About me

Hi, my name is Mikolaj Kegler. I am a final-year PhD student in the Department of Bioengineering & Centre for Neurotechnology at Imperial College London (ICL). I am a member of the Sensory Neuroengineering group led by Prof. Tobias Reichenbach.

My PhD research focuses on understanding neural mechanisms underlying perception and comprehension of natural speech, especially in challenging listening conditions. In my work, I am combining computational modelling with neuroimaging and non-invasive brain stimulation to understand how natural speech is processed across human auditory pathways.

Apart from my neuroscience research, I am a scientific advisor at Logitech and develop deep learning algorithms for speech signal processing. An interactive demo of our latest project, Deep speech inpainting, is available here. I am also a graduate teaching assistant in a range of computational courses at ICL.

Currently, I am working as an Applied Scientist Intern at Amazon Lab126.
