Sarah Quraishi. Sarah Qureshi, also spelled Quraishi, () is a Pakistani aerospace engineer, jet engine inventor, and hobby pilot. She earned her PhD in Aerospace Propulsion Engineering from Cranfield University. Qureshi is the co-founder and Chief executive officer of Aero Engine Craft.

Early life and education 
Qureshi was born in Islamabad to a family deeply rooted in science. From a young age, she was fascinated by aviation, inspired by her father's work in the industry. She often assisted him with engines and machines, sparking her lifelong interest in engineering.

Quraishi earned her bachelor’s degree in mechanical engineering from the National University of Sciences & Technology (NUST), followed by a master’s degree in aerospace dynamics and a Ph.D. in aerospace propulsion from Cranfield University. After completing her studies at NUST, Qureshi pursued her love for flying, earning a private pilot's license. While at Cranfield, she also trained in flying.

Career 

Qureshi started work in automotive industry of Pakistan. Her research involved design of a trajectory following controller inclusive of stability augmentation altitude control system and outer loop autopilot for unmanned aerial vehicles (UAV). During her Ph.D., Quraishi supervised MSc students in their research projects on jet engine technology.

Quraishi, along with her father, Masood Latif Qureshi, a prominent Physicist and a scientist, set up a company Aero Engine Craft to develop environment-friendly engines for airplanes. Quraishi designed a contrail-free aero-engine with added features of reduced carbon footprint, to counter global warming.

Quraishi's engine design will have a unique pressure-based condensation system, which will cool the water vapors in the aircraft exhaust. This water will remain on the airplane and can be released as rain as required. "We manufactured an engine and then attached the condensation system with it to transform it into a contrail-free aero-engine," Quraishi said. She also said that this will be tested on an aircraft in the next phase.

Quraishi began developing this technology in 2018 as part of her thesis during her PhD studies at Cranfield, and she now continues to collaborate with her professor.

Quraishi revealed that her project has won two international patents and will take at least six years before it is commercially available. She informed that the country’s private sector has taken an environment-friendly initiative for the first time, which will globally highlight Pakistan’s role in the fight against global warming. She is confident that her invention will take the aviation industry by a storm.

Awards 
In 2023, Qureshi won the Study UK Alumni Awards in Pakistan for science and sustainability. In 2014, the President of Pakistan announced that Qureshi will be awarded the Tamgha-i-Imtiaz, the country's fourth-highest civil honour, in recognition of her excellence in the field of science.
