🌱 Early Academic Pursuits

Dr. Atousa Aliahmadi’s academic journey began with a profound curiosity about the natural world and the unseen microbial forces that influence health, agriculture, and biotechnology. She pursued her Master of Science in Microbiology from 1999 to 2002, laying a solid foundation in microbial research techniques and plant-based bioactivity studies. However, it was during her doctoral studies from 2006 to 2011 at the University of Isfahan—one of Iran’s most prestigious institutions—that her academic pursuits took a distinctive direction. Selected through a talent-based acceptance program by Iran’s Ministry of Science, Research and Technology, she joined the Ph.D. program with high academic merit.

Her doctoral thesis, entitled “Investigation of antibacterial and anti-inflammatory effects of plant peptides and extracts,” marked a critical phase in her scientific formation. Throughout her five-year, full-time Ph.D. program, she delved deeply into the bioactive potential of over 20 plant species. By mastering sophisticated analytical techniques such as High-Performance Liquid Chromatography (HPLC), High-Performance Thin Layer Chromatography (HPTLC), two-dimensional electrophoresis (2DE), and various bioassays, she became an expert in isolating and characterizing antimicrobial peptides and phytochemicals. Her research was not only academically rigorous but also practically innovative, yielding peer-reviewed publications and multiple international conference presentations.

🧪 Professional Endeavors

Currently serving as an Associate Professor and Principal Investigator based in Evin, Tehran, Iran, Dr. Aliahmadi holds an academic appointment at Shahid Beheshti University. Her career has blended academic scholarship with applied research. Notably, she was awarded a scholarship and appointed a lecturer at the Medicinal Plants and Drugs Research Institute during her Ph.D., underscoring her early recognition as a promising scientist.

In her role as principal investigator, she has led interdisciplinary projects that integrate microbiology, phytochemistry, and biotechnology. She focuses on harnessing plant and microbial natural products, both primary and secondary metabolites, for applications ranging from food safety to pharmaceuticals. Her research translates laboratory findings into real-world applications such as essential oil-based nano-emulsions for the food and healthcare industries, and plasma, ozone, and microwave decontamination technologies for edible products including spices, vegetables, and saffron.

🧬 Contributions and Research Focus

Dr. Aliahmadi’s research portfolio is impressively broad yet interconnected by a central theme: the discovery and utilization of bioactive natural compounds for health and industrial benefits. She has made significant strides in the areas of antimicrobial and anti-biofilm compound identification, specifically targeting the growing issue of antibiotic resistance. One of her notable scientific pursuits involves elucidating the mechanisms of natural antibacterial agents using advanced analytical tools, particularly in discovering inhibitors of bacterial efflux pumps—key mechanisms by which bacteria develop resistance to antibiotics.

Her interest in nanotechnology is equally groundbreaking. She has developed essential oil-based nano-emulsions that enhance the bioavailability and efficacy of plant compounds, particularly in food preservation and medical applications. Furthermore, she has expanded her work to the field of recombinant protein development, contributing to diagnostics and therapeutic interventions.
