In a letter from the Department Chair, Dr. Keith Julien expressed that "The SIAM Activity Group on Nonlinear Waves and Coherent Structures (SIAG/NWCS) awards the T. Brooke Benjamin Prize every two years to one mid-career established researcher for recent outstanding work on a topic in nonlinear waves, as evidenced by a body of work with at least one significant publication in English in a peer-reviewed journal or conference proceedings within the four calendar years preceding the award year. The prize is awarded to a researcher who has been in the profession at least 10 years and no more than 20 years preceding the award date. Candidates who have not worked continuously in the field are also eligible if they are at an equivalent stage in their career. The candidate’s work must contain a significant contribution to the field of nonlinear waves, broadly interpreted in the spirit of the SIAG/NWCS conferences."

The Department Chair continued on to provide the details of the announcement that Dr. Hoefer received:

"The selection committee wishes to recognize you for your 'significant contributions to the understanding of dispersive shock waves in hydrodynamics and other physical systems,' as evidenced in your paper, ."

The Department congratulates Dr. Hoefer on this well-deserved accolade.

Dr. Ezio Iacocca joined the lab in January 2015 as a Swedish International Postdoctoral Fellow.  He mentored graduate and undergraduate students and made many contributions to the success of the lab.  His research on the dynamics of magnetic materials has appeared in high profile publications such as Science and Nature Communications.  Dr. Iacocca helped bridge the lab's fluid dynamics research into a hydrodynamic description of magnetization dynamics, which provides a new perspective on spin dynamics.  Dr. Iacocca is leaving the lab in August 2019 to pursue a faculty career in the University of Northumbria's Mathematics, Physics and Electrical Engineering Department as a Senior Lecturer.  Congratulations Ezio!  We wish you abiding success.

Lab member Mingyu Hu will visit the National Institute of Standards and Technology (NIST) in Gaithersburg, MD for the summer of 2019 to intern with Dr. Mike Donahue.  Mingyu aims to develop micromagnetic software for antiferromagnetic materials that is comparable to .  As noted on the  website:

The National Science Foundation (NSF) Division of Mathematical Sciences (DMS) aims to provide opportunities to enrich the training of graduate students in the Mathematical Sciences through the provision of an NSF Mathematical Sciences Graduate Internship Program. This program will provide an opportunity for mathematical sciences doctoral students to participate in internships at federal national laboratories, industry and other approved facilities. Participation in an internship will provide first-hand experience of the use of mathematics in a nonacademic setting. The internships are aimed at students who are interested in understanding the application of advanced mathematical and statistical techniques to "real world" problems, regardless of whether the student plans to pursue an academic or nonacademic career.

This is a competitively funded internship program.  Congratulations Mingyu!

Adding to his haul of awards and accolades, Dispersive Hydrodynamics Lab (DHL) member and Applied Mathematics/Engineering Physics double major Max Ruth received two additional awards:  the University of Colorado, Boulder’s Outstanding Graduate for Research Award and the National Science Foundation’s prestigious Graduate Research Fellowship.  Max, nominated for the Outstanding Graduate for Research Award by the Department of Applied Mathematics for his research on nonlinear dynamics in magnetic materials while a DHL member, was chosen over nominees from every other College of Engineering department.  The award will be officially announced at University commencement on May 10, 2018.

Following a national competition of more than 12,000 applicants from every corner of the U.S., Max was chosen as one of 2000 awardees for NSF’s competitive Graduate Research Fellowship (GRFP).  As , “the program recruits high-potential, early-career scientists and engineers and supports their graduate research training in science, technology, engineering and mathematics (STEM) fields.”  The GRFP provides three years of financial support to attend a graduate school of the awardees choosing.  Max will be pursuing a PhD in applied mathematics at Cornell University in Ithaca, NY starting this fall.  Congratulations Max!  May your professional success continue.

The Dispersive Hydrodynamics Laboratory is pleased to announce its second experimental paper, published in Physical Review Letters. The paper showcases the novel hydrodynamic interaction between a localized solitary wave with a larger hydrodynamic structure such as rarefaction waves or dispersive shock waves, the latter also  previously published in Physical Review Letters. See the news article.  Both solitary wave transmission through and trapping in the large hydrodynamic wave are theoretically determined and validated by experiments done in the laboratory on the viscous conduit system. Such phenomena can occur in other physical systems such as geophysical fluids (ocean and atmospheric waves), superfluids (Bose-Einstein condensates), and intense light propagation (nonlinear optics).  Therefore, this theory could have a major impact on our understanding of a variety of other physical systems.

The theoretical work was done jointly by Mark Hoefer and Michelle Maiden of CU Boulder's Dispersive Hydrodynamics Lab in collaboration with Gennady El of the University of Loughborough.  The experimental work was done by Lab members Dalton Anderson and Nevil Franco under the supervision of Michelle Maiden.
