Welcome to the Pacific Ecoinformatics and Computational Ecology Lab. Our "PEaCE" Lab, based in Berkeley, CA, is a non-profit interdisciplinary research institute founded in 2004 to promote awareness of ecological interdependence through research, development and education related to ecoinformatics and computational ecology.

Interested in publications on various topics that lab scientists work on? Check out our Projects page, where you can find sets of pdfs on topics such as informatics; ecological network structure, dynamics, and robustness; human impacts on ecosystems; reviews and commentaries; and field-based research in marine and terrestrial habitats. Check out our Publications page to find the full set of lab scientist references, organized by year.

Interested in food-web data or images? Check out our Webs on the Web project and the "food web gallery" link to the left.

Interested in working with us? Lab scientists are based in different places, and we collaborate with researchers from a wide variety of disciplines. Most of us also advise students and postdocs. Please contact Lab scientists directly about their interests and opportunities for collaboration or mentoring.  For more info about research and education opportunities, click here.

what's happening in the lab


Rich Williams co-authored a letter to Science and an associated article in Biological Conservation on the role of scientific research for assessing the impacts of international trade on CITES (the Convention on International Trade in Endangered Species). The first author is a former post-doc of Rich’s.

Neo Martinez and Jennifer Dunne provided commentary on a 2011 Nature Communications study on “Rescuing ecosystems from extinction cascades through compensatory perturbations” for articles in NatureNews and ScienceNews.

Food security implications of global marine catch losses due to overfishing by Thara Srinivasan and colleagues appeared in the Journal of Bioeconomics on August 17, 2010 (first online). The Pew Environment Group published a research summary called Overfishing trends and the global food crisis, and a press release can be found here. This study and three related ones have been reported in various media outlets, including Reuters, The Vancouver Sun, The Montreal Gazette, and many others. This article was selected as a “must read” paper for Faculty of 1000.

Organismal traits are more important than environment for species interactions in the intertidal zone by Spencer Wood and colleagues appeared in the September 2010 issue of Ecology Letters. This article was selected as a “must read” paper for Faculty of 1000 Biology.

Eric Berlow was named a 2010 TEDGlobal Fellow, and spoke at the associated conference in Oxford in July. Watch his excellent short talk on How complexity leads to simplicity.

Predicting invasion success in complex ecological networks
by Tamara Romanuk and other Lab scientists, and Cascading extinctions and community collapse in model food webs by Jennifer Dunne and Rich Williams, appeared in the June 27, 2009 issue of the Philosophical Transactions of the Royal Society B on "Food-web assembly and collapse: mathematical models and implications for conservation." 

Simple prediction of interaction strengths in complex food webs by Eric Berlow, Uli Brose and other Lab scientists appeared in the Proceedings of the National Academy of Sciences USA on January 6, 2009. A summary can be found here.

Neo Martinez was elected to a three year term (2008-2010) to the Board of Directors of SACNAS, the Society for Advancement of Chicanos and Native Americans in Science. SACNAS is widely recognized as the "premier organization that promotes diversity in science careers."  Its mission is to encourage Chicano/Latino and Native American students to obtain advanced science degrees and to pursue research, teaching, and leadership careers at all levels.

Compilation and network analyses of Cambrian food webs by Jennifer Dunne, Rich Williams, Neo Martinez, and colleagues appeared in the open-access journal PLoS Biology on April 29, 2008 (press release). This study has been reported by Nature, Science, Science Daily, German Public Radio, Folha de S. Paolo, and The New Mexican, and was selected as a "must read" paper for Faculty of 1000 Biology.

The "Goldilocks factor" in food webs, a commentary by Eric Berlow, Uli Brose, and Neo Martinez, appeared in the Proceedings of the National Academy of Sciences USA on March 18, 2008.

The debt of nations and the distribution of ecological impacts from human activities by Thara Srinivasan and colleagues appeared in the Proceedings of the National Academy of Sciences USA on February 5, 2008. This study has been reported by Nature, Science, BioScience, National Public Radio, World Science, United Press International, The Guardian, The Telegraph, and other outlets.

Ilmi Yoon and students developed a Parts, image, and sketch-based 3D modeling method for the study of insects.

Diversity and complexity of ecosystems: exploring balance and imbalance in nature, a video by Neo Martinez, Ilmi Yoon, and others, won second place in the Competition on Visualizing Network Dynamics at NetSci 2007.

Lab research featured in SFI Bulletin article on Risk in financial markets: learning from nature.
Lab research and food-web image featured in PLoS Biology article on Restoring nature's backbone.
Lab research featured in leading conservation biology magazine Conservation in Practice.
Lab icon of ecological complexity chosen as Math Awareness Month poster child.
