Accelerated
Merit Advancement to Professor, Step III
I have received a three-year accelerated merit advancement from Professor,
Step I, to Professor, Step III, which will take effect July 1, 2016.
Accelerations are typically awarded on the basis of unusual achievement
and exceptional promise of continued growth. During the three merit
reviews I have undergone since arriving at UCSD, I have received a
total of two accelerations, and one half-step bonus.
Kavli Fellow, National Academy of
Sciences I have been invited in participate in the German-American Kavli
Frontiers
of Science symposium, which is jointly organized by the Alexander von
Humboldt Foundation and the National Academy of Sciences.
The symposium bring together outstanding young scientists
to discuss exciting advances and opportunities in a broad range of
disciplines. A committee of NAS members selects the participants from
among young researchers who have already made recognized contributions to
science, including recipients of major fellowships and awards. [ Poster ]
In Memory of Jerrold E. Marsden (1942-2010)
On September 21, 2010, my dear advisor, mentor, role model, collaborator,
colleague, and friend, Jerry
Marsden, lost his battle with cancer. He will
be missed and remembered always.

Research Vignette on Streaming Video
Prior to joining UCSD, I was an assistant professor at Purdue
University, and the department of mathematics there commissioned a short
video vignette where I describe my research in a broadly accessible
fashion. This is available as a streaming video.
Academic
and Industrial, Science and Engineering Collaborations and Consulting
Opportunities Welcomed
I am constantly on the lookout for interesting and challenging
collaborations with scientists and engineers from academia or industry. I
am also available as a consultant for modeling, simulating, controlling,
and quantifying uncertainty for systems that evolve on complicated nonlinear
configuration spaces. Have a look at my YouTube channel for
examples
of applications, and if you would like to learn more about the role that
geometric numerical methods might play in your application, please feel
free to contact me.
Much of my theoretical work is motivated by specific applications.
To paraphrase William Morris, "Have nothing in your [mathematics] that
you do not know to be useful, or believe to be beautiful."
Graduate Positions Available in the Computational Geometric
Mechanics group
Research positions for graduate students are available in the broad
area of geometric numerical
methods in geometric mechanics and control. A description of my current
research may be found in my research
statement, bibliography, collected publications, or
the abstracts below.
These positions are funded by the following research grants from the National Science Foundation in applied and
computational mathematics and engineering:
Please contact me by email if you are interested in any
of these positions. These are full-time positions, and students who are
interested in internship opportunities should read my policy on internships.
Hosting of Fedor Lynen Research
Fellows of the Alexander von Humboldt Foundation
As an alumni of the German-American Frontiers of Science symposium, I am
able to host research stays for Feodor
Lynen Research Fellows
of the
Alexander von Humboldt
Foundation. This supports post-doctoral researchers
(up to four years after completing a doctorate) for 6 to 24 months, and
experienced researchers (up to 12 years after completing a doctorate) for
6 to 18 months, divisible into a maximum of three visits over three years.
Computational Geometric Mechanics: Applying
discrete
differential geometry and discrete Lagrangian and Hamiltonian mechanics to
the construction of geometric structure-preserving numerical algorithms.
Computational Geometric Control Theory:
Construction of
real-time digital feedback control of mechanical systems using techniques
from geometric control theory and computational geometric mechanics.
Numerical Analysis: Derivation of accurate and
efficient
numerical schemes with good long-time geometric stability properties
by combining geometric integration with adaptive, spectral, and
multiscale techniques.

Melvin Leok is a tenured professor of mathematics at the
University of California, San Diego, where his research is supported in
part by grants from the National Science Foundation in applied and computational
mathematics, including a Faculty Early Career Development (CAREER) award.
He serves on the editorial boards of the Journal of Nonlinear Science, the
SIAM Journal on Control and Optimization, the LMS Journal of Computation
and Mathematics, the Journal of Geometric Mechanics, and the Journal of
Computational Dynamics.
Prior to joining UCSD, he was a tenure-track assistant professor of
mathematics at Purdue University, a visiting assistant professor of
control and dynamical systems at the California Institute of Technology,
and a T.H. Hildebrandt research assistant professor of mathematics at the University of Michigan,
Ann Arbor. At Purdue, he was a nominee for the Packard Fellowship for
Science and Engineering, and at Michigan, he received a Horace H. Rackham
Faculty Fellowship and Grant, and a Margaret and Herman Sokol Spring/Summer
Research Grant.
He received his B.S. with honors and M.S. in Mathematics in 2000,
and his Ph.D. in Control and Dynamical Systems with a minor in Applied and
Computational Mathematics under the direction of Jerrold Marsden in 2004,
all from the California Institute of Technology.
His primary research interests are in computational geometric mechanics,
computational geometric control theory, discrete geometry, and
structure-preserving numerical schemes, and particularly how these
subjects relate to systems with symmetry and multiscale systems.
He was the recipient of the SciCADE New Talent Prize in 2007 for his
work on Lie Group and Homogeneous Variational Integrators, and
the SIAM Student Paper Prize, and the Leslie Fox
Prize (second prize) in Numerical Analysis, both in 2003, for his work on
Foundations of Computational Geometric Mechanics. While a
doctoral student at Caltech, he held a Poincaré Fellowship
(2000-2004), a Josephine de Kármán Fellowship (2003-2004),
an International Fellowship from the Agency for Science, Technology, and
Research (2002-2004), a Tau Beta Pi Fellowship (2000-2001), and a Tan
Kah Kee Foundation Postgraduate Scholarship (2000).
As a Caltech
undergraduate, he received the Loke Cheng-Kim Foundation Scholarship
(1996-2000), the Carnation Scholarship (1998-2000), the Herbert J. Ryser
Scholarship (1999), the E.T. Bell Undergraduate Mathematics Research Prize
(1999), and the Jack E. Froehlich Memorial Award (1999).
