I am an Assistant Professor in the Department of Electrical Engineering
at the Indian Institute of Technology (IIT) Ropar, India. I have received an M.Tech degree
from IIT Delhi in 2010 and a Ph.D. degree from IIT Bombay in 2017. My
Ph.D. thesis focused on the design and development of low-power and
low-noise analog signal conditioning integrated circuits. From 2010 to
2012, I worked as a Design Engineer in the Advanced Technology
Organisation (ATO) lab of General Electric (GE). From 2017 to
2018, I worked as a Lead Research Engineer in the Corporate Technology
(CT) group of Siemens. My research interest is
multidisciplinary, which includes CMOS integrated circuit design,
neuromorphic electronics, electronic system design for high precision
instrumentation, bio-medical instrumentation, sensors and transducers.
I have published more than ten journal/conference papers as
author/co-author and have filed for several patents. I was awarded the
IEEE ISCAS 2017 International Student Travel Grant Award. I am a
senior member of IEEE and also an active reviewer for many reputed journals,
including IEEE Trans. on Circuits and Systems - 1, IEEE Trans. on Neural Networks
and Learning Systems, IEEE Trans. on Biomedical Circuits and Systems, IEEE Trans.
on Instrumentation and Measurements, IEEE Sensors Journal, Elsevier Microelectronics Journal,
IET Electronics Letters and others.
