Publications 

My research primarily focuses on real-world vehicular emissions, driving cycle development, and transportation emission modeling. Our publications investigate emissions from passenger cars and auto-rickshaws, using techniques such as K-means clustering and regression-based modeling to estimate emissions and develop predictive models. Conference contributions extend this work by analyzing the impact of driving styles, developing speed-based emission models, and conducting comparative emission analyses. The findings from the research have been presented at prestigious forums like TRB, WCTR, CTRG, and UMI, reflecting my expertise in low-carbon mobility and sustainable transportation.
