Suman defended his Ph.D. thesis on January 10, 2023.

Suman’s research centered on creating miniature implantable electrode arrays specifically designed to capture electrical signals within the brains of rats. These arrays, called microelectrode arrays, were used to record two types of brain activity: electrocorticography (ECoG) and depth electroencephalography (EEG), both focused on the somatosensory cortex, the region responsible for processing touch sensations.

He developed high-density 32-channel microelectrode arrays, capturing ECoG signals with exceptional detail (high spatial resolution) across diverse neurophysiological states. This research not only advanced the understanding of Epilepsy in animal models but also shed light on how AEDs combat seizures.

He conducted long-term studies (chronic studies) utilizing a 10-channel, dissolvable (biodegradable) microelectrode array. This design eliminates the need for a second surgery to remove the implant, significantly improving animal welfare.

Additionally, he designed and built a 13-channel microneedle electrode array made of silicon. This array allowed him to study the variations in local field potentials (electrical activity within a specific brain region) arising from the somatosensory cortex under normal and seizure conditions in short-term (acute) experiments.

Suman’s research also introduced a cost-effective and efficient data acquisition system: the OpenBCI Cyton Daisy Biosensing Board. This is the first reported use of this system for in vivo recordings in animal experiments, demonstrating its potential as a viable alternative.

BEES Lab wishes him continued success in all his future endeavors!
