Donald Barnhart has been developing optical design and analysis software in Wolfram

Research s Mathematica since 1991. His Optica software package, introduced in 1994, is used by thousands

of scientists across the world. Donald developed the world's rst successful high-resolution holographic

instrument to measure three-dimensional velocity elds in uids, the results of which appeared on the

front cover of Applied Optics in 1994 and are cited in more than 200 publications. Donald received the

Rank Prize in 2001 for the best electro-optics Ph.D. dissertation in the United Kingdom. The optics group

to which he belonged at Loughborough University received the Queen's Anniversary Prize, awarded

personally by the Queen at Buckingham Palace. Since 2004, Donald has been the chief optical scientist for

iCyt Mission Technology, a Sony USA subsidiary that produces ow cytometers for stem cell and cancer

research, in addition to his ongoing Optica business.

iCyt

" Since the completion of my Ph.D. in 2001, I have accumulated a wide range of experience and

expertise in both academic and industrial settings. For the past seven years, I have served as the principal

optical scientist for i-Cyt Mission Technology (now a subsidiary of Sony). I have designed and developed

nearly all of the optical subsystems used in the ow cytometers produced by i-Cyt today. With a retail

price tag of more than a million dollars per unit, these ow cytometers are a con uence of the most

advanced optical, electronic, and signal processing hardware technologies available. My role and

responsibilities at i-Cyt have allowed me to test the limits of optical design and oversee the entire optical

product development process from conception through to production for dozens of commercial systems.

My role at i-Cyt also has enabled me to experience rsthand the entire business development cycle from

which a small startup company evolves and grows into part of one the largest and most prestigious

corporations in the world, Sony.

Mathematica

" A close association with Wolfram Research since its founding in 1988 has allowed me to acquire and

maintain a very high level of pro ciency in the Mathematica computer language, which I have applied to a

wide range of applications, including spatial modeling and the Optica product discussed next.

Optica

" I have been experimenting with optical models in Mathematica since 1991. This has culminated in a

business venture to create optical design and analysis software called Optica, which was initially released

in 1994 and originally distributed by Wolfram Research. In 2004, I licensed my Optica business to i-Cyt.

More recently, in 2009, I founded my own business, Barnhart Optical Research, LLC, which distributes

Optica through its Optica Software division and now supports a wide range of research and development

efforts as well.

" Since their introduction, my optical modeling products have been used by thousands of scientists

across the world at businesses and academic institutions such as Lawrence Livermore, Los Alamos,

NASA, Sandia National Laboratory, Harvard, Oxford, Cambridge, Microsoft, Canon, Northrop

Grumman, Intel, the Jet Propulsion Laboratory, and, of course, Sony. In order to support Optica, I

regularly correspond with scientists from around the world who are working on a diverse array of optical

applications that include solar energy, extreme ultraviolet lithography, laser systems, and telescopes.

Constant exposure to the technical concerns of other scientists has given me a unique insider s

perspective on a wide range of topics that all use the cutting edge of technology. Most recently, I have

employed Mathematica and Optica in the high-performance computing (HPC) environment at R-Systems

to solve a modeling problem in 14 days that would have required three years to run on a single laptop

computer.

Academic Reputation

I completed my Ph.D. work in 20011, receiving the highly competitive Rank Prize for the best

electro-optics Ph.D. dissertation in the United Kingdom, and our optics group at Loughborough

University received the Queen's Anniversary Prize, for which I traveled to Buckingham Palace and

personally met the Queen of England. In 1994 I established an international reputation in my eld when,

building on work done for my master s degree, I demonstrated the world's rst successful holographic

instrument to measure three-dimensional velocity elds in uids2. This accomplishment was reported on

the front cover of Applied Optics journal9and resulted in a patent3.. I have since earned recognition as a

founder of the holographic velocimetry discipline and as a world leader in holographic metrology work.

The 1994 Applied Optics article has alone been cited on more than 185 occasions in refereed journal

publications of other authors.

More recently, the results of my work have been twice published in the Proceedings of the Royal

Society of London6, a venerable organization headed at one point by Sir Isaac Newton. In addition, I have

held research collaborations with groups from ve different European universities that include:

Loughborough University (England), the University of Delft (Holland), University of Oldenburg

(Germany), University of Zaragosa (Spain), and University of Marburg (Germany). I regularly give

invited presentations in numerous venues. I most recently gave an invited presentation on optical design

and high performance computing at the Coalition for Academic Scienti c Computation meeting held in

Arlington VA (March 2011).

Other Research Interests

In addition to the topics mentioned above, over the years I have maintained a strong interest in

spatial modeling and remote sensing of ecological systems, most notably, the Illinois tall grass prairie.

Since 1987 I have been activity involved in reconstructing the prairie ecosystem on our family farm. The

Barnhart Prairie Nature Preserve now includes more than 110 acres of restored prairie. I hope that

research projects carried out on this land will allow me to pursue my interest in new applications of

spatial modeling and remote sensing to precision agriculture.

Other research interests include three-dimensional shape measurement, three-dimensional

displays, high performance computing, and holographic microscopy. I am particularly interested in

application of digital holography to ow-cytometry.

Teaching Interests

My accumulated technical knowledge and real world practical expertise in research and

development, industrial design, and entrepreneurship have prepared me, I believe, to offer students a

rich learning experience. For the past ve years, I have regularly been invited to teach optics classes at the

University of Illinois as a visiting lecturer. I would enjoy a larger and more formal opportunity to engage

with students in both theoretical and practical contexts.

Professional Interests

As the lead developer of Optica Software, I am continually developing this software as a

consultant for new business applications in a wide range of professional settings involving optical

systems design and modeling.

A second professional interest involves the development of a fully digital holographic camera

with numeric reconstruction of the digitized holographic information. In particular, I am using a

photochromic material known as bacteriorhodopsin (BR) as a temporary optical storage buffer to allow

the holographic information to be digitally scanned1. This use of BR for digital holography is a completely

new concept that I have personally originated. In contrast to a CCD camera sensor, which can only record

millions of pixels, a digital holographic camera based on BR can record 10-100 billion pixels of

information. This corresponds to a holographic object space that occupies 1-10 cubic centimeters volume

with sub-micron spatial resolution. The two principal applications of this instrument are in the areas of

biomedicine and nanotechnology research:

1.three-dimensional, velocity- eld mapping of uids, surfaces, and surface- ow interaction,

2.digital holographic microscope for high-resolution, volumetric imaging.

" A third interest is the development of new optical instrumentation for remote sensing. This interest is

connected with a personal endeavor to restore more than 100 acres of farmland into native tall grass

prairie (see below). Although my experience in this research area is still limited, I wish to develop new

instrumentation for mapping out species distributions in high-diversity, natural plant communities, such

as the tall grass prairie, on a spatial scale that enables the individual plants to be accurately located,

identi ed, and cataloged. In addition, the same instrumentation can have applications in commercial

agriculture, for which research/business funding is more abundantly available.
