Meet the Team

Principle Investigator
Parastoo (Parry) Hashemi
Parry received her MSci degree in Chemistry from King's College, London. She performed her PhD with Martyn Boutelle in the Department of Bioengineering in Imperial College, London where she developed online biosensing technology to measure brain metabolites from human traumatic brain injury patients. After her PhD she skipped over the pond to Chapel Hill, NC in the States where she worked with Mark Wightman. Here she learned fast scan cyclic voltammetry (FSCV) at carbon-fiber microelectrodes (CFMs) and developed the first method to measure serotonin in vivo using FSCV.
After almost 15 years in the States, Parry and her team are back at Imperial, tackling some of the world's most pertinent issues with analytical engineering and have a long list of accolades attesting to their success. Outside of her work and her family, Parry is a flautist and singer in the Gastric Band, a life-long yogi and passionate about increasing representation in STEM.
Post Docs and Graduate Students

Post Doc
Bettina Bohl
Bettina received her M.Sc. in Biochemistry from the Friedrich-Schiller-University Jena in Germany and went on joining the lab of Philipp Koch in Bonn and Mannheim for her PhD. Here she stepped into the emerging field of iPSC-research focussing on neurodevelopment and neurodegeneration. After a first postdoc at Friedrich-Alexander-Universität in Erlangen, Bettina joined the lab in October 2022 as a visiting researcher. Her research will focus on modelling depression in a dish using human iPSC-derived cells and linking the pathology to neuroinflammatory processes. In her free time she likes to go to the gym or play football, to have an excuse to enjoy a really good meal (home-cooked or else) and a glass of wine afterwards.

Graduate Student
Tomas Andriuskevicius
Tomas graduated from King’s College London in 2021, having completed an MSci degree in Computer Science with Artificial Intelligence. He then pursued an MSc degree in Biomedical Engineering at Imperial College London, where he worked on the application of artificial neural networks in classifying serotonin data obtained through fast-scan cyclic voltammetry. Alongside his studies, he also gained 3 years of industry experience as a software engineer. Currently, Tomas is pursuing a PhD project that involves examining the relationship between monoamine levels in skin or hair cells and those in the central nervous system with the aim of promoting mental health. The project is being funded by an iCASE award from the EPSRC, with the support of Proctor & Gamble.

Graduate Student
Anna Rhodes
Anna received her MEng in Molecular Bioengineering from Imperial College London in 2022. She is currently a PhD student in Bioengineering in the Hashemi and Higgins Labs, where she will explore the nature of hair follicle innervation and pursue interdisciplinary solutions to control follicular neurotransmitter release to promote mental wellbeing via the skin-brain axis.

Graduate Student
Naima Adan
Naima holds a Bachelor's degree in Biomedical Sciences and a Master's degree in Bioengineering from Imperial College London, and is currently pursuing a PhD in the Hashemi lab. Her research focuses on the intricate relationship between the gut, brain, and skin. Additionally, she possesses a keen interest in neurotechnology, which drives her to expand her knowledge and contribute to the cutting-edge developments in this field.

Graduate Student
Pablo Prieto Roca
Pablo received his BEng in Biomedical Engineering from King’s College London, , and went on to complete an MSc in Neurotechnology at Imperial College London. During his MSc, he joined the Hashemi Lab, where he began working on morphological analysis of histamine-induced serotonergic neurons. Pablo is now pursuing a PhD project that involves experimental measurement and computational modeling of serotonin neurotransmission in iPSC-derived serotonergic neurons using fast-scan cyclic voltammetry (FSCV). Outside his research, Pablo loves playing tennis, padel and filmmaking.

Graduate Student
Tom Burton
Tom received his MBiolSci in Biochemistry from the University of Liverpool. He then joined the Hashemi Lab as a PhD student, where his research focuses on multiplexing neurotransmitter detection in integrated stem cell models of depression. Outside of his research, Tom enjoys playing football and is a huge advocate for the north of England. You can find him in a beer garden on a sunny afternoon.

Graduate Student
Matthew Murphy
Matthew recieved his BSc in Medical Biosciences from Imperial and then went onto UCL to get a MSc in Experimental Pharmacology and Therapeutics. Whilst at UCL, he formed a collaboration with the Vaccine and Immunotherapy Centre in Boston, affiliated with Harvard Medical School. He then earned an MRes in biomedical research which is where he first joined the lab. Matthew is now a bioengineering PhD student in the Hashemi Lab and his research focus is developing a novel model of the gut brain axis, in collaboration with Korcsmaros Lab. Outside his research, Matthew loves pretty much all forms of physical activity and to eat and travel.

Graduate Student
Charlie Rayner
Charlie previously studied both a bachelors and master’s degree in Natural Sciences at the University of Cambridge. He worked extensively within the Cambridge Centre of Medical Materials, developing implants for vascular and orthopaedic applications. His current project, within the Chemical Biology and Bioentrepreneurship CDT, aims to further utilise this tissue engineerining experience within the world of neurotransmitter detection and characterisation. Outside the lab, he can often be seen playing basketball or going caving.
Masters and Undergraduate Students

MRes Student
Joanna Mialkowska
Joanna graduated with a BSc in Bioengineering from University of California, San Diego, where she focused on processing and analysis of EEG-based biomarkers. After this, Joanna came to Imperial to pursue her MRes Neurotechnology degree and joined the Hashemi lab. At the Hashemi lab, her project focuses on modeling serotonin dynamics from human iPSC-derived serotonergic neurons. She is also investigating novel approaches for filtering and analyzing FSCV data. In the evenings, you'll see her reading in a park, practicing yoga or planning her next road trip.

MSc Student
Taran Jawa
Taran received his BSc in Biochemistry from the University of Bristol and is currently completing an MSc in Bioengineering at Imperial. As a summer researcher in the Hashemi Lab, he is developing an FSCV protocol to simultaneously detect serotonin and insulin from pancreatic release events. His research focuses on decoding the sub-second dynamics and secretory mechanisms of insulin. Outside the lab, Taran is often found struggling with a crossword or diving down a YouTube rabbit hole.

MEng Student
Ho Pak Hei
​Ho Pak Hei is currently a final year Molecular Bioengineering student studying in Imperial College London, and joined the Hashemi Lab in completing the MEng individual design project. Hei’s project focuses on developing a microfluidic device that maintains body-temperature and allows for media and drug exchange during in-vitro electrochemical measurements of human iPSC-derived serotonergic neurons to increase reliability and faithfulness to in vivo environments. During the weekends, Hei enjoys hopping between cafes to do drawings, sketches and sometimes creative writing.
