[5] Leaving POSTECH in 2001, he went to the Korea Institute of Science and Technology (KIST) to be a principal research scientist, a position he held for a decade.

He has been defining the physiological roles that a group of genes play in vivo, whose functions are known to be critical for regulation of intracellular calcium dynamics.

[10] Shin has been particularly interested in defining the functions of voltage gated calcium channels in normal as well as pathological states of the brain.

[11] The thalamus is the gateway through which all the somatic sensory information from the periphery must pass through to reach the cerebral cortex, where perception is achieved.

Shin has also shown that the same mutant mouse was resistant to absence epilepsy, a disease characterized by a brief loss of consciousness accompanied by abnormal EEG findings.
