Research Interests

Much of the ingenuity of life has revolved around the evolution of metabolic pathways, which has unlocked novel chemistries and expanded the molecular repertoire of nature. In particular, plants have been especially successful through the evolution of many unique and relevant metabolisms, ranging from synthesis of specialized compounds that can be used as pharmaceuticals (e.g., morphine, artemisinin) to broad processes that drive our planet’s elemental cycles (e.g., photosynthesis). As a result, life as we know it could not exist without plants. Given the scale and utility of agriculture, plants offer a unique platform to address many imminent challenges facing society. My research focuses on developing the foundational knowledge needed to innovate, deploy, and engineer new traits in plants using synthetic biology. Beyond biotechnological applications, these approaches can also be utilized to provide more sophisticated tools to improve our basic understanding of plant systems.

Responding to changing light in algae

Photosynthetic organisms depend on light for growth and must maximize its use. However excess light causes cell damage and possible death due to photo-oxidative stress. Thus each cell must respond efficiently to minimize damage, repair and simultaneously maximize the use of light under constantly changing light.

I am interested in understanding the mechanisms and signaling involved in the modulation of photoprotection and repair. I have used genomic, genetic, molecular biology and biochemical techniques to interrogate these processes in Chlamydomonas reinhardtii. The newly available algal genomes such as those of Chromochloris zofingiensis and Nannochloropsis oceanica and their emerging molecular tools will aid in advancing the discovery of genes involved in photoprotection and photosynthesis.

Biomineralization in algae

One can easily appreciate land plants as main players of photosynthesis but in fact nearly half of Earth’s photosynthesis is attributed to the microscopic phytoplankton in the oceans. A dominant group of oceanic algae, diatoms, have a unique type of cell wall that uses one of the most abundant elements, Si. As such, diatoms not only have a large impact on carbon fixation but also on the biogeochemical cycling of Si. I am interested in understanding the molecular process of Si biomineralization in algae by studying the model diatom, Thalassiosira pseudonana and another fresh water stramenopile, Synura petersenii using molecular, genetic, and genomic approaches.

Impact of Environmental Changes on Microbes in Arctic Soils

As the Arctic continues to warm at about twice the rate of the rest of the world, scientists expect its frozen soils—known as permafrost—to thaw, activating microbes capable of decomposing soil and releasing carbons and other nutrients to the atmosphere and water. Berkeley Lab scientists in the Earth and Environmental Systems Area (EESA), led by microbial ecologist Neslihan Taş, set out to learn more about how Arctic soil microbes can contribute to greenhouse gas emissions under a warming climate. Taş’s research team collaborated with Susannah Tringe, Deputy for User Programs at the Joint Genome Institute (JGI), to conduct their study, funded by the Department of Energy’s Office of Biological and Environmental Research (BER). The results were published in Nature Communications.

Biography

Claire Tomlin is a Professor of Electrical Engineering and Computer Sciences at the University of California at Berkeley, where she holds the Charles A. Desoer Chair in Engineering. She held the positions of Assistant, Associate, and Full Professor at Stanford from 1998-2007, and in 2005 joined Berkeley. She received the Erlander Professorship of the Swedish Research Council in 2009, a MacArthur Fellowship in 2006, and the Eckman Award of the American Automatic Control Council in 2003. She works in hybrid systems and control, with applications to air traffic systems, robotics, and biology.

Research Interests

Hybrid Control Systems: These are systems which combine continuous time dynamics with discrete event dynamics. Research involves design, verification using new computational methods for computing reachable sets, and simulation of hybrid systems. We are currently developing the theory and designing models to predict the behavior of complex systems.
This work is supported by NSF, ONR, and AFOSR.

Air Traffic Control Automation: This is joint work with NASA Ames to design models of and control systems for Air Traffic dynamics. This research includes algorithms for automatic resolution of trajectory conflicts between multiple aircraft, as well as novel polynomial time scheduling algorithms.

Algorithms for Decentralized Optimization: In this project, we are designing algorithms with provable convergence properties for decentralized optimization — meaning that several interconnected units act as local decision-makers and optimize local costs, coordinating with each other through constraints. This work is supported by NSF, ONR, and AFOSR.

Human-automation Systems: This research involves analysis of systems for which the control authority is shared between human and automation. We work on the analysis of autopilot systems, driving systems, and robotic systems.

Modeling and Analysis of Biological Cell Networks: In this research project we are building models and analysis tools for helping to understand biological cell networks. Current research includes HER2+ breast cancer, early stage Drosophila development, and planar cell polarity in Drosophila. This is joint work with OHSU, LBNL, UCSF, and Stanford, and is supported by grants from the NCI and NIH.

Unmanned Aerial Vehicle Design and Control: In this project we are building a team of UAVs with the goals of studying formation flying, architectures for distributed control, and methods for reliable control over communication links.
