Jesin's main research areas are speech signal processing, under-resourced languages, machine learning and engineering education.

During 2012-2014 she worked on developing a Text To Speech synthesis system in her native language, Malayalam (language spoken in south India), with special emphasis on developing a prosodic model for the same. Further, during 2014-2016 she worked as a Lecturer in Electronics and Communication Engineering in India, during which she was involved in some student projects that have been published and presented to wider audience. In 2016, she joined University of Auckland as Ph.D scholar in the computer systems engineering. For her PhD, she worked in the Healthcare Robot project (part of CARES, University of Auckland), with special focus to improve the naturalness of the synthetic speech and incorporate empathy into the robot voice, to further improve its acceptance.

Jesin strongly believes that if you can combine your passion with your career, you will never feel that you are working. Engineering offers the possibility to combine your passion with technology and make a difference. Jesin enjoys languages, music and interacting with people - and being a lecturer in Electrical, Computer, and Software Engineering working on speech technology for languages is definitely tying everything up nicely.

In terms of her education philosophy, she tries to advocate the Māori concept of ako (The concept of ako describes a teaching and learning relationship, where the educator is also learning from the student and where educators’ practices are informed by the latest research and are both deliberate and reflective) in her teaching.

Jesin is originally from Kerala, India. Malayalam is her mother-tongue. She currently lives in West Auckland, New Zealand with her husband.
