Dr. Haleema received B.Sc. in Electrical Engineering from UET Lahore and M.Sc. in Energy Systems Engineering from Ghulam Ishaq Khan Institute of Engineering Sciences and Technology in 2015 and 2017 respectively. She won the prestigious Fulbright scholarship for Ph.D. in Electrical Engineering at Arizona State University. She is also a recipient of Erasmus Mundus scholarship to carry out master’s research in University of Sannio in Italy. She went to Florida Gulf Coast University on Gobal Ugrad exchange program in the US.

Dr. Haleema carried out Ph.D. research on Electric Vehicle (EV) powertrains and grid-connected photovoltaic (PV) converters. She worked on low-Loss Pulse Width Modulation (PWM) method called 240° clamped PWM (240CPWM) to improve the efficiency and dynamic performance of EV traction inverters and grid connected photovoltaic converters. 240CPWM helps to achieve 85% saving in switching loss in inverter as compared to conventional PWM (CSVPWM) without compromising on Total Harmonic Distortion (THD). Peak Common Mode Voltage (CMV) is reduced by 66.66% and significant reduction in leakage current is achieved with 240CPWM as compared to CSVPWM. Application of 240CPWM is also studied in grid-connected PV converters. Control of 240CPWM with non-unity power factors and under adverse grid conditions is explored in detail. She also worked on a real distribution network of Italy to analyze the effect of high renewable energy penetration in conventional grid during her master’s research.
