Ingo Tews - Astrophysics and Cosmology

Chris Fryer

Ingo Tews is a nuclear theorist who tries to understand the properties of various nuclear systems, ranging from atomic nuclei all the way to the dense matter in the core of neutron stars. He received his Ph.D. degree in Physics at the Technical University in Darmstadt, Germany, in 2015, and became a Staff Scientist in the Nuclear Physics, Astrophysics and Cosmology group (T-2) at LANL in 2019. His doctoral thesis was awarded the Dissertation Award of the German Physical Society as well as the Ph.D. prize of the GSI Helmhotz Centre for Heavy Ion Research. His main research interests include nuclear interactions from chiral effective field theory, nuclear many-body forces, uncertainty quantification, quantum many-body methods, and their applications to compute properties of atomic nuclei and dense matter. He is an expert for the equation of state of neutron-star matter and its inference from multi-messenger observations of neutron stars and their mergers, and has published over 40 articles in prestigious journals, including Science and Nature.

Sanna Sevanto - Earth Systems

Sanna Sevanto

Sanna Sevanto is a physicist-turned-plant physiologist with broad expertise in transport phenomena in complex natural systems. She has a master’s degree in Material Science and a PhD in Applied Physics from the University of Helsinki, Finland. Her interests in biomechanics and the environment have led her to apply the knowledge of physics to studying plant physiology and plant responses to environmental stress. Before beginning her career at LANL in 2009, she spent three years studying plants at Harvard University and teaching atmospheric thermodynamics and fluid mechanics at the University of Helsinki. Her research has focused on measurements and modeling of plant-atmosphere interactions, ecosystem energy, water and carbon cycles, plant hydraulics, plant responses to stress, as well as mechanistic understanding of plant structure and function. She has over 70 peer-reviewed publications and has collaborated with researchers from various disciplines ranging from applied and theoretical physics and global-scale vegetation modeling, to cellular and ecosystem-scale biology, ecology, meteorology, atmospheric sciences and material sciences, applying techniques from these fields for understanding plant function and vegetation influence on climate. These techniques include neutron radiography of water flow in plants and plant-root systems, soft-tissue x-ray tomography for studying plant anatomy, ultra-low field NMR for measuring plant drought responses, and linear displacement transducers for measuring pressure changes in plant tissues.


Gian Luca Delzanno - Heliophysics


Gian Luca Delzanno is a Staff Member with the T-5 Applied Mathematics and Plasma Physics Group, Los Alamos National Laboratory, since 2007. His main research activities are theoretical and computational studies of plasma and space physics problems. His research interests include the development of novel numerical methods for multiscale plasma-physics modeling, spacecraft-plasma interaction, radiation belt physics and radiation belt remediation, and the development of new space mission concepts. Some of his research highlights include the 2017 R&D100 award for the SHIELDS framework for space weather modeling, the development of a new spacecraft charging mitigation scheme to enable the operation of high-power electron beams for space applications (which led to the ongoing NASA B-SPICE rocket experiment where Delzanno is the science PI) and the development of the IMPPACT mission concept to study the low-energy populations of the Earth's magnetosphere. Dr. Delzanno was a Post-Doctoral Associate at the Politecnico di Torino from 2003 to 2004, and a Post-Doctoral Associate with the T-15 Plasma Theory Group at the Los Alamos National Laboratory from 2005 to 2006. He received the M.Sc. degree in Nuclear Engineering and the Ph.D. degree in Plasma Physics from Politecnico di Torino, Torino, Italy, in 1999 and 2003, respectively.

Dr. Lisa Danielson - Director

Lisa Danielson has a broad scientific background spanning astrophysics, meteoritics, granitoid petrology, geochemistry, and experimental petrology, laying the foundation for understanding and exploring the solar system. Her professional career started in Houston with a fellowship at NASA Johnson Space Center, where she collaborated in building the high pressure experimental petrology lab that she would later manage, while continuing and expanding research in terrestrial planetary interiors. She's spent the last 10 years working at NASA for Jacobs on the JSC Engineering, Technology, and Science (JETS) contract, growing a career and research program in Sample Science through rapid expansion of facility capabilities and addition of expert personnel.

As Manager of Basic and Applied Research for the JETS contract at NASA JSC, she was appointed a Jacobs Ambassador and is a recent graduate of the Jacobs Leadership Development Program.  During this year-long intensive, she took the opportunity to improve her business acumen related to contract opportunities, management and implementation, completing a sabbatical with Business Development and Sales.

Finding a gap in available student and early career leadership and learning opportunities at JSC, she started a Career Development Seminar Series and founded a grassroots women’s career and outreach organization called Supporting Women at NASA (SWAN).  She’s engaged with university partnerships through implementing formal contract mechanisms, as well as service, activities key for successful recruitment for internships and new positions.  In 2017 she was honored with the UNLV Graduate College Alumna of the Year award, in recognition of leaders who have a positive impact in the world.

Dr. Jeanne Fair - Biological Systems

Jeanne-Fair.jpgJeanne Fair is a scientist in Biosecurity and Public Health Group with a focus in epidemiology and animal disease ecology.In 2009, Fair was a lead analyst for the Department of Homeland Security's modeling of the H1N1 influenza pandemic our Nation's Critical Infrastructure. From 2013-2016 she was on assignment as a Science Program Manager with the Defense Threat Reduction Agency's Biological Threat Reduction Program working with Central Asia and the Middle East.

Dr. Fair's research interest is to support biosurveillance and zoonotic infectious disease detection capabilities in wildlife, animals, and humans. This includes the impacts of environmental stress and change on infectious diseases and vector range movement. In 2011, she was the Editor-in-Chief of the Guidelines for the Use of Wild Birds in Research for the United States and served for 10 years as Chair of the Los Alamos Institutional Animal and Use Committee (IACUC). She has experience in the development of wild and domestic bird immunological techniques for investigating immunocompetence and ecological physiology in birds.
