My major interest in teaching is introducing optimization
techniques into the undergraduate cur-riculum and bringing them to bear
on undergraduate design activities. For this purpose I have introduced
into the curriculum 3 undergraduate optimization courses - a general optimization
course, a course on experimental optimal engineering design and a composite
structures and material optimization courses. Additionally, I have initiated
and collaborated with colleagues on the introduction of mini-design projects
into structures and vibration-and-control courses.
Curriculum Development at the University of
EGM 6365 Structural Optimization: Developed
and introduced this course at Virginia Tech and then at the university
of Florida. Course seeks to introduce students to modern methods for structural
design mostly in the fields of aerospace and civil engineering. Taught
first in 1996 as special topics course, and in Fall 1998 as a regular course.

EGM 4473 Experimental Optimum Engineering Design:
and introduced this course in 1996 as a special topics course and then
as a regular course in 1997. The course seeks to demonstrate to students
how both analytical and experimental techniques are used in the design
process. The course is centered around a project. This innovative course
has drawn praise from graduate students in industry who took it as a special
topic course. One of the students in the 1997 course, Terry Siorek, a specialist
in hematology instrumentation, col-laborated on a paper describing the
project in this year Multidisciplinary Analysis and Opti-mization conference.
The 1996 project, developed with Dr. Jenkins of AeMES, was de-scribed in
a paper published in Structural Optimization in February 1998. A set of
notes was developed for the course and made available to students on the
course web page (http://www.mae.ufl.edu/haftka/eoed/).
EAS 4240 Aerospace Structural Composites: Introduced
an optimization segment into the course as a guest instructor in a two-week
segment in order to broaden the design experience of the students. This
will be further expanded in Spring 1999, when I will teach the course out
of a newly developed textbook (see below).
EAS 4200C and EAS 4210C Aerospace Structures 1,2:
mini-design projects for these two courses, using the remarkable capabilities
for optimization now available in commonly available spreadsheet programs
(Microsoft Excel, Lotus 1-2-3, Quatro Pro).

My research area is structural and multidisciplinary optimization. In the
area of structural opti-mization, my students and I investigate diverse
applications ranging from the development of algorithms to the experimental
validation of reliability based optimization. The focus of many of these
investigations is the design of structures made from composite materials.
The combinato-rial nature of the stacking sequence design for composite
laminates is particularly challenging, and has motivated my work in the
development of genetic algorithms for this application.
In the past few years I have focused much of my interest in optimization
methodology into methods that are used for experimental optimization. These
methods, commonly known as de-sign-of-experiment techniques, are becoming
increasing appropriate because of the growing similarities between computer
simulations through complex numerical models and physical ex-periments.
In the area of multidisciplinary optimization I have focused on combined
structure and control optimization of space structures, and on combined
aerodynamic and structural optimization of aircraft wings. The first topic
has a strong experimental flavor, because I believe that much of the challenge
in the area of structural control derives from the discrepancy between
theoretical re-sults and what can be achieved in real applications. In
the area of combined aerodynamic and structural optimization, I am currently
working with three other faculty members and five gradu-ate students in
a major effort of developing design methodology for the next generation
super-sonic transport. I am also working with a team of colleagues and
students at Virginia Tech on the design of a truss braced transport, with
the truss brace allowing for a substantial improvements in aspect ration
and lift to drag ratios.
Another multidisciplinary program involves the design of miniature unmanned
aerial vehicles. The focus in this research is on the smallest size that
can be achieved with present day technol-ogy. I am working with seven other
faculty members in AeMES and one in Electrical and Com-puter Engineering
on various aspects of aerodynamics, control and performance of miniature
I like to work with colleagues, and I attempt to share all of my graduate
students with other fac-ulty members or NASA researchers. This arrangement
benefits the students, and it helps me cre-ate interactions with and learn
from my colleagues. This interaction results also in joint papers and joint
research proposals. Over my 13 years at Virginia Tech, I have written papers
with 8 faculty colleagues in my department and 8 in other departments.
At the University of Florida I have published papers with 4 faculty members.
Since 1991 I have also published papers with 10 NASA researchers and colleagues
from other many other countries including, Belgium, Den-mark, France, Germany,
Israel, Italy, Japan, Poland and Turkey.
I believe that many researchers and industrial practitioners do not have
the time to read the large numbers of papers that are published in their
field. I have invested much effort in keeping abreast of the latest development
in the areas of structural and multidisciplinary optimization and I attempt
to use this to provide a service to the engineering community in these
fields. I have written a textbook (with Gürdal) which has an extensive
list of references, and which we update regularly. I have written several
survey papers, and I review about 30--40 papers per year, mostly for the
AIAA journals. I have also served as associate editor of the AIAA Journal
1980--1982. In reviewing papers I always attempt to call the authors attention
to related work that they might have overlooked. I also organized and chaired
many sessions in scientific meetings (mostly AIAA).
Recently I have focused on improving the cooperation between industry
and universities in the area of multidisciplinary optimization. In May
of 1993 I have organized (together with my colleagues Grossman and Mason)
an industry-university workshop on multidisciplinary aircraft design attended
by most of the major aircraft manufacturers. The recommendations of the
workshop for changes in the way universities, industry and government interact
were published in July 1994 in Aerospace America. I have also intensified
my own work with industry, and recently I have been working on projects
with Boeing, McDonnell Douglas and
the Ford Scientific Research Laboratory.
I am the president of the
International Society of
Structural and Multidisciplinary Optimization (1995--1999). This young
society (founded by George Rozvany in 1991) has about 400 members, and
is concerned with promoting international research and education in Structural
and Multidisciplinary optimization. I am also a member of the AIAA Technical
Committee on Multidisciplinary Design Optimization. I continue as a member of
the executive committee of ISSMO.
