recognition techniques. Starting out as a
mechanical engineer and having done considerable
amount of machine health monitoring and prognosis
in the mid-1980s, as well as neural network
learning, control and signal processing, the
speaker moved on to work in the handwriting,
speaker, speech recognition fields, making a
connection among these fields and health
monitoring. The similarities of these fields are
explored and a summary of the research of the last
decade in conjunction with the civil engineering
department of Columbia University are discussed.
Cepstral analysis and deep neural networks
originally designed for speaker and speech
recognition are at the heart of the techniques
that are in this research effort that began over a
decade ago. Realizing the similarities in the
vibration of structures, such as bridges and
buildings, machinery, such as gear-meshes and
bearings, and the human vocal tract kicked off
this </span>multi-disciplinary<span
style="color:rgb(11,83,148)"> effort. Some
techniques developed in this approach are shown
together with results for health monitoring and
structural damage detection. The current
affiliates in this research, Raimondo Betti (Prof.
of Civil Eng.), Azin Mehrjoo (PostDoc), and Kyle
Hom (4th year Doctoral Student) will be at the
seminar and available for discussions.</span></p>

Professional Practice in the departments of
mechanical engineering and electrical
engineering. He earned his BS, MS, and Doctorate
from Columbia in 1984, 1985 and 1991
respectively. The author of the first and only
comprehensive textbook on Speaker Recognition, for
over three decades he has been involved in
research and development in learning-adaptive
control, neural network learning, biometrics,
speech, speaker, face, object, emotion, and
language recognition, as well as
Internet-Commerce, and more. As the president of
Recognition Technologies, Inc. for 22 years, he
developed the multiple award-winning RecoMadeEasy®
Recognition Engine and CommerceMadeEasy®
software. As an Adjunct Professor at Columbia for
thirty years, he taught in the ME, EE, and CS
departments and advised PhD students in civil. In
2023, he was selected as one of only 11 finalists
for the 5 Presidential Awards for Outstanding
Teaching. He was a Research Staff Member at the
IBM T.J. Watson Research Center from 1991 to 2001,
working on handwriting, speaker and speech
recognition. He is the recipient of three best
paper awards from IEEE and Society of Experimental
Mechanics, 13 issued patents and over 120
peer-reviewed publications.</font></p>
