Prof. A. S. Moharir

Our beloved colleague Prof. A. S. Moharir, who was working with our department, passed away in Mumbai on 01st  March 2019. The department and the institute deeply mourn this sudden death. A brief profile of Prof. Moharir is given below. We invite people who have been associated with him, in any manner, to pay tributes and recall fond memories, by communicating through this page, for others to read and cherish.

PROFILE:Professor. Arun Sadashiv Moharir was born in 1953. He has completed his B.Tech from LIT Nagpur in 1975 and M.Tech from IIT Kharagpur in 1975. He completed his Ph.D from IIT Kanpur in 1981.Initially, he joined IIT Kanpur as a Research Associate and then he was appointed as a Lecturer at University of Roorkee (Now IIT Roorkee). In 1988, he joined IIT Bombay as a Senior Research Engineer in CAD centre of IIT Bombay. Later, he served as Associate professor in our department for a period from 1990-1994, and as a Professor for the last ~24 years.

His research areas were Mathematical Modeling, Simulation, Optimization and Control of Chemical Processes, Reactor Modeling, Adsorptive Separation Processes, Computer Aided Design and Engineering, Process Plant Engineering, Piping Engineering.He was a very inspiring teacher, much involved in the teaching of courses in the design stream, Chemical Reaction Engineering, Process Simulation, Optimization. He earned heaps of praise from the students he taught.Prof. Moharir also served the Institute as Professor-in-Charge of Continuing Education and Quality Improvement Program.

Prof. Moharir conceptualized and developed a novel course on Piping Engineering course, which has impacted several working professionals in the Industry. This course on a subject very critical in design and engineering of any chemical process plant, has been running since 1992 The course has trained close to 10000 engineers from 400 Indian and Overseas corporates so far and has completed 74th edition and he was also planning to hold its 75th edition in May 2019.

Prof Moharir was supported in all his endeavours by his wonderful family, Mrs. Sarita Moharir and his two daughters Sharayu and Manjiri.We pray that his soul rests in peace and for all strength and fortitude to his family to bear this grievous and irreparable loss.

Brilliant young professor at University of Roorkee

Prof. Moharir taught us Numerical Methods and Basic Programming in one course, way back in 1985 at University of Roorkee. We did not have access to computers then as we had just one Main frame computer in our computer center, and after 30 minutes of wait we would get 5 minutes with our cards to run our programs. Five minutes used to get over in pressing just a few keys as no one had seen layout of a keyboard before. Prof. Moharir overcame all these limitations by beautifully combining in his classes numerical analysis, flow of calculations, and logic followed in programming to reach the end result. He asked us to develop programs in our assignments, which he commented and graded! It required a lot of effort from his side, but he put in everything. It is through his commitment to teaching that I later found to my surprise (when I needed it) that he had developed in us the ability to write reasonable computer codes for numerical computations.

When we learnt that he would soon be leaving UOR to join IIT Bombay, we knew UOR had lost a great teacher! I had wished to meet him someday in my visits to IIT Bombay and thank him for the effort he put in, as I never forgot his commitment to teaching. But, I am too late.

R.I.P. Prof. A.S. Mohharir

I am a retired faculty member from the Aerospace Engg. Dept. of I.I.T. Bombay. I may be pardoned for the extreme delay on my part owing to my late knowledge of the unfortunate happening. Much has been already said by way of the glorious tributes paid to Prof. Moharir mentioning his high level of competence and ahievements in the pofessional and academic feilds. The human side has also been highlighted very feelingly by those who came in contact with him through work. No doubt he deserved all the accolades as an extra-ordinarily talented engineer, teacher, researcher and human being. Others like me who were not connected with his work got the glimpses of his unparalleled wisdom, wit and literary flourish through the missives he directed to a non-official forum for communication among faculty. Not a single post without substance and purpose, not a sentence without impact value and not a word misplaced. Whether in regard to a technical subject of common interest, perceived authoritarian high-handedness or practice of bigotry in any form, this beacon of enlightenment and vision never failed the expectation. One cannot just cite another example of clarity of thought and expression! Let me narrate a minor incident as an example from my personal experience about how gracefully Prof. Moharir dealt with issues. Once when he was one of the expectant applicants for family accommodation in the institute campus, the seniority list got messed up due to oversight and he had to be informed about rejection of his claim at the elevanth hour as the same was challenged by another applicant on technical ground. I was administering the process as a corporate responsibility and lo, how Prof. Moharir rescued us by giving his acceptance playfully and also complimenting us for transparency of the process and wishes for 'happy moving in' for the finally successful allottee! Decency all the way without sacrifice of principles! I also remember his public reading of a long eulogistic prose he wrote in marathi for his meritorious daughter. Surely he must have been an ideal family man! Rest in Peace Prof. Moharir, you are a rare example of meaningfully lived life!
Prof. R.W. Shende (Retired)

My heartfelt condolences and Tribute to Prof Moharir

I was 5 yr Integrated M Tech Student from 1991-96 in I.I.T Bombay, He was my Guide in M Tech 1 year long Project. I still remember while writing my thesis he shared his thesis for reference. That thesis was well written and It raised my bar for writing a structured/lucid thesis.He also shared his world class piping engineering course notes...
He was a very kind and noble soul. I remained in touch after my graduation for 4-5 years and he was kind enough to reply my emails...
Without him, IIT Bombay, CAD center, Chemical engineering department will never be same again. His presence and positive energy will be missed...I regret that in i should have met him during my last visit India.

May your soul rest in peace.

Brilliant Professor, True Guide, a great HUMAN & Chill Man...

I am working L&T and based in Dubai from quite some time. I was just now talking to niece who started her intern training in Chemical department at IIT Mumbai, to ask her if Prof. Arun Moharir is there. I will contact him if any help is required. Then, I browsed this page and ..... ohhhhhhhhh...... this sad news......
I always remember Sir as "the best Prof." I ever met in my life. I feel extremely fortunate to meet him during two weeks CEP (piping engineering course) in 2008. What a fantastic way of teaching, always on time, prompt in response, caring, hand holding, making complex things simple, joke in every class and above all a good human being. All my batch mates became big time of Prof. Moharir in short time. In fact we are amazed to note that this course has completed 74 editions. He also shared in one of the session that he worked on piping design for newly built Antilia, Ambani's family house and also helping Mumbai municipality for some critical piping network. He was working diversified and complex projects all through his life. He contributed a lot for the career of thousand of student and helped several industries in India. May God bless and comfort his family during this difficult period.

We love you Sir, will never forget you and will try to contribute in the best interest of our nation the way you have done. Country have lost a intellectual, a brilliant person... irreparable loss....

A Personal Memorial with Prof. Arun S. Moharir

I was the doctoral student under Prof. Arun S. Moharir’s supervision at IIT Bombay from 2009 to 2016. Back in 2007, I was touched by sir’s teaching skill while attending “Piping Engineering” course at IIT Bombay Extension Centre at Ahmedabad. My teaching style had improved after attending his two-week long piping engineering course. When I got admission under QIP category at IIT Bombay, I approached Prof. Moharir for supervision role, and he immediately accepted me as a doctoral student. I started my course work in July 2009, and scored 10 out of 10 SPI in the first semester, Prof. Moharir was more than happy and proudly announced at various research group meetings.

I had attended all of his undergraduate courses between 2009-2012 at IIT Bombay as an extra student in classes without registration. His teaching style was very different. I myself had taught Chemical Reaction Engineering, but the way Prof. Moharir had taught it in IIT Bombay not only impressed the budding chemical engineers but puzzled me also. The simplicity of explaining a complex concept at a time was his forte, as designated by Prof. Moharir at “Granule”. He also used to deliver evening classes to final year chemical engineering students on process design and piping engineering to help them have a better chance at cracking final year company placement interviews.

We had invited him for various expert lectures in Gujarat and conducted a special batch of piping engineering course for faculty members in 2013. He was also a keen observer of human nature and common pedagogical mistakes faculty members make while in class and he delivered a lecture on same to 200+ faculty members at Ahmedabad. He also gave a lecture at pre-vibrant Gujarat summit again on pedagogy.

Currently, I am heading startup and innovation activities across the Gujarat state, but during one of the class lecture in last 5 minutes, he explained a concept and asked all the UG students to start their own consulting firm based on new concept he just explain, and not to look for job, truly, he was ahead of our time in thinking.

One thing he showed me to put yourself in other man’s shoe, and then imagine what it will look like. He explained to me the concept of Distributions, Green’s function, Functional Spaces, Operators etc. from the generalized concept, pointing the commonality in algebraic, ODEs, and PDEs. He used to explain complex concepts based on the vigor of modern mathematics at ease. A strong person from mathematical fundamentals, he always encouraged us to see the truth from the mathematical perspective and present it.

A task-master of all time, he always completed what was promised for the meeting, writing, materials, and personal guidance. He loved his students from heart, never to show it. He understood our problem, all the time, even before we explain it to him verbally, and an elegant solution is always available. Many a time, my complex derivations involving 25 odd pages, he pointed out mistakes in 20 seconds. He always replied to my email and messages in less than 5 minutes. Even 6 months back Sir took the pain to point out the mistake in my code for my research project. I never felt that I had graduated from IIT Bombay, he was always with me for guidance and support.

He will be missed always but will live forever in the many hearts and minds of all UG, PG, and Ph.D. students, trainees of his famous course and faculty members of IIT Bombay. At a personal level, I had lost a fatherly figure but hope to carry forward the clarity, sanctity, and spark that he carried.

RIP to the coolest prof. Moharir

This news was shocking to me. I remember when I met him in my 8th semester engineering course. I saw him cracking Marathi jokes in class and telling us funny stories about his life. He was very down to earth professor and always solved our doubts. The thing which I will never forget about him is the mail reply to one of my batchmates when he was panicked cause of late assignment submission. He wrote 'chill and Peace Yo' ( the trend happening in campus at that time).
Last but not least he saved me from getting DX and I am truly thankful to you sir. We all miss you and RIP.

He is irreplaceable..!!

I met Sir in Nov, 2011 and never realised he will change my life. He came to my life like a star. He made me realize how important is to be responsible, punctual, organised and to be always correct. I am his last PhD student and my motivation and effort was just because of his untiring day night support he gave throughout stay at IITB. He is a father figure to me who not only taught Chemical Engineering, but also groomed to live a dignified life. He used to tell me “I feel proud, when females prove professionally and live life on their own terms and conditions”. He was one point solution to all problems. He never asked us to write emails or share the draft. One Watsapp message and he is in the lab. He used to sit with us for long hours and when unable to do so we used to get Watsapp messages with solution/text/derivations. I still remember many times messages were so long, we have to take help of word document to understand them. For work there were no excuses with him.

I am indebted to Professor for all he did and taught both academically and to be a better human being.

His FB fan page

In 2010, FB was still relatively new. There was this concept of having fan pages of virtually everything. Amid fan pages of movies, music bands, celebrities, one fan page stood out: that of Prof. Moharir. I can't think of any other professor from institute, let alone department, who had a fan club page on fb at that time. Might seem immature and silly but it spoke volumes of his popularity among students. Once after cracking a joke in class he told us that he was popular as 'fatta king' among his friends in his college time. Of our memories of classes during college time, best ones are from his classes. He will be dearly missed.

Here's his fan page: https://www.facebook.com/Moharir-Sir-Fan-Club-147805595260236/

Moharir Sir was my fav. teacher

Moharir Sir taught us reaction engineering in our third year. It was the first time I started to develop some love for chemical engineering. If it were not for him and his teaching methods, I would never have gotten a PhD in Chemical Engineering. I was taught by many other professors after him and they made me realize how good of a teacher he was - he gave students some very basic concepts, gave them time to think in class.
His passing away is a big loss to the department, to iitb and to the field of chemical engineering.

Coolest Professor of IITB

Moharir Sir was one of the coolest professors of IITB. I recollect one incidence when I emailed him my concern over delay in submitting an assignment. I expected some scourge, but all I received in reply was a candid "Chill" :).

A large part of my Chem-IITB memory is because of Moharir Sir. You will be missed Sir! Rest in Peace!

A REVERENTIAL SALUTE TO A CRUSADER

The sudden demise of Prof.A.S.Moharir has come as a shock to all who had known him closely for the last three decades. The hallmark of his personality has been his indomitable , never say die spirit . This sprit has not only helped him to chart a successful academic career at IITB but also wage a long battle with courage an ailment which struck him during the later phase of his career.
Prof. Moharir had joined the CAD Center on 27 November 1986 when the Centre was in its growth phase. During his long association with the CAD Centre , he played a decisive role in helping the Centre to reach the status of a self-supporting centre with strong industry bonds. He came to the CAD centre with an expertise in the area of Reaction Engineering with the added experience of having developed a rigorous model for FCC. He could quickly get on to work on some modeling and simulation problems for the chemical industry , the most notable has been the rigorous model he developed for the multi-bed SO2 to SO3 converter of the Dharamsi Morarji Sulfuric Acid . The simulation model for the Sulfuric Plant had won approval from the top echelon of the company for its fidelity .He joined the faculty of Chemical Engineering Department on 6th November 1990. He was able to balance his academic commitments in the department with the industry centric developmental efforts in the Centre . His reactor modeling work continued with model development for a fat splitting plant in the Minor Oil Refinery of Hindustan Lever. On the academic front, he has been pursuing research in the area of adsorption with special focus on PSA. He was able to develop a rigorous model for PSA which he could validate through numerous laboratory experiments and plant data. With the rich experience he had gained from this exercise, he could help a large number of industries to tackle problems in their adsorptive separation systems . Using this well tested technology , he could provide large number of medical oxygen prototypes to IPCL. On the reactor modeling front, he had also gone on to develop a general reactor modeling framework using OOP principles. He had undertaken a number of modeling , design and simulation problems for UOP. An interesting problem he had undertaken for UOP was to develop an enhanced version of a Process Invention Package initially developed by Prof. J.M. Douglas of University of Massachusetts.
Responding to chemical industries clarion call for a comprehensive training programme in Piping Engineering, Prof. Moharir had conceptualized and nurtured a training programme which has been a judicious blend of science, engineering practice and technology assisted learning . The participants were exposed to contemporary computer aided design tools for piping design and analysis enhancing their employability. This programme has been a resounding success and has established a record of sorts based on many metrics . For the industry, he had also solved some interesting steady and transient flow problems in pipes and piping networks.
Prof. Moharir , in his passion to pursue new initiatives, has often expected from the system more than it could possibly offer . This has caused some frustration in him from time to time . These did not put a damper in his crusade to explore interesting technology development ideas which had not only enriched the academic knowledge domain but had also enhanced industry competence.
There is a benevolent student centric side to Prof. Moharir’s character. He took pains to ensure that his courses resonated well with the academic aspirations of the students. He had often provided opportunities to young graduates to enhance their professional skills through participation in his developmental projects.
If I were to write an epitaph on Prof. Moharir’s eternal resting place, I would simply state ‘ here was a man who gave his best to the institution he loved most’. In his demise, the department lost a dedicated academic, the student community an inspirational teacher and the industry, a dependable problem solver. It has been my privilege to be his colleague and friend for over three decades. I pray that his bereaved family will have the strength to bear his loss. May his soul rest in peace
