Research Interests
Analytical Chemistry-Electrochemistry: Chemical Sensors and Biosensors
-Uses of Immobilized Enzymes

Current research in materials science focuses in the development of new materials, the combination of materials with known physical and chemical properties to create materials with new properties, new processing methods to form nanostructured films and their applications in catalysis, sensing devices and electronics, among others. Our research explores the synthesis of new electrocatalysts, the development of novel ways to imprint nanostructures on surfaces, and the application of these surfaces in electrocatalysis, sensor arrays and smart devices.
