Can you give us a little background about yourself?
I have done my Bachelor of Technology from G.B.Pant College of Technology, Pantnagar, Uttarakhand, India in 2006. I have been with Telco Construction Equipment Company limited, which is a joint venture between Tata Motors (India) and Hitachi (Japan) from July 2006- July 2007. I was with Hindustan Petroleum Corporation Limited from September 2007- July 2008. From July 2008-June 2013, I have been University of Calgary, Canada where I have received my Ph.D. and postdoctoral work. I was with the Ohio State University as Research Scientist under DARPA/ Rockwell Collins funded project from July 2013 to June 2014. Since then I am with I.I.T. Roorkee India as an Assistant Professor.
How did you become interested in Electrical Engineering?
The scope of electrical engineering spans from power system engineering, dealing with bulky transformers and power transmission lines to microelectronics. I have been initially fascinated by robotics and automation field and wanted to pursue it via engineering. During engineering I competed in few robotics competitions and won most innovative robot prize in national level competition hold by my university. Such small recognitions were enough to boost my desire to pursue further in this field, which motivated me towards my first industrial job. During my Ph.D., while studying about various artificial intelligent networks such as neural networks and fuzzy logic, I further understood its various applications utilizing digital control.
Specifically, I liked the application of linear/nonlinear filters in software-defined radios where the effects of hardware imperfections can be actually compensated in digital domain. It also provides re-configurability, portability and flexible solution in a small package.
Can you tell us about your work as an Assistant Professor in the Electrical and Communication Engineering at the Indian Institute of Technology Roorkee?
Currently I am pursuing the theme of highly power and spectral efficiency communication, which utilizes software-defined radios for distortion mitigation arising during practical implementation. My team of students had worked on low cost FPGA implementation of digital solutions for distortion arising from PA nonlinearity, modulator imperfections, multiband transmission for carrier aggregation proposed in 5G communication and MIMO diversity techniques. The main thrust is on practical implementation, which can be utilized as a viable product as opposed to solely theoretical investigation commonly favored in academia. Atmosphere in India is ideal for such endeavors in current scenario.
You received many awards and recognitions. What were your secrets that lead you in achieving those awards and recognitions?
I would quote Geeta, do your job without expecting the outcome, as outcome is not in your hands. I think if there is any secret, it should be in not working for awards but for work itself and enjoy it. Awards are additional perks.
What jobs and experiences have led you to your present position?
All experiences add to the learning. Technically, I have learned a lot in University of Calgary under eminent professor, Dr. Fadhel Ghannouchi as student and then postdoc. Several publications have been resulted from this work. Apart from technical knowledge, I learned skills such as time management, proposal/patent writing, and managing/ guiding students. My experience as research scholar in Ohio state university under Proff. Patrick Roblin has also contributed significantly towards handling projects within industry deadlines. Most of my awards have been given to the work done in OSU due to its novelty and futuristic appeal.
What is your main research interest? Can you tell us more about it?
My main research interest is application of signal processing concepts in innovative applications. For example, have tried to use correlation criterion to utilize two different signals while using single hardware for capturing them. It will lead to reduction hardware requirement, which can be very useful when we are trying to reduce size in chip level implementation. Currently I am focusing on RF front-end performances under latest communication standards. High peak to average power ratio of signals puts some constraint on full utilization of transmitter amplification capability and I am pursuing digital compensation schemes for such application.
Do you participate in professional organizations? Can you tell us about it?
I am member of IEEE from past 7 years and I participated as reviewer, Technical program chair and event (workshop/short courses/lecture) organizer from time to time.
IEEE is most popular forum for electrical engineers and is increasing in size and activities every year. Participating in such events results in new collaborations, knowledge sharing, and platform to showcase your technical potential.
What do you usually do during your free time?
In my free time, I like to read Sci-fi fiction such as Michael Chrichton, Jule Verne, Robin cook and James Rollin. Such fictions based on facts makes me wonder about potential of Science and engineering.
Few years from now, what direction do you see yourself?
As a profession, being a professor can be very rewarding intellectually and provides lots of freedom. However, I hope to see some of my research work converted to product and being used by common people. As opportunity arises, productization can be via companies, which allow me research freedom, or it can be spin-off.
As a professor, what words of encouragement would you give to your students?
I always say to my students that, ‘just do’. If not big, do something small. If this is not working, try that. Do whatever you like the most. Whether it is research, teaching, business, or management. Efforts are rewarded sooner or later. I believe that life is not unfair, but sometimes it is delayed in giving your dues.
