## Research work

The main focus of his research involves study of circadian clocks in shift workers, cancer patients and cave fish. In addition, he studies cognitive abilities, with reference to short-interval judgment, in human subjects. He also studied cognitive abilities involving case construction behavior in a species of bagworm moth. He demonstrated alteration in temporal organization in human subjects, who carry out rotational shift duties. He reported disruption of circadian rhythm in cognitive judgment of short-time intervals in shift workers. He proposed a model for optimization of human shift work. He reported that shift work might reduce human longevity. He reported disruption of circadian clock in cancer patients and suggested implementation of patient-specific chronotherapeutic protocol. He demonstrated functional circadian oscillators in cave fish and reinterpreted findings of others to rule out the hypothesis of clock regression in hypogean fish. He reported rhythmic pattern in case architecture of bagworm moth. He proposed a model illustrating the ability of this moth to process thorn length and distance signals hierarchically during case construction through toggling its preference between thorns and cut-twigs.
