Brief curriculum vitae of Professor Martin Golubitsky
Professor Martin Golubitsky (Marty) was born April 5, 1945 in
Philadelphia, PA. He did his undergraduate studies at the University of
Pennsylvania, after which he went to MIT, where he received his PhD under the supervision of Victor Guillemin in 1970. He had several short-term postdoctoral
positions until he became Assistant Professor at Queens College in
1974 and Associate Professor in 1977. In August 1979 he joined the
faculty of Arizona State
University and stayed there until 1983. Marty then moved to the
University of Houston,
where he has been since. He became a Cullen Distinguished Professor in
1989.

Marty is married to Barbara Lee Keyfitz, who is currently the
Director of The
Fields Institute and President of the Association for Women in
Mathematics. They have two children, Alex and Elizabeth. Marty's
academic children are Martin Krupa (1988), Benoit Dionne (1990),
Chuanze Hou (1995), David Gillis (1996), and Pietro-Luciano Buono (1998).
His
mathematical work mainly focusses on singularity theory
and dynamical systems with symmetry. "When possible, I like to solve
an ODE without ever looking at the ODE. The question is: does the
structure of the equation tell you anything about the structure of the
solutions." For example, in the context of singularity theory, the
number of parameters gives information about the structure of the
solutions. However, lots of the classical models in applications that
he studied with David Schaeffer have symmetry and the structure of
solutions is not the standard one expected from singularity
theory. Here any particular solution that is not itself symmetric will
lead to new solutions --- its symmetric images. The effect of symmetry
on singularity theory has fascinated Marty for many
years. |

Since 1984 Marty has collaborated with
Ian Stewart. Marty knew Ian from his books and
wanted to meet him because of their similar backgrounds in Lie algebra
theory and their shared interest in catastrophe theory. "Ian was
visiting the University of Connecticut and as I happened to be
travelling between New York and Boston, I decided to look him up."
Unfortunately, Ian was not in his office. "I just asked around
and found out his home address. So, I went there and knocked on the
door..." And the rest is history. |

More recently, Ian and Marty have been studying coupled systems, or
networks, that are not symmetric. It turns out that here too the
solution structure may be different from what is expected using
singularity theory. The structures are due to the network
architecture and transcend structures due to symmetry. "The solution
structures are often very surprising and the research is still at a
very early theoretical stage. While Marty prefers to combine theory
with applications, "applications give life to the theory", there are
times when the theory preceeds the applications.
How to become SIAM President
Marty's association with SIAM started in the 1980's when Don Saari
asked him to be on the editorial board of the SIAM Journal on
Mathematical Analysis. Saari's aim was to get more dynamical systems
theory published in the journal. Marty Golubitsky accepted the offer
and decided that it was probably also a good idea to, finally, become
a member of SIAM. He has been a member since and also joined the SIAM
Activity Group on Dynamical Systems (SIAG/DS) when it was formed in
1989.
More serious involvement with SIAM came in 1990 when he was elected
to the SIAM council (1990-1995). "I believe that there is a place for
professional organizations like SIAM" he says and it was natural to
start at SIAM, since it had been good for SIAG/DS and dynamical
systems as a whole. In 1999 Marty became Chair of SIAG/DS. "Being SIAG
Chair had its educational side. I found out more about the ways that
SIAM could help SIAG/DS and the ways that SIAG/DS could help SIAM."
Indeed, Marty believes that all SIAM activity groups
(SIAM has 15 now) are extraordinary organizations. "This idea of smaller
focus groups is a great opportunity, both from an intellectual as well
as a professional point of view." In fact, early on, there was some
tension between SIAM and SIAG/DS. One could say that SIAG/DS was
a rather rebellious activity group that did not want to be controlled
by SIAM. "This was really due to the lack of communication between
people and SIAG/DS is now one of the three most active activity
groups. Its Snowbird meetings are always excellent.
Marty's two years as Chair of SIAG/DS (1999-2000) have not gone
unnoticed. "Several things in SIAG/DS needed attention: first of all,
we needed to have prizes. It is very important to have prizes and
mathematicians tend not to take this seriously enough." It is,
therefore, not surprising that the Moser
Lecture Prize and the Crawford
Prize were both initiated under his reign. The second major
initiative was the creation of a journal for SIAG/DS. Three events
happened almost simultaneously. First, there was much discussion
within the SIAG/DS community about whether SIAM should or should not
create a journal in applied dynamical systems. While on the Editorial
Boards Committee of the AMS (1994-1997), Marty had already been
involved with the idea of doing journals in electronic form. "It just
had to be an electronic journal; how else can you have free color and
animations!" Second, with technology improving, Mac Hyman (then SIAM
VP for Publications and now Past President of SIAM) and Mary Rose
Muccie (Journals Publisher of SIAM) wanted to try something electronic
and wanted to start with the proposed new journal for SIAG/DS. Third,
John Guckenheimer (SIAM President 1997-1998) had the idea of
combining the electronic journal with a web portal. Marty remembers
how they walked around downtown Washington at the SIAM CS&E
meeting in September 2000 and John described his ideas of providing a
web portal for the applied dynamical systems community. "This joint
proposal of an online journal associated with DSWeb was approved by
the SIAM Board and Council. It really was all John's idea and we then
divided up the responsibilities. It was only later that I found out
that within SIAM I had been named the founding editor of the SIAM Journal on Applied Dynamical Systems
(SIADS)."

It is clear that Marty
will climb high; his parents are proudly watching on the side. The
picture was probably taken in 1953. |
Marty is studying for a
graduate analysis exam in 1967. |
Based on his SIAM experiences with the Council, SIAG/DS, and SIADS,
Marty was asked to asked to run for SIAM VP at Large in 2001. The
nomination for President came after a series of coincident activities.
- In December 1999, Margaret Wright asked Marty to join her in
co-organising the SIAM 50th anniversary meeting in
Philadelphia, 2002. "Margaret and I were on the SIAM Council at the
same time and we have been friends ever since."
- During 2000-2003 he was on the AMS council; combined with his
experiences as VP at Large, this meant a wealth of knowledge about how
such big organizations are run.
- He was now an experienced Editor-in-Chief of SIADS.
"On top of all that, Barbara was SIAM Vice President for Programs,
which was her education for becoming director of
The Fields
Institute, so it runs in the family."
What the SIAM President will do
Marty grins a bit at my question of what he is going to do as
President. "That is exactly what Jim Crowley (the Executive Director
of SIAM; ed.) asked me at the Joint Math Meeting in Phoenix in January
2004!"
He begins by explaining what SIAM actually does. Most of us know
that SIAM runs a conference and publication programme. Furthermore,
SIAM is the overseeing (and controlling!) body of the SIAGs and
actively pursues links with industry. However, SIAM also puts a lot of
effort into professional issues, in particular with the US government
in Washington. "SIAM is very proud
of its established Washington lobby presence and makes sure that
(Applied) Mathematics is well represented." Furthermore, SIAM can
play a role at an international level, because roughly 1/3 of its
members are not citizens of the United States. This also explains
SIAM's efforts to organize conferences outside the US. For
example, the SIAM meeting on Optimization in Stockholm, Sweden this
May looks like it will be a big success. "The past three SIAM
Presidents were very much
involved with establishing a permanent Washington presence. I support
this activity and will do what
I can to help, but I also feel that the Washington presence is established
now and that there are other more experienced people on the SIAM Policy
Committee who can direct this activity."
Instead, Marty wants to focus more on the excitement of
mathematics. SIAM has always taken education issues very seriously
(there is a SIAM Vice President for Education and a SIAM Education
Committee), but recently there has been more emphasis on getting young
people interested and excited about mathematics and computational
science. In particular, Marty envisions a website very much like DSWeb
with lots of exciting mathematics that is highly visual and
interactive, but also conveys the importance of mathematics and
computational science in many
applications. "Take for example the genome project; the classification
of the human genome took only a fraction of the expected time. This
was due to increasingly sophisticated mathematical algorithms, but
exactly what kind of mathematics was used and how did it make such a
difference?"
This website would be dedicated to students who are at least at
sophomore level (they must have had Calculus). "Certainly in the US,
but also in other countries there is a marked decline in the number of
students who study mathematics and computational science. Many
students choose subjects like
biosciences, economics, or business studies instead. They find such
studies more interesting and exciting and do not realize that even
with such career plans, they would greatly benefit from a degree in
mathematics. The website would convey the enthusiasm and fun of
mathematics using practical applications to show how useful and
important it is." The idea is to make several, "I don't know, 20, 100,
lots", so-called vignets that all consider a particular topic
in applied mathematics. These vignets are highly visual and
interactive and could really be about anything. "The idea behind it
is: where is the math?" Katherine Socha (St. Mary's College of
Maryland) has agreed to lead this project.
[At this point, Marty and I are interrupted by another participant
of the PASI
2005 meeting where I am interviewing him. The participant points
out what a fantastic idea this is and that he can see many uses for
such a wealth of information.] "See, that is the typical response I
get from people who I tell about this!" Marty continues
enthusiastically claiming that it is vital to communicate
mathematics. "SIAM has the skills within its membership to produce
impressive professional material that can motivate students,
and as a community we should make this a priority."
The website is clearly still under development, but will eventually
materialize under
http://www.whydomath.siam.org/ where students
can go and get a feeling of "I can see myself doing this" and maybe
get ideas for an undergraduate project from the site. "This will be a
major resource for students, and faculty, and... Members of Congress
in Washington."
