Draft:Gautam Dasgupta

Gautam Dasgupta (Bengali:  গৌতম দাশগুপ্ত.; born October 13, 1946)  is an American researcher/educator of engineering mechanics. He has contributed to analytical continuum mechanics, computer mathematics, and finite element analysis.[1] He is particularly known for his work in anisotropic elasticity, numerical integration procedures for viscoelastic responses, and the development of stochastic shape functions and stochastic Green’s functions. Dasgupta has been a faculty member in Columbia University since 1977. In addition, Dasgupta has been a singer-song writer in Bengali language has published albums since 1984. He has also authored Textbook on Finite Elements: Finite Element Concepts: A Closed-Form Algebraic Development (1st ed. 2018 Edition).

Early life and education

edit

Dasgupta was born in Kolkata, West Bengal, India. He completed his Bachelor of Engineering (Civil) and Master of Engineering (Applied Mechanics) at Bengal Engineering College, Calcutta University, in 1967 and 1969, respectively.[2] Dasgupta then pursued his doctoral studies at the University of California, Berkeley, where he obtained his PhD in Structural Engineering and Structural Mechanics in 1974.[2] [3]He has held the position of honorary professor at Tsinghua University in Beijing, China, since 2013.  During the G20 Sumit in Indonesia, he was awarded a G20 Professorship by the S20 committee headed by Sir Gordon Duff. [2][3]

Career

edit

Dasgupta began his academic career as a technical teacher trainee in Applied Mechanics from 1967 to 1970 in Bengal Engineering College, West Bengal, India, followed by a lecturer ship at Goa Polytechnic, Goa, India in 1970.  He worked as a post-doctoral fellow at the University of California, Berkeley, from 1974 to 1977.[4] In June 1977, Dasgupta joined Columbia University in Civil Engineering and Engineering Mechanics.[4] At Columbia, Dasgupta has been involved in various research projects and conferences, including serving as the founding chair of the International Mathematica Symposium and as vice chair of the Turing Centenary Colloquia.[4] He has chaired ASCE and ASME groups focusing on elasticity, structural dynamics, probabilistic analyses, and biomechanics. [4][3][5]

Dasgupta has been involved in various global research collaborations, including projects with the World Monument Fund, the Japanese group for the preservation of Angkor, and the Disaster Prevention Committee in Osaka, Japan. He has held the position of honorary professor at Tsinghua University in Beijing, China, since 2013. [3][5]

In addition, Dasgupta has contributed to discussions on resilience and sustainability at the Spring and Fall Disaster Simulation Seminars at the Nakanoshima Center, Osaka University, Japan. [3]

Research Interests

edit

Dasgupta’s research focuses on computer-aided engineering graphics and finite element analysis. His contributions include alternative representations of elastic-viscoelastic analogies, modeling embedded foundations, and stochastic finite element methods. His work has also involved the development of impedance matrices for unbounded media and embedded structures, cloning algorithms, and applications of asymptotic methods.[1][2][6]

Consulting experience

edit

His consulting experience includes roles at Bechtel Corporation, Weidlinger Associates, AMOCO, NASA-Lewis, Business Advantage (Finland) and Knowledge Solutions Group (Japan). [2][6]

Gautam Number and Sustainability Index Theory

edit

The Gautam number, denoted as 𝐺𝑛, is a metric introduced by Professor Eizaburo Tachibana, Dean Emeritus of Architecture at Osaka University, to quantify resilience in the context of extreme disasters. It is defined as the ratio of the return period to the recovery period, with both metrics typically measured in years.[2][6][7]

In subsequent research, Dasgupta developed the concept of the time rate of resilience, known as the sustainability index. This index measures the rate at which resilience is maintained over time. The Gautam number and related tensorial concepts have also been incorporated into modern AI computations in areas such as climate sciences and transparency in governance. [2][6][7]
