Fall 2025 Newsletter
 
 
Update from our Chair
 
 
Department Chair Sarah Billington
 
 
 
Dear Stanford Civil & Environmental Engineering Alumni, Friends, and Community,

Our fall quarter is now well underway. We welcomed over 200 new graduate students and newly declared undergraduates into our department, bringing our total student community to over 540 students.

In addition to the news below, I am pleased to announce several professional and personal milestones. Professor Hae Young Noh was recently promoted to full Professor, Professor Sarah Fletcher was reappointed to Assistant Professor, and Professor Mike Lepech and his wife Joanne welcomed their first child!
 

This fall will be Professor Anne Kiremidjian’s last quarter on the faculty as she will be retiring from Stanford on January 1, 2026. Professor Kiremidjian has been at Stanford for over 50 years and spent 47 years on our faculty. She was the first woman to be appointed as an Assistant Professor in Stanford’s School of Engineering, to receive tenure, and go on to future promotions. She has been a pioneer in so many ways, and we wish her all the very best in her retirement.

It is with deep sadness that I must also share the news that our beloved colleague, Professor Dick Luthy passed away unexpectedly on October 6th. His Stanford obituary is linked below. Professor Luthy was an extraordinary member of the Civil & Environmental Engineering community for decades. His academic achievements and contributions beyond Stanford were immense. He was kind, brilliant, and dedicated to his students, colleagues, and most of all to his own family. We are heartbroken by this loss. A memorial in 2026 will be announced on our department webpage and through a future department newsletter.


I encourage you to stay connected with us throughout the year, including through the School of Engineering’s ongoing 100th anniversary celebrations. We truly appreciate your support and your ongoing participation in the Stanford Civil & Environmental Engineering (CEE) community.

With gratitude,

Sarah Billington

Most U.S. households can save money and weather blackouts with solar plus storage


A new study, co-authored by Ram Rajagopal, associate professor of CEE, and Arun Majumdar, dean of the Stanford Doerr School of Sustainability, indicates that most U.S. households could reduce their electricity costs and comfortably endure power outages by installing rooftop solar panels and battery packs.

Wastewater is 99.9% water, but the last 0.1% contains valuable energy, materials, nutrients, and information. The most recent issue of Stanford Magazine delves into the multidisciplinary research on wastewater led by several CEE faculty, including Richard Luthy, William Mitch, Alexandria Boehm, Meagan Mauter, and William Tarpeh, as well as Professor Emeritus Craig Criddle.

The Woods Institute for the Environment announced the 2025 Environmental Venture Projects and Realizing Environmental Innovation Program awards, which will fund proposals from several CEE faculty members.


The Stanford Doerr School of Sustainability’s Accelerator program announced its first grants for Water research. The focus of this effort is to ensure availability, resiliency, sustainable management, and equitable access to clean water for all people, agriculture, industry, and ecosystems while minimizing greenhouse gas emissions by 2050. CEE faculty members will lead several of the projects.


A research team including faculty and students from the Stanford Doerr School of Sustainability and CEE has created a new model that projects emissions, society-wide economic costs, and consumption of energy resources for California to reach net-zero emissions by 2045. CEE PhD student Joshua Neutel is the study’s lead author.


CEE Professor Mark Jacobson designed and built his own home, described as a “zero net energy house,” which he believes is a blueprint for a more sustainable future. It is all-electric with no gas on the property, it generates as much energy as it consumes, and all the energy generated is clean and renewable, with no polluting fossil fuels.



A team of Stanford researchers, led by William Tarpeh, assistant professor of chemical engineering and, by courtesy, of CEE, has developed an innovative new system that harnesses urine to generate valuable fertilizer, offering solutions for sanitation and energy in resource-limited regions.



Earth System Science Professor Leif Thomas leads numerous researchers investigating the journey of microplastics in our environment and their effects on human health, while developing practical solutions to mitigate their impact. CEE Professors William Mitch and Richard Luthy contribute to an FAQ section following the linked article.
