the European scientific community. She is affiliated with multiple scientific laboratories including the Laboratory for Reproductive Endocrinology and Signaling (LaRES) and the Laboratory for Chronobiology and Aging (ChronAge), where she contributes to both academic research and student mentoring.
Professional Profile
Education
Alisa holds a Bachelor’s and Master’s degree in Biology, specializing in Molecular Biology from the Faculty of Sciences, University of Novi Sad. Her consistent academic progression laid the groundwork for her ongoing doctoral studies, where she is investigating the circadian regulation of mitochondrial function in Leydig cells and spermatozoa. Her PhD research is embedded within a broader molecular physiology program, focused on decoding the influence of biological clocks on cellular energetics and reproductive functions.
Experience
Since 2019, Alisa has been a vital part of the scientific research team at the Faculty of Sciences, initially as a Junior Researcher and subsequently as a Research Assistant. In her role, she actively participates in laboratory-based investigations, coordinates experimental protocols, and supervises student activities. Her teaching involvement spans several critical subjects in physiology and endocrinology, including Chronobiology, Neuroendocrinology, Animal Physiology, and Endocrinology. Alisa’s dual role in research and academia reflects her commitment to both advancing scientific knowledge and nurturing future scholars. Through collaborations with senior researchers and project leaders, she contributes to experimental design, data analysis, and scholarly publications in high-impact journals.
Research Interest
Alisa’s research interests are deeply rooted in the exploration of circadian biology, particularly how internal biological clocks govern male reproductive physiology. Her work investigates molecular clocks within the testes, mitochondrial dynamics in Leydig cells, and their role in steroidogenesis and spermatogenesis. She is especially focused on the interplay between the central clock (suprachiasmatic nucleus) and peripheral clocks, exploring how lifestyle-induced desynchronization affects fertility outcomes. By examining hormonal signaling pathways and mitochondrial bioenergetics, her studies seek to inform chronotherapeutic interventions and address the rising concern of idiopathic infertility in young adult populations. Her scientific approach integrates endocrinology, cell signaling, and chronobiology, establishing her as a multidisciplinary researcher with translational potential.
Research and Publications
Alisa has contributed significantly to peer-reviewed scientific literature, with several publications in indexed journals such as Journal of Comparative Physiology B, BioFactors, European Journal of Cell Biology, Life, and Frontiers in Endocrinology. Her recent works include groundbreaking insights into how constant light and circadian desynchrony disrupt the endocrine and mitochondrial functions of Leydig cells and spermatozoa. These studies advance the understanding of environmental impacts on reproductive health and are influential in the fields of reproductive biology and endocrinology. Her citation index reflects a growing recognition of her work, with 31 citations and an h-index of 3, as recorded in Scopus.
Research Projects
Alisa has been actively involved in both national and provincial research projects. Notably, she is part of an ongoing project funded by the Provincial Secretariat for Higher Education and Scientific Research, which investigates how lifestyle factors influence male fertility. She also contributed to a long-term project supported by the Serbian Ministry of Science, focusing on molecular mechanisms and signal transduction pathways in Leydig cells under homeostatic stress. Her role in these projects includes experimental planning, molecular assays, and interdisciplinary collaboration with endocrinologists and molecular biologists.
Awards and Memberships
Her professional excellence is further recognized through her membership in respected scientific bodies such as the Biochemical Society of Serbia, the Serbian Society for Molecular Biology (MolBioS), and the Society for Research on Biological Rhythms (SRBR). These affiliations underscore her active engagement with the international scientific community and her contribution to ongoing dialogues in reproductive and chronobiological research. She has completed professional certifications, including one in R Programming for Data Analytics in Bioinformatics, reflecting her capability in data-driven biological research and bioinformatics.
