Welcome to my personal website! I am a condensed matter physicist with a focus on experimental research in materials characterization, spectroscopy, solid-state physics, nanoscience, and quantum systems. I have a background in data analysis, machine learning, and creating mathematical models to understand real-world data.

My current research focuses on the development of next-generation photovoltaic cells through the investigation of novel materials and structures. Using optical spectroscopy, I study the fundamental properties of these materials and systems in order to understand their potential for high-efficiency photovoltaics. I also collaborate with organizations such as the National Renewable Energy Laboratory, Swift Solar, the Naval Research Laboratories, and NASA to investigate the carrier dynamics and stability of perovskite materials for use in solar cells and space applications.

I have published my research in various academic journals, and I am dedicated to furthering our understanding of these complex materials and systems.

Quantitative Skills

In my research, I have developed a range of skills in data analysis, problem-solving, and programming. I have created GUI for windows OS to facilitate communication between lab equipment and computers and ease data acquisition using LabView. I am proficient in using Mathematica and Python for data analysis and visualization, and have also written neural network machine learning programs in Python using TensorFlow. Thank you for visiting my website, and please don't hesitate to reach out if you have any questions or would like to collaborate
