Biography

Dr. Berdakh Abibullaev received his M.Sc. and Ph.D. degrees in electronic engineering from Yeungnam University, South Korea in 2006 and 2010 under the Korean Government Scholarship program. He held research scientist positions at Daegu-Gyeongbuk Institute of Science and Technology  (2010-2013) and Samsung Medical Center, South Korea (2013-2014). He was also appointed as a research professor at Sungkyunkwan University, Seoul. In 2014,  he received NIH (National Institute of Health,  USA), a postdoctoral research fellowship to join a research project between the University of Houston Brain-Machine Interface Systems Team and a Texas Medical Center in developing neural interfaces for rehabilitation in post-stroke patients.  Currently, he is an Assistant Professor in the Department of Robotics and Mechatronics,  Nazarbayev University,  Kazakhstan. His research focuses on developing robust Brain-Computer/Machine Interfaces for communication and rehabilitation of people with severe motor impairments.

Dr. Abibullaev has considerable research and clinical experience working with patient populations and physicians in applying scientific and technical skills to advance the development of treatments for neurological disorders. His research focuses on developing robust machine learning-based Brain-Computer/Machine Interfaces for communication and rehabilitation of patients with severe motor impairment. 
 
 
Research Area
 
The Brain-Computer/Machine Interfaces (BCI/BMI) research aims to restore or substitute lost motor function in patients with neurological conditions such as stroke, spinal cord injury, amyotrophic lateral sclerosis or in patients with amputated limbs. This technology, which is also known as a thought-translation device, is based on building a direct communication and control channel between humans and an external device without involving any peripheral and muscular activity [1] (see Fig. 1).

BMI systems have already been employed to control external devices, e.g. computer cursors [2] and robotic prostheses [3], using invasive methods.  Moreover, in recent studies, BMIs have been used to control lower-body and upper-body exoskeletons for stroke and paraplegic recovery and rehabilitation via non-invasive approaches [4].

Our research at NU focuses on the development and cross-validation of new neurotechnologies in Kazakhstan to improve the quality of life for disabled people, at the interface between engineering, robotics, and neuroscience.  Currently, we are working on the following research topics:

  • to enable communication capability between brains and computers,
  • to develop neural interfaces to restore human motor functions after stroke.
  • to develop brain-actuated assistive robotic systems for disabled persons

Design and optimization of a Brain-Computer Interface speller in the Kazakh language.

Recently, we have finished the design and optimization of the Kazakh language-based BCI speller on healthy subjects and plan to conduct clinical trials with patients suffering amyotrophic lateral sclerosis (ALS). This research will be conducted in collaboration with the National Center for Neurosurgery in Astana, and it should enable patients to communicate with their relatives, and caregivers via our BCI technology.

Opportunity for students

The undergraduate and graduate students at NU  have an opportunity to actively participate in the projects related to BMI/BCI systems with the investigator. Our lab is equipped with a high-density 64-channel scalp electroencephalography system (Guger Technologies, Austria) with active electrode caps.  The research mentioned is wide enough to create many strong thesis topics for any students who are interested in the research to build novel neural interfaces for different applications.
