2015-2016 LANSCE Rosen Scholar

Markus Roth

Markus RothDr. Markus Roth is a Full Professor at the University of Technology in Darmstadt, Germany at the Institute for Nuclear Physics, where he has been since 2003. He leads a research group that is also associated with the German National Laboratory “Gesellschaft für Schwerionenforschung (GSI),” with the main focus on dense plasma physics, advanced diagnostic methods, and particle acceleration by ultra-intense lasers. He has also led international research teams on the topic of ion acceleration. He received his Diploma in 1994 and PhD in 1997.

Roth has served his community as a reviewer for funding agencies (NSF, DOE, NNSA, CCLRC, IUF and others), in addition to refereeing for the standard scientific journals. He serves as the spokesperson of various collaborations within the LIGHT collaboration (Laser Ion Acceleration Handling and Transport), focused on the combination of a laser ion driver and a conventional accelerator. He also serves as an international lecturer on plasma and ion beam physics, and is the spokesperson for French-German and a US-German bilateral collaborations on dense plasma physics.

Roth became an APS Fellow in 2013, and received an Defense Physics Award of Excellence from DOE in 2014. His work is especially recognized in inertial confinement fusion (ICF), fast ignition, and research in novel ion acceleration concepts using ultra-intense lasers and their applications.

He was honored by the 2012 Rosen Scholar Award from the Los Alamos National Laboratory, where he lead an international team to establish a laser driven neutron source at the LANL TRIDENT laser facility.

2014-2015 LANSCE Rosen Scholar

Edwin Fohtung

Edwin FohtungDr. Edwin Fohtung was named the 2015 Rosen Scholar at the Los Alamos Neutron Science Center (LANSCE) of Los Alamos National Laboratory (LANL) and is the current LANSCE Professor in conjunction with the Department of Physics at New Mexico State University.

A materials physicist, Edwin obtained his PhD from the University of Freiburg in Germany and performed research at ANKA Synchrotron Light Source Facility at the Karlsruhe Institute of Technology (KIT) in Germany. During this time, he became fascinated with the use of neutrons and (in)coherent photons for the study a wide range of condensed and soft matter systems.

Edwin’s current research explores (via experimental and numerical modeling) the use of neutron and coherent scattering techniques, optical (laser-based) pump-probe experimental techniques, pulsed electric and magnetic fields to probe a variety of emergent soft and condensed matter systems. He currently focuses on multiferroics, magnetoelectric, electronic, straintronics, and magnetic phases arising due to competing and/or coupled charge, spin, orbital ordering and lattice interactions.

In addition to his research activities, Edwin provides scientific consultation for the future LANL signature facility: Matter Radiation Interaction in Extremes (MaRIE) project. He is a guest editor of the Journal of Optics special issue on “Coherent Diffractive Imaging” and serves as a member on the ORNL Neutron Sciences -Science Review Committee. Edwin is also the recipient of a Department of Defense-Air Force Office of Scientific Research and Los Alamos National Security/Department of Energy awards.

2013-2014 LANSCE Rosen Scholars

Devinder Sivia

Devinder SiviaDr. Sivia is the Stipendary Lecturer in Mathematics for the Sciences at St. John’s College, Oxford. An accomplished lecturer and author, Devinder’s work on Bayesian methods of data analysis has been published as tutorial volumes in the Oxford Chemistry Primers series, in two slim tutorial volumes, on the "Foundations of Science Mathematics" (1999, OUP). As a lecturer at St. John’s he has taught "Maths for Natural Sciences" to Chemistry and Physics undergraduates for a number of years.

Devinder’s research revolves around the application of Bayesian probability theory to all sorts of data analysis problems, mainly in the physical sciences, and his work has been published in a tutorial book: Data Analysis - a Bayesian tutorial (1996, Second Edition 2006, OUP).

Paul Koehler

Dr. Paul Koehler has performed and led ground breaking research at Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (ORNL). Koehler is currently a guest researcher collaborating in nuclear physics at the University of Oslo in Norway.

While at LANL and ORNL, Paul received numerous industry awards, the most notable of which are a Publication of the Year Award from ORNL and a Nova Award from Lockheed Martin. He has published 95 peer-reviewed papers and over 110 additional international conference articles and has spoken at nearly 50 invited engagements at international meetings.

Koehler is also very active in the community as a mentor and coach. A common thread of all this research, in addition to providing data of importance to basic and applied physics, is experiments aimed at testing and improving nuclear models.

2012-2013 LANSCE Rosen Scholars

Richard Casten

Richard CastenProfessor Casten has many accomplishments and awards including Fellowships in the American Physical Society and the American Association for the Advancement of Science. He was recently awarded the prestigious Tom W. Bonner prize in Nuclear Physics and received the APS Division of Nuclear Physics Mentoring Award.

Professor Casten is very active in the nuclear physics community. He is the present Chair of the FRIB Science Advisory Committee and the past Chair of the Nuclear Science Advisory Committee (NSAC). He has served on all four Long Range Plan Panels since 1989 (1989, 1995, 2001,2007). He was Director of the Wright Nuclear Structure Laboratory from 1995-2008.

Dr. Casten will work at LANSCE to develop new research ideas and possible directions for basic research in nuclear structure. Specific areas of interest include exotic nuclei, the mechanisms for the emergence of collectivity in nuclei, the evolution of shell structure, the stability of the heaviest nuclei, recognizing and interpreting the simple and regular patterns that complex nuclei exhibit, order and chaos in nuclei, the relationship between mass (binding) and structure, and new signatures of structure and its changes with N and Z.

Markus Roth

Markus RothProfessor Markus Roth is a distinguished professor of physics in the Institut für Kernphysik, Technische Universität, Darmstadt. His current research is in the area of neutron production following high- power laser interactions with materials. This emerging field brings together the disciplines of nuclear physics, material science, plasma physics and high- power lasers.

Roth's research goal is to ultimately produce neutrons over a broad energy range using pulsed lasers. Such a source promises to be very compact and cost effective compared to existing neutron sources. If successful, such laser-based neutron sources could be used in a wide range of applications ranging from basic nuclear physics research to industrial applications.

Dr. Roth will work with LANSCE and Physics Division to research novel, compact, high-brightness sources of neutrons using ultra intense lasers.
