Dr Nikesh Bajaj

Profile

Nikesh Bajaj is a Lecturer in Data Science at Queen Mary University of London, for a Hainan Program. Nikesh worked as a Research Associate at Imperial College London, in National Heart & Lung Institute (NHLI) from 2021 to 2023, and currently associate with Imperial as an Honorary Research Associate. His research work at Imperial is involved Electrocardiography Imaging (ECGI) inverse problem and quantifying the organisation of electrical activities of the heart. During 2019 to 2021, Nikesh worked as a Research Fellow at University of East London, on a Innovate UK funded project - Automation and Transparency across Financial and Legal Services, in collaboration with Intelligent Voice Ltd., and Strenuus Ltd.  The work was focused on Deception Detection in Conversations using Linguistic Markers, which produced a Patent along with a few publications.

Nikesh completed his PhD at Queen Mary University of London, UK and University of Genova, Italy, in a joint program. His PhD work was focused on Predictive Analysis of Auditory Attention from Physiological Signals – PhyAAt. Nikesh also has a 5.5 years of teaching experience in a university in India, which included courses and labs on Signal Processing.

Nikesh is also a mentor and a consultant (alpha testers) at Deeplearning.ai for courses & specializations offered at Coursera, such as NLP, GANs, Tensorflow, MLOps. Nikesh has a few python libraries, such as spkit, phyaat, pylfsr.
