|
|Surindar Kumar Trehan obtained [[Doctor of Philosophy|PhD]] (1958) from [[University of Chicago|University of Chicago, USA.]] He was [[Dean (education)|Dean]], Science Faculty, and CSIR Professor Emeritus, [[Department of Mathematics, University of Manchester|Department of Mathematics]], both at [[Panjab University|Punjab University]], [[Chandigarh]] (1980-82, 1989).
'''Academic and Research Achievements:''' Trehan made significant contributions to our understanding of the stability of force- free [[magnetic fields]], of [[Cylinder|jets and cylinders]], and of [[Inhomogeneous cosmology|inhomogenous]] plasmas. His work on the mathematical treatment of [[Gas|gaseous polytropes]] in the presence of a magnetic field was noted with keen interest. He also made contributions to the study of hydromagnetic waves and rotating gaseous masses. He carried out nonlinear studies in [[magnetohydrodynamics]]. He provided, for the first time, a consistent account of the [[Modulatory space|modulational]] stability of bounded systems taking into account the [[boundary (thermodynamic)|boundary]] conditions consistently.
'''Other Contributions:''' Dr Trehan served on many expert committees of [[Council of Scientific and Industrial Research|CSIR]], [[University Grants Commission (India)|UGC]], etc.; [[Governing Council of Indian Statistical Institute and Indian Association for the Cultivation of Science]]
(The links indicated in red refers to " not created yet") ; and Member, [[Intelligence and National Security Alliance|INSA]] Council (1977-79). He was also Editor, ''[[Bulletin of the Astronomical Society of India]]'' (1980-91); Member, Editorial boards of: ''Journal of [[Astrophysics|Astrophysics and Astronomy]],'' and some other journals; and Editor of INSA Publications (1979-82).
'''Awards and Honours:''' Dr Trehan received the [[Shanti Swarup Bhatnagar Prize for Science and Technology|SS Bhatnagar Prize]] (1976); [[Dr. B. C. Roy Award|BC Roy Award `Eminent Person in Sciences’]] (1989); [[UGC National Lecturer]] (1977-78); and [[UGC National Fellow]] (1983). He was elected Fellow of the Indian Academy of Sciences, [[Bangalore]] and [[National Academy of Sciences]] (India), [[Allahabad]]; Chairman, [[National Committee for the International Astronomical Union]] (1978-81); Vice President, [[Astronomical Society of India]] (1976-78); and President, Mathematics Section, [[Indian Science Congress Association|Indian Science Congress]] (1984). <sup>[https://www.insaindia.res.in/detail.php?id=N76-0843 <nowiki>[2]</nowiki>]</sup>
