As ALD, Adams oversees the Biosciences Area's three Divisions and one User Facility. He is a senior scientist who has served as Director of the Molecular Biophysics and Integrated Biology (MBIB) Division from 2015-22 and as Vice President for Technology and Director of Structural Biology for the Joint BioEnergy Institute (JBEI) since 2007. He established and heads a multi-institutional program that develops the Phenix software suite used by structural biologists worldwide to solve macromolecular structures. In addition, he has overseen the Biosciences activities at the Advanced Light Source (ALS) since 2011 and has been Laboratory Research Manager for the ENIGMA Science Focus Area since 2009.

As Science Deputy, Christiansen supports the Biosciences ALD in planning and executing long-range strategies to advance the Area’s scientific mission. She has served as Head of the Strategic Programs Development Group (SPDG) since its inception in 2020, leading program development activities for the Area, including building new multi-institutional research programs with other national laboratories. She is also responsible for the Biosciences 10-year Strategic Plan, which describes the Area's research aspirations in energy, environment, health, and tools development for transforming biological research.

Humphreys has worked in the University of California (UC) System for over 20 years gathering a wealth of experience and honing her analytical, communication, planning, and project management skills. Prior to joining the Biosciences Area in 2018, she served as Director of Administration for the Department of Bioengineering at UC Berkeley. She has a strong track record in management, having twice received the Berkeley Staff Assembly Excellence in Management Award.

In addition to leading the BSE Division, Simmons serves as Chief Scientific and Technology Officer and Vice President of the Deconstruction Division at the Joint BioEnergy Institute (JBEI). For the past 15 years, he has been part of the senior management team at Sandia National Laboratories, most recently serving as the Senior Manager of Advanced Biomanufacturing, Biomass Program Manager. His expertise includes biofuels, renewable chemicals, biomanufacturing, abiotic-biotic interfaces, biomass pretreatment, enzyme engineering, biofuel cells, templated nanomaterials, microfluidics, desalination, and biomineralization. Simmons was elected to the National Academy of Inventors in 2024.

Major foci of Tringe's current research efforts are the roles of microbial communities in wetland carbon cycling and the interactions of plants with their associated microbiomes. Tringe earned her bachelor’s degree in physics from Harvard University and her doctorate in biophysics from Stanford University. In her nearly two decades at Berkeley Lab, Tringe previously served in multiple roles at the DOE Joint Genome Institute (JGI), including Deputy of User Programs and head of the Metagenome Program. She is the 2021 recipient of the Ernest Orlando Lawrence Award, one of DOE’s highest honors, and was named a Fellow of the American Association for the Advancement of Science (AAAS) in 2018.

Yano is also a co-principal investigator of the multi-institutional Liquid Sunlight Alliance (LiSA), part of the DOE Fuels from Sunlight Energy Innovation Hub. Prior to assuming the Interim Division Director role in 2021, she served as MBIB Deputy for Science and, before that, she led MBIB’s Bioenergetics Department for five years. She has served as a member of the Lab Staff Committee since 2016 and the DOE Council on Chemical and Biochemical Sciences since 2015. Her research group uses X-ray spectroscopy and crystallography at X-ray free electron lasers and synchrotron facilities to understand biological and inorganic systems under functional conditions.

Mouncey joined Berkeley Lab as Director of JGI in 2017, becoming the fourth director in the User Facility's 20-year history. He has a wealth of managerial experience from almost two decades in the industrial biotechnology private sector, as well as research expertise in secondary metabolites and synthetic biology. Mouncey leads his own research group at JGI focused on secondary metabolites and is also the Deputy Leader of the National Microbiome Data Collaborative. In addition, he served as President of the Society for Industrial Microbiology and Biotechnology for the 2022-23 program year.
