# Parastoo Hashemi

Parastoo ("Parry") Hashemi (born 1980) is an Iranian-British neural engineer at Imperial College London.
Hashemi's research develops and applies sensors for brain measurements of neurotransmitters in the context of mental illness etiology, diagnosis and treatment.

## Life and academic career
### Early life

Hashemi was born in Tehran, Iran and immigrated with her family to the United Kingdom, as a child, in 1986. She grew up in Durham, UK and attended Belmont Comprehensive school and Durham Johnston 6th Form College.
Hashemi graduated with a first class Master in Science (MSci) degree in chemistry from King's College London in 2003. She received her PhD in Bioengineering from Imperial College London in 2007 under the mentorship of Dr. Martyn Boutelle. The focus of her Ph.D. research was to develop online microdialysis techniques for monitoring humans with traumatic brain injury.
Hashemi moved to the United States in 2007 to perform her post-doctoral work with Dr. R. Mark Wightman at the University of North Carolina at Chapel Hill. The focus of her post-doctoral research was to develop a selective method for in vivo detection for brain serotonin.

### Positions held

Hashemi held an assistant professorship in the department of Chemistry at Wayne State University from 2011 to 2015 and in the department of Chemistry and Biochemistry at the University of South Carolina from 2015-2022 where she was tenured in 2017. Hashemi continues to run her lab as a Reader in Brain Diagnostics and Therapeutics in the Department of Bioengineering at Imperial College London since 2019.

### Research

Hashemi has pioneered tools for measurements of serotonin in the brain, a neurotransmitter important in the pathology of depression. Her team is using these tools in a variety of models to better understand, diagnose and treat mental disorders, with a focus on depression.
