Form Finding Lab – Princeton University

Welcome

By 2050, 70% of the world population will live in cities. Today already 50% live in an urban environment and produce more than 75% of all C0₂ emissions. Finding intelligent and efficient ways to provide for more people with fewer resources will make cities more resilient to manmade and natural disasters and reduce their impact on the environment. Our long-term research goal is to transform the engineering design framework for a future-oriented built urban environment. Our research program addresses the following two core questions: What is the relationship between form and efficiency in civil structures?; and With increasing pressure on the preservation of natural resources, how can design theories and tools match untested sculptural ideas to material-efficient, constructible structures?

Please feel free to get in touch if you are interested in pursuing collaboration.

PRESENTATION: TENSION-ONLY STRUCTURES – FEELING A LITTLE STRETCHED

I am delighted to present our research on tension-only structures to architecture and engineering students in Prof. Ochsendorf's Structures course at MIT. Our advances on the mechanics of suspended rope bridges, inflateable sea barriers and hanging networks will be discussed.

International Day of Women and Girls in Science

According to the UNESCO Institute for Statistics, women make up less than 30% of the world's researchers. Today, Thursday 11th February 2021, is the International Day of Women and Girls in Science. A big shout out to all the women and girls changing the world through science!

HONOR: ASCE SEI FELLOW

It is with great joy that I can inform you that I have been named Fellow of the Structural Engineering Institute (SEI) of ASCE (American Society of Civil Engineering). The SEI Fellow grade distinguishes members of ASCE as leaders and mentors in the profession.

EXHIBITION: Lace -HARNESSING LARGE DEFORMATIONS IN INTERLACED ELASTIC NETWORKS

How can art inspire engineering systems? We have been working with bobbin lace and textile artists to find out. Our work is exhibited at the 2021 Joint Mathematics Meetings, January 6-9 2021.

PRESENTATION: DigitalFUTURES- Shell Structures

To start off the year in a good spirit, I cordially invite you to Virtual Panel and Lecture on Shell Structures on January 16th 2021 (9AM EST, 3PM CET, 10PM China) hosted by Philip Yuan on the DigitalFUTURES platform. Besides myself, Philippe Block (ETHZ) and Chris Williams (University of Bath) will be offering thoughts and design approaches to shells.

And now we welcome the new year, full of things that have never been.
