He was collaborative in nature with other fellow scientists with the degree of collaboration (DC) 1.00 and collaboration co-efficient (CC) 0.71. His most of authorship appearance came in 2-authored papers (216) between the duration of 1993-2020. Bose S from IISc was his highest collaborator with 41 documents. “Industrial And Engineering Chemistry Research” journal was the most used source for publication with 55 papers and the top keyword was degradation used 30 times.
Scientometric Portrait, Bio-bibliometrics, Degree of Collaboration, Collaboration Co-efficient.
Basically, bib-bibliometrics or ‘Scientometric portrait’ analysis is a study of an individual Scientist/author who are eminent in his single discipline or core area with a set of aligned researchers contributing together throughout his/her life. Bio-bibliometrics analyse “a unit of information generation” of the individual researcher to prove great value of concern, visibility of the good scientist, who is known or lesser-known. Bio-bibliometrics visualize different quantitative aspects using analytical methods by discovering and organizing in a functional manner, where the relationship between bio-data and bio-data elements. The term ‘biobibliometrics’ was first used by (Sen, S. K., and Gan, S. K, 1990) ‘informatics’ by (Kalyane and Samanta, 1995) and later it was called has (Kademani et al., 1996) ‘Scientometric portrait’.
Giridhar Madras is formally known as Madras G been born on 27th September 1967 in Salem district Tamil Nadu State, India. He took his professional degree in B.E Chemical Engineering from Annamalai University in (1988), post-graduation in M.Tech Chemical Engineering, IIT Madras in (1989), and completes his PhD program from prestige’s institute Texas AandM University (1993) in Chemical Engineering,
His major research area focuses on reaction kinetics, as applied to various systems and processes in the “environmental and energy sector”. Some of the major focus areas are:
1. Reaction with Macromolecules

The study purely concentrated on the Scientometrics Portrait of Dr Madras G scientist and former professor of IISc, Bangalore in the chemistry domain. Based on the previous literature many renowned methods have been incorporated in this study. The data had collected from the “Scopus Citation Indexing and Abstracting” database product of ScienceDirect using author key search. The study analysed his scientific publications (540 articles) to know the types of literature published, frequency of authorship occurrence and collaboration with fellow subject authors, research publications used to publish, highly cited articles and top preferred keywords and all the data was tabled using Microsoft excel.
Table 1 various scientific contribution has been made by Madras G in his professional and research carrier by writing in various scientific publications. Where, Table 1 describes the overall publication with a total of (569) publications in different documents format like scientific articles which are highest in total of (540) followed by Reviews (13), Conference Paper (8), Book Chapter (3), Letter (2), Editorial material (1), Note (1) and Short Survey (1) in Figure 1.

Scientometric studies are very important in highlighting the single scientists profile, achievement, awards, research publications and etc. Performed by a single author throughout his prolonged career with the association of different institutions, authors and communication channels. As an eminent scientist and professor, Madras G has contributed excellent work in this domain and is honoured with many awards. He guided many students and scholars throughout his life. Based on his research publications he was more collaborative in his work, compared to other scientists he was more collaborative with Indian author’s par with foreign authors. His h-index is 66, where got more than 5000 citations and is one of the top third productive authors of IISc, Bangalore.
