New combustion models improve efficiency and accuracy

Researchers at Princeton University have developed a new model that will allow engineers to accurately predict the characteristics of combustion processes with far less computing power than previously needed. The new model breaks a long-standing trade-off between models that are efficient but narrowly useful and models that are more general but computationally expensive.

Dean Andrea Goldsmith welcomes you to Princeton Engineering

In this video, Dean Andrea Goldsmith provides an overview of what makes Princeton Engineering special.

Speaking creates droplets linked to disease transmission

For the first time, researchers have directly visualized how speaking produces and expels droplets of saliva into the air. These droplets can be inhaled by other people and are a primary way that respiratory infections like COVID-19 spread from person to person.

Conversation quickly spreads droplets inside buildings

With implications for the transmission of diseases like COVID-19, researchers have found that ordinary conversation creates a conical ‘jet-like’ airflow that quickly carries a spray of tiny droplets from a speaker’s mouth across meters of an interior space.

Researchers use electric fields to herd cells like flocks of sheep

Princeton researchers have created a device that can herd groups of cells like sheep, precisely directing the cells’ movements by manipulating electric fields to mimic those found in the body during healing. The technique opens new possibilities for tissue engineering, including approaches to promote wound healing, repair blood vessels or sculpt tissues.

Funding the next big idea: New projects receive Dean for Research Innovation awards

Several projects that push the boundaries of knowledge and have high potential for impact have been awarded support through Princeton’s Dean for Research Innovation Fund.

Junior faculty awards recognize outstanding teaching and research

The School of Engineering and Applied Science is honoring six assistant professors for early-career excellence in research and teaching. This year’s junior faculty award recipients will each receive $50,000 to support their research.

Graduates recognized for innovation, service and perseverance

The School of Engineering and Applied Science virtually celebrated its 2020 Class Day ceremony, with interim Dean H. Vincent Poor commending graduates for courage and determination during a difficult time.

NSF RAPID grant backs study on talking and COVID transmission

A National Science Foundation grant will support Princeton researchers studying how COVID-19 may be spread by people without symptoms through everyday social interactions involving breathing and speaking.

American Academy of Arts and Sciences elects three Princeton engineers

Three professors at the School of Engineering and Applied Science have been named members of the American Academy of Arts and Sciences. The honorees, Ruby Lee, Margaret Martonosi and Alexander Smits, are among 12 Princeton faculty members elected to the academy this year.
