Research Interests

My long-term research goals are to understand how photosynthetic energy conversion works, how it is regulated, and how it might be improved to help meet the world’s needs for food and fuel. We use a wide array of experimental organisms and interdisciplinary approaches to investigate fundamental questions about assembly, regulation, and dynamics of photosynthesis. Current lab members study the biosynthesis and function of photosynthetic pigments, assembly and repair of photosynthetic reaction centers, structure and dynamics of the photosynthetic membrane, mechanisms involved in sensing excess light, singlet oxygen signaling, transcriptional regulation of photosynthesis and photoprotection by light and carbon, and regulation of photosynthetic light harvesting in saturating light. By comparing how photosynthesis works in diverse organisms, we hope to uncover general design principles of natural photosynthesis as well as unique adaptations to different environments.

Bioscientists to Receive DOE Funding for Biomanufacturing and Microbiome Research

September 30, 2022

Biosciences researchers are among the recipients of four new DOE awards. Two awards will focus on reducing carbon emissions while producing bioenergy. The other two are aimed at understanding the role of microbiomes in the biogeochemical cycling of elements like carbon.

Biosciences Area Scientists Talk Diatoms in Genome Insider Podcast

March 18, 2021

In the latest episode of JGI’s monthly podcast, Genome Insider, Alison Takemura interviews Setsuko Wakao and Kris Niyogi, biologists at UC Berkeley and in Berkeley Lab’s Molecular Biophysics and Integrated Bioimaging (MBIB) Division. In this 20-minute episode, they discuss their research on a tiny group of algae with insanely gorgeous exterior shells.

A Molecular Switch for Photosynthesis and Lipid Accumulation

October 1, 2019

Using a forward genetics approach, a team of Biosciences researchers revealed that the enzyme hexokinase (HXK1), which is involved in sugar metabolism in organisms ranging from bacteria to plants to humans, is necessary for the regulation of photosynthesis and metabolism in the green alga Chromochloris zofngiensis. Kris Niyogi, a faculty scientist in Molecular Biophysics and Integrated Bioimaging (MBIB), was senior author on the paper, published in Nature Communications Biology.
