Postdoctoral Scholars

May 2021 - present

Padmanabh Joshi (padmanabh.joshi [at]
Post Graduate Diploma in Patent Law, 2020
Ph.D. University of Cincinnati, 2015

B.Tech. Institute of Chemical Technology, 2010

Dr. Joshi was born and brought up in the state of Maharashta, India and attended the Institute of Chemical Technology (University of Mumbai) where he completed his B.Tech. in surface coating and polymer science technology. Following graduation, he joined the lab of Prof. Peng Zhang at the University of Cincinnati for graduate studies, where he developed optically-active nanomaterials for versatile applications. In 2015, he completed his Ph.D. in analytical/physical chemistry and moved to Temple University to do postdoctoral research in the lab of Prof. Katherine Willets. There his research was focused on developing optical readouts to report on electrochemical events at the nanoscale. Dr. Joshi worked as an intellectual property rights professional (IPR) in India from 2019 to the end of 2020 before joining the Wilson Lab as a postdoctoral research associate. His research is focused on revealing intermediates in electrochemical transformations using spectroelectrochemical techniques.

Graduate Students

Md Al Amin (md.alamin [at]
M.S. North Carolina A&T State University, 2020
M.S. Shahjalal University of Science and Technology, 2011
B.S. Shahjalal University of Science and Technology, 2009

I completed my B.S. (2009) and M.S. (2011) in chemistry from the Shahjalal University of Science and Technology in Sylhet, Bangladesh. I worked as a Quality Control Chemist for three more years in the pharmaceutical industry. I also worked as a Lecturer in Chemistry at a community college. I moved to North Carolina, USA, to pursue my M.S. in Nanoengineering from North Carolina Agricultural and Technical State University (2020). During my free time, I like to read and listen to music. My research is focused on catalysis using plasmonic nanostructures and electrochemistry.

Nawaraj Karki (nawaraj.karki [at]
M.S. Middle Tennessee State University, 2020
M.S. Birendra Multiple Campus, Tribhuvan University, 2015
B.S. Tri-Chandra Multiple Campus, Tribhuvan University, 2013

I completed my M.S. in Chemistry in 2015 from Tribhuvan University. I moved to the United States in 2019 to pursue a M.S. degree from Middle Tennessee State University. At MTSU, I worked on developing biosensors using silicon nanowires. My thesis research was based on electrochemical detection of dopamine with p-doped silicon nanowires. I completed my M.S. in 2020 and am now pursuing a Ph.D. in chemistry from the University of Louisville. My research is focused on mass transport effects in electrocatalysis.

Johann Hemmer (johann.hemmer [at]
M.S. Univali, 2023
B.S.E. Univali, 2019

Johann Hemmer lived most of his life in the states of Paraná and Santa Catarina in Southern Brazil, where he received his BSE in Chemical Engineering from Univali (2019), working under Dr. Gizelle Almerindo on the heterogeneous catalytic deactivation of chemical weapons. After graduating, he worked for 3 years in Univali’s Central Analytical Lab overseeing the Chromatography Sector. Concomitantly, he pursued his MS in Pharmaceutical Sciences under Dr. Clovis Rodrigues in the same institution with an emphasis in Analytical and Environmental Chemistry. In Fall 2022, Hemmer joined the University of Louisville’s PhD program, where he is a member of the Wilson Lab. His research aims to reduce ensemble averaging in electrocatalysis measurements to provide mechanistic understanding at the single entity level. 

Undergraduate Students

Jaley Adkins (jaley.adkins [at]

I am currently an undergraduate public health major in the School of Public Health & Information Sciences. On campus I am involved in Delight Ministries, Alpha Omicron Pi, and serve as a staff member for the university’s first undergraduate research journal, The Cardinal Edge. My research focuses on synthesizing gold and silver nanoparticles using plant-based extract and exploring the use of these particles for medical purposes. I would like to continue in the research field by pursuing a doctorate in pharmaceutical sciences and focus on nanoparticle driven delivery of medications.
