A Curious Life: Dr. Allen Bard stays focused on fundamental research
Client: UT College of Natural Sciences
Curiosity may be the most powerful scientific tool, but hard work runs
a close second. So says Dr. Allen Bard, who has used both to great effect
in a scientific career that has spanned nearly half a century so far.
During that time, Bard has amassed an impressive list of discoveries,
publications and scientific awards. Among the highlights, he co-discovered
electro-chemiluminescence, the emmission of light when molecules exchange
electrons which today serves as the basis for highly sensitive immunoassays.
He also developed the scanning electrochemical microscope, used to observe
chemical reactions between handfuls of atoms. And his electro-chemical
research has contributed to pollution remediation, semiconductor design
and solar power.
But when discussing his achievements, Bard prefers to focus on a different
aspect of his work.
“If you want to know the most important thing I’ve done,
it’s train students and post- docs,” Dr. Bard said. Regarding
his research, he said, “whatever I tell you is important now is
not going to be important in 10 years, but the students will be. That’s
really it.”
As the Norman Hackerman-Welch Regents Chair in Chemistry and director
of the Laboratory of Electrochemistry, Bard leads a team of graduate
students and post-doctoral fellows investigating electro-chemistry and
its applications.
His team has led the development of these fields in recent years, with
Bard guiding his junior colleagues along the often-difficult road to
discovery.
“As I tell my students, most of the time research is not going
well,” Bard says. “That’s the real truth. There are
a hundred ways things can go wrong – machines break, chemicals
are impure – and so you just keep fighting. In other words, nature
gives up its information, but not very willingly.”
After receiving his bachelor’s from the City College of New York
and a doctorate in chemistry from Harvard University, he came to
the University of Texas at Austin in 1958 to pursue electro-chemical
research.
“It’s about the drive to understand, to push the frontier,
Bard says. “Sometimes you can see an application, but a lot of
times you can’t.”
While fundamental research doesn’t always have clear applications
at first, he adds, history shows that it often pays off handsomely. Such
was the case with electrogenerated chemiluminescence, which dramatically
improved the sensitivity of immunoassays, a ubiquitous test in the life
sciences, pharmaceutical research, environmental science and industry.
“We just wanted to know the details of how electrons transfer
among molecules,” Bard says. “It was interesting to see this
new phenomenon. It was only after 20 years that we saw a possible application
and developed it. And that has happened continually throughout my career.”
Looking forward, Bard sees some of the most interesting problems at
the interface between chemistry and biology.
“Biological systems are basically chemical systems,” he
says. “They are exceedingly complicated chemical systems, but they
are chemical systems and can be interpreted purely as such.”
He also sees significant work ahead in energy research, particularly
converting solar energy into electricity efficiently, and in analytical
chemistry, where scientists would like to find techniques to analyze
individual molecules.
Investigating these areas may lead to more awards for Bard, a member
of the National Academy of Sciences and recent recipient of the 2004
Welch Award in Chemistry in recognition of his lifelong achievements.
Regardless, he will likely accept them with modesty.
“Awards are nice,” Bard says. “But I always tell my
students you only go through two stages in your career — when you
are underappreciated and when you are over appreciated.”
“The most important thing is to work hard. That’s really
it,” he says.
