nDash Writer Profile for Ujwal Chaudhary

Headline

Highly experienced science, technology and medical writer

About Me

I graduated with Ph.D. in Biomedical Engineering in 2013 from a University in Miami, USA. In Dec. 2013, I started working as a postdoctoral researcher at the University of Tubingen and worked until Dec. 2021.

I am an avid writer, and throughout my scientific career, I delivered several scientific study protocols for approval by the institutional review board (IRB) in the US, the ethics committee, and BfArM in Germany. I have published 50+ scientific publications, many of them in high-impact factor scientific journals such as Nature review Neurology, Nature communications, Scientific Report, and Sleep, among others. I have extensive experience in technical and medical writing.

Brain–computer interfaces for communication and rehabilitation

Brain-computer interfaces (BCIs) use brain activity to control external devices, thereby enabling severely disabled patients to interact with the environment. In this review, we provided an overview of the development of BCIs and the current technology available before discussing experimental and clinical studies of BCIs.

Neurophysiological aspects of brain-computer-interface (BCI) control in paralysis

In this article, we discussed: (1) the fundamental neuropsychological learning factors and neurophysiological factors determining BCI performance in clinical applications; (2) the difference between LIS and CLIS; (3) recent development in BCIs for communication with patients in the completely locked-in state; (4) the effect of BCI-based communication on emotional well-being and quality of life; and (5) the outlook and the methodology needed to provide a means of communication

Spelling interface using intracortical signals in a completely locked-in patient

In this article, we reported the implantation of two 64 microelectrode arrays in the supplementary and primary motor cortex of a patient in a completely locked-in state with ALS. The patient modulated neural firing rates based on auditory feedback. He used this strategy to select letters one at a time to form words and phrases to communicate his needs and experiences. This case study proved that brain-based volitional communication is possible even in a completely locked-in state.

Experience

Software Engineer

Company: Infosys Technologies Limited

I worked there from 6/2006 until 6/2008

Graduate Researcher

I started my research and writing career as a doctoral student at Florida International University (FIU) in 2008. I worked extensively in the field of functional near-infrared spectroscopy (fNIRS) instrumentation and the optical imaging of the brain. During my doctoral study, I wrote several institutional review board (IRB) protocols, peer-reviewed scientific publications, and conference proceedings. I was awarded the "Outstanding doctoral degree graduate award" for my doctoral dissertation.

Company: Florida International University, Miami, USA

I worked there from 8/2008 until 7/2013

Postdoctoral researcher

My Post-Doctoral work involves developing and applying a simultaneous fNIRS and EEG-based Brain-Computer Interface (BCI) system to help ALS patients communicate. During my post-doctoral research, I wrote several clinical trial protocols for approval by the Ethics committee. I again published several peer-reviewed scientific publications and conference proceedings, many of them in high-impact factor scientific journals such as Nature review Neurology and Nature scientific Reports, among others.

Company: University of Tuebingen, Germany

I worked there from 1/2014 until 12/2021

Scientific Researcher

The research aimed to develop an invasive auditory Brain-Computer Interface (BCI) for communication in locked-in and complete locked-in state (CLIS) patients. I wrote the study protocol for approval by BfArM, medical equivalent of FDA, in Germany. I again published several peer-reviewed scientific publications and conference proceedings, many of them in high-impact factor scientific journals Nature Communications, among others.

Company: Wyss center for Bio and Neuroengineering

I worked there from 1/2019 until 1/2021
