For over 15 years, scientists at Ulster University have been developing stimulus responsive therapeutic systems, primarily to address the adverse effects associated with the use of cancer chemotherapeutic drugs. During those studies, the benefits of providing a transient, in situ source of molecular oxygen during therapy became abundantly clear and it was out of this that StimOxyGen was born.


Our Team


Sian Farrell | Chief Executive Officer


Anthony McHale | Chief Scientific Officer

Sian Farrell graduated with a 1st Class Honors MPharm Degree at Ulster University in 2015. Upon completing her pre-registration training at Bristol Royal Infirmary she remained there as a band 6 rotational pharmacist undertaking patient facing roles on oncology wards and gaining experience in specialist aseptic services.

In the final stages of her PhD, Sian began investigating the commercial value of StimOxyGen technology and led the team through ICURe (Innovate UK). With experience in both clinical and academic research settings, Sian has developed a passion for technology transfer from bench to bedside and is determined to improve the lives of cancer patients on a global scale.

Professor of Medical Biotechnology at the School of Pharmacy & Pharmaceutical Sciences at Ulster University, Northern Ireland and based on the Coleraine campus. Research interests are concerned primarily with the design, development and exploitation of stimulus responsive drug/gene delivery systems in areas such as oncology and tissue regeneration.

Dr Les Russell | Director

Thomas graduated with BSci in Pharmaceutical Biosciences from Ulster University in 2018. He then commenced a PhD investigating the development of stimuli-responsive nano- and microparticles for treatment of prostate cancer.
Thomas has extensive experience in formulation science as well as the pre-clinical efficacy testing of new formulations using 2D / 3D cell and murine based models of prostate cancer.

Les was the founding CEO of OrganOx Limited and led the company through 5 funding rounds taking the company from lab stage into full scale clinical trials and commercialisation  and winning several awards for the company. He has more than 40 years experience in the medical device and biopharmaceuticals sectors working at senior levels in both early stage companies and multinational corporations. His passion is working with individuals and teams to bring early stage technology into full commercial use.

Les holds first class honours and PhD degrees in Chemistry from the University of London.
