In 2001 he became more interested in the subject of mental health and decided to pursue further post graduate training in Mental Health from UK (2004-2006). He came back to India and started independent research in neuro-transmitters specially Serotonin. With the kind help of a fellow scientist Dr Shivshankar, he could use his lab at Indian Institute of Chemical Biology, Kolkata for few months. It was in this lab, he could find out the correlation between Platelet serotonin and human behaviour.
He restarted private practice as a Consultant in Mental Health in Kolkata, India. After the demise of his wife who succumbed to cancer in 2012, his research interest shifted to the relationship between mental stress and cancer. After 6 years of independent research, in 2018, he published a paper titled ‘Hypothesis of a Holistic Treatment of Cancer: Crab method’. He has started to apply his new mode of treatment to only willing cancer patients along with conventional cancer treatments with favourable results.
After the covid pandemic, in 2021, he could start regular platelet Serotonin test on his patients at a well-known lab in Kokata, Pulse Diagnostics. While doing these platelet serotonin tests he accidentally found out that all patients who were mentally stressed did not have high levels of platelet serotonin, some had even low levels of serotonin. Strangely anti-depressants were not of much help in patients with low serotonin. He then conjectured that this ‘non-responsiveness to anti depressant patients’ may have accompanying high dopamine level (Serotonin is inversely proportional to Dopamine). These group of patients responded promptly to anti-dopaminergic medicines. He has summarized his observation in a paper titled “Platelet Serotonin level: its pivotal role in Aberrant Psychological behaviors & Stress Management”.

He is the founder of an organisation “SEROTONIC- MIND”. This organisation endeavours to establish a proper scientific platform where the subject of mental stress can be dealt more rationally. It also conducts various unique ‘mind- training’ programmes under his direct supervision and guidance to help people to face various stressful situations more efficiently without getting much disturbed themselves.
