About the Investigator

Dr. Margo Straka graduated summa cum laude from the University of Minnesota, double-majoring with Bachelor of Science degrees in Physics and Chemistry. In 2013 she received her Doctorate in Biomedical Engineering from the University of Minnesota (advisor: Hubert Lim). Her thesis concentrated on improving stimulation strategies and implantation locations for the Auditory Midbrain Implant by better understanding the central auditory system.

In 2014, Dr. Straka was recruited as a postdoctoral fellow by Dr. Shreesh Mysore to work at John Hopkins University (JHU). At JHU, she worked on unraveling the neural underpinnings of competitive selection in the midbrain. Using iontophoresis in in-vivo neurophysiology experiments, she investigated how the midbrain attention network encodes a signal in the presence of a competitor by probing the interactions between specific nuclei. This interaction is important in bottom-up attention, and may play a role in various conditions with impaired attention such as ADHD and schizophrenia.

In 2016, Dr. Straka accepted a position as a staff scientist at the Feinstein Institute for Medical Research, where she joined the Center for Bioelectronic Medicine with dual affiliation with the Neural Bypass and Pre-Clinical Device Lab.

Research Focus

The nervous system is a complex, interconnected circuit which carries and processes information about every part of our body. Electric pulses from our nerves become transformed into complex signals in different areas of our brain to define our senses, drive our thoughts, and monitor our vital organs. In diseased or injured states, neural signals are often insufficiently communicated from nerves to the brain, from the brain to the nerves, and/or within different areas of the brain. Neuromodulation devices seek to change aberrant activity or replace missing signals, but in order to be effective, we must first understand how neural signals encode information.

Throughout her career, Dr. Straka has sought to decode neural signals in order to better understand normal brain function and mitigate damage from injuries or diseases. She accomplishes this by using various electrophysiology techniques and computation methods. In the Pre-Clinical Device lab, she investigates neural signals in animal models and tests how these signals change with external stimuli or with an injury over time. In the Neural Bypass lab, Dr. Straka is developing software and hardware components of the system that translates neural signals to functional movement for paralyzed patients.
