Greenhouse in Germany where Exposito-Alonso did research.
April 10, 2020

Palo Alto, CA— Carnegie’s Moises Exposito-Alonso was selected for the Heidelberg Academy of Science’s Karl Freudenberg Prize in recognition of outstanding early career achievements in the natural sciences. The prize comes with a personal 10,000 Euro award.

Representing the German state of Baden-Württemberg, the academy honors several professors under the age of 40 with endowed prizes each year, including six in 2020. All of the recipients will give public presentations of their work, with dates to be announced. An evolutionary geneticist, Exposito-Alonso received his doctorate in 2018 from the Max Planck Institute for Developmental Biology in Tübigen.

Washington, DC— Carnegie evolutionary geneticist Moises Exposito-Alonso was named a member of the 2020 class of Forbes’ 30 Under 30 Europe list in science and healthcare. 

He was recognized for his lab’s pioneering use of genomic techniques to understand how plant species will evolve and keep pace with a changing climate. 

Out of the thousands of nominees, the 30 finalists in each of the 10 categories comprise “the world’s most impactful community of young entrepreneurs and game-changers,” said the publication in announcing his selection.

The Carnegie Institution for Science is consolidating our California research departments into an expanded presence in Pasadena. With this move, we are building on our existing relationship with Caltech, with a goal of broadening our historic collaborations in astronomy and astrophysics and pursuing new opportunities in ecology and plant biology that will support the global fight against climate change.

This plan, which affects our research operations in Pasadena and Palo Alto, reflects Carnegie’s ongoing efforts to extend our leadership in space, Earth, and life sciences and to enhance our ability to explore new frontiers.

In selecting our Pasadena location, we

Palo Alto, CA— Carnegie’s Moises Exposito-Alonso is one of four recipients of the American Society of Naturalists’ Jasper Loftus-Hills Young Investigator Award in recognition of “outstanding and promising work” by individuals who are within three years of completing their Ph.D or in their final year of graduate school.

Exposito-Alonso is an evolutionary geneticist who joined Carnegie last September as a staff associate, a prestigious position designed for early career scientists who are ready to independently deploy creative approaches to challenging research projects.

Revolutionary progress in understanding plant biology is being driven through advances in DNA sequencing technology. Carnegie plant scientists have played a key role in the sequencing and genome annotation efforts of the model plant Arabidopsis thaliana and the soil alga Chlamydomonas reinhardtii. Now that many genomes from algae to mosses and trees are publicly available, this information can be mined using bioinformatics to build models to understand gene function and ultimately for designing plants for a wide spectrum of applications.

Devaki Bhaya wants to understand how environmental stressors, such as light, nutrients, and viral attacks are sensed by and affect photosynthetic microorganisms. She is also interested in understanding the mechanisms behind microorganism movements, and how individuals in groups communicate, evolve, share resources. To these ends, she focuses on one-celled, aquatic cyanobacteria, in the lab with model organisms and with organisms in naturally occurring communities.

 Phototaxis is the ability of organisms to move directionally in response to a light source.  Many cyanobacteria exhibit phototaxis, both towards and away from light. The ability to move into optimal light

Arthur Grossman believes that the future of plant science depends on research that spans ecology, physiology, molecular biology and genomics. As such, work in his lab has been extremely diverse. He identifies new functions associated with photosynthetic processes, the mechanisms of coral bleaching and the impact of temperature and light on the bleaching process.

He also has extensively studied the blue-green algae Chlamydomonas genome and is establishing methods for examining the set of RNA molecules and the function of proteins involved in their photosynthesis and acclimation. He also studies the regulation of sulfur metabolism in green algae and plants.

Evolutionary geneticist Moises Exposito-Alonso joined the Department of Plant Biology as a staff associate in September 2019. He investigates whether and how plants will evolve to keep pace with climate change by conducting large-scale ecological and genome sequencing experiments. He also develops computational methods to derive fundamental principles of evolution, such as how fast natural populations acquire new mutations and how past climates shaped continental-scale biodiversity patterns. His goal is to use these first principles and computational approaches to forecast evolutionary outcomes of populations under climate change to anticipate potential future

Plants are essential to life on Earth and provide us with food, fuel, clothing, and shelter.  Despite all this, we know very little about how they do what they do. Even for the best-studied species, such as Arabidopsis thaliana --a wild mustard studied in the lab--we know about less than 20% of what its genes do and how or why they do it. And understanding this evolution can help develop new crop strains to adapt to climate change.  

Sue Rhee wants to uncover the molecular mechanisms underlying adaptive traits in plants to understand how these traits evolved. A bottleneck has been the limited understanding of the functions of most plant genes. Rhee’s group is
