Profile Summary

Hello, I’m Saadia Riaz—a dedicated chemist, researcher, and educator with a Ph.D. in Organic Chemistry from a globally recognized research institute at Karachi University. With one year as a research associate at the same institute, I have contributed to two research articles published in international journals. I also bring three years of experience as a visiting faculty member and an additional year as a teaching associate at respected universities, where I taught chemistry courses. My expertise encompasses organic synthesis, various spectroscopic techniques (including NMR, Mass Spectrometry, UV-Vis, FTIR), and chromatography. I’m well-equipped to assist with assignments and projects across all branches of chemistry. As an experienced academic writer, I have authored numerous research articles, theses, review articles, and a book chapter. Currently, I work as an R&D chemist in a reputable textile industry, focusing on the synthesis and modification of dyes, pigments, and other textile auxiliaries.
