Selected Courses

Principles of Chemistry: Principles of Chemistry is a one-semester General Chemistry course required for several majors (Chemistry, Biology, Biochemistry, Neuroscience, Environmental Science) and several programs (pre-health and pre-engineering), and is a prerequisite for all other Chemistry Courses.


Mahesh Dawadi is a Visiting Assistant Professor in the Department of Chemistry at Earlham College, where he has been since this Fall semester 2019. Before joining Earlham, he was a faculty member at the University of Texas Rio Grande Valley and was a post-doctoral researcher associated at the University of Akron in Ohio. He received an M.S. from Tribhuvan University, Kathmandu, Nepal; and a Master’s and Ph.D. in Chemistry from the University of Akron.

My research interests span (1) in investigating the photophysical properties of donor-acceptor organic materials or polymeric materials, potentially for the use in molecular electronics, and specifically for use in low-cost solar cells (2) in studying the energy level patterns and dynamics of isolated gas species relevant to remote atmospheric sensing, environmental protection, hydrocarbon combustion, and petroleum chemistry, and (3) in studying the various properties of molecules/organometallic complexes using quantum mechanical computational programs.

Research Projects

Project 1

Photophysics and Solvent Effect on Tautomerism of Free Base Carrole

We investigate the photophysical and electrochemical properties of corrole molecules and how solvent molecules can influence the ability of this molecule to capture light and mimic photosynthesis. A detailed understanding of the photophysical, electrochemical and spectroelectrochemical properties of these molecules is important in order to use porphyrins and corroles in molecular, electronic and photonic devices.

Project 2

Photophysics, Solvent Effect, and pH effect on Donor-Acceptor Organic Compounds or Polymeric Materials

We investigate the photophysical properties of electron donor-acceptor organic compounds or polymeric materials in the different solvents and in the different and in the different pH values.  We use different techniques like electrochemical, emission and absorption, Atomic Force Microscopy, Transmission Electron Microscopy, and Computational modeling.  Finally, this project focused on the designing of the photovoltaic devices with better efficiency.

Specifically, in this project we would like to demonstrate that absorption and emission spectroscopy and cyclic voltammetry are the key step to investigate the photophysics of the electron-donor and electron-acceptor molecules and complexes and their suitability in the photovoltaic devices and the overall device performance. The specific objective of work under this proposal is to demonstrate the feasibility of the project so that undergraduate students are able to finish this project on time.  This project integrates fundamental research with outreach and communication efforts to engage a diverse group of students in interdisciplinary science, and the community at large, to show how nanotechnology impacts their lives.

Project 3

High-Resolution IR Spectroscopy of Highly Energized Torsional Molecules

This research project focused on the study of the dynamics of the torsional molecules using various spectroscopic techniques. In this project, we will employ spectroscopic tools to investigate the energy level patterns and dynamics of isolated gas species relevant to remote atmospheric sensing, environmental protection, hydrocarbon combustion, and petroleum Chemistry. 

Project 4

Computational Chemistry

This research project involves the study of the various properties of molecules using quantum mechanical computational programs. This project examines the structures and energies of a variety of molecules, from small torsional molecules, organic compounds, and biologically interesting molecules and ions, to polymers.
