Sandra Ruiz Perez

Chromatography found Dr. Sandra Ruiz Perez during her doctoral research, where characterizing complex multicomponent mixtures meant living with LC and GC every day. She studied life science at the University of Konstanz (BSc, MSc) as a scholar of the Studienstiftung des deutschen Volkes. Her PhD, completed summa cum laude, was funded by a scholarship from the Research School Chemical Biology. In 2019, she brought that bench perspective to Restek, starting in technical sales, where she supported laboratories across both GC and LC applications. She then moved on to become an LC specialist for clinical, toxicology, and forensic applications, focusing on HPLC/UHPLC method development, column selection, and troubleshooting. Currently, she works as a technical marketing specialist drawing on that combined GC and LC experience. Her peer-reviewed work appears under her birth name, Sandra K. Hess.
