About Me

Nakul N. Karle, Ph.D.
Assistant Research Scientist and Adjunct Lecturer

Department of Earth, Environment and Equity
Howard University, Washington, D.C.

​

I am currently an Assistant Research Scientist and Adjunct Lecturer at Howard University in Washington, D.C., with a focus on advancing environmental sciences through innovative research and teaching. My academic journey began in Mumbai, India, where I earned both my Bachelor’s and Master’s degrees in Physics from the University of Mumbai. Pursuing further expertise, I moved to the United States to obtain a Master’s degree in Computational Sciences and a Ph.D. in Environmental Sciences and Engineering from the University of Texas at El Paso.

Research

My research is primarily focused on atmospheric sciences, with a particular emphasis on the dynamics of the planetary boundary layer (PBL) and turbulence. The PBL, as the lowest part of the atmosphere, critically influences weather patterns, climate processes, and pollution transport. Through advanced remote sensing instrumentation—including Ceilometer, LIDAR, and RADAR—I conduct high-resolution, real-time analyses of the PBL’s vertical structure and dynamics. These instruments enable precise observations of parameters such as aerosol backscatter coefficients, temperature profiles, water vapor mixing ratios, and vertical wind profiles, significantly enhancing our understanding of atmospheric processes and the accuracy of predictive climate and air quality models.

​

In addition, my current research focuses on the statistical analysis of higher-order moments within the turbulent convective boundary layer (CBL), a complex yet vital area for comprehending atmospheric turbulence. By analyzing skewness and kurtosis within turbulent flows, I aim to deepen insights into the energy distribution and predict extreme events within the PBL. The turbulent nature of the CBL, driven by thermal convection, presents both challenges and unique opportunities for advanced statistical exploration. This research not only contributes to fundamental knowledge in atmospheric science but also holds practical implications for improving weather forecasting, enhancing aviation safety, and advancing climate modeling.

I am also interested in advancing our understanding of air quality dynamics, with a particular focus on ozone and PM2.5 speciation. My research investigates the intricate relationship between atmospheric composition and climate change, working to unravel the complexities influencing air quality across the United States. Leveraging data from EPA ground measurements, I conduct detailed analyses aimed at illuminating shifts in environmental health, with the goal of informing effective strategies and policies to mitigate the impacts of climate change on our communities. This research is part of a broader commitment to fostering a cleaner, healthier future for all.
