Welcome to the website of the Lazenby Lab, established in August 2019 at the department of Chemistry and Biochemistry at the Florida State University (FSU). We are an electroanalytical chemistry lab at FSU, with research interests in:
- Electrochemical biosensing, including simultaneous multi-analyte detection using aptasenors.
- Electrochemical imaging using scanned probe microscopy, including analytical method development for single cell analysis.
- Electrocatalysis of industrially relevant reactions, such as the investigation of low cost transition metal carbides as electrocatalytic materials for the oxygen evolution reaction.
We are a collaborative and interdisciplinary research group, and currently have a team of PhD students (Ana, Lara, Mikey, Robbie and Airionna), and undergraduate students (Brett, Raphaela and Jahnaya). We are seeking highly motivated graduate students to join us in our research efforts in Fall 2026. To enquire about these positions, or undergraduate research positions, please contact Dr. Lazenby via email about joining the lab.
