<br />
== Life and career ==<br />
Siddavattam was born in a village near Piler in present-day Madanapalli district, [[Andhra Pradesh]], India. He completed his undergraduate studies with a major in biology and earned a PhD from [[Sri Venkateswara University]], Tirupati, in 1985.<br />
<br />
During his tenure at SKU,{{Clarify|date=February 2026}} he received international fellowships, including the [[DAAD fellowship]] from the Government of Germany and the Commonwealth Academic Staff Fellowship from the [[British Council]], United Kingdom. He undertook postdoctoral research at the Institute of Genetics, [[University of Bayreuth]], Germany, under Walter Kling Müller, and at the [[John Innes Centre]], England, under M. J. Merrick. His work during this period focused on microbial genetics and molecular microbiology.<ref>{{cite web |title= Prof. Dayananda Siddavattam appointed Vice Chancellor of Gitam University, Vizag |url= https://herald.uohyd.ac.in/prof-dayananda-siddavattam-appointed-vice-chancellor-of-gitam-university-vizag/| website= Herald University of Hyderabad |access-date= 2 Feb 2026}}</ref><br />
<br />
In 2004, Siddavattam joined the [[University of Hyderabad]] as a professor and served there until his retirement in 2022. He held several administrative positions at the university, including Senior Professor, Dean of the School of Life Sciences, and Chief Proctor. He then served as the Vice-Chancellor of GITAM University, Visakhapatnam.<ref>{{cite web |title= Prof. Dayananda Siddavattam appointed as Vice Chancellor of Gitam |url=https://telanganatoday.com/prof-dayananda-siddavattam-appointed-as-new-vc-of-gitam | website= Telangana Today |access-date= 2 Feb 2026}}</ref><br />
<br />
Siddavattam's research has primarily focused on bacterial [[phosphotriesterase]]s (PTEs), enzymes capable of hydrolyzing organophosphate compounds including insecticide residues and nerve agents. His work demonstrated the occurrence of opd genes encoding PTEs on mobile genetic elements and their lateral transfer among soil bacteria. His research group also reported the presence of twin-arginine transport (TAT) motifs in PTE signal peptides and showed that these enzymes are inserted into bacterial membranes in a prefolded state as part of a multiprotein complex associated with the TonB transport system, which is involved in nutrient transport in Gram-negative bacteria.<ref>{{cite web |title= Prof. Dayananda Siddavattam- Google Scholar Profile |url=<br />

He has also served as a consultant to pharmaceutical and biotechnology organizations.<br />

== Honours and recognition ==<br />
<br />
Siddavattam has received several national and international recognitions, including the International Research Development Award from the Wellcome Trust, United Kingdom. He is an elected Fellow of the Indian National Science Academy, the Indian Academy of Sciences, and the National Academy of Sciences, India. He has also received the J. C. Bose National Fellowship from the [[Science and Engineering Research Board]], [[Government of India]],<ref>{{cite web |title= The list of New fellows awarded during the year 2020-21 in the J C Bose Fellowship |url=https://www.indiascienceandtechnology.gov.in/sites/all/themes/vigyan/images/banner_articles/JC%20Bose%20fellows%202020-21.pdf | website= India Science and Technology, Government of India |access-date= 2 Feb 2026}}</ref><ref>{{cite web |title= Prof. Dayananda Siddavattam selected for J C Bose Fellowship |url=https://herald.uohyd.ac.in/prof-dayananda-siddavattam-selected-for-j-c-bose-fellowship/ | website= University of Hyderabad |access-date= 2 Feb 2026}}</ref> and the Prime Minister [[Professorship]] from the Anusandhan National Research Foundation.<ref>{{cite web |title= PM Professors 2025 |url= https://serb.gov.in/assets/pdf/PM_Professors_2025.pdf |website= Serb Gov |access-date= 2 Feb 2026}}</ref><br />
