Professional portrait of Abhay Koushik

Abhay Koushik

Engineer. Neuroscientist

Working across: Computational Neuroscience, Machine Learning Systems, Biosignal Processing, Embodied Intelligence.

I research & develop systems that interpret brain, body & behaviour to support human well-being.

Working Territory

Complex signals. Human questions.

I work with EEG, neuroimaging, physiological rhythms, behavioural data, and full-body movement to investigate sleep, cognition, perception, and bodily regulation—and to build tools that make these processes more interpretable.

Across Research and Product

From exploratory code to working systems.

My work spans research laboratories, startup R&D, behavioural experiments, neuroimaging studies, and rapid prototypes. The recurring task is turning an uncertain question into an analysis, experiment, or system that can be tested.

Neurotransmitter-Informed Connectivity

Implemented a MATLAB pipeline connecting EEG and fMRI connectomes with normative PET maps, using quantile filtering, randomized spatial controls, and mixed-effects modelling.

ProblemCan neurotransmitter geography help explain functional connectivity and pharmacologically induced network change?
Outcome
  • Enabled completion of the multimodal pipeline implementation investigating drug effects as part of my lab rotation
  • Contributed as a co-author to the broader Neurobiological Organization of Functional Connectivity study.

Industry Direction

Rigorous research. Usable technology.

I work best where complex human data, scientific uncertainty, and technical development meet—turning difficult questions into evidence, prototypes, and systems that can be tested in the real world.
