I teach undergraduate and graduate chemistry courses and lead a research group that work on measurement science at the single entity level.
Research Interests
Imaging electrochemical reactions and biological phenomena at the nanoscale and single entity level can provide rich details on:
- heterogeneity in the system and
- enhanced mechanistic insights that are not possible with traditional electro- and bio-analytical tools
The Sundaresan Lab vision is to use and develop high-throughput multimodal imaging techniques such as optical, electrochemical, and electron imaging to understand electrochemical and biological phenomena at the single entity level and utilize the obtained insights to design better performing catalytic and biological systems at the ensemble level. Accordingly, the group will focus on interfacing novel high-resolution optical imaging techniques, including super-resolution imaging, with electrochemical techniques that can address fundamental scientific questions in the fields of electrocatalysis, materials science, and biology. Additionally, the developed methodology can be used to design ultra-sensitive chemical and biosensors.
Biography
Vignesh Sundaresan is an Assistant Professor of Chemistry and Biochemistry at the University of Mississippi. He obtained his Ph.D. in 2018 from Temple University under the supervision of Prof. Katherine A. Willets. He then worked as a postdoctoral associate with Prof. Paul W. Bohn at the University of Notre Dame from 2019 to 2021. He served as an Assistant Research Professor at the University of Notre Dame between 2021 and 2022. His laboratory currently focuses on employing correlated opto-electrochemical techniques to study single entities and electrochemical phenomena at the nanoscale. He has received the NSF EPSCoR Research Fellows Award.
