Dr. Sara Knezevic


Email: sknezev@purdue.edu
Hometown: Pljevlja, Montenegro
Research Interest: Operando optoelectrochemical studies of local reactivity.
Bio: My research is driven as much by the pursuit of beauty in a well-designed experiment as by a deep scientific curiosity to understand the underlying fundamental phenomena. Much like my experiments, which often involve constant motion and a delicate interplay of light and darkness, I am also always on the move; sometimes impatient, always curious, and excited by new research avenues. When I'm not in the lab, I'm usually sport climbing, bouldering, or dancing tango – activities that suit my love of problem solving, rhythm, and a certain amount of controlled risk.

Azaria Wagner
Email: wagne286@purdue.edu
Hometown: Farmland, Indiana, USA
Research Interest: Applying stochastic electrochemistry to vaccine and nanoparticle analysis.
Bio: In fourth grade, I designed my first real experiment for a science fair. I loved styling my hair with three different gels—Spike-It, Redken Clay Pomade, and Bedhead Manipulator—and wanted to determine which held a style best. I applied each gel, spiked my hair wildly, then did a three-minute headstand, washing and drying between trials. Although not great for blood flow, I loved inventing and executing my own procedure for the first time ever. (Spike-It won, for those who are curious.) That project sparked my lasting passion for science, chemistry, and biology—guiding me toward my current career path.
