Tass Lab Team

Peter A. Tass, MD, PhD
Professor of Neurosurgery

Dr. Peter Tass investigates and develops neuromodulation techniques for understanding and treating neurologic conditions such as Parkinson’s disease, epilepsy, dysfunction following stroke and tinnitus. He creates invasive and non-invasive therapeutic procedures by means of comprehensive computational neuroscience studies and advanced data analysis techniques. The computational neuroscience studies guide experiments that use clinical electrophysiology measures, such as high density EEG recordings and MRI imaging, and various outcome measures. He has pioneered a neuromodulation approach based on thorough computational modelling that employs dynamic self-organization, plasticity and other neuromodulation principles to produce sustained effects after stimulation. To investigate stimulation effects and disease-related brain activity, he focuses on the development of stimulation methods that cause a sustained neural desynchronization by an unlearning of abnormal synaptic interactions. He also performs and contributes to pre-clinical and clinical research in related areas.

Research Scholars

Justus Kromer, PhD

Justus Kromer's research is devoted to improving deep brain stimulation techniques causing long-lasting symptom relief in patients suffering from neurological disorders, e.g. Parkinson's disease. Being a theoretical physicist in the group of Peter Tass, Justus Kromer performs computer simulations in order to understand stimulation-induced rewiring of synaptic connectivity in symptom-related brain regions.

During his PhD studies at Humboldt University in Berlin, Germany, he gained expertise in the fields of stochastic processes, nonlinear dynamics, and computational neurosciences. He was trained in both, computational studies and theoretical modelling. His general research is devoted to understanding and manipulating noisy nonlinear systems with application to biology such as neuronal networks and signal processing systems, e.g. sensory neurons and chemotactic agents.


Tina Munjal, MD

Tina is a resident physician in the clinician-scientist training program in the Stanford Department of Otolaryngology - Head & Neck Surgery. She received her undergraduate degree in Biochemistry & Cell Biology from Rice University and her medical degree from the Johns Hopkins University School of Medicine. She also completed a research fellowship at the National Institute on Deafness and Other Communication Disorders at the National Institutes of Health. Prior to joining the Tass lab, her research involved the cellular mechanisms of synaptic plasticity, the molecular genetics of inherited hearing loss, and the optimization of music listening for cochlear implant users. She is now investigating acoustic coordinated reset neuromodulation and other neuromodulation techniques for the treatment of subjective tinnitus. 


Clinical Research Coordinator and EEG Lab Manager

Kristina Pfeifer, BA, MA

Kristina received her Bachelors and Masters in psychology with an emphasis in psycho-physiological research from San Francisco State University. She focuses on analysis of high-density electroencephalography (EEG) data and studies the role of neuromodulation and its effects on abnormal brain activity in Parkinson’s, stroke and epileptic patients. She also performs high-density EEGs and transcranial magnetic stimulation (TMS) in other clinically associated areas.

Clinical Research Coordinator and EEG Neuroscientist

Jessica Kalinova Yankulova, BA, MA

Jessica obtained her Bachelors and Masters in Psychology from San Francisco State University where she specialized in understanding action selection and decision making on a mechanistic level.  Jessica is currently a clinical research coordinator associate working on non-invasive neuromodulation and neurofeedback for patients with neurological disorders such as Parkinson’s disease. Jessica hopes to further her studies and one day pursue a Ph.D. in neuroscience.

Clinical Research Coordinator and EEG Neuroscientist

Ellyn Daly, BS, BA

Ellyn obtained degrees from UC Davis in Neurobiology, Physiology, and Behavior (BS) and Philosophy (BA). Prior to joining the Tass Lab, her research included studying oculomotor mechanisms involved in reward-mediated visual attention and interests in mechanisms of conscious experience. She is studying the role of neuromodulation for patients with neurological disorders.
