Evolutionary photonics: new designs inspiration from natural
systems
August 7, 2006
Abstract: Diverse designs of naturally evolved nano-scale
periodicity are known to generate optical functionality in the
living world. While such systems have clearly evolved for biological
purposes, they are increasingly offering inspiration and design
protocols for applied photonic technologies. This lecture will
present both an overview of the knowledge base of this emerging
field of study, as well as several exciting recent discoveries
that reflect nature’s optical expertise and design ingenuity.

Molecular Analysis and Design of Silica Biogenesis in Diatoms
August 25, 2006
Abstract: Silica Biotechnology. Silica formation by Diatoms
is a very rapid, highly controlled process that takes place within a
specialized intracellular compartment termed the silica deposition
vesicle (SDV). Recently, novel phosphoproteins (silaffins) and unusually
long-chain polyamines have been identified and implicated in Diatom
biosilica formation. Research in Silica Biotechnology aims to establish
the molecular tools allowing the creation of mutated Diatoms that produce
tailored silica nanostructures adapted for nanotechnological applications.

Probing Worms’ Mind and Cellular Behaviors with Microfluidics
8 September 2006
Abstract: In this seminar, I will talk about our efforts
in designing, fabricating, and using microfluidic chips to study biological
problems. The techniques that we use to make these microchips are similar
to those used in microelectronics industry. We take advantage of physical
phenomena at the micro/nano scale to deliver stimuli, control microenvironment,
achieve separation, and carry out analysis. I will give two examples of
using microfluidics on C. elegans sensory biology: (1) to study oxygen sensation,
and (2) to study pathogenic learning. I will also give some examples to
use microchips for studying cell adhesion and performing subcellular separation.
We believe that what microfluidics brings to medicine and biology today
and tomorrow is parallel to how microelectronics revolutionized computation
in the last few decades.

Biologically Inspired Air Vehicle Design Principles
2 October 2006
Abstract: No other air vehicle design space has presented the mix of challenges
as that of miniature flight platforms. By definition these tiny platforms are unmanned and
endeavor to invade the flight regime of birds and insects. In order to do so, the creators
of these aerial robots must address the same physical design constraints which have already
been mastered by the world of airborne biology, including low Reynolds number aerodynamics,
high energy density, and extreme miniaturization. This presentation focuses on the high degree
of innovation required to make practical miniaturized flying machines on the scale of small
birds and insects.

Inspiring slimes: What hagfish slime can tell us about predator defense,
the cytoskeleton, and high-performance protein fibers
November 7, 2006
Abstract: Hagfish are notorious for their ability to produce alarming amounts
of mechanically-intriguing defensive slime when they are provoked or stressed. In this seminar,
will summarize what we know about this fascinating biomaterial and describe two lines of inquiry
that have unexpectedly sprung from our research on hagfish slime. The first is the biomechanical
design of the animal cell cytoskeleton, which includes an elaborate network of 10-nm diameter
filaments called "intermediate filaments." The protein threads that permeate hagfish slime consist
of nearly pure bundles of intermediate filaments, and provide an excellent model for exploring the
mechanical behavior of these nano-scale filaments. Hagfish slime threads undergo a dramatic
conformational change when they are stretched in water, the result of which is a fiber that rivals
the properties of spider dragline silk. I will also talk briefly about our recent efforts to artificially
produce silk-like fibres from hagfish slime thread proteins.

Enhanced swimming performance by flow control in marine mammals
30 October 2006
Abstract: Optimization of energy by whales and dolphins requires
adaptations that reduce drag, and improve thrust production and efficiency.
The control of flow over and around the body of whales, therefore, is critical
to efficient swimming performance.

Fly lends an ear to microphone design
April 9, 2007
Abstract: Professor and Chairman of Mechanical Engineering
at SUNY Binghamton has been awarded a DARPA grant to develop for military
purposes innovative sound processing technology inspired by the ear of a
small fly. In small insects like Ormia, millions of years of evolution have
given rise to innovative approaches to the problem of miniaturization. It
was a cross-disciplinary study by Miles, Ronald Hoy of Cornell and Daniel
Robert of the University of Zurich that determined the workings of a unique
structure inthe ear of Ormia and paved the way for Miles’ latest project.
That structure, the intertympanal bridge, allows the insect to locate, in
pitch dark and with deadly accuracy, the crickets upon which it preys, even
though its ears are located less than 100 microns apart. Miles is also in
the second year of a three-year $1. 1 National Institutes of Health grant
to develop the world’s smallest directional microphone
for use in hearing aids.

Jellyfish Biomechanics and Optimal Vortex Formation
April 23. 2007
Abstract: Professor Dabiri’s research examines the mechanics
and dynamics of biological propulsion, broadly defined to include
the transport and transfer of fluid momentum in both stationary and mobile
systems. Applications include aquatic locomotion via pulsatile jets, fluid
dynamic energy conversion, and cardiac flows. A current thrust of his research
is the study of jellyfish swimming as a model system for understanding behavioral
and fluid dynamic aspects of animal locomotion in general. His group develops
and applies new experimental and theoretical methods in fluid dynamics to
investigate in situ and in vivo fluid transport, with the goal of discovering
general bio-inspired design principles that can be implemented in engineering
systems.

New breakthroughs in biomimetic compound eye research
date TBA
Abstract: research interests include: biomineralization, biomimetics,
multifunctional biomaterials, crystal engineering, nanofabrication, control of crystal
nucleation and growth, colloidal assembly. She has discovered a unique function of
biologically formed single calcite crystals serving not only as skeletal armor, but also
as an array of microlenses with nearly-perfect optical performance. In addition, while at
Lucent she has developed a new biomimetic approach for the synthesis of ordered mineral
films with highly controlled nucleation density and crystal sizes using organized organic
assemblies.
