Joshi completed her undergraduate education in 2017 at Birla Institute of Technology and Sciences, Pilani, India. She’s currently studying in the Department of Biomedical Engineering, Case Western Reserve University, and started in August 2021.

Her PhD project focuses on understanding the effects of proprioceptive modulation on basal ganglia circuitry. She is particularly interested in using electrophysiological measures such as single-unit recordings, local field potential recordings along with EEG to understand the interactions between the basal ganglia and other parts of the brain. The project aims to understand these effects and use them as a tool for developing non-invasive disease interventions.

Aratrik Guha, Department of Biomedical Engineering, Case Western Reserve University, August 2022 – present


Guha is researching deficits in spatial navigation of Parkinson's patients who are both on a clinically viable dosage of Levodopa and bilaterally implanted with deep brain stimulators (DBS). 70% of fatalities within this patient population stems from backwards falling in visually noisy environments. We believe the chief suspect is a mismatch in sensory encoding of vestibular and ocular signals. To test this, we will utilize a battery of varying neuromodulation using Medtronic's DBS: Percept, from which we will acquire local field potentials, and psychometrics, which we are investigating using a 6-axis flight simulator (vestibular stimulus) and a VR headset with 200 Hz eye tracking (visual stimulus). Previous work suggests that Parkinson's patients have compromised visual and vestibular sensation without pairing stimuli, hence the question, how do these stimuli affect perception in concert.

Varun Reddy Gopu, Department of Biomedical Engineering, Case Western Reserve University, January 2023 – present


Reddy Gopu’s research is based at the Cleveland Clinic and the Veterans Affairs Hospital and focuses on research techniques involving eye movement analysis to predict amblyopia using stacked Machine Learning models, which includes the combination of Random Forest, SVM, and Gradient Boost Classifier. To achieve this, we have identified nine different strategies, such as quick phase, microsaccades, staircase, and primary saccades. His project aims to find a pattern to recognize the correlation between the velocity and amplitude of saccades, as well as to identify the role of the central nervous system in the pathophysiology of abnormal eye movements, gaze holding deficits, and strabismus. Additionally, at the Veterans Affairs Hospital, we plan to predict the pattern of falls and freezing gait and establish a relationship between eye movements and fall patterns in Parkinson's patients by gathering and analyzing data from wearable devices.
