Profile Summary

I am a Ph.D. biophysicist with over 10 years of research experience in the USA, UK and Japan, specializing in single-molecule biophysics, molecular biology, protein biochemistry, and advanced fluorescence microscopy. My expertise focuses on understanding biomolecular interactions, protein–nucleic acid recognition, and conformational dynamics using cutting-edge single-molecule techniques. I obtained my Ph.D. in Biophysics from the University of Illinois at Urbana-Champaign, USA, where I used multi-color single-molecule total internal reflection fluorescence microscopy (TIRFM) to directly investigate the relationship between protein conformational dynamics and DNA repair mechanisms. During my postdoctoral research at Imperial College London, UK, I studied nucleosome remodeling mechanisms using single-molecule FRET (smFRET). As a Research Scientist at Saint Louis University, USA, I applied advanced single-molecule approaches, including correlative optical trapping–fluorescence microscopy and ALEX smFRET, to study DNA repair and homologous recombination proteins. My technical expertise includes: • Single-molecule fluorescence microscopy (TIRFM, smFRET, ALEX-smFRET) • Correlative optical trapping–fluorescence microscopy • Molecular cloning and site-directed mutagenesis • Recombinant protein expression and purification • Protein biochemistry and functional assays • Quantitative analysis of single-molecule and fluorescence data Beyond research, I have a good teaching experience in Biophysics, Molecular Biology, Biochemistry, and Physics. I have taught undergraduate and graduate courses as a lecturer at Cairo University, Egypt, and served as a Teaching Assistant at the University of Illinois at Urbana-Champaign, USA. I can support research and industry projects involving: • Experimental design and optimization • Molecular and biophysical characterization of proteins and nucleic acids • Fluorescence microscopy and imaging strategies • Single-molecule data analysis and interpretation • Scientific consulting, literature review, and technical writing • Training and mentoring in biophysics and molecular biology techniques With international research experience across leading institutions in the USA, UK and Japan, I bring a combination of advanced experimental expertise, scientific problem-solving skills, and strong communication abilities to collaborative research and consulting projects.
